In the event of significant and loss of flooring performance properties
Self-leveling floors have special characteristics, among which are durability, wear resistance, chemical resistance, elasticity, tightness, resistance to vibration. In order for self-leveling floors to retain all consumer properties for many years of operation, it is necessary to strictly follow the technology in work. However, active use, time of use, unexpected mechanical stresses can lead to partial damage or high wear.
In this case, self-leveling floors are being repaired, which also requires compliance with the technology and the implementation of all stages of work.
Stages of self-leveling floors repair
When places of greatest abrasion become visible on the surface of the self-leveling floor, mechanical damage, the repair of self-leveling floors begins, which includes several stages:
- on the detected weak area, the coating that is not tightly adjacent to the base of the floor should be removed;
- carefully level the surface of the base using milling and grinding;
- "embroider" the cracks, fill them with a repair mixture;
- remove the resulting dirt with an industrial vacuum cleaner.
In this case, materials are used that are as compatible as possible with the base material of the floor in order to ensure the best adhesion to the concrete base and parts of the coating.
Elimination of defects in the process of repairing self-leveling floors
During the operation of the self-leveling floor, defects may appear associated with a violation of technology or with the low quality of the materials used. In this case, it becomes necessary to organize work to eliminate the defects that have appeared.
The main defects are:
- peeling;
- roughness;
- partial whitening of the surface;
- flaking;
- crack formation;
- the appearance of grains;
- the appearance of bubbles.
In any case, part of the coating is completely removed at the site of the defect, the concrete floor is cleaned, and a new coating is applied. It is necessary to completely remove problem areas, find and eliminate the cause of defects, re-prepare concrete base, only then apply a new layer.
When grains appear, when whitish spots appear, the damaged part of the surface should be treated with a grinding wheel, after which a repair layer of material should be applied.
Compliance with the technology will lead to long-term flawless operation, when the floors will show all their properties. Then the repair of self-leveling floors will not be required for a long time. But in the case when repair is necessary, it is made quite simply, observing the technology of carrying out
Repairing self-leveling floors at a cost can be slightly inferior to laying from scratch. Therefore, it is better to immediately take a responsible attitude to the selection of performers, since bringing to mind the results of their work can turn out to be a very, very expensive task.
Despite the fact that floor repair is not a frequent need, since such coatings have a long service life, sometimes it is still necessary. The reason for this may be time, that is, the self-leveling floor has already served for at least 15-20 years, and in some of its places delaminations or cracks began to appear. The second reason that the repair of self-leveling floors was required may be violations during the initial laying of the floor, that is, an improperly prepared base, the use of quality materials, their incorrect styling, etc.
If you have any problems with the self-leveling floor, please contact our company - the self-leveling coating will be restored in a short time according to the technology of laying the self-leveling floor and taking into account all the nuances that arose during the repair. Repair of self-leveling floors may take more or less time, depending on the scope of the proposed work, the presence of a pattern on the floor (that is, it is supposed to restore the pattern, adjust elements, etc.), the complexity of the damage and the urgency of the repair.
The same applies to the cost of the work. When ordering a self-leveling floor repair, you should take into account that only professionals, whose services we bring to your attention, will be able to do this work correctly. Ordering such repairs in artisanal and amateur workshops, as a rule, does not guarantee a result.
Restoration options for self-leveling floors depend on the nature of the defects. Worth a closer look possible breakdowns, the causes of defects and ways to eliminate them with your own hands or by calling a professional team.
Defects, causes of their occurrence, method of repair
Peeling of the polymer coating from the base
Peeling of the top layer of the coating together with the primer from the base surface is one of the most common types of defects. The reason is an obvious marriage in the production of work or the technology for pouring the coating was not followed, for example:
- the process of grinding / cleaning the surface was poorly performed to remove a weak layer of concrete, cement laitance, etc.;
- the procedure for dedusting the surface before priming was not carried out;
- the priming process was carried out on a wet, dirty base.
Do-it-yourself renewal option: dismantle the coating, clean and degrease the surface, pour in a new composition in strict accordance with the technological requirements. Cost when calling professionals from $15 per m².
Peeling of the coating from the ground without a ground layer
The reason is technological violations of the flooring process, for example:
- drying of the primer layer (before applying subsequent components) was more than 48 hours;
- pouring was carried out on a dirty primer layer (dust, water, dirt);
- the dew point has not been removed prior to coating the primer.
The repair technology is simple and with some skill, you can do it yourself: the surface needs to be degreased, cleaned. And after that, you can apply a polymer or self-leveling floor, following the recommendations established by the manufacturer. The cost of professional services is from $10 per m².
Elimination of cracks in the coating, exfoliated with a concrete layer of the screed
The reason is the low strength of the screed and a strong mechanical effect. Under such loads, a layer with high strength characteristics detaches from a weaker concrete base, forming cracks.
DIY repair options:
- dismantling of the polymer layer and impregnation of the top layer of the screed for maximum hardening;
- cutting down the concrete base on the cracked area and restoring it with repair compounds (sold in stores).
After that, the polymer coating is poured. When cracks appear over the entire area, it is necessary not to repair the floor with your own hands, but to call the masters to make a new screed with higher strength characteristics. Service price from $20 per m².
Wear of the polymer coating
The reason is the large load on the sites. It is formed in the places of baggage transportation, the passage of transport carts, high traffic, and so on. Repair option - dismantling the old layer and pouring a new composition. Service price from $15 per m².
Loss of aesthetic qualities of the floor
The reason is the abrasion of the polymer layer from intense and prolonged loads. Do-it-yourself repair technology is simple - apply new polymers, after cleaning the old ones.
Chips, potholes
The reason is the mechanical impact of blunt or sharp heavy objects. Often whole fragments of the concrete base are chipped along with the polymer. Repairing defects with your own hands is possible, but difficult: cleaning, priming, puttying, coating. Professional service from $15-20 per m².
cracks
The appearance of cracks on the surface of the self-leveling floor, says that the reason is a concrete screed. The concrete base "weakened" and, for one reason or another, lost its strength qualities. The occurrence of cracks on the self-leveling floor as such is impossible! The composition is extremely mobile and flexible to crack. With small forms of defects, they can be primed, pre-expanded, puttied and painted over.
Important! If there are a lot of cracks, the technology of updating and repairing the self-leveling coating is useless. Call for experts to complete dismantling top layer and replacement of the concrete base. Issue price from $25 per m².
Technological features of the restoration of self-leveling floors
Do-it-yourself self-leveling floor repair or a team of professionals includes the following stages of technology work:
- Filling new layers on old ones. It is necessary to pre-wash and dry the old surfaces, sand and degrease. And then pour a new layer, creating a solution according to the instructions provided by the manufacturer.
- Repair of areas damaged to concrete also requires cleaning, grinding and drying. The polymer layer is poured strictly according to the instructions, including the priming operation.
Remember that to repair cracks in an epoxy floor, only materials based on epoxy resins. You can watch all the stages of work on the video, but it’s still better to call professionals. The cost of the service may vary depending on the complexity and volume of work. But even at a cost of $25 per m², you will get a new beautiful floor in a short time, and not a bunch of problems, a waste of money and nerves.
Polymer defects floor coverings occur as a result of long-term use, Low quality grounds, violation of the installation technology, as well as due to the effects of an emergency nature. Repair of the self-leveling floor is carried out after establishing the nature of the damage and finding out the causes of their occurrence.
Consider the types of plastic deformations of epoxy and polyurethane coatings, grouping them by nature and localization
Destruction of the polymer layer
In practice, they usually face 6 types of problems localized in the polymer itself:
Substrate Issues
Poor quality concrete screed , violation of the technology of installation of self-leveling polymeric floors, as well as unforeseen exposure to moisture, lead to the following consequences:
Results of emergency actions
Drops of heavy, pointed metal objects can cause chips and gouges in the floor, breaking the integrity of the concrete base. Pouring aggressive chemicals onto polymers with insufficient chemical resistance leads to the destruction of the coating to the full depth, to the concrete screed.
Defect Analysis
In cases where the nature of the damage does not indicate a low quality of the substrate, it is sufficient to determine the boundaries of the proposed repair using trial removal of the coating. In several places, it is necessary to measure the moisture content of the concrete screed to determine the complete terms of reference for upcoming work.
When analyzing the reasons for the peeling of the polymer layer, one should use not only a moisture meter, but also a hardness meter, as well as a building thermal imager. Only this device guarantees the detection of hidden sources of moisture in concrete.
Polymer coating repair technology
Depending on the type of defects, the repair of self-leveling floors includes surface treatment of the polymer layer, its removal, or dismantling along with a part of the concrete screed.
Cosmetic restoration
You can remove scratches visible to the eye and restore the original gloss of the epoxy coating by polishing. The operation is carried out by a rotary polishing machine with felt wheels, on which a special emulsion is applied.
Restoration of polyurethane floors is carried out by applying a protective varnish.
Any surface treatment is preceded by thorough cleaning, dedusting and degreasing.
Repair with removal of the polymer layer
In some cases, it is sufficient to remove only the upper layer of the polymer by grinding with diamond wheels. This is done when a coating with sagging, bubbles, surface discoloration is to be renovated. A new finish layer is poured onto the sanded surface. If the area of defects to be corrected is small, it is possible to do without an industrial rotary installation. For local grinding, a conventional hand-held angle grinder is used.
Repair of cracks and delaminations involves the complete removal of the polymer coating. When the quality concrete substrate does not cause complaints, but they are going to remove the old fill over the entire area of \u200b\u200bthe room, the sequence of actions looks like this:
- Where the coating has poor adhesion, scraper-type punch nozzles are used for removal.
- In areas with preserved adhesion, chisel-type nozzles and grinders are used.
- The exposed surface of the concrete screed is sanded.
- A sequence of actions is performed that corresponds to the polymer floor installation technology: dedusting, degreasing, priming, applying the first layer, etc.
If the coating is removed in a limited area, then the perimeter is first determined repair work(it is made in the form of a rectangle). The pavement is then cut through to the concrete along this perimeter. Further work is carried out, as with the complete removal of the floor. The only difference is that the joints with the old coating are sanded and treated with special mastic.
What are the selection criteria: completely remove the coating or carry out local repair?
If decorative properties are important (for example, in offices and shopping malls), then local repair is appropriate even with satisfactory general condition surfaces. The decision to completely replace the polymer floor (regardless of the type of object) is made, as a rule, if more than 30% of the area of the self-leveling coating is damaged.
When replacing the coating locally, materials of the same type that have already been applied should be used. The exception is redecorating using methyl methacrylate mixtures. They work well in contact with other materials. The advantages of methyl methacrylates are the speed of work, the disadvantages are the low abrasive resistance.
Repairs affecting the concrete base
If the peeling of the polymer layers occurs due to the poor quality of the concrete substrate and the poor condition of the waterproofing, then it is impossible to do without altering the screed.
If, with a satisfactory quality of concrete, cracks in the screed are detected, the substrate should be restored. The traditional restoration technology consists in jointing cracks to the required depth, followed by dust removal, priming and filling with a polymeric repair compound.
Recently, an alternative technology called injection has begun to develop. First, the polymer layer is removed to completely expose the crack. Then, at an angle of 45 °, holes are drilled in the concrete towards the crack along its entire length with a step of 30-40 cm. Special fittings - packers are hermetically inserted into the holes. An injection pump is connected to the packers and a waterproofing compound is injected until it exits the fracture.
All repair actions after crack filling are similar to those described in the previous subsection.
Summary
Do not delay with the start of the repair. The price of delay is that instead of a cosmetic or local renovation, you will have to completely change polymer coating.
Defects such as delamination or cracks tend to rapidly increase in size. But one should especially hurry in case of emergency chemical destruction of polymers. So that the reaction does not continue in the thickness of the material, it is necessary to limit the affected area and completely remove the polymer layer from it.
In what cases does it make sense to save on calling specialists and do-it-yourself repairs? The decision to carry out renovation on your own is economically justified when the proposed work is limited in area and does not require the rental of expensive equipment. For example, having carefully studied the technology of working with repair compounds and armed with a cutter, puncher, scrapers and a conventional spatula, it is possible to replace the coating with small areas. But this only makes sense if necessary materials available for sale in exactly the quantity you need.
If it comes to artificial environmentally friendly coatings, then first of all they call self-leveling floors. In addition, it is an aesthetic and prestigious floor design solution in a residential apartment. They are highly durable and completely waterproof. When using quality polymer materials The need to repair self-leveling floors is extremely rare.
Polymer floors have a high margin of safety, which allows them to withstand exposure well. external loads while remaining tight and flexible. All of the above features make it possible to operate self-leveling floor coverings for 15 to 20 years, but a long service life becomes possible only if all technological processes during their manufacture and installation.
Compared to other types of coatings, they have a number of significant advantages.
Polymer floors:
- resistant to mechanical stress and abrasion;
- maintain integrity even after an object weighing up to 10 kg falls to the floor from a height of up to one meter;
- keep the base, say concrete, from destruction;
- can be dust resistant, antistatic, hygienic, chemical resistant and others.
The remarkable characteristics of industrial floors, such as resistance to temperature extremes, acids and other chemicals, etc., make them especially popular.
The ability to perform them in different textures and colors of the coating allows you to choose a self-leveling floor for the interior design of a particular room.
However, even with the most favorable conditions sometimes it is necessary to carry out repairs of polymer floors, because. over time, they become dirty, due to shrinkage, cracks appear on their surface, roughness, partial peeling, the formation of small grains on the floor surface, etc. can occur. In most cases, the repair of apartments, the self-leveling floors of which need preventive maintenance, can be carried out in a short time with the help of polymer building materials.
On a note
However, you should be aware that during repair work, only mixtures compatible with the repaired flooring should be used. Among other things, the repair compound must ensure good adhesion to the subfloor.
When Repair Is Necessary
The need to perform such work usually arises in certain cases:
The most common defects and how to fix them
Self-leveling floors are an improved version of the standard concrete screed. Despite its good parameters, it has a number of disadvantages - the likelihood of cracks and potholes, a rough surface, and hygroscopicity. The logical step was to add an outer protective layer that would compensate for all the shortcomings. It was decided to use polymer mixtures as the main material for manufacturing. As well as being durable, they are durable and easy to install.
The general scheme of the self-leveling floor is a sequential application of layers of concrete, primer and polymer fill.
The main advantages of this technology are the reduced weight of the flooring, reliability and the ability to improve the aesthetic appearance of the flooring. To implement the latter, a special canvas with a selected pattern is installed on the dried primer layer, and then a transparent polymer is poured. The result is an original design coating.
But even in this solid structure, defects can appear, the elimination of which must be carried out promptly. The main types of integrity violations have the following external signs:
- The formation of cracks on the floor surface and its partial peeling. These defects can occur if the polymer mixture was applied in a thick layer, or the installation was carried out on a contaminated base. To eliminate these shortcomings, the floor covering in problem areas is removed, the concrete base is carefully cleaned, after which a new composition is poured.
- The appearance of rough patches. This defect is usually the result of excessive viscosity of the polymer composition. To eliminate it, it is necessary to reduce the viscosity and increase its layer.
- Flaking. This situation is possible if the installation of the self-leveling floor was carried out on a damp or contaminated base. Such a disadvantage is quite difficult to eliminate, because. problem areas must be removed to the base of the rough surface, which, in turn, is carefully prepared for applying a new layer.
- The appearance of grains. This defect appears when dirty tools are used during the installation process. Best of all, the grains are removed with a grinding wheel, after which a fresh layer is applied to the treated floor surface.
- Damage, minor scratches. These defects are fairly easy to fix. To do this, the entire surface of the repaired floor should be sanded, cleaned of dust and all kinds of contaminants and dried well. After the preparatory work a new layer of polymer composition is applied to the cleaned surface. It should not be forgotten that the humidity level in the room in which the work is to be performed should not be higher than 60%. If for some reason the installation technology is not followed, then the bulk coating may begin to peel off. And quite deep cracks can form on its surface. The consequence of the manifestation of such flaws can be a complete replacement of the floors, which is a rather time-consuming and costly task.
What to do if defects are found
In general terms, the repair process can be divided into the following stages:
- weak spots on the self-leveling floor, that is, where it does not fit snugly, are removed;
- carefully, with the help of milling and grinding, the exposed base is leveled;
- the detected cracks are expanded, then a specially prepared repair mixture is poured into the resulting holes;
- the surface is cleaned of the resulting dirt and dust with an industrial vacuum cleaner;
- apply a new coating.
To minimize the cost of removing the above defects, certain technological schemes should be applied.
Delamination
Professional repair of polymer floors begins with a search for the causes of a violation of the uniformity of the surface. Often they are violations of the coating installation technology. For example, before applying the primer, the concrete layer was not cleaned, during which the cement "milk" is removed and the screed is loosened. The presence of dust and dirt between the coatings is also a cause of delamination.
The external manifestations of these factors are the swelling of the polymer coating and its small shifts under directed external action.
To eliminate it, do the following:
- Analysis of the area of damage. Accurate determination of its boundaries will reduce the complexity of the work and the consumption of materials.
- Remove the polymer layer, check the condition of the primer. If it is satisfactory, then you can start pouring. Otherwise, the middle layer is also dismantled.
- Before starting work, the surface is degreased, the solution is mixed according to the manufacturer's recommendations.
- After pouring, air voids are removed using a special spiked roller. The new layer is leveled and, after hardening, polished.
The last point is more important for maintaining the appearance of integrity. If these actions are not taken, then the place of replacement of the polymer flooring will be clearly visible.
This method is often used if renovation of apartments is required. Self-leveling floors, even in new houses, do not always meet the requirements for the quality of their manufacture.
The polymer coating can peel off from the base, literally in pieces, due to poor cleaning of the base from moisture, dust, fatty deposits of organic and mineral origin, or any other contaminant. This defect is considered one of the most difficult, because if total area damaged areas will be too large, a complete replacement of the coating will be required. It is more convenient to do this by performing apartment renovations. Self-leveling floors harden within about a week, and this time can be used productively for another cycle of repair work.
Situations when complex delamination occurs are typical for insufficiently hard concrete mortar at the base. If the curing period has not been met, then excess moisture remains inside. The polymer layer has the properties of hygroscopicity - the absorption of water from the outside. Its outer part was protected during the installation process. With the help of leveling and processing, the surface stress forms a dense patch.
Since water vapor, leaving the concrete base, is concentrated in the primer, over time it delamination occurs. The best way to eliminate this defect is to install a new floor in the area of damage. This procedure is fully consistent with the installation rules with a few exceptions.
At the junctions with intact, its edges are treated with mastic, which will ensure the adhesion of the new layer to the rest of the floor structure.
The appearance of cracks and holes
Most often, potholes and cracks occur in self-leveling floors offices and industrial premises. During operation, load standards are neglected, as a result of which the coating not only loses appearance, but also deformed.
The nature of the damage affects only the top polymer layer and, in very rare cases, the primer. If this problem occurs, the offices should be repaired immediately. Self-leveling floors are a connected system of several materials. It is enough to break the integrity in one place, as the reaction will acquire an avalanche-like character. With use, damage will increase, affecting not only the top deck, but also the internal components.
The best way to eliminate the defect is to promptly pour a new solution on the damaged area. To make this work, you need to follow these steps:
- Inspection of the pothole to determine its actual size. Sometimes there are hidden cracks. If they are not handled properly, then a similar problem may occur again.
- By using grinder the edges of the pothole are aligned and the cracks expand to a width of 1 cm. This is necessary for applying the bonding composition.
- Surface treatment with mastic, which is intended for self-leveling floors.
- Prepare polymer solution according to manufacturer's instructions. For sealing, it is optimal to use special repair compounds.
- Filling the mixture and leveling the surface. If necessary, after hardening, the contours can be grouted.
Upon completion of the work, mechanical impacts on the area of the restored flooring are undesirable for about 2-3 days.
Restoration
Over time, the polymer surface may become covered with small cracks or lose its proper appearance.
If their depth is less than the polymer layer, then a small cosmetic repair can be made. But first it is necessary to check the dimensions of each defect - if they have significant dimensions, then first overhaul floor according to the technology described above.
To improve the strength characteristics of the repair coating and better adhesion to the main surface, the floor surface is specially deformed - strobed. Next, a new polymer mixture is poured onto this base. The technology of its preparation and installation completely repeats the process of primary laying of the floor. Upon completion, a certain time is required for solidification. It is determined according to the instructions.
We also note such defects as:
- Cracks and peeling. Peeling of the film, cracks on the surface of the coating most often
- too thick polymer layer;
- a sharp decrease in the adhesion of the material to the base, when the latter is not sufficiently cleaned.
In this case, the damaged area is removed, ground down to the base, the concrete base is cleaned and re-coated with the same polymer as before.
- Uneven surface. Due to the too high viscosity of the composition, a roughness resembling an orange peel is formed on the floor surface. To correct the defect, the viscosity of the material is reduced and its layer is supplemented.
- Foreign inclusions and grains. This is a defect from dirty and uncleaned tools - foreign inclusions are mixed with the polymer. The only way to get rid of them is to smooth the surface with a grinding wheel, then apply a new layer.
- Delamination and turbidity. If the composition turned out to be too liquid or poorly mixed, as well as in the case of an incorrect ratio of components, the surface delamination occurs and the floor turns white. One more finishing layer can improve its condition.
This once again shows how important it is to comply with the technology of self-leveling floors.
Violations of the technology, in particular, insufficient ventilation, low surface temperature (2-4°C), violation of the ratio of components are also evidenced by an overly long curing process of polymer floors.
Repair of industrial floors made of polymers
Industrial floors are considered one of the necessary conditions for the normal functioning of shops, public institutions, warehouses, industrial facilities, etc.
In appearance, they resemble linoleum without any joints, but they are distinguished by increased strength. Despite the apparent simplicity of this type of industrial floors, their installation requires special knowledge and strict adherence to the pouring technology. Any violations made can cause various defects in the coating.
- An important role is played proper preparation concrete base, since any of its defects, such as potholes and cracks, are repeated on the finish coat. To eliminate, say, a crack, it is necessary to joint it to the entire depth of the base, prime it and fill it with a repair compound and fill it with a polymer compound.
- Lack of primer or insufficient amount of primer leads to the formation of craters and small through holes.
- Due to a violation of the technology for preparing the composition for pouring small bubbles may appear on the surface of the industrial floor, it may turn out to be inhomogeneous, sticky even after the end of the polymerization process.
- Compliance with the laying technology ensures not only the stability and durability of self-leveling industrial floors, but also helps, for example, to even out small irregularities in the concrete base.

BY TYPE
Bulk floor in the apartment
Among floor coverings, used in the apartment, self-leveling floors are popular today, overshadowing even the laminate and tiles that were previously in demand. In their favor are such facts as:
- abrasive resistance;
- diversity design solutions apartments;
- long service life.
- epoxy flooring;
- polyurethane flooring;
- cement-acrylic;
- methyl methacrylate.
Epoxy resins are highly decorative. Floors can be matte or glossy, three-dimensional or backlit. The coating is resistant to moisture and household chemicals. An attractive price combined with high wear resistance has made this type of self-leveling floor one of the most popular among customers. Polyurethane floors, as well as epoxy floors, are durable, not afraid of moisture and chemicals, and resistant to abrasion. Cement-acrylic self-leveling floors are durable, non-slip surface, resistant to moisture. Most often used in the bathroom, toilet or kitchen. Methyl methacrylate self-leveling floor has short term hardening layer, ready for use in 2-3 hours.
Benefits of using a self-leveling floor in an apartment
As a floor covering apartments self-leveling floor is used not by chance. Among its main advantages, customers and specialists distinguish:
- durability of the material (at least 15 years, with a thick layer - more than 30 years);
- versatility (can be used as an independent coating (in combination with the "warm floor" system), as a base for a laminate or carpet);
- tightness (moisture does not penetrate into its structure, bacteria dangerous to health do not start);
- the presence of fungicidal additives;
- strength (may be damaged by strong point mechanical impact);
- wide selection colors improving design.
Disadvantages of bulk coating
At in large numbers pluses self-leveling floors at home are not without minuses:- long and laborious preparation of the base;
- it is recommended to use with a water system "warm floor";
- high cost (taking into account the materials used);
- strict adherence to technology.
Filling the self-leveling floor in the apartment
The technology of filling the self-leveling floor in the house verified by experts the smallest details. A slight deviation from the technology will lead to the rapid arrival of the coating in emergency state. The result of violations is the repair of self-leveling floors, which is only slightly inferior in price to the original filling. The work should be carried out by professionals, but it is better for the owner of the dwelling to know their order in order to be able to control it.
Self-leveling floors are poured onto a cement or concrete screed. It is necessary to carry out well the dismantling of old coatings, leveling and repair work old screed. Next, the floor screed is preliminarily, qualitatively cleaned of all types of contaminants, primarily oil or paint stains. From this, the quality of styling depends quite strongly. To improve the adhesion of the polymer mixture to the screed, the latter is covered with a primer layer. Beacons are installed on the floor. Then the composition of the self-leveling floor is distributed from the far corner of the wall to the exit from the room, its amount is calculated in advance, even when preparations are underway.
It is important to use quality materials correctly, observe technology and time frames in work. To create a flat surface, so that it is free of defects, it is recommended to install beacons on the very surface of the floor and at the base of the walls. Masters should not allow the formation of air bubbles on the surface. After solidification, they lead to serious defects, not to mention the fact that the expensive composition will be damaged.
Repair of polymer self-leveling floors
Loss of bulk polymer coating its performance may occur as a result of long-term operation or due to a violation of the filling technology. In the first case, due to high strength and long service life, the surface simply loses its attractive appearance. To update it, you just need to sand the coating and apply a new thin polymer layer. This work is done quickly and is relatively inexpensive.
More difficult to work if the resulting defects are associated with a violation of the pouring technology. When performing repairs, the technology that is necessary when pouring the coating in a residential area is strictly observed. The materials that are used in this case must match those that were originally used to improve adhesion.
Where to begin
Repair of self-leveling polymer coatings in apartments should begin with a thorough check to find out:- how much floor area is damaged;
- what caused the defect;
- how many layers will need to be replaced during the repair.
Types of defects
The most common damage to poured concrete and epoxy floors caused by improper pouring:- cracks;
- swelling and tubercles;
- color changes (whitening);
- delamination.
Stages of self-leveling floors repair
Restoration of self-leveling flooring in residential premises is carried out by the specialists of Politek System LLC as follows:- Examine the floor in the room and identify defects.
- In case of swelling, cracks, discoloration, the upper polymer layer is dismantled with a perforator (so that there are no delaminations), the surface is prepared, a primer is applied, and a new polymer layer is poured last.
- If cracks are found, work is carried out in a similar manner. A feature of the restoration of the coating in case of cracks is the study of the depth of damage.
- It is necessary to dismantle all layers. Laying a new coating on a dismantled site is carried out in compliance with the technology for each level.
- Delamination is a defect that provides for the most complex repair, since not only the polymer coating can be separated, but also all layers, including the screed, to the base.
Repair of self-leveling polymer floors in case of peeling
If this type of defect is detected, an investigation is carried out, allowing you to determine which layers need to be restored. At the same stage, the area of damage is determined. Often it turns out that the areas located near the defect have the same problem. Soon they will need the same repairs. In this case, it is more expedient to remove the entire coating laid in violation of the technology, which led to the formation of problems.
Such repairs are not cheap pleasure, and for its implementation it is necessary to invite professionals with experience in pouring self-leveling floor coverings and carrying out repair work
