Although many homes and businesses find concrete floors to be long-lasting and sturdy, they are not impervious to damage. Cracks, potholes, and other flaws can appear over time and affect both the appearance and functionality of your floor. By learning how to fix these problems correctly, you can prolong the life of your concrete surface and save time and money.
Concrete floor cracks are frequent and can be caused by a number of things, such as settling, large loads, or variations in temperature. It is essential to treat these cracks as soon as possible to stop further damage. Simple techniques exist for fixing cracks so that your floor stays sturdy and level.
Another crucial component of maintaining concrete floors is impregnation screeds. By filling pores and penetrating the surface, these treatments strengthen the barrier’s resistance to chemicals, water, and wear. You can extend the life and durability of your concrete floors by using impregnation screeds, which also make them easier to clean and maintain.
Potholes are more than just an annoyance; if ignored, they can endanger public safety and cause more serious damage. Potholes should be repaired as soon as possible by clearing the damaged area, adding the necessary materials, and making sure the surface is level and smooth. This procedure stops further issues and restores the integrity of your floor.
You can maintain the best possible condition for your surfaces and save money by learning the fundamentals of concrete floor repair. In order to maintain the aesthetic appeal and practicality of your concrete floors, minor maintenance is necessary, whether it is for pothole repairs, impregnation screed application, or crack repair.

Thixotropy and rheology
It’s worth learning a few key ideas before looking at floor screed repair techniques. Thixotropy is one of them; it is a medium’s capacity to reduce viscosity when subjected to continuous influence. Common construction bitumen is a remarkable illustration of a thixotropic material; upon application of pressure, a depression emerges on the surface.
Here, we should also discuss rheology, which is superfluidity. a phenomenon that everyone experiences in daily life, not just physicists. Sunflower oil serves as an illustration of this characteristic; it is not nearly as fluid as liquid helium, for instance.
Thixotropy and rheology are closely related in building conditions. Understanding these ideas is crucial when fixing concrete screeds. Rheology fills in all the smallest irregularities during the repair process, and thixotropy allows the old and new concrete mass to interact for optimal coating strength.
There are numerous thixotropic-rheological mixtures available in the contemporary construction materials market that are intended to fix flaws in concrete floors. They are made of polyurethane and epoxy resin, but you can make a cheap, thixotropic composition with your hands to repair a concrete floor in a home or apartment (assuming stable conditions are present and no heavy loads).
- PVA glue or bustilate must be diluted with water in a ratio of 1:3/5.
- Mix a cement-sand mixture on a diluted glue solution, taking 1 part cement and 3 parts sand. For large volumes of work, you can buy ready-made PVA putty (this is the same diluted glue, but in a large container of 5 liters).
- Seal the floor covering, let the floor dry well – and you can use it.
Deep cracks should not be repaired with PVA-based suspension; instead, use a repair compound and a reputable thixotropic primer made for concrete work. Apartment floors work well with budget compositions; for industrial floors, it’s best to use the best, most long-lasting materials.
Mixer and rule
Mixing is an essential component of nearly all compositions, regardless of the method used to repair cracks in concrete floors. Purchased ones are mixed with water, and homemade ones are combined with PVA suspension. With so little water added, the viscous mixture does not lend itself well to manual action, making it nearly impossible to mix the solution by hand. You will have to mix for a very long time, during which time there is a good chance that the solution will start to set.
Use an electric drill or hammer drill with a special mixer attachment, set to minimum speed, to mix a small amount of the composition for repair. Stores carry a wide variety of mixers, but you can also make your own using a straight rod that is 50 centimeters in length and has a cross-section of 8 to 10 millimeters, with one end bent into a ring.
Before filling the defect, the solution needs to be mixed for three to five minutes. If mixing in a bucket, move the tool in a circular motion; if in a trough, move it in a zigzag transverse motion. It is best to have a container of water close by because the mixer needs to be completely rinsed right away after mixing by dipping it in water and running it on high speed.
When mixing with a hammer drill, the room and master bedroom will be instantly covered in a thin layer of concrete, so avoid turning on the impact mechanism.
You might also require a rule—a specialized instrument about one meter wide that works similarly to a spatula—in order to fix the floor. Purchasing a factory rule is preferable in order to prevent the concrete from "eating" the tool’s rubbing portion.
Types of concrete floor repair
There are several situations where restoring a concrete floor may be necessary. Numerous objective and negative factors can impact the coating; as a result, different methods are employed to eliminate defects that present differently.
- Elimination of various defects – potholes, bulges, different slices from formwork, minor cracks on the surface.
- Sealing of serious cracks spread through the monolith.
- Implementation of the overhaul of the floor screed until the finish coating, polishing concrete monolith, installation of a warm floor with waterproofing/insulation/insulation.
- High -quality dusting.
Every one of the listed repair types entails the application of a particular technology. The hardest and priciest is surface repair for a clean floor. This time, the overhaul is completed.
Regardless of the technology utilized (apart from diluting), the floor needs to be left in place for at least 20 days after it is finished, with intermittent water spraying or damp cloth wiping.
Preparation of the premises
The room and the coating itself need to be properly prepared before repairing a concrete screed. First, the room is made completely empty by removing all furniture, equipment, and other interior items. If a floor covering is present on the screed, it needs to be taken apart.
Next, clear away any dust and debris, giving any damaged areas extra attention as this is where the majority of the concrete fragments, peeling components, etc. tend to gather.d. A metal brush is used to remove layers of outdated primer, different paints, varnishes, and chipping concrete sections.
To improve adhesion between the old and new concrete, notches are made on the damaged area after everything has been thoroughly cleaned. Using a broom, any chips or dust that arise during the process are carefully swept up. If you have a construction vacuum cleaner, it is preferable to use it. After that, a primer or degreasing impregnation is applied to the surface with caution.
Although it may seem difficult, repairing concrete floors is completely doable with the appropriate strategy. Although surface wear, potholes, and cracks are common problems, your concrete floor may still be intact despite them. You can prolong the life and usefulness of your flooring by being aware of the various techniques and materials that are available.
The first step in treating concrete floor cracks is to completely clean the area and remove any debris. Cracks can be successfully sealed off and additional damage can be avoided by using an appropriate filler or sealant. To guarantee a long-lasting repair, it is essential to select the appropriate product based on the size and type of crack.
Using impregnation screeds can significantly increase the longevity of your concrete floors. By penetrating the surface, these treatments offer more defense against moisture, chemicals, and wear. By using an impregnation screed, you can strengthen the floor’s overall resilience in addition to fixing minor surface damage.
Although they take a little more work, potholes can be successfully fixed with the right tools and methods. First, make sure the pothole is dry and clean. After filling it with a patching-specific concrete mix, firmly compact it to remove any air pockets. For a robust, long-lasting repair, level the surface and give it enough time to cure.
Concrete floor maintenance and repair don’t have to be difficult tasks. You can successfully handle these common problems if you have the necessary tools and some basic knowledge. Your concrete floors will stay safe and functional for many years if you provide them with routine maintenance and prompt repairs.
