Despite the high strength and sufficient durability of concrete, this material also has its drawbacks, which lead to gradual loss of source properties. First of all, we are talking about a concrete field that can be in a variety of conditions. At low temperatures, concrete loses its strength, and mechanical surface damage can lead to the formation of huge cracks. Concrete floor repair should be carried out only in cases where damage is no more than 40% of the entire surface. In other cases, it is best to carry out full-fledged construction work on the creation of a new concrete screed, having previously got rid of the outdated layer of material.
Main features of concrete damage
Often, concrete flashes are detected after removing the floor material. In the overwhelming number of cases, damage are small cracks, from which it is necessary to get rid of.
That surface that has no flooring is primarily exposed to various processes, as a result of which cracks appear and potholes.
Timely repair of the concrete surface will help save a lot of money. If you do not produce the necessary procedures on time, then not avoiding a full and expensive repair.
Concrete floor crack repair
As mentioned earlier, most often the concrete coating will get cracks. They can be practically inconspicuous, and in a few months they are possible the formation of large elevation.
The presence of cracks means that a lot of errors were made during the creation of a concrete screed. It is about violation of the technology of drying material, as well as the non-compliance with the special requirements for the solution, which is uniquely notified by the manufacturer of products.
To avoid expanding cracks, which will definitely increase in size, you need to immediately hold a number of building events.
With the help of the Bulgarian, you need to expand the crack, and also deepen it. In this case, it is important not to rearrange, so that new cracks subsequently appear. The deepening should be at least 20 mm. The edges of the extended crack must be cleaned, as they will definitely crumble.
Bulgarian is also useful for the creation of small sites, the location of which should be perpendicular to flaws.
Next, you need to qualitatively clean all the deepening of the concrete surface. After a small cleaning, it is necessary to arm the brush and put the primer directly deep into the cracks.
Each crack must be filled with a concrete mixture. Many experts in building business recommend pre-locally positioned metal brackets that will help for a long time to forget about any concrete sex flaws.
After the concrete gained strength, it is necessary to carry out the grinding of those places where there were cracks before. With the help of a building level, you need to check the surface to be perfectly smooth.
Repair of recesses and chosel on the concrete floor
Thighters in the concrete floor appear only in cases where the fill process occurred at all as technology requires. In this case, empties are formed inside the concrete layer, which in time begin to make themselves felt. If the concrete surface is located outdoor material, it will dry out or even fall to the depth of the screed. If you do not fix the problem immediately after it is detected, after a short period of time, the concrete tie will need to be replaced completely.
The process of repairing a concrete floor in this case is almost similar to the past method. You need to take a grinder and with it to cut rectangles around the perimeter and the whole depth of chosel. If small pieces of concrete remain, which can not be removed by the grinder, you can use chisel and hammer. It is advisable to make it so that the walls are chosen as smooth.
All rubbish, as in the past case, you must remove from the surface. It is best to use a vacuum cleaner for this. Next, primer is applied to the potholes. Immediately after its drying, the concrete composition is mixed and poured into the recess. The solution smoothes with a spatula. It is also necessary to check the gender of the floor using the construction level. Since potholes, most often, occupy a significant surface of the floor, to gain the strength of the concrete mixture will be within a few days.
Repair of dusty concrete floor
Dust on a concrete screed appears if the floor surface has no additional coating. At home, this occurs infrequently, but in the garage or entrance this is a common phenomenon. Over time, concrete begins to lose its original properties, and the surface of the screed is amenable to gradual abrasion. Every day, dust will be formed more and more. In the worst case, the appearance of chosel or small recesses is possible.
To cope with the problem, first you need to spend the surface of the floor and get rid of all garbage. Next, it will be necessary to polish the concrete tie. If dust is formed on the floor, then in the presence of small flaws do not doubt. Grinding can be carried out using sandpaper. It should be studied the entire surface of the floor to prevent even the slightest irregularities. After that, you need to spend the surface again.
All over the perimeter, the screed must be applied to the primer of deep penetration. The material will be saved for several hours. Now you need to apply a polymer dust-free polymer compatible composition, which can be found in most building stores. This composition must be applied in two layers to provide high-quality protection against dust. The primer is applied over the polymer, which should also have a defect penetration. Closer to the end of the repair process, a layer of construction glue is applied to the floor, and fiberglass rolls over it. After that, you can make the fill of the floor with one of the many polymeric materials. Similar mixtures are self-leveling, so no additional actions will be required.
