Repair and treatment of cracks - interior walls
Hello everyone,
Cracks in the interior walls are no stranger to us, you don't need to be a genius to know when the crack is dangerous and requires an engineer's visit, usually these are cracks that start at 3 mm or more.
We can all repair cracks, we just have to do it properly with the right materials and every year new materials are developed that make our job easier.
Most cracks are an aesthetic defect and correct repair will keep the crack hidden for a long time.
The main part of the work is opening the cracks by expanding the crack to 4-6 millimeters (in the upper part only) and 10 mm deep. Clean the groove from particles, apply a binder and inject a flexible "polymer" into the crack. This allows the groove to expand and contract according to temperature changes without a visible crack forming. Beyond that, flexible paint can help a lot and give the wall a smooth appearance for a longer time.
Successfully.
