Most often, PVA glue is used for small home repairs and less often when gluing wood in professional workshops.
Today, there are no analogues of chemical anchors, especially when it is necessary to attach a heavy element to a hollow base. Despite this, the material still has several disadvantages.
The cement-based finishing material, which includes various special chemical additives that make it strong, durable and wear-resistant, is called micro-concrete.
A mechanical anchor will not be able to cope with fastening into weak bases. These include hollow blocks and bricks with voids. But a chemical anchor is ideal for working on such bases.
Micro concrete is a thin–layer finishing material based on cement, which includes various fillers, such as polymers, ultrathin fillers, pigment and other additives.
