Do not use without dilution! The high dry residue of undiluted primer-concentrate creates a smooth "slippery" film on the surface, on which paints are poorly applied, the surface is painted unevenly, with gaps.
The surface of a concrete structure is most susceptible to the effects of aggressive environments and wear. It cannot be made without pores, since there is excess water in the concrete. This is the main cause of shrinkage deformations and the formation of microcracks and pores. The durability of the structure can be significantly increased if the pores and cracks are filled with a crystalline structure chemically bonded to the walls of the pores and capillaries. The structures formed in the pores and microcracks of the treated concrete are similar to natural minerals, and the durability of these structures is comparable to the durability of natural minerals.
Before installing the self-leveling floor, clean the screed of all dirt, remove the weak top layer (dried "cement milk") from it and be sure to strengthen it with a special primer.
