solving the cracking problem of inorganic grinding stones
in our daily life, we have seen the cracks of terrazzo on the ground because in many new projects, the surface construction will be carried out before the concrete ground is completely dry due to the construction period, which leads to the water in the concrete not completely evaporated. in this case, the surface of the terrazzo will certainly increase the risk of cracking.
therefore, reducing excessive moisture in the concrete layer and preventing water transfer to the surface is quite important. if the construction period allows, we suggest that the surface of the concrete should be completely dried before the construction of the grinding stone layer. if not allowed, it is recommended to use anti cracking mortar specifically for grinding stones.
this grinding stone special crack resistant mortar has high adhesion, crack resistance, breathability, frost resistance, water resistance, and odorlessness, making it easy and fast to construct and harden in humid environments
according to the requirements of different inorganic grinding stone surface bases, the mortar at the interface can be adjusted to self flow and batch scraping types, with a thickness of generally 30mm-50mm, to better protect the surface of the inorganic grinding stone
if crack resistant mortar is used on the surface of concrete, it should be combined with pe film and steel wire mesh to gradually form a moisture reducing and crack resistant effect, forming a tight protective layer on the concrete surface, greatly reducing the transfer of water through the surface
