In order to make hard concrete flooring, after a few hours, concrete hardening powder should be poured on the concrete to a thickness of approximately three to four millimeters and a propeller trowel should be applied on it to penetrate into the concrete. After drying, the surface concrete is much harder than concrete. created . Therefore, due to its small thickness, it is very important and its formulation with hard metal and mineral elements and its compatibility with concrete is very important and determines the life, durability and hardness of concrete coating and therefore surface hardening powder The concrete of Farapooyesh Company is the result of a lot of research and study in this regard and has the highest durable qualities
