Reasons for knife marks on epoxy self-leveling floor:
A shovel knife, a tool for the construction of epoxy self-leveling floor finish, is like the flat knife we usually use, but one is rake-like serrated (as shown in the figure below), which can level the epoxy self-leveling surface paint layer while maintaining a certain thickness. When the trowel scratches over the coating, but the material can not rely on its own leveling to fill the scratches, after curing, there will be a series of trowel scratches.
There are two reasons for the problem of trowel marks. One is that the flooring paint materials are not used up within the prescribed time. In this process, the reaction between the main paint and the curing agent of the flooring paint has been going on. The paint solidifies step by step, and the viscidity gradually increases. Finally, the flooring paint can not be leveled. Another reason is that the amount of material used in design is too small. It's said that a skillful woman can't cook without rice. How can you make it flow with a little paint?
Solution to knife mark problem of epoxy self-leveling floor:
First of all, we should solve the problem of not using up the paint in the prescribed time from the root, that is, not too many ingredients at one time, 10-15 kg is good, no more, use up and match again. Second, don't be too cute, the amount of self-flow surface coating per square meter should be about 0.8-1 KG.
