The beauty sewing master who has done polyurea beauty sewing knows that the difficulty of polyurea beauty seam construction is more difficult than epoxy beauty seam construction, and the requirements are higher.
The seams should be cleaned thoroughly
The depth of gap cleaning is not enough, the tile sidewall is not cleaned thoroughly or the dust in the gap is not clean, and the black edge, bulging and falling off of the seam are bound to happen.
The material should be beaten solidly
Polyurea seam has a small density and high elasticity, if the material is not full, the bottom gas is pushed upward, and it is very easy to have the problem of bulging in the seam. When beating, you can slow down the beating speed to ensure that the material is full and compact.
The seam should be pressed in time
The curing speed of polyurea seam is fast, and the operation time is about 25 minutes, so it needs to be pressed in time. It is recommended that 2 people cooperate with the construction at the same time, one dozen and one press, the effect is better.
Waxing in advance
Polyurea sewing agent is more viscous than ordinary sewing agent, if not waxed, the remaining material is difficult to clean in the later stage, and may also damage the tile, in order to protect the tile and facilitate the later shoveling of the remaining material, it is recommended that all types of tiles must be waxed in advance.
Special attention should be paid to the details in the construction of polyurea seams, and the quality of the construction effect of the seams is hidden in these details.
