Construction precautions for concrete interface agents

1. The construction environment should be dry, the relative humidity should be 70% smaller, and the ventilation should be good. The temperature of the base surface and the environment should not be lower than +5℃.

2, the base surface preparation: the base surface should be clean, not loose, no dust, grease, moss, carpet glue, etc. should be removed, loose and cracked parts should be removed and repaired in advance.

3, maintenance and finished product protection: ventilation must be strengthened, natural maintenance can be, until the slurry is dry (the surface is grayish black) and confirmed that the base surface is completely closed before the subsequent process can be carried out.

4. Cleaning of the tool The solidified slurry is difficult to remove. After using the tool, it should be washed off with water as soon as possible.
