Several methods of waterproof and plugging

1, plugging: use a chisel or percussion drill to make a hole with a depth of 4 ~ 5 cm and a diameter of 2 ~ 3 cm at the water seepage site. After cleaning, add water (ash: water = 1:0) to the r- 1 material. 3) Stir well and knead into dough (the size of the dough is similar to that of the hole). When the palm feels hot, quickly put the dough into the hole and hold it for a few minutes with the palm. When the palm feels stiff, loosen the palm and flatten it with a board. /kloc-wet curing after 0/5 minutes;

2. Plastering: After the base surface is cleaned and fully wetted, r- 1 material is added with water (ash: water = 1:0. 4) Stir evenly (raw materials or particles are not allowed) to be putty-like, and quickly coat 1 layer (thickness 1mm) with a trowel or scraper. After the coating hardens, spray water for wet curing, and then coat the second layer (thickness 1mm), and make the coating compact with a little force when feeding. If there is still local water seepage or wet stains, just add another layer at the water seepage or wet stains until it is waterproof and wet.
