Waterproof plugging construction plan

1. Primary treatment:
Cleaning treatment: Remove surface waste materials such as floating soil, yellow sand, stones, etc., and keep the site clean, stable, flat and smooth, free of dust and oil.

Strengthening treatment: All parts and joints that are prone to leakage, such as wall, wall, pipe root, gutter, cornice, eaves, expansion joint, dormer window, yin and yang corners, etc. must be used first Proportion of mixing, mixing, coating and spreading chemical fiber non-woven fabric for strengthening treatment, there should be no sanding, honeycomb pitted surface, sand holes, holes and cracks.
Roofing construction: The roofing under the waterproof layer should be carried out in accordance with relevant construction specifications.
2. Ingredients:
Pour the liquid into the mixing tank first, then pour the powder into the liquid, and stir thoroughly until there are no small particles agglomerated. During high temperature, a small amount of water can be added (control within 5% of the liquid weight). For larger projects, mechanical stirring must be used.
The paint color powder should be mixed with the liquid first and then mixed with the powder evenly. The prepared waterproof coating should be used up within 45 minutes and used as soon as it is prepared.
Traditional construction method of external wall waterproof plugging
If the building is leaking, it means that there is a problem with the treatment of the waterproof layer. There are hard ceramic tiles on the surface of the waterproof layer. The traditional method is to pry the outer tiles, dig out the waterproof layer, rebuild a new waterproof layer, and re-lay the tiles. . Among them, labor costs, material costs, and time spent are very large.
The latest method of external wall waterproof plugging
The traditional concept of waterproofing leaks is to patch up where the leaks are. The latest method of waterproofing leakage is to abandon this traditional concept. If the waterproof layer leaks, do a good job of waterproofing and leakproofing on the outside of the tile. As long as the surface of the tile is waterproofed, the waterproof effect is the same.
External wall waterproofing and leak repairing construction method: use a knife to remove the waterproof cement or solid glue between the tiles, use a dryer to dry the ground for a day, and then fill the gully with cement of the same color as the floor (the ground is white , Just fill with white cement, the floor is black, just fill with black cement, this is for the beautiful light of the room.) Then use a special CPC waterproofing agent to slowly pour into the cement, after 1-2 days, waterproof The agent and cement will be firmly adsorbed on the tiles, effectively forming a stable waterproof layer.
