Synthesis of high molecular chemical products containing active groups in the main liquid, superfine silica titanium dioxide and sulfide through special processing agent for curing agent composed of two-component polymer waterproof coating material.
The product after mixing evenly coated on the wet concrete surface according to certain proportion, through the chemical reaction after several hours to get a layer of rubber like waterproof layer, firmly pasted on the surface of concrete.
This product is a two-component curing type waterproof coating, coating, rubber at room temperature to form the shape of waterproof coating, adhesion to the substrate is not happen without foaming coating delamination, and loss of strength, extensibility and flexibility, and solves the problem of water proof construction in wet concrete surface.
Main uses: D
1, all kinds of underground buildings and waterproof, including underground passages and tunnels, garage, pool etc..
2, all kinds of wet state of the concrete roof, gutters, awning, flower beds, etc..
The construction method:
1, the base surface should be firm, not sand. Before construction should clean the surface dirt, dust, mud, oil; mortar eradicate protruding, concave to polymer mortar batch embed uneven.
Ingredients: 2, B to stir well, then the coating according to group A: B =1:2 (weight ratio) mixed with a wooden stick or simple mechanical mixture.
3, smear and brushing with rubber scraper or paint brush, with good batch scrape or brush to the grassroots, scraping or brushing should be as uniform as possible. The film thickness formed as consistent as possible.
4, the construction amount, about 3-3.5m2. 2-3 batch scrape or brush, interval time of 24 hours or so, not a finished, lest cause uneven flow coating. The film thickness is 1.5-2mm, in order to ensure the quality of waterproof engineering.
Waterproof layer 5, underground waterproof engineering, as far as possible should be done to meet the water how to fry, avoid waterproof layer caused by large underground water is separated from the base pressure.
6, each 72 hours after construction should avoid soaking in water, after once brushing, application of cloth to wipe before once coating the surface of the water.
Matters needing attention:
1, the long-term immersion in water or water rain must base on drained and dried after 24 hours before construction.
2, concrete must meet the maintenance period. In the wet concrete grassroots besmear after three days should be to avoid strong direct sunlight.
3, in the vertical construction, in order to prevent the coating flow, mixing time can be appropriately extended (usually 10min)
4, construction of underground water, generally do in the face of the water how to fry, to avoid bigger groundwater pressure causing the waterproof layer peeling. |
