Polyurethane Waterproof coating
Illustration
This kind of product is a newly developed high polymer waterproof material of the 90s, its main ingredient is polyurethane and other macromolecular substance. Its also the most perfect upgraded material among the domestic waterproof material, its performance index reaches the level of the like products of abroad.
Features
1. Excellent resistance to moisture, non-toxicity, non-harmful, safety construction.
2. Liquid and cold construction, simple operation, perfect waterproof effects.
3. Good mechanical, stable weather resistance.
Application
1. Various types of roofs: including cement, bamboo, timber, steel, asbestos shingle,
and different shapes of roofs.
2. Underground structure: inner wall, exterior wall, bottom plate, elevation pit, retaining wall, underground tunnel, well, pipeline of underground concrete.
3. Surface structure: bridge, motorway, toilet, kitchen, bathroom, swimming pool, non-drinking pool, flowerbed.
4. Joint: expansion joint, construction joint, settlement joint, crack in the wall, sprout.
5Antisepsis: metal pipe, antiseptic terrace, antiseptic pool.
Construction main points
1. Construction base shall be strong, clean without dust
2. White coating: black coating =1:2.5, putting blackings into the container first, then adding white coating and stirring well and thoroughly.
3. Knif-coating the base thoroughly with rubber scraper blade, the thickness of coating is 2.00mm, and knifcoating in twice.
4.In order to strengthen the cohesive force between the waterproof layer and protective layer, sprinkling coarse sand or stone grain on the surface before the second coating solidified .
Cautions
1. Not having water on the base, dry first if having the water.
2. Shall be pressurized, running out within one day after unsealing.
3. Avoid from direct sunlight within 3 days if constructed on wet base.
