YOOGU Concrete High-Elasticity Waterproofing System is composed of a special environmentally friendly high-quality acrylic waterproof coating, supplemented with polyester fabric. After curing, it forms a seamless and complete roof waterproofing system. Through hundreds of tests, and multiple adjustments and optimizations of its technology and formula, various test data of the product show that it offers excellent resistance to alkalinity and acid rain, possesses outstanding toughness, and demonstrates extremely strong waterproof functionality. It is resistant to acid, alkali, and salt; exhibits superior resistance to hydrostatic pressure; has good impact resistance, long-term anti-mold and antibacterial properties, and anti-algae capabilities, along with a long service life. It prevents rainwater from channeling beneath the original waterproof layer, complements various substrate materials with a combination of rigidity and flexibility, and exhibits extremely strong adhesion. This concrete roof waterproofing system is the most advanced, economical, and reliable high-elasticity seamless waterproofing system domestically. The product is extremely convenient to construct and has a wide range of applications. It is a high-tech product with a high cost-performance ratio that is urgently needed in the current market, possessing very broad market prospects.

1. It can be directly applied for waterproofing construction on various substrate materials and old waterproof layers, with a fast curing speed. 

2. It exhibits exceptional anti-seepage performance, particularly on the negative water pressure side (the side opposite to the water source). 

3. The formula incorporates strong hydrophobic agents, giving the coating interface a "lotus leaf effect" when encountering water. 

4. It possesses weather resistance, high tensile strength, tear resistance, flexibility, and abrasion resistance, effectively adapting to substrate deformation and cracking. 

5. It compensates for the shortcomings of membrane materials in handling internal/external corners and the lapping areas between two materials, achieves strong adhesion to various substrates, and integrates 100% with the substrate to form a seamless, monolithic waterproof layer. 

6. It demonstrates excellent resistance to hydrostatic pressure, good impact resistance, and long-term anti-mold, antibacterial, and anti-algae properties. 

7. It features aging resistance, corrosion resistance, crush resistance, a tough coating, high strength, and high elasticity, with a service life of over 15 years.

Applied on substrates such as new and old concrete roofs, basements, water tanks, retaining walls, foundations, swimming pools, bathrooms, metal materials, stone, and membrane materials, it has been widely used across various regions nationwide. After construction, it forms a seamless waterproofing system for the waterproof layer.

Three-Coat-One-Cloth Waterproofing Construction Process

1. Mix the waterproof coating evenly according to the ratio, clean the base surface of debris, ensuring it is level, dust-free, and free of water or oil.

2. First Coat: Apply a coat of specialized high-elasticity flexible acrylic base waterproof coating for concrete on the prepared base surface.

3. One Cloth: While the base coat is still wet, lay the pre-cut polyester cloth flat over it. Press it firmly with a brush, allowing the base coat to permeate through the polyester cloth.

4. Second Coat: Immediately apply another coat of the specialized high-elasticity flexible acrylic base waterproof coating for concrete over the polyester cloth. Ensure the base coat fully saturates the cloth, avoiding blistering or wrinkling, so that the two coats and one cloth integrate into a seamless waterproof layer. Allow to cure for 8 hours.

5. Third Coat: Apply a final coat of specialized high-elasticity flexible acrylic surface waterproof coating for concrete over the cured two-coat-one-cloth base. Allow it to dry completely for inspection and acceptance.

 

Precautions:

1. When using, mix Components A and B of the coating in a 4:1 ratio in a bucket. Stir with a mixer for 5-10 minutes until uniform, then let it sit for 10 minutes before use.

2. The mixed coating must be used within one hour, as it will thicken and cure rapidly beyond the usable time. Prepare only the amount needed for the immediate work area to avoid waste.

3. For cracks wider than 1-2 cm on the construction surface, first seal them with hydraulic sealant before applying the waterproof coating.

4. Application Method: Use a cross-brushing technique (vertical and horizontal strokes) for each coat.
