WP1321 Resistant Chloridion Waterproof Preservative
GRASi® WP1320 is a high effective waterproof agent developed to provide water&oil repellency for porous construction materials such as concrete, cement etc. The active ingredients which is nano-size penetrate deeply into the substrates and bond with them, form penetration protective layer on the surface. With super low surface tension, it boosts excellent water repellency and fast beading action.

Features
- Stronger chemically bond, long lasting protection, good durability, good stability, extend the lifespan of building material obviously
- Good penetration into porous substrates, good abrasion resistance · Use when the temperature is between 2℃- 45℃（35.6-113°F）.
- Maximum coverage per liter is 4-12 square meters, but depends on substrate density.
- Resist water vapor, moisture and liquid water into substrate
- One-way breathable, repair tiny crack (0.2mm-0.4mm)
- Quickly for using and quick dry
- Especially perform well on high density concrete
- Chemical resistance such as acid, alkali, chloride ion, carbonation; weather, UV resistance - Excellent
- Frost proof, anti freezing and thawing and resist high Storage
- Keep sealed and store in cool and dry place, use within 18 months.
- Keep away from children.
- Keep away from flame and heat. Performance after best treatment temperature(-50℃-200℃）- Excellent
- Does not change surface appearance · Environmentally friendly
Applications
For use on cementitous substrates such as concrete and mortar that require water repellency. Such as bridge structure, port,pier, airport apron, highway pavement, overpass, parking lot, warehouse, refrigerated warehouse, city square, garage, swimming pool,building indoor & outdoor wall finishing and roof covering etc .

Application instruction
GRASi® WP1321 is ready to use penetrating water repellent.
Material surface must be clean and dry .
Spraying, brushing, soaking or rolling are suitable for this application. Please apply under the condition of natural ventilation.
Spray with suitable low pressure, 10-15cm distance away.
Apply the material on substrate until it's thoroughly saturated.
Don't put treated material to moisture or rain place, and dry it in natural air. When the surface is dry, further treatment can be followed.
After complete curing, it will form an outstanding hydrophobicity.
Use when the temperature is between 0℃- 40℃（32-104°F）.
Maximum coverage per liter is 4-5 square meters, but depends on substrate density.
Storage
- Keep sealed and store in cool and dry place , use within 18 months.
- Keep away from children.
- Keep away from flame and heat.
