WH6982 Waterproof Penetrant - Emulsion Enhancement Type

GRASi® WH6982 is an emulsion high effective waterproof agent developed to provide water repellency for porous construction materials such as bricks, concrete blocks, mortar and grout. New generation nano-silicon compound is used to give a protective layer on the surface. It will reduce the surface energy obviously, it boosts excellent water repellency and fast beadingaction.

The active ingredients are mixture of different particle sizes includingnano-particleensuring good penetration for durability as well as good surface coverage for beading effect. With chemical bonds of substrates, it will provide long lasting protection.

Features

Treated substrates show fast and excellent water beading and repellency.
Good penetration into porous substrates.
Water vapor permeable but resistant to liquid water
Chemically bonded, long lasting protection
Chemically bonded, long lasting protection
Fast curing, quickly for use
Maximum coverage per liter is 4-5 square meters, but depends on substrate density.
Environmentally friendly

Application instruction

GRASi® WH6982 is ready to use penetrating water repellent, spraying, brushing, soaking or rolling are suitable for application.

Material surface must be clean and dry .

Spray with suitable low pressure, 10-15cm distance away.

Apply the material on substrate until it's thoroughly saturated. For middle or high density substrate, it needs to wipe up excess liquid with soft cloth after apply for 5- 10 minutes.

Don’t expose it to moisture or rain, and dry it in natural air. After full curing in 24 hours, it will form an outstanding hydrophobicity.

Apply when the temperature is between 2℃- 45℃(35.6-113 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.
