WH6983 Waterproof Penetrant - Nano Permeable Type

GRASi® WH6983 is a high effective waterproof agent developed to provide water repellency for porous construction materials such as aerated concrete block, cement, mortar, concrete, ceramic tile, tile, building insulation material and light weighted composite construction material 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 bonded, long lasting protection, good durability, good stability, extend the lifespan of building material obviously
Good penetration into porous substrates, good abrasion resistance
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,
Frost proof, anti freezing and thawing and resist low/high
Does not change original appearance
Environmentally friendly

Applications

For use on cementitous substrates such as concrete and mortar that require water repellency. Such as all type of concrete cement for bridge instructure, port, pier, airport apron, highway pavement, overpass, parking lot, warehouse, refrigerated warehouse, city square, garage, building interal & exteral walls finishing and roof covering etc .

Application instruction

GRASi® WH6983 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. For middle or high density substrate, it needs to wipe up excessliquid with soft cloth after apply for 5-10 minutes.

Don't put treated material to moisture or rain place, and dry in natural air. When the surface is dry, further treatment can be followed. ·After completely curing, it will achieve an outstanding hydrophobic effect.

Apply 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.

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

Surface dry time	2 hours
Curing	4-48 hours
DOP on cement/mortar	2-6 mm
Extend weather durability	8-10 years

Remarks: curing in lab, 25℃
