Penetrating Water Repellent Sealer - Fast Drying - Type WH6980

Penetrating Water Repellent Sealer - Fast Drying - Type WH6980

GRASi WH6980

GRASi® WH6980 is a fast-drying waterproofing penetrant, specially developed to provide waterproofing performance for porous building materials such as bricks, concrete blocks, mortar, and grout. It uses a new generation of nano-silicon compounds that can form a protective layer on the surface of materials, significantly reducing surface energy and offering excellent water repellency and rapid beading effect.

Its active ingredients are composed of a mixture of particles of different sizes, including nanoparticles, which not only ensure good penetration for long-lasting protection but also provide excellent surface coverage to achieve a beading effect. By forming a chemical bond with the substrate, it can provide long-term protection.

Features

The treated substrate has rapid and excellent water droplet condensation and waterproof performance.
Good penetration for porous substrates.
Allows water vapor to pass through but blocks liquid water.
Forms chemical bonds to provide long-lasting protection.
Fast curing speed, can be put into use quickly.
Environmentally friendly.
Alkali-resistant after treatment.
Excellent chemical resistance, resistant to acids, alkalis, chlorides, frost, and has outstanding weather resistance.
Excellent wear resistance.

Application Instruction

GRASi® WH6980

The surface of the material must be clean, dry, and free of stains.
Use appropriate low-pressure tools for spraying, keeping a distance of 10-15 cm; an airless spray machine can also be used.
Apply the material to the substrate until it is fully soaked.
Avoid contact with moisture or rain, and allow to air dry. After 24 hours of complete curing, it will form excellent water repellency.
The maximum coverage is 4-5 square meters per liter, depending on the density of the substrate.
Do not apply when the temperature is below 2°C (35.6°F).
