Stone Care Sealer - Premium Stain Resistant - Type WH6989

GRASi WH6989

GRASi® WH6989 is a special anti-stain stone protector, specifically developed to provide water and oil resistance for various types of stone (such as marble, granite, sandstone, limestone, etc.).

Its nano-scale active ingredients can deeply penetrate and bond with the substrate, forming a penetrative protective layer on the surface. With its ultra-low surface tension, it offers excellent water resistance and rapid beading performance.

Features

Stronger chemical bonding, providing long-lasting protection, good durability, and stability, significantly extending the service life of building materials.
Good permeability to porous substrates.
Prevents water vapor, moisture, and liquid water from penetrating the substrate.
One-way breathability, can repair micro-cracks (0.2 mm - 0.4 mm).
Fast curing, can be put into use quickly and dries rapidly.
Performs especially well on natural and artificial stone.
Prevents stone from loosening, cracking, flaking, and staining, and is easy to clean.
Excellent chemical resistance, resistant to acids, alkalis, weathering, and chloride ions; excellent oil and weather resistance.
Frost-resistant, freeze-thaw resistant, excellent performance at high and low temperatures (-50°C to 200°C).
Does not alter the original appearance of the substrate.
Environmentally friendly.

Application Instruction

GRASi® WH6989 is a ready-to-use penetrating protective agent, suitable for application methods such as spraying, brushing, or troweling.

The surface of the material must be clean and dry.
Use appropriate low pressure for spraying, maintaining a distance of 10-15 cm.
Apply the material onto the substrate until it is fully saturated. For medium to high-density substrates, wipe off excess liquid with a soft cloth 5-10 minutes after application.
Do not place treated materials in humid areas or where they may be exposed to rain; allow to air dry naturally. Subsequent treatments can be applied after the surface is dry.
After full curing, it will achieve excellent water repellency.
The application temperature should be between 2-45℃ (35.6-113°F).
The maximum coverage per liter is 4-35 square meters, depending on the density of the stone.

Performance

Surface dry time	3 hours
Curing time	6-48 hours
