Stone Care Sealer - Color Enhancing - Type WH6987

GRASi WH6987

GRASi® WH6987 is a color-enhancing stone protector, specially developed to provide color-enhancing and waterproofing performance 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 waterproofing and rapid beading effects.

Features

Stronger chemical bonding, providing long-lasting protection, good durability, and excellent stability.
Can enhance the color of stone.
Good permeability for porous substrates and excellent wear resistance.
Prevents water vapor, moisture, and liquid water from penetrating the substrate.
One-way breathability, can repair tiny cracks (0.2 mm - 0.4 mm).
Fast curing speed, allowing quick use and rapid drying.
Performs particularly well on natural and artificial stones.
Prevents stone loosening, cracking, flaking, and staining, easy to clean.
Excellent chemical resistance, such as acid, alkali, weathering, chloride resistance, and excellent weather resistance.
Frost-resistant, freeze-thaw resistant, excellent performance at high and low temperatures (-50°C to 200°C).
Environmentally friendly.

Application Instruction

GRASi® WH6987 is a ready-to-use penetrating waterproofing agent, suitable for application by spraying, brushing, or troweling.

The surface of the material must be clean and dry.
Use appropriate low pressure for spraying, at a distance of 10-15 cm.
Apply the material to the substrate until 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 damp or rainy areas; allow them to air dry naturally. Once the surface is dry, subsequent treatments can be carried out.
After complete curing, it will achieve excellent hydrophobic effects.
The application temperature should be between 2-45°C (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
Extend weather resistance lifespan	≥10 years

Note: Laboratory curing conditions, 25°C.
Reminder: When the product is used for major engineering projects, it is recommended to conduct testing in advance.

Storage

Store sealed in a cool, dry place and use within 24 months.
Keep away from children.
Keep away from fire and heat sources.
