Stone Care Sealer - Long Lasting - Type WH6988

GRASi WH6988

GRASi® WH6988 is a long-lasting stone protector, specially developed to provide waterproof performance for various types of stones (such as marble, granite, sandstone, limestone, etc.).

Its nano-scale active ingredients can deeply penetrate into the substrate and bind with it, forming a penetrating protective layer on the surface. With ultra-low surface tension, it has excellent water repellency and a fast beading effect.

Features

Stronger chemical bonding, providing long-lasting protection, good durability, and stability, significantly extending the service life of building materials.
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, can be put into use quickly and dries rapidly.
Performs exceptionally well on natural stone and artificial stone.
Prevents stone loosening, cracking, peeling, and staining, and is easy to clean.
Good chemical resistance, such as acid resistance, alkali resistance, weathering resistance, resistance to chloride ions, and excellent weatherability.
Freeze-thaw resistant, excellent performance at high and low temperatures (-50℃-200℃).
Does not alter the original appearance of the substrate.
Environmentally friendly.

Application Instruction

GRASi® WH6988 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 penetrated. 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. Subsequent treatment can be carried out once the surface is dry.
After complete curing, it will achieve excellent water-repellent effects.
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.
