Wood Protective Sealer - High Performance - Type WH6991

GRASi WH6991

GRASi® WH6991 is a high-efficiency wood protector, specifically developed to provide waterproof performance for wood products (especially for raw wood products). 

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

Features

  • Stronger chemical bonding provides long-lasting protection, good durability, and excellent stability.
  • Reduces deformation or warping of wood products caused by moisture.
  • Moisturizes wood fibers, stabilizing the moisture content within a relatively small range, reducing cracking of wood products.
  • Prevents water vapor, moisture, and liquid water from penetrating the substrate.
  • Fast curing speed, allowing quick use and rapid drying.
  • Prevents wood from cracking, blackening, and staining, and is easy to clean.
  • Good chemical resistance, such as resistance to acids, alkalis, and chloride ions; good weather resistance.
  • Frost-resistant, freeze-thaw resistant, and resistant to high and low temperatures (-50℃ to 200℃).
  • Environmentally friendly.

Application Instruction

GRASi® WH6991 is a ready-to-use penetrating waterproofing agent.

  • The material surface must be clean and dry.
  • Suitable for spraying, brushing, dipping, or rolling. Please apply under natural ventilation conditions.
  • Use appropriate low pressure for spraying, at a distance of 10-15 cm.
  • Apply the material onto the substrate until fully penetrated.
  • Do not place treated materials in damp or rainy areas; allow them to air dry naturally. Once fully cured, it will form excellent hydrophobicity.
  • Application temperature should be between 2-45℃ (35.6-113°F).
  • Maximum coverage is 5-10 square meters per liter, depending on the density of the substrate.
