GRAE-400-GRAE C00lRooftop
Thermal insulation top coat paint
GRAE COOL ROOFTOP
Product Overview
– Special additives such as high elastic acrylic emulsion, water-based urethane resin, fine silica powder, UV protection, etc.
– Reflects solar heat to suppress internal temperature rise
– A product with excellent contamination resistance as a thin film with a smooth surface is possible
Product Features
1) Energy saving by lowering the indoor temperature by reflecting sunlight on the surface
2) High elasticity, strong against external influences, and strong contamination resistance with smooth coating
3) Excellent waterproof effect due to dense matrix structure of powder and acrylic emulsion
4) One-component water-based product that can be easily installed with confidence
5) Long life and eco-friendly product with excellent weather resistance and adhesion

Construction method
– Removes laitance, oil and other contaminants from the bottom surface, and fills grooves and cracks with elastic putty or quick tie
– Apply graphite insulation evenly with brush, roller, spray, etc.
– The repainting interval should be applied after confirming that it has been dried after 1~5 hours at room temperature, and applied at least 3 times.
– When dilution, the water should be within 5% and sufficiently stirred for at least 5 minutes using a low speed stirrer.
– When thickness is required, spray or plaster after stirring the exclusive powder and liquid in a ratio of 1: 3 to 5(powder)
