Sanwin SC702 High-gloss Topcoat is a colorless and transparent acrylic pavement paint. It is commonly used as the surface layer of colored anti-skid pavements and is usually applied last in construction. The high-gloss topcoat not only stabilizes the aggregate but also prevents dust accumulation on the pavement surface, keeping it clean. Properly applied high-gloss topcoat can extend the service life of colored pavements to more than 3 years and make them easy to clean. SC702 High-gloss Topcoat can enhance the color of colored ceramic particles and improve the landscape effect of colored anti-skid pavements.

Construction Recommendations
Surface Coating
The primer is completely cured, the aggregate is firmly attached, and excess aggregate has been removed. The surface to be coated is dry and flat.
Environment
The acceptable operating environment temperature is 5-45℃, and the ground humidity should not exceed 70%RH.
Premixing
Add the curing agent to the coating in proportion and stir evenly at low speed with an electric mixer.
Application
Evenly apply the coating to the surface of anti-skid aggregate using a roller brush or special tools.
Aggregate
Recommended aggregate particle size is 1-5mm
Cleaning
A sufficient amount of cleaning agent should be provided at the construction site. Tools should be cleaned immediately after construction; otherwise, it will be difficult to clean once the coating is completely cured.
