FAQ

Does BOSLAI metal roof coating prevent rust and corrosion?

Yes. The coating contains anti-corrosion and anti-rust additives that form a dense protective membrane over the metal surface, blocking moisture and oxygen. For best results, wire-brush loose rust particles before application.

Can BOSLAI metal roof coating reduce roof temperature and save energy?

Yes. The formula includes high-reflectivity fillers that reflect solar radiation, reducing heat absorption into the building. White and light-colored formulations provide the best cooling effect.

Can BOSLAI metal roof coating be applied on color steel tiles and containers?

Yes. It bonds well to color steel tiles, galvanized steel, corrugated metal sheets, and steel containers. Clean the surface by removing loose rust and debris before application — no primer required.

Does BOSLAI metal roof coating hold up in extreme weather — coastal, tropical, or freezing climates?

Yes. It resists UV, acid rain, salt spray, and extreme temperatures. No cracking at -10°C, stable up to +80°C. Suitable for coastal, tropical, and temperate zones alike.

What colors and packaging options are available?

White and light colors for maximum heat reflection. Custom colors available (reflectivity may vary). Packaging: 18kg or 20kg or 50kg pails. Full OEM — custom brand, label, and packaging — available for distributors.

How to find a reliable metal roof coating supplier worldwide?

Check for: (1) TDS available before ordering, (2) dedicated waterproofing manufacturer, not a general trader, (3) anti-corrosion additives included, (4) heat-reflective technology if energy savings matter, (5) OEM capability for your brand. BOSLAI meets all five — TDS downloadable, sample support available, OEM customized.
