FORTIS Coat 526 is a high-performance, two-component water-based polyurethane coating designed to protect and enhance concrete and timber surfaces. Its clear, UV-stable formulation provides excellent wear and abrasion resistance while maintaining a natural appearance.
With ultra-low VOC content of less than 10 g/L and low odour, Coat 526 is suitable for residential and commercial flooring, concrete benchtops, walls, stairs and timber floors.
Gloss: Self-priming on suitably prepared concrete and timber. Use Coat 526 Gloss for the initial, build and final coats.
Satin: Designed as the final coat over Coat 526 Gloss. Apply Gloss for the initial and build coats, followed by Satin to achieve the desired lower-sheen finish.
A typical system requires 2–3 coats, depending on the substrate and finish required. Coverage is approximately 12–15 m²/L per coat.
Coat 526 can be applied by brush, roller or spray. The two components are mixed at 4.5 parts A to 1 part B by volume.
Two-component water-based polyurethane
Surfaces must be clean, dry, sound and suitably prepared. Remove contaminants that may affect adhesion. Coat 526 Gloss is self-priming on properly prepared concrete and timber; a separate primer is not normally required.
Stir Part A thoroughly. Mix 4.5 parts A with 1 part B by volume. Slowly add Part B while mixing with a suitable variable-speed mixer. Avoid introducing air and mix for at least 3 minutes. Filter if required.
Apply by brush, roller or spray at 12–15 m²/L per coat. For rolling, pour mixed material in ribbons across the surface and use a 5 mm nap microfibre roller.
Gloss: Use Coat 526 Gloss for the initial, build and final coats.
Satin: Use Coat 526 Gloss for initial and build coats, followed by Coat 526 Satin as the final coat.
Apply 2–3 coats in total. Working time is 45–60 minutes; pot life is 2 hours at 25°C.
Recoat after 6–24 hours at 20°C. Maximum recoat interval is 48 hours. Tack-free time is approximately 2–3 hours, with full cure after 7 days. Apply between 10°C and 35°C. Avoid conditions that may cause condensation on the uncured coating.
Clean equipment with water immediately after use. Hardened material requires mechanical removal.
System requirement: Coat 526 Gloss is self-priming on suitable concrete and timber. Coat 526 Satin must be applied as the final coat over Coat 526 Gloss.
