Chemically bonds to siliceous and most polar compounds.
Cures well in humid and cold conditions.
For new wood and fully sanded old timber surfaces, final sand with 220 grit sandpaper.
For concrete surfaces, best results are obtained from diamond-grinding followed by etching with Fortis CCA Acid based cleaner to remove the grinding debris and to lower the concrete pH. After the CCA cleaner has dried, prime the surface with Fortis Polyurethane Adhesion Promoter. Allow 2-4 hours for Promoter to fully react, then apply the Fortis PRIME520.
Apply 1 - 2 coats of FORTIS PRIME520, followed by 1 or 2 coats of FORTIS COAT526 Gloss, Satin or Matt depending on performance required.
