Applications

Use a Squirrel Mixer® (1 gallon size) with a variable speed drill, according to the manufacturer’s recommendations. Add the hardener slowly and evenly into the mixing vortex in the resin component, while maintaining a constant mixing speed throughout the addition. Avoid entraining air. Continue mixing for a minimum of three minutes. Proper mixing of the viscous hardener into the low viscosity resin component is essential to achieve proper coating properties. Filter before use. Mixed product has a pot life of 2 hours at 25°C.

Surfaces

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 ECO PRIME520. Apply 1 - 2 coats of FORTIS ECO PRIME520, followed by 1 or 2 coats of FORTIS COAT526 Gloss or Satin depending on required finish
