Application Sheet

Surface Preparation
Proper surface preparation is vital for long-term performance. The prepared concrete surface must be structurally sound, free of all contaminants, and roughened to a profile >ICRI CSP 3 (similar to #60 grit sandpaper). Taurus T497 can be applied directly to concrete to create a vapor barrier.

Mixing
Thoroughly mix the activator into the base using a mixing stick, scraping the sides and bottom of the container. Mix by weight at a ratio of 1.9 parts Base to 1 part Activator. Mix thoroughly until a uniform, streak-free material is obtained. Never add solvents.

Application
Brush: Medium to stiff bristles of sufficient quality to prevent shedding or bristles sticking to the coating (epoxy-set bristle brushes are preferred). Cutting or masking: Use tape with <1″ nap. Roller: Use good quality 1/8″ nap.

Application Temperature:
Application temperature range from 10°C (50°F) to 32°C (90°F) (substrate).For maximum protection against immersion or spills, a two-coat system is recommended. To avoid sagging on vertical surfaces, the maximum wet film thickness should be between 500µm and 1000µm (20–40 mils) per coat.

Cured Time:

16°C (60°F) 25°C (77°F) 32°C (90°F)
Tack Free 4 hours 2 hours 1 hour
Light Load 12 hours 6 hours 3 hours
Term Overlay 16 hours 10 hours 5 hours
Full Charge 24 hours 12 hours 6 hours
Complete Chemical 48 hours 24 hours 12 hours

Clean: Tools should be thoroughly cleaned immediately after use with a strong alkaline detergent.

Safety: Before using any product, review the Safety Data Sheet (SDS) or Safety Data Sheet for your area. Follow standard confined space
