Drying Time:Varies by air temperature, humidity and surface temperatures. Under normal room temperatures Clearshield will dry to the touch in 10 minutes, ready to re-coat in 6 hours if desired. Protect work from rain and temperatures less than 45°F (7°C) for a minimum of 24 hours.
Storage & Shelf Life: Store above 40°F and below 110°F (5°-43°C) and out of direct sunlight. Shelf life is approximately two years under these conditions.
Application Procedure
