Mixing is the key to a thorough cure, good films, and strong bonds. 1 to 2 minutes of aggressive mixing, swiping the sides and bottom is recommended. Use clean plastic or uncoated paper cups or buckets and a clean mix stick. Blush may form over the Fast mix hardener and resin. The Slow mix will not blush.
Blush is noticeable as a slippery film formed over the cured surface.
If more than 30 hours pass between coats, we recommend a light scuff sand. Always check for blush on surfaces. For clear coating, we like to see temperatures remain over 55 to 60 F. For bonding, anything over 45 is adequate. Below 60 we recommend using Cool Cure resin and hardener. Latex gloves and other personal protection should always be used.
