When I mix these products, I get lots of bubbles and the coating looks foamy, even cloudy sometimes, what causes this?

This is a sign of mixing cold resin and hardener together. To prevent this, one should place the product bottles in your hands, if they feel “Cool” or “Cold” the bottles should be placed in “Warm” tap water for 5 to 10 minutes prior to using. Warming the product up will help to lower the viscosity of the coating, which will greatly diminish the amount of bubbles from mixing.
