Mirrorcoat Heat Resistance/Temperature Tolerance
The rule of thumb with cured Mirrorcoat® and how much heat it will tolerate is this: If an object is not too hot to hold in your hand, you can set it directly on a Mirrorcoat surface which is completely (more than a week) cured. If it is hotter, you must place a coaster or hot pad underneath the object.
If you happen to put an object that is too hot on a Mirrorcoat surface, and it leaves a ring, the ring can many times be removed by passing a hairdryer back and forth over the affected area.
How is Mirrorcoat applied?
Mirrorcoat epoxy has cured with some sticky spots. How do I fix it?
The sticky spots are most typically uncured resin or hardener which hasn't been completely mixed in. If it's excess resin it can be removed with a strong solvent like lacquer thinner. If it's excess hardener it can be removed with soap and water. The voids can be filled with small quantities of newly-mixed Mirrorcoat, carefully using a spatula or squeegee to smooth out any excess material. Let this cure 24-hours and lightly sand the surface with medium-coarse sandpaper. Finally, apply an additional flood coat at 4 fluid ounces per square foot.
