Application steps

MIXING

Thoroughly stir the entire container of Liquid resin with a slow-speed (200 to 400 rpm) mechanical mixer (electric drill with a mixing blade) for two to three minutes before each use, and prior to pouring off resin into a second container if batch mixing. Only catalyze the amount of material that can be used within 10 to 15 minutes. Add pre-measured Catalyst Powder to the resin component and stir for 2 minutes. The amount of catalyst required is determined by resin weight and ambient temperature

APPLICATION

After mixing, apply Sikalastic® Rapid Primer ASP to substrate at the required consumption using a 3/8 in nap roller or brush. The resin should be applied evenly onto the surface using care not to spread too thin or pool in low areas.
