Application steps

APPLICATION

Precut Sika® Fleece-120 (US) and dry fit to horizontal field and vertical flashing conditions. Temporarily remove fleece. Apply approximately 2/3 of the specified resin quantity to primed substrate surface with a 1/2” (12.7 mm) nap phenolic resin core roller. Immediately fit and place Sika® Fleece-120 (US) into wet resin, overlapping reinforcement 3” (76.2 mm) along the sides and 6” (152.4 mm) at the roll ends. Apply wet roller to topside with light pressure to saturate from bottom and to ensure that air pockets are completely removed. Immediately apply the remaining 1/3 of the specified resin quantity and apply wet roller to topside with light pressure to fully saturate the membrane to achieve an even texture and appearance.
