Application

Small quantities can be mixed by hand. Gradually add 2 parts by volume of powder to 1 part by volume of clean water and thoroughly mix to the consistency required. Allow the product to stand for approximately 2-3 minutes after mixing to allow all of the high performance additives to fully dissolve and wet out before remixing the product to a smooth creamy consistency. Apply with a notched/smooth steel trowel, coarse roller, spray pump, blade or filling knife. Notched trowel and roller application techniques require smoothing after application to the substrate, with a large straight edge/smoothing blade to create a smooth uniform finish. All application techniques can be smoothed with a straight edge/smoothing blade. Apply at temperatures above 5°C.

All information on surface preparation, mixing, thicknesses and drying times can be found on the technical datasheet.
