Using a solvent resistant brush or roller, apply Icopal SA Primer at a rate of 0.12-0.25 L/m², depending on type and absorbency of substrate. Apply a thin and even coat, and avoid pooling. Primer to be dry to touch prior to application of the self-adhesive membrane. Icopal SA Primer should not be applied to wet surfaces.
