Test the spray pattern prior to application. Toapply, hold spray gun perpendicular to thesurface approximately 30 to 45 cm away. Movethe gun parallel to the surface at a steady rate.Lap each stroke approximately 50% over theprevious stroke for uniform paint thickness.Spray from left to right to scratch in the initialcoat at approximately half of the desiredthickness. Then crosshatch spray up and downas the double-up coat to the thickness. Whenpainting corners, aim the gun toward the centreof the corner to ensure both sides are sprayedevenly. When used in lieu of a skim coat ofjoint compound and paint primer coat in a Level5 gypsum board finish, apply to a minimum WetFilm Thickness (WFT) of 0.38 mm. In allapplications a wet film thickness in excess of0.51 mm is not recommended.

Drying TimeDries to touch in approximately 60 - 90minutes when applied at 0.38 to 0.50 mm(15-20 mils) WFT under normal dryingconditions (24°C/50% RH). Let dry beforere-coating. High humidity and/or coldtemperature will slow drying.
CoverageApproximately 50 – 62.5 m2 per 18.9 litre pailwhen applied at 0.38 to 0.50mm (15-20 mils)WFT. Actual coverage can vary depending onfactors such as substrate surface condition,spray techniques, procedures, coatinguniformity, and thickness.
DecoratingMay be painted after overnight drying.Follow paint manufacturer’s instructions.May be left unpainted.
