Five kilogram (11 Lbs) covers up 60 – 80 sq. ft. on a smooth wall, significantly less on acoustical tile or rough surface. We do not recommend thinning down the plaster but if you wish to create other effect, thinning not more than 1 oz. (29.6ml mL) of water per 11 Lbs (5kg) of plaster.
Plaster only when surface and air temperatures are 50-90 °F (10-32 °C), wait 8 hours before recoating or 24 hours before applying MACOAVELL VELLWAX.
