Directions Surface Preparation Substrate must be sound, dry, clean, and free of oil, grease, mildew, efflorescence and other foreign materials and/or conta-
minants. Product, air and surface temperatures must be maintained at a minimum of 55 °F (13 °C) throughout the finishing
process when using joint compound, primer, and texture products.
New Drywall: Treat joints and nailheads with an appropriate USG Joint Treatment System.
New Concrete/Plaster: Age at least 60 days before texturing. For concrete surfaces, remove form oils and efflorescence and
grind down form lines. Fill cracks and holes, level offsets and voids to the same level as adjacent surfaces with S

and let dry. Apply as many coats as are needed to provide a crack-free fill without edge joinings that show through decoration.
Painted Surfaces: Lightly sand to dull any sheen and develop “tooth” for good bond. Wash surface with a strong detergent
from the bottom up to remove any dust, dirt, or sheen. A strong solution of TSP (trisodiumphosphate) works best.
Note: Texturing over previously painted, textured, or stained substrates may require application(s) of a stain-blocking sealer to
obtain uniform color (check manufacturer’s instructions for stain containment instructions). Prevent rust stains by spot prim-
ing bare metal with a good rust-inhibitive primer and let dry prior to the full surface priming.
Substrate Priming Application of a prime coat is necessary to equalize surface porosity. After prepared surfaces have thoroughly dried, apply a
prime coat of S

Brand First Coat flat latex paint or a good quality interior latex flat wall paint with high solids con-
tent. Prime coat should be applied undiluted and allowed to dry before decorating.
Mixing Using a clean mixing vessel, add recommended amount of water per instructions on bag. Sift texture into the water using a
power agitator to blend texture and water. Mix initially at a heavy viscosity to disperse the powder and eliminate lumps. Allow
