Surface Substrate must be sound, dry, clean, and free of oil, grease, mildew, efflorescence, and other foreign materials
Preparation and/or contaminants. 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. Remove form oils and efflorescence and grind down
form lines. Fill cracks and holes, and level concrete surfaces with S

Painted Surfaces Lightly sand to dull any sheen and develop “tooth” for good bond. Wash surface with a strong
detergent (e.g. TSP-trisodiumphosphate) from the bottom up to remove any dust, dirt, or sheen.
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 priming bare metal with a good rust-inhibitive primer and let dry prior to the full sur-
face priming.
Substrate Application of a prime coat is necessary to equalize surface porosity. After prepared surfaces have thoroughly

Brand First Coat flat latex paint or a good quality interior latex flat wall
paint with high solids content. Prime coat should be applied undiluted and allowed to dry before decorating.
Mixing Stir until consistency is smooth and uniform.
Thinning Experiment with small amount of mixed material prior to use, adjusting water proportions to match product
viscosity to individual requirements. For thickest finish (heavy trowel, roller, or brush application), use as-is.
For thinnest finish (light roller or spray application), add no more than 1 quart of water per 2 gallon pail.
Aggregate Perlite Up to 1.6 lbs. (0.74 kg) per 2 gal.
Additions
White silica sand Up to 8.6 lbs. (3.9 kg) per 1 gal.
Note: Water is not to exceed 2/3 gal. per 2 gal. pail.
Application
Spray
Use spray equipment similar to Grover 452-A 10-to-1 ratio, double-action pump with
7-1/2 in. stroke, equipped with 4 ft. pole gun with 3/8 to 1/2 in. round orifice; or Binks 7-E-2 handgun with
3/8 in. round openings. Use 3/4 to 1 in. material hose, 3/8 in. atomizing hose, and 1.2 in. air line from
compressor to pump. Compressor must be adequate (85 cfm) for length and size of hose. Keep pressure
as low as possible. Hopper-type applicators may also be used.
Do not exceed recommended coverage, as subsurface defects, variations in base suction, or color differences
may show through, or lighter texture may result. Remove spatters immediately from woodwork and trim.
Stipple Knockdown Use roller, brush, or trowel to apply texture so that a heavy, stippled surface remains. Wait
until material firms slightly. Lightly strike down tops of stipples using flat side of trowel.
Stucco Use roller. Deep pile creates a more textured surface; shallow pile creates a softer look.
Swirls Use whisk broom, trowel, or brush to create gentle overlapping arcs.
Rough ’n’ Tumble Use roller, brush, or spray gun to apply texture. Wrap rope around roller and gently work
over surface.
