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

dried, apply a prime coat of S

HEETROCK

®

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.
