Preparation In cold weather during gypsum panel joint finishing, minimum surface, water, mix, and air temperature of 45 °F must
be ensured until joints are completely dry.Adequate ventilation shall be provided to carry off excess moisture.
Gypsum Panel Position and apply gypsum panels in accordance with manufacturer’s recommendations.Mix compound according
Joint Treatment to directions on bag. Allow prefill compound to harden prior to the next application (tape-embedding coat).
Cover joint with a thin layer of compound and embed tape, leaving about 1/32 of compound under feathered
edge and a thin layer over the tape. After compound has set, apply second coat, feathering out approximately
2 beyond first coat. After setting, apply third coat, feathering out 2 beyond second coat.After each coat is
applied, smooth away any tool lap marks or other imperfections prior to hardening action. Finish fastener heads
with three coats of joint compound; finish corner bead and inside corners as required with at least two coats,
feathered and smoothed out onto panel faces.
For priming and decorating with paint, texture, or wallcovering, follow manufacturer’s directions for materials
used. All surfaces must be dry, dust-free, and not glossy. A prime coat of a USG primer product or a goodquality interior latex flat wall paint with high solids content should be applied undiluted and allowed to dry
before decorating. Walls to be covered with wallpaper or vinyl wallcovering should be sealed per manufacturer’s
recommendations. To improve fastener concealment where gypsum panel walls and ceilings will be subjected
to severe artificial or natural side lighting and be decorated with a gloss paint (eggshell, semigloss, or gloss),
the gypsum panel surface should be skim-coated with joint compound to equalize suction before painting
(see USG publication J510).
Filling and Finishing Grind high plane differences in concrete level with adjacent area; also remove any form oil, efflorescence, and
over Interior greasy deposits. Prime exposed metal with a good rust-inhibitive primer. Fill offsets or voids with joint compound.
Poured Ceilings Apply additional coats of joint compound as necessary, after each coat has set, but not necessarily dried.After the
final coat of joint compound has dried, apply an undiluted coat of a USG primer product or a good quality latex flat
wall paint with high solids content over entire surface and allow to dry. For textured ceiling, apply USG Ceiling
Spray Texture in a uniform coat at a rate not exceeding 10 ft.

Use with SHEETROCK In areas to be tiled, for tapered edge joints, embed USG Joint Tape with SILVER SET 40 or 90. When set, apply a
Brand Gypsum Panels, fill coat. Take care not to crown the joint. Wipe excess joint compound from the panel surface before it hardens.
Water-Resistant For butt joints and interior angles, embed USG Joint Tape with S
ILVER SET 40 or 90.A fill coat is not necessary.
Again, take care not to crown the joint. For fasteners,spot fastener heads at least once.
Fill and seal all openings around pipes, fittings, and fixtures with a thinned-down coat of tile adhesive. For best
results, use Type I Ceramic Tile Adhesive that meets ANSI A136.1 both as a sealer and to set the tile. With a 1
brush, apply the thinned compound onto the raw gypsum panel core at cutouts, and allow area to dry
thoroughly prior to application of tile. Before compound dries, wipe excess material from the surface of gypsum
panels. For areas not to be tiled, embed tape in the conventional manner. Finish with at least two coats of
USG Joint Compound to provide joint finishing for painting and wallpapering.
Laminating Apply joint compound in the prescribed manner to back of face panels to be laminated.Laminate face panels to (base
layer panels) (coreboard) using moderate pressure and temporary nailing or shoring to ensure adequate bond.
Finishing For painting and decorating, follow manufacturer’s directions for materials used.
