For priming and decorating with paint, texture or wallcovering, follow manufacturer’s directions
for materials used. All surfaces, including applied joint compound, must be thoroughly dry, dust
free and not glossy before decorating.
Drywall Primer: A priming material applied over the entire prepared gypsum panel surface prior to
decoration. The priming material must be suitable for the substrate and applied as recommended
by the coating manufacturer. Where final appearance is critical, the application of a flat drywall
primer with high pigment solids tends to minimize most decorating problems.
A prime coat of USG Sheetrock® Brand First Coat™ Primer or a good quality interior latex flat wall
paint with a high pigment solids content should be applied undiluted and allowed to dry before
decoration. Walls to be covered with wallpaper or vinyl wallcovering should have the surface
treated per the wallcovering manufacturer’s recommendation.
USG Sheetrock® Brand ready-mix joint compounds can be used in a skim coat operation when
properly prepared as a skim coating material. Refer to USG literature Finishing & Decorating
Gypsum Panels (J2010) for information regarding skim coating with USG Sheetrock® Brand ready-
mix joint compounds.
Factors not covered in this publication may also aect the finished appearance of any surface.

FROZEN MATERIAL GUIDELINES
1
1. In the event the material is frozen, allow it to thaw completely.
2. Do not apply any form of heat to container.
3. Open the container carefully to prevent spilling any separated liquid. This is not water and
must be remixed into the compound.
4. Do not add water until the material is remixed. Once the material remixes to a smooth,
lump-free consistency, water may be added per USG recommendations to obtain the desired
working properties. Do not use if the material is not smooth or lump free after remixing
