Specification

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
h e e t r o c k
®
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 Use a clean mixing vessel equipped with a variable speed power agitator. Depending on desired texture pattern,
start with up to 3.75 gal. (14.195 L) water per 50 lb. (22.68 kg) bag. Using drinkable water and clean mixing
equipment, slowly add dry powder texture to the water in a mixing vessel and mix to a heavy but lump-free
consistency. Allow to soak for at least 15 minutes—longer in cold water. Remix until mixture has a wet, smooth
and creamy appearance. Adjust to desired spray consistency by adding small amounts of water to the wet mix
(up to 3/4 gal. additional water for bold patterns, or up to 1.8 gal. additional water for light patterns). Total water
should not exceed 4.6 gal. (17.413 L) per 50 lb. (22.68 kg) bag. DO NOT overthin, as poor adhesion, lack of
hide or texture variation may result. If additional hardness and bond are desired, add up to 1 gal. of S
h e e t r o c k
First Coat. (Note: Substitute volume of additives for equal volume of mixing water.) DO NOT intermix with any
materials other than those recommended by USG.
Application Using professional equipment, apply by machine or hand to create the desired effect. Application rates will vary
depending on the texture pattern of choice. Generally, the application rate will vary from 20 ft.
