INSTALLATION RECOMMENDATIONS

To ensure the best results, use only products from ProForm Finishing

Products together in your construction systems. We do not recommend

mixing our products with other brands. All ProForm joint compounds
are formulated without asbestos and therefore comply with Consumer

Product Safety Standards.

General

Install All Purpose Joint Compound according to the methods
described in “Applicable Standards And References” and as indicated

in this section. Lightly mix before using and before adding water.
(Add water carefully to thin to desired consistency.) Mix with a potato-
masher-type tool or with a low-speed drill.

Use directly from the container for treating fasteners and cornerbeads

or for taping and finishing joints. Apply a uniformly thin layer of joint
compound over the joint approximately 4 in. (102 mm) wide. Then
center the tape over the joint and embed into the compound, leaving
sufficient joint compound under the tape to provide a proper bond. Cover
the tape with a thin coat of compound to minimize wrinkling or curling.

Reinforce ceiling, wall angles and inside corner angles with the tape

folded to conform to the angle and embedded into the compound.

Once the compound is thoroughly dry (approximately 24 hours), cover
the joint tape with a coat of all-purpose joint compound or topping

compound spread approximately 3 in. (76.2 mm) on each side and

feathered out at the edges. After this coat is thoroughly dry, apply
another coat of all-purpose joint compound or topping compound with
a slight, uniform crown over the joint. This coat should be smooth

and the edges feathered approximately 3 in. (76.2 mm) beyond the

preceding coat. Coat all inside corners with at least two coats of
compound with the edges feathered out.

Apply three coats of compound to all nail or screw head dimples.
Apply these coats as applying each coat to the joints. Conceal flanges
of gypsum board cornerbead by at least two coats of compound. The
first coat should be all-purpose compound. The second coat can be

all-purpose or topping compound feathered out approximately 9 in.
(229 mm) on both sides of the exposed metal nose.

In cold weather (outside temperature below 50°F or 10°C), maintain
temperatures within the building at a minimum of 50°F (10°C), day and
night, during joint finishing. Provide adequate ventilation to eliminate
excess moisture. Wet or damp conditions will slow the drying
process. Subsequently, 24 hours drying time between coats may not
be sufficient. Adequate drying time is essential to prevent unwanted
conditions, such as cracks, from delayed shrinkage.

Decoration

Before applying paint, wall covering or other decorating materials, all
areas must be thoroughly dry and dust free and treated with a coat of
good-quality, high solids, flat latex primer.

Selection of a paint to provide desired finish characteristics is the

responsibility of the architect or contractor.

Refer to the Gypsum Association, GA-214,

Recommended Specification

for Levels of Gypsum Board Finish

, to determine the level of finishing

needed to assure a surface properly prepared to accept the desired
decoration.
