ProForm 68371613 Multi-Use Joint Compound
DESCRIPTION
ProForm® Multi-Use Joint Compound is a vinyl base ready mix joint compound formulated especially for professional drywall contractors and finishers. It may be used directly from the container.
BASIC USES
Applications
Use for all phases of finishing, from embedding joint tape to final coats.
Advantages
- Weighs up to 20% less than standard ready mix.
- Shrinks less than all-purpose formula.
- Provides excellent bond.
- Lessens pocking and pin holing.
- Mold resistant.
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 the Consumer Product Safety Standards.
General
Install Multi-Use Joint Compound according to the methods described in “Applicable Standards and References” and as indicated in this section. Mix thoroughly before using or thinning. If thinner consistency is desired, add clean, drinkable water in 4 to 8 oz. increments not to exceed gallon weight and remix. Excess water may cause product failure. Do not mix with other joint compounds (wet or dry) or other materials.
Use directly from the container for treating fasteners and corner beads or for taping and finishing joints. Apply a uniformly thin layer of joint compound over the joint approximately 4″ (102 mm) wide. Then center the tape over the joint and embed it 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 embed 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″ (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 1the edges feathered approximately 3″ (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 corner bead with at least two coats of compound. The first coat should be an all-purpose compound. The second coat can be all-purpose or topping compound feathered out approximately 9″ (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 conditions will slow the drying process. Subsequently, 24 hours of 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. The selection of paint to provide the desired finish characteristics is the responsibility of the architect or contractor. Refer to the Gypsum Association, GA-214, Levels of Finish for Gypsum Panel Products, to determine the level of finishing needed to ensure a surface is properly prepared to accept the desired decoration.
Sustainable Design
Achieves UL GREENGUARD Certification for low chemical emissions into indoor air during product usage. For more information, visit: ul.com/gg. (Continued on page 3)
TECHNICAL DATA
The pail contains 30% post-consumer recycled (PCR) plastic.
Approximate Drying Times
The chart above is a helpful guide in determining the approximate drying times for joint compounds under a variety of humidity/temperature conditions. The shaded area is below the minimum application temperature requirement of 50°F (10°C) and is not recommended for the application of the joint compound.

LIMITATIONS
Storage
- Shelf life up to 9 months under good storage conditions (see production code date).
- Maintain temperature at a minimum of 50°F (10°C) and protect the container from exposure to extreme heat and sunlight to prevent spoilage and freezing.
Frozen Ready Mix
- Allow material to thaw at room temperature for at least 24 hours.
- Once thawed, turn the container upside-down for at least 15 minutes.
- Turn the pail right side up, remove the lid, and immediately remix with an electric drill.
- The ready mix should be lump-free and ready to use within 1 minute.
- Discard an all-ready mix that does not remix to a lump-free consistency.
Stacking
- Do not stack ready mix pails or cartons more than two pallets in height.
General
- Do not overthink the ready mix.
- Do not overmix with an electric drill. This can cause undesirable changes in viscosity and the finished surface appearance.
HANDLING AND PROJECT CONDITIONS
Environmental Conditions
Varying weather conditions can impact both the quality and appearance of taped gypsum board joints. Relative humidity, plus temperature, will affect the working characteristics of all joint compounds. Minimize the potential for finishing and decorating problems when temperature, humidity, and airflow remain constant and as close to occupancy environmental conditions as possible. Continuously maintain a minimum temperature of 50°F (10°C) for 48 hours before and
throughout the finishing process until applied materials are thoroughly dry.
For example, cool, wet weather will slow down the drying process while hot, dry weather hastens the drying process. Exposure to winds, breezes or drafts while drying can also affect the performance of joint compounds. Typical problems from improper drying can be cracking, excessive shrinkage, ridging, beading, banding, or bond failure. A further explanation of these conditions is outlined in the “Problems and Solutions” section of the ProForm® Finishing Products Construction Guide. Always take proper precautions at the jobsite to minimize the adverse effects of weather on drying.
These precautions will ultimately reduce the application time and expense from callbacks and rework. Planning And Prevention: Mold And Mildew Resistance Planning and prevention is the most effective way to avert the growth of mold or mildew. Deliver gypsum board and finishing products to a jobsite as near to the time they will be used as possible. Once delivered to a jobsite, place gypsum board under cover immediately and properly protect it. Do not expose it to outside elements, such as rain, snow, or other high moisture conditions. If building materials get wet from any moisture source, identify and correct that source.
If mold or mildew growth occurs, or if you suspect it might occur due to environmental conditions and moisture, either attempt to dry and clean the affected areas or replace the affected materials. If you do not have the training or experience to recognize and make the proper decisions about repair or removal, consult a professional. A proper evaluation must be made.
No material can be considered “mold-proof,” nor is it certain that any material will resist mold or mildew indefinitely. When used in conjunction with good design, handling, and construction practices, the ProForm joint compound can provide increased mold resistance. As with any building material, avoid water exposure during handling, storage, installation, and after installation is complete. This is the best way to avoid the formation of mold or mildew. 110685 REV. 04 24 National Gypsum Company is the exclusive service provider for products manufactured by ProForm Finishing Products, LLC.
