Frequently Asked Questions
Ready to answer your product and installation questions
No material can be considered “mold-proof,” nor is it certain that any material will resist mold or mildew indefinitely. However, when used in conjunction with good design, handling, and construction practices, ProForm ready mix can provide increased mold resistance versus standard ready-mixed compounds. As with any building material, avoiding water exposure during handling, storage and installation and after installation is complete is the best way to avoid the formation of mold or mildew.
A good rule of thumb is to use nine gallons of ready mix for every 1000 sq ft of wallboard.
Ready mix pails or cartons should not be stacked more than two pallets high.
Nine months in good storage conditions. To prevent spoilage and freezing, maintain temperature at a minimum 50˚F (10˚C) and protect container from exposure to extreme heat and sunlight.
While not ideal, ProForm joint compound can go through up to 3 freeze-thaw cycles. Allow material to thaw at room temperature for at least 24 hours. When thawed, turn the container upside-down for at least 15 minutes. Turn pail right-side up, remove the lid and immediately remix with an electric drill. Ready mix should be lump-free and ready to use within 1 minute. Discard ready mix that does not remix to a lump-free consistency.
