Yes. SHEETROCK® Brand DURABOND®, SHEETROCK® Brand EASY SAND™, SHEETROCK® Brand All Purpose, and SHEETROCK® Brand Joint Taping Compounds provide the best performance bonding gypsum panels.

 No. When using fiberglass tape, only setting-type joint compounds like SHEETROCK® Brand DURABOND® and SHEETROCK® Brand EASY SAND™ should be used for the first coat over the tape. Ready-mixed drying-type compounds can be used for subsequent finishing coats.

There are various products in the market which, when mixed with joint compounds, claim to improve various performance attributes of joint compounds. USG does not endorse the use of additives in USG joint compounds for the following reasons:

An additive can adversely affect the unique balance of the many performance attributes each joint compound has been formulated to provide.

It is virtually impossible for an additive manufacturer to know if their additive is compatible at all times with all of USG´s product formulations.

USG has no control over the manufacture and quality of additives manufactured by others.

Note - For taping and finishing joints, water can be added as necessary. USG recommends adding water in increments of a half-pint to avoid over thinning. See USG Technical Information Sheet J1716 for more information.

No. SHEETROCK® Brand Setting-Type Joint Compounds (DURABOND® and EASY SAND™) are recommended to treat joints in exterior gypsum ceiling board.

Under conditions of a temperature of 70° and 70% humidity, joint compound should dry in about 24 hours. Higher humidity and/or lower temperatures will slow drying time.

Over time stains settle into a wall or ceiling. When that area is retextured the stains photograph through causing a yellowing or browning effect. The best way to prevent staining is to apply a stain blocker, primer, and sealer.

Yes. Joint compounds can be used over each other but should never be mixed with each other.

Joint compound does not have a fire rating by itself, but does meet ASTM C475. When fire testing a wall the fire rating is not for individual products, but for all the system components together. USG Joint Compounds are used in numerous fire-tested assemblies. These are outlined in USG Publication SA100 Construction Selector.

The maximum gap should not exceed 1/8 of an inch.

Yes. Each coat must be completely dry before applying the next.

SHEETROCK® Brand DURABOND™ and EASY SAND™ are the best products to use for repairing cracks. If you want to use a ready-mixed joint compound, SHEETROCK® Brand All Purpose Joint Compound works well.

Under conditions of 70° and 70% humidity, USG Joint Compound should dry in about 24 hours. Higher humidity and/or lower temperatures will slow drying time.

Blistering joints are the result of not having enough joint compound under the tape. The best way to repair blistering joints is to open up blistered area by slitting the tape. Fill the cut with joint compound and press tape back in place with knife blade.

Over time stains settle into a wall or ceiling. When that area is redecorated with a water based texture, stains from smoke, grease, water, soot, etc. may migrate through the new texture causing a yellowing or browning effect. The best way to prevent staining is to apply a stain blocker and primer/sealer before applying the new texture.
