Yes. Joint compounds produced by other companies can be used with good results on Georgia-Pacific gypsum board provided these compounds meet or exceed ASTM C 475 product standards. However, do not mix compounds produced by different companies. Use the same brand of compound for all coats. Otherwise, there may be a reaction between the proprietary ingredients of each brand.

The joint compound should be mixed thoroughly before each use. If the joint compound pail was not closed properly after the previous use, a small amount of water should be added prior to mixing. Always use clean mud pans, taping knives and other tools.

While this may appear to be a funny question, it deserves a serious and professional answer. Even though our joint compound is non-toxic, take the pet to a veterinarian. You or the vet can call our Environmental Safety department at 404-652-5119 for information. Information about safety and first aid measures is also available in the Material Safety Data Sheet (PDF 135KB/7pgs) for All-purpose Ready-Mix joint compounds.

In addition to finishing joints, joint compounds are used to skim coat or texture gypsum board surfaces. Water or latex based paint can be added to joint compound to texture the board surface. Refer to The Wallworks Guide (PDF:1.7MB/8pgs). Joint compounds also are used as an adhesive to laminate gypsum board to gypsum board or interior concrete masonry wall surfaces.

There are two different types of joint compounds; drying and setting types. Drying type compounds are composed of limestone and binder. These compounds must dry out completely before the binder becomes effective. Setting compounds work well with fiberglass mesh tape. ToughRock® 90, the Georgia-Pacific Gypsum brand of setting compound, is recommended for skim coating DensShield® Tile Backer and DensGlass® Sheathing (see literature for application recommendations).

First, do not allow Ready-Mix joint compound to freeze. However, in the event that the compound does freeze, it should be allowed to thaw completely. Do not force the thawing cycle with heaters, heat guns, etc. Simply place the bucket in a warmer environment. Once thawed, it should be mixed thoroughly. Then try it out on a small area to test its working characteristics. Multiple freeze and thaw cycles will have a negative impact on workability and may cause the compound to form small lumps. In this case, it should be discarded.
