| This topic is available here on The Repair-Place forum | While I was in Home Depot, I noticed there are several different kinds of joint compound. There is light weight, fast setting, and regular.
Which one should I use? | |
| There are different types for different reasons.
There is the regular premixed joint compound that is used for general mud and tape jobs. It usually has a green cover. Sheetrock® All-Purpose Joint Compound, by USG is one brand. It is for embedding drywall joint tape and for filling, leveling and finishing coats, over drywall joints, fasteners, corner bead and trim. This type compound features excellent slip, good crack resistance, and low shrinkage for ease in joint finishing. Excellent bonding properties are retained even under humid job conditions. Also ideal for skim coating drywall, repairing small cracks and holes in drywall and plaster surfaces, and simple hand-applied texturing.
There is light weight premixed joint compound that is also used for general mud and tape jobs. It usually has a blue cover. Sheetrock® Plus 3™ Lightweight All-Purpose Joint Compound, by USG is one brand. It is used for embedding drywall joint tape and for filling, leveling, and finishing coats over drywall joints, fasteners, corner bead, and trim. Offers all the benefits of a conventional-weight all purpose compound plus 3 key advantages: up to 35% less weight, lower shrinkage, and exceptional ease of sanding. Compound features superior ease of handling, good crack resistance, and excellent adhesion. Designed to provide low shrinkage, usually requires only two coats over metal, such as corner beads and fasteners, saving time and money. Also can be used for repairing small cracks and holes in drywall and plaster surfaces and for simple hand-applied texturing. Not recommended for skim coating drywall."
Then there is the setting types. These come in a bag and are mixed with water. Sheetrock® Easy Sand™ Lightweight Setting-Type Joint Compound, by USG is one brand Durabond is another. These chemically-setting powder products mix easily with water and are available in a choice of setting-times to meet varying job requirements: 20, 45, 90 and 120 minute setting ranges. Allow one-day drywall joint finishing with next day decoration. After a coat has set (hardened), another coat may be applied. No need to wait for each coat to dry completely. Weighs up to 25% less than conventional-weight compounds for easy handling and application. Provides sanding ease similar to a ready-mixed all purpose joint compound. Offers excellent bond, very low shrinkage, humidity resistance, and check-crack resistance. Ideal for patching drywall and plaster surfaces.
