Using Drywall Adhesives on Home Improvement Projects

When drywall installation is part of a home improvement project, several types of adhesives are available that can be worked with. Each adhesive has unique aspects and applications.

One type is designed for installing drywall panels directly on wood framing. It is found packed in tubes and is used in a cartridge gun similar to the kind used for caulking compound. The tip of the tube is cut wide enough to allow a 1/4" bead to flow.

Another type of drywall adhesive is formulated for use on metal stud systems often found in commercial projects, though some homes use this type in more special applications. There is yet another type that is designed for use on either wood or metal framing.

Contact adhesives are commonly used in a wide variety of installations such as when two sheets of drywall are fastened together for better sound control, or for a higher fire rating. Contact adhesives are also used when drywall is placed over an existing plaster wall.

Solvent-based adhesives are utilized in varying interior applications. They provide good adhesive and bonding qualities but will require greater care when positioning and placing the drywall sheet against its intended surface. Solvent-based adhesives also produce flammable vapors which need proper ventilation.

Joint compound is most often used to seal and smooth adjoining sheets of drywall, but it can also be used for laminating two sheets together in a double-layer application. This method of adhesion, unlike contact adhesives, requires as long as 24 hours to dry and temporary clamping must be applied until the compound has set.

Water-based adhesives, which are used for many drywall installation applications, also require this amount of drying time and should be fastened temporarily until properly set. Since the adhesive is water-based, the hazards associated with solvent-based adhesives need not be a consideration. It is important to note, however, that water-based adhesives should not be used in areas where moisture is present. These adhesives are easily removed from tools and other equipment simply by using water.

The type of adhesive selected for the job depends on the type of application and the desired completion time. Check with your local hardware store or home center adhesives represenative for the right drywall adhesive for your home improvement project.

Remember, always work safely.
