Lite Sand Setting Compounds are lightweight, sandable, chemically setting powders used to pre-fill joints, embed joint tape and conceal joints, fasteners and trim accessories on gypsum wallboard. They can also be used for interior patching and repair. They are ideal for heavy fills because they are specially formulated to harden with very little shrinkage in a prescribed time frame. Setting times are available from 20 minutes to 90 minutes.

Joint Finishing:

  • Wallboard joints are normally finished using three coats of compound; the first to embed the tape; the second to cover the tape, and the third to finish the joint. CertainTeed Sandable Setting-Type Compound can be used for the first and second coats. Although the third coat is typically done with a ready-mix product, the Sandable Setting-Type Compounds can be used as well. For joint reinforcement the use of Fibreglass mesh tape is recommended. Apply the first coat to the joint in a band about 64 mm (2-1/2") wide. Center CertainTeed mesh tape over joint and embed with a broad knife. Allow to set, as per product specifications on the package.


  • These compounds generate heat as they harden. Keep the compound away from exposed skin during the hardening process to prevent burns. Do not apply or re-mix after it has started to set. Compound must be applied to a clean, dry surface. Use is limited for above grade applications. When mixing and/or dry sanding, wear safety glasses and dust mask approved by NIOSH/MSHA. Keep out of reach of children.


  • Allow to dry before sanding. Use 120 grit sand-paper and a hand or pole sander. Do not sand the surface of the wallboard paper.
