High Density Setting Compounds are recommended for heavy fills or when exceptional bond is necessary. Once dry the product is not sandable. It is specially formulated to harden with very little shrinkage. This enables gypsum wallboard joints to be taped and first coated with High Density, and once set, the joints can be finished with All–Purpose Compound — all in the same day.

Joint Finishing:

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