Technical Information

Installation

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. 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 2-1/2" (64 mm) wide. Center mesh tape over joint and embed with a broad knife. Allow to set, as per product specifications on the package.

PRECAUTIONS:

• 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.

SANDING: Allow to dry for 24 hours before sanding. Use 120 grit sand-paper and a hand or pole sander. Do not sand the surface of the wallboard paper.
