Sheetrock Midweight All-Purpose Joint Compound
Description

Sheetrock Midweight All-Purpose Joint Compound’s special vinyl formulation makes it ideal for embedding tape and for filling, levelling and finishing over gypsum panel joints, fasteners, bead and trim. It weights up to 15% less than conventional-weight compounds and provides lower shrinkage for metal bead, trim and fastener concealment.

Compared to conventional-weight compounds, it weighs up to 15% less, is easier working and sanding, and provides lower shrinkage for metal bead, trim, and fastener concealments.

Key Features
  • Ready-mixed convenience
  • Weighs up to 15% less than conventional-weight compounds
  • Easy working and sanding
  • Low shrinkage
  • Superior working qualities
  • Good crack-resistance
  • Excellent adhesion
  • Provides lower shrinkage than conventional-weight compounds for easier concealment of metal bead, trim, and fasteners
  • Facilitates working back, even under fast drying conditions, by providing more wet-edge life to prevent rolling and tearing of previously laid compound
  • Handling and applying is easier and faster
Scope of Use

A special vinyl formulation makes it an option for embedding tape as well as for filling, levelling, and finishing over plasterboard joints, fasteners, bead, and trim. Also excellent for skim-coating and hand-applying simple textures.

Limitations on Use

When used as a texture finish, it should be overpainted when dry. Not washable unpainted.

Prior to using any epoxy coating over any surface treated with joint compound, consult the epoxy coating manufacturer and follow manufacturer’s specific recommendations regarding the preparation or suitability of substrates for the epoxy coating. Many epoxy coatings exert significant shear stress on the substrate as the strong epoxy film shrinks while curing/drying.This stress can cause the bond of the joint compound to fail, resulting in delamination problems.

Protect container from freezing and extreme heat.

Statement of Building Code Compliance

Sheetrock Midweight All-Purpose Joint Compound complies with ASTM C475.
