Additional Information


Mixing Process

  • Always use clean tools.
  • Do not mix with residue of previously used compounds.
  • Inclusion of such materials will impair the performance of this product and void the product warranty.
  • USG Boral Maxi Skim™ 88 may appear thick in the pail. Before adding water, lightly mix the product and test its application. If required, add water to achieve the desired consistency.
  • Caution: Avoid over-thinning when adding water as this may cause cracking and excessive shrinkage.
  • If liquid has separated from the compound, stir carefully to restore consistency.
  • Caution: Do not overmix. Overmixing can introduce air bubbles, which can create surface imperfections.

Application Process

  • Apply USG Boral Maxi Skim™ 88 in accordance with the manufacturer’s recommendations.
  • Maintain a surface temperature above 13 °C on the working area during wall and ceiling finishing.
  • Provide adequate ventilation to ensure proper drying.
  • Wall and ceiling surfaces must be dry and free from dust, dry salts, oil, grease, or other sources of contamination. Smooth, glossy surfaces must be sanded and treated with a bonding agent.
  • Lay the first coat of USG Boral Maxi Skim™ 88 to a minimum thickness of 2mm using a trowel, and grade to a flat, smooth surface. If an additional coat is required, allow the first coat to dry before applying the second coat.
  • Touch up remaining uneven area with USG Boral Maxi Skim™ 88 where required. Allow to fully dry before sanding.
  • When sanding, use fine sandpaper (220 grit or higher) to avoid scratching the dry surface.
  • Thoroughly clean all tools and equipment after use.

NOTE: All surfaces including applied joint compound require light sanding before painting.
