ArmourCoat AntiCrack is a fiber and resin reinforced gypsum skim-coat plaster which resists cracking at board joints and significantly improves the impact resistance and durability of drywall construction.

When applied over a drywall surface, ArmourCoat AntiCrack exhibits outstanding tensile strength that has been proven to significantly reduce any movement or cracking between separate boards. Its high compressive strength provides a tough and durable background for all ArmourCoat finishes.

The application of AntiCrack will significantly improve resistance to cracking, but will not prevent cracking on a finished substrate due to structural movement. Use only on dry interior areas.

Product Features

• Significantly improves the impact resistance and durability of drywall construction to provide a strong foundation for Armourcoat finishes
• Resists cracking at board joints due to the high tensile strength of the product
• Anchors beads, stop beads, shadow gap beads, any sort of reinforcement and finishing bead details far better than screws and jointing compound
• Much higher impact strength than plasterboard or jointing compound
• Enables substrates to be true to the high specification required for polished plaster – eliminates flaring around beads
• No taping or jointing required except where code designates a Level 1 drywall finish
• Non-combustible as supplied or when applied

Coverage Rates

• Supplied in 25kg bags = 60 feet2 at thickness of 0.16 inch Minimum thickness = 0.13 inch

Suitable Substrates

• AntiCrack is suitable for application directly to unsealed drywall and to fresh gypsum basecoat plasters such as the Armourcoat Squash Court Basecoat or other weaker readily available basecoat plasters
• AntiCrack can be used in conjunction with galvanized, powder coated, stainless steel and plastic beads. Untreated aluminum beads must be treated with an aluminum primer prior to application otherwise oxidization of the surface of the aluminum will occur
• AntiCrack is not suitable for external use
• AntiCrack is not suitable for use directly over MDF or plywood
