Dry porous substrates must be primed with WPA SB solventbased primer or WPA 460 two-part water based primer.
Damp substrates with a RH of <75% must be primed with WPA 460 two-part epoxy primer. Substrates with an RH >75% must be primer with WPA 560 Moisture Seal.
Lightweight structural fibre cement sheeting must be primed with WPA 460 or WPA 560 Moisture Seal.
WPA 992 is a thixotropic, single-pack, liquid-applied polyurethane waterproofing membrane developed for both above- and below-ground applications. Once cured, it forms a seamless, durable, and elastomeric barrier that delivers reliable protection against water ingress.
This high-performance membrane is tar- and bitumen-free, offers excellent adhesion to primed substrates, and is permanently flexible, making it ideal for projects requiring long-term waterproofing integrity.
Internal wet areas (bathrooms, laundries)
Balconies and decks
Retaining walls*

*Use with WPA 992 Root Inhibitor Additive for retaining walls and planter boxes.
✅ Class III membrane (AS/NZS 4858) & Class II membrane (AS 4654.1) compliant
✅ Seamless waterproof barrier – tough and durable
✅ One-part, liquid-applied formulation – easy to use
✅ Fast drying for efficient application
✅ Permanently flexible – resists cracking and movement
✅ Excellent adhesion to most suitably primed substrates
✅ Good chemical resistance
✅ Tar and bitumen free – safe and clean performance
Do not apply WPA 992:
• Over damp, wet or contaminated substrates
• If it is raining or if rain is imminent
• Directly over any existing coatings
• Directly to particle board flooring (ceramic tile underlay must be installed)
• As a wearing surface for foot or vehicle traffic
• As an exposed membrane
• In swimming pools, spas, tanks or ponds
• Where the surface temperature is below 10°C or greater
than 35°C
• To areas subject to negative hydrostatic pressure or rising
damp
• Do not install tiles directly over WPA 992, a engineered self supporting screed must be installed.
