ACTFLEX 929 HV is a Class III high performance, tough, root resistant, highly flexible polyurethane waterproofing membrane for use in internal and external under tile and non-exposed applications. ACTFLEX 929 HV is a single component membrane which cures by reaction with the atmospheric moisture to give a tough elastomeric waterproof membrane. It is supplied as a thixotropic liquid which is easily applied at the recommended thickness to both vertical and horizontal surfaces.
High-build single-component polyurethane waterproofing
Flexible, elastomeric film resistant to chemicals & roots
Compliant with AS3740:2021 & AS4654.2:2012 standards

Not suitable for sunlight/UV exposure — must be UV top-coated after cure. Not for direct tile adhesion (requires cement screed over the membrane). Not for constantly submerged applications (pools, ponds), chlorine environments or daily foot traffic. Limited root resistance — not for aggressive or deep-rooted species (large trees, palms). Not a vapour barrier; not for negative-side pressure.

Expert Technical929 HV bonds to concrete, render, fibre-cement sheet, masonry, and primed metal. Use ACTFLEX 600 Primer for porous substrates or 500 NP for non-porous; always confirm the primer pairing on the project's substrate.
Apply at 1.0mm DFT on walls, 1.2mm DFT on floors, and 1.5mm DFT in planter boxes - typically two coats at 90 degrees. Coverage is approximately 8-10 m² per 20kg pail at 1.2mm DFT.
929 HV is tack-free in 6 hours at 25°C and reaches full cure in 48 hours. Wait for full cure before tiling. Service temperature range is -10°C to +60°C once cured.
Yes. 929 HV is certified to AS3740:2021 (internal wet areas) and AS4654.2:2012 (external above-ground waterproofing) - Class III, the dual-standard premium PU membrane in the Forspec range.
929 HV delivers greater than 600% elongation at break and the cured film is root-resistant - making it suitable for planter boxes, green roofs, and applications subject to thermal cycling.
