What substrates does ACTFLEX 929 HV bond to?

929 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.

What thickness should I apply?

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.

How long until I can tile over it?

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.

Is 929 HV Australian standards certified?

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.

What is the elongation and is it root-resistant?

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.

How to Use

Apply by roller or brush in a minimum of two coats at approx. 0.7 mm wet film each to a minimum 1.2 mm total DFT, each coat at right angles to the lastConfirm the substrate is structurally sound, clean, dry and free of laitance, dust, oils, grease, curing compounds, release agents, coatings, rust, efflorescence and loose material - application constitutes acceptance of the substrate
Confirm concrete is cured a minimum of 28 days with a wood-trowel finish, and renders and screeds a minimum of 7 days
Reinstate damaged concrete with FORBUILD 100 or FORCRETE 100, cured before priming
Remove high points and protrusions that could pierce the membrane
Confirm falls - minimum 1:80 and maximum 1:50 to the floor waste internally, minimum 1:100 externally
Prime with ACTFLEX EP250 on prepared concrete and porous cementitious substrates, ACTFLEX MB200 where elevated substrate moisture is identified, or ACTFLEX 700 PU PRIMER on porous substrates where no moisture barrier is required
Apply the membrane within the primer's overcoat window
Treat static cracks under 2 mm with the approved crack-repair method and centre ACTFLEX SA TAPE over the crack, ends overlapped a minimum of 50 mm
Fill static cracks 2 mm and over, and sealed junctions, with ACTFLEX MS PRO and the approved bond-breaker detail, cured to membrane-ready
Form a continuous ACTFLEX MS PRO fillet at wall and floor junctions, drains and penetrations - nominal 12 mm internally, 15 mm x 15 mm externally - tooled smooth and cured
Seal penetrations with the primer, sealant, reinforcement and membrane detail together, then probe and inspect every detail
Stir gently at low speed to a uniform consistency without whipping air in, keeping the pail sealed except when drawing material, and never dilute
Apply by roller or brush in a minimum of two uniform coats at approx. 0.7 mm wet film each to a minimum 1.2 mm total DFT, each coat at right angles to the last
Verify wet film with a gauge on every coat and never exceed 1.5 mm WFT in a single pass
Recoat after 4-6 hours at 25C, 50% RH once the preceding coat is tack-free, and within a maximum of 24 hours
Protect the membrane from water, contamination, sharp objects and traffic throughout curing, and cover or protect from UV immediately after full cure
Allow 48 hours full cure after the final coat, then flood test to a minimum depth of 50 mm at the highest point for 24 hours
Install a 200 micron polyethylene slip sheet, then the screed at a minimum 40 mm per AS 3958.1, or 35 mm minimum using FORSPEC SCREEDX
Tile to the screed in accordance with AS 3958.1, never direct to the membrane

Technical overview

ACTFLEX 929 HV is a Class III, non-sagging, moisture-cured polyurethane waterproofing membrane for internal and external under-tile and non-exposed applications where toughness, chemical resistance and root resistance govern selection. It is independently certified Class III under both AS/NZS 4858:2004 (XTecGen Report 0242-5) and AS 4654.1-2012 (XTecGen Report 0242-7), with 547% certified control elongation and cyclic movement, water, bleach and detergent immersion and heat-ageing passes. Testing was carried out by XTec Gen Pty Ltd, accredited for compliance with ISO/IEC 17025, on a two-coat 0.7 mm build to a 1.2 mm dry film. It complies as a Class III membrane within a compliant system to AS 3740:2021, and is limited to non-exposed applications within an approved system under AS 4654.2.

Key applications

Internal and external wet areas beneath protected finishes, per AS 3740
Roof terraces and roofs, non-exposed, beneath approved coverings, per AS 4654.2
Planter boxes and above-ground pits with non-aggressive root systems only
Retaining walls and below-grade protected surfaces exposed to corrosive soils
Bridges, walkways, substations and parking decks beneath protection
Prepared concrete and metal surfaces
General waterproofing maintenance and repairs

Surface suitability

Concrete (cured a minimum of 28 days, wood-trowel finish)
Renders and screeds (cured a minimum of 7 days, wood-trowel finish)
Wet-area-grade fibre cement wall sheeting (minimum 6 mm)
Compressed fibre cement (minimum 15 mm)
Brickwork, blockwork and masonry
Metal surfaces (primed)

Not suitable for exposure to sunlight or UV - the membrane must be protected or covered immediately after full cure, and pedestal systems that leave it fully exposed require an ACTFLEX ATC or ACTFLEX ULTRA TC topcoat before pedestal installation. Direct adhesion of tiling to the cured membrane is not recommended - tiling is always to the screed per AS 3958.1, over a 200 micron polyethylene slip sheet. Allow full cure, a minimum of 48 hours at 25C and 50% RH, before tiling, backfilling, topping or immersion. Maintenance foot traffic only in uncovered internal areas such as plant rooms - not designed for daily traffic, piercing footwear or machinery. Root resistance is limited to non-aggressive root systems such as small garden trees, hedges and shrubs, not aggressive or invasive species. Not compatible with all silicone-based and bituminous surfaces and products. Not for constantly submerged applications such as pools and ponds, or chlorine environments. Not a vapour barrier and not designed to withstand negative-side hydrostatic pressure. Apply only to dry substrates, only between 10-26C, and never below 10C surface temperature. Do not dilute. Spray application is not approved.
