One kit to waterproof a bathroom with ACTFLEX 906 WPU. Class III on both standards, 8 to 10 m² from the 20 kg pail.
This kit is built around ACTFLEX 906 WPU, a single pack, water based polyurethane membrane tested Class III to both AS/NZS 4858 and AS 4654.1. It comes with the primer, sealant, tap collars and the tools to roll it on.
What's in the kit
- ACTFLEX 906 WPU, 20 kg pail
- ACTFLEX 500 NP PRIMER, 5 L
- ACTFLEX MS PRO joint sealant, 600 mL sausage
- SUPERFLEX tap collars, 3
- Forspec 600 mL sausage gun, 230 mm roller frame, 6 roller covers and 2 wood brushes
Where to use it
- Bathrooms, showers and laundries under tiles or screed (AS 3740)
- Walls and floors on prepared concrete, masonry, cured render and screed, and wet area fibre cement sheet
- Junctions get an MS PRO cove fillet. Taps and pipes get a SUPERFLEX collar
- Primer first. The 500 NP PRIMER in the kit is for dense, smooth or non-porous substrates. For porous concrete, masonry, render and fibre cement the 906 WPU TDS specifies ACTFLEX 200
Why buy the kit
- Class III to AS/NZS 4858 and AS 4654.1, NATA accredited reports. Over 500% elongation

Technical overview
Key applications
- Internal wet areas - bathrooms, showers, laundries - beneath approved tiled or screeded finishes, per AS 3740
- Wall and floor waterproofing on prepared and primed concrete, masonry, cured renders and screeds
- Wet-area-grade fibre cement wall sheeting and approved compressed fibre cement flooring
- Wall-to-floor and wall-to-wall junctions, detailed with an ACTFLEX MS PRO cove fillet
- Tap and pipe penetrations in bathrooms, laundries and kitchens, detailed with a FORSPEC SUPERFLEX COLLAR
- Priming of dense, smooth or non-porous substrates with ACTFLEX 500 NP PRIMER
Surface suitability
- Concrete (structurally sound, normally at least 28 days old, mechanically prepared to a clean open texture, moisture reading below 4.5%)
- Masonry and blockwork (prepared, clean, dry and free of bond-inhibiting contaminants)
- Cementitious renders and screeds (fully cured)
- Wet-area-grade fibre cement wall sheeting (installed per the sheet manufacturer and the applicable Australian Standard)
- Approved compressed fibre cement flooring
- Dense, smooth or non-porous substrates (compatibility confirmation required, primed with the ACTFLEX 500 NP PRIMER supplied in the kit)
The membrane governs the limits of this kit. ACTFLEX 906 WPU is not for permanent exposure to direct sunlight; cover with the approved finish after full cure or topcoat with ACTFLEX 101 UV where UV exposure will remain. Not for planter boxes, swimming pools, ponds, tanks or other continuously immersed applications, or where continuous or repeated chlorine exposure is expected. Not a vapour barrier and not for negative hydrostatic pressure. Not an exposed trafficable wearing surface; light foot traffic after full cure for inspection and installation access only. Do not apply over particleboard, platform or yellow-tongue flooring, chipboard, asbestos-containing materials, timber or unverified proprietary sheet products. Do not bridge active cracks or movement joints with continuous membrane. Do not apply where the quantitative concrete moisture reading is 4.5% or higher without the two-coat ACTFLEX EP250 moisture-control system, which is not in this kit. Apply only between 10-26C ambient and substrate. Do not dilute. Not approved for potable-water contact. ACTFLEX 906 WPU is a hazardous chemical: it causes skin irritation and serious eye damage, may cause respiratory irritation and is toxic to aquatic life with long-lasting effects. ACTFLEX 500 NP PRIMER is not a waterproofing membrane and not a moisture barrier, and the SUPERFLEX collar is a detailing component that must be embedded within the membrane, never used stand-alone.

Frequently asked questions
-
What's in the Standard Bathroom Waterproofing Starter Kit?
CompatibilityThe Standard Bathroom Waterproofing Kit contains a complete system for a single bathroom: primer (ACTFLEX 200 or similar), liquid membrane (ACTFLEX 906 WPU), reinforcement mesh tape (MESHTAPE or AT-MESH), application tools (brushes, roller, frame), and detailing accessories.
-
What area does it cover?
PerformanceThe Standard kit is sized for a typical 5-8 m² Australian bathroom - shower floor, hob, splashback zones, and floor-to-wall junctions. For larger bathrooms, ensuites, or multiple wet areas, choose the Premium kit or supplement with extra membrane.
-
Can a DIY-er use this kit?
InstallationYes. The system is professional-grade but the kit format is designed to be DIY-friendly for licensed waterproofers or experienced renovators. Note: Australian states have licensing requirements for paid waterproofing work - check your local regulations before working for others.
-
What additional materials do I need?
CompatibilityAside from the kit, you'll need: silicone sealant for perimeter joints (ACTFLEX 75FC or MS PRO), the substrate (which should be sound and prepared per AS3740), and the tile adhesive/tiles for finishing.
-
Will the finished waterproofing meet AS3740:2021?
ComplianceThe kit's ACTFLEX 906 WPU membrane is Class III certified and the system is compliant with AS3740:2021 when installed per the supplied instructions. Get your work inspected by a building surveyor where required by local council.
