Low-odour, heavy-duty-trafficable, polyurethane waterproofing membrane
A tough, resilient, two-part, polyurethane elastomer membrane producing long-life waterproof protection. It is a premium grade, low VOC elastomer using the latest technology to provide long-life, protective barriers to prestigious construction projects.
ULTRAURE™ A-80 Membrane and ULTRAURE™ A-80 Non-Slip Top Coat system are suitable for:
Substrates must be structurally sound, smooth, clean and dry. Remove all dust, laitance, loose matter, oils, curing compounds, form release agents, or other contaminants.
Concrete should have a minimum strength grade of 25 MPa, and be moist-cured as required by AS 3600. Minimum age of concrete at time of waterproofing application should be 14 -28 days depending on concrete thickness and GCP primer being used.
Use SILCOR® LM PU Sealant to fill joints, cracks, gaps and form angle fillets to internal corners or penetrations. Allow minimum 24 hours of curing for sealant.
Note
To inhibit pin-holes and seal porous surfaces where substrate moisture content is less than 5%, use one coat of AQUAGARD™ M Clear Primer at minimum 0.3 kg/m2 (0.3 litre/m2) and allow to dry tack free.
Use EPOCOTE™ F100W Clear to seal any damp or green concrete with moisture content less than 10%. Roughen PVC or stainless steel and wipe with Xylene before priming with EPOCOTE™ F100W Clear. Allow primer to dry tack free.
Measure each individual ULTRAURE™ A-80 Membrane Polyol and Isocyanate component accurately by weight into a clean container and mix thoroughly with an electric stirrer (300 rpm). Preferred material mixing and application condition is 10°C – 30°C and RH <85%.

Apply ULTRAURE™ A-80 membrane to primed and previously detailed areas, at or above the minimum required thickness in:
Required minimum thickness is dependent on installation area, type of use of the area, topping or membrane protection being employed and product warranty period required, and will be specified in the GCP project specification or architect’s specification. Where not specified, a minimum total Dry Film Thickness (DFT) of 1.5mm must be employed (total Wet Film Thickness (WFT) = 1.8mm/approximately 2.4kg/m2).
Test WFT during application using a WFT gauge and adjust applied thickness accordingly. Continue membrane to turn-ups by a minimum 100mm above finished surface level, or as detailed in project specification.
Where a high rating non-slip finish is required, apply membrane by a two stage process as follows:
Apply ULTRAURE™ A-80 Non-Slip Top Coat by roller or air-less spray system in 2 coats at minimum 0.3kg/m2 (minimum 0.15kg/m2 per coat). Allow 24 hours curing before opening area to foot traffic. Allow 5 days curing before allowing vehicle traffic.
Where non-slip aggregate broadcast has been employed, top coat requirement will increase significantly (0.6 to 0.9 kg/m2).
The finished ULTRAURE™ A-80 Membrane may be subjected to foot traffic 8 hours after installation but 5 days curing should be allowed before vehicles are driven over the surface.
If required for functional or aesthetic reasons, areas of ULTRAURETM A-80 Membrane may be covered with optional surfacing systems, after full curing.
Consult GCP Technical Service for details.
Use PROTECTOBOARD™ or RAPID-DRAIN™, followed by landscaping.
Use two layers of 0.2mm polyethylene slip-sheet under concrete toppings. Lay paving slabs supported on mortar bed.

Do not store product exposed to weather and sun. When kept in a cool, dry, protected area, sealed pails have a 12-month shelf life, but once opened may solidify within a few days.
Use MULTITEK™ Xylene before curing. Exercise care when using solvent, review all Material Safety Data Sheet (MSDS) before use.
In case of spills and accidents, refer to the MSDS of the products or when in doubt contact your local GCP representative.
Always wear protective clothing, gloves and protective goggles when handling chemical products.
For full information, consult the relevant MSDS.
Minimum applied thickness required is dependent on intended areas of application and warranty period desired. Consult your GCP sales representative or the GCP Technical Department for further information.
Cure rate is affected by temperature. High temperatures will cause rapid cure and reduced pot life. Low temperatures will significantly extend cure time. Information contained in this document does not cover all possible application scenarios or imply product suitability for an application.
Please contact your local GCP representative or the GCP Technical Department for further information.
GCP and contractors recognised by GCP as experienced in the application of GCP products will provide product warranties for individual projects. Product warranty periods offered are dependent on project details and complexity. Requests for very long product warranty periods may necessitate increased membrane thicknesses to ensure longevity. Contact your local GCP representative for further details.
