Enviro 200P Ultra is a water-based, urethane-modified crosslinked copolymer waterproofing membrane for internal wet areas beneath tiles or other suitable protective finishes. Classified as Class III under AS/NZS 4858:2004, it provides a highly flexible, seamless waterproof barrier for bathrooms, showers, laundries, kitchens and other internal wet-area floors and walls. The manufacturer also identifies selected water tank applications; suitability for a particular tank service must be confirmed before specification.
Key Features
Class III highly flexible membrane with 1,400% reported elongation (AS 1145.3).
Water-based, low-VOC formulation (40 g/L) with urethane modification to resist re-emulsification.
Excellent crack-bridging characteristics and vertical hold-up.
Brush, roller or squeegee application; reinforcing fabric is not generally required across the membrane field, but specified bond-breaking and joint detailing remain essential.
For concealed use beneath tiles, screeds or other suitable protective finishes; not suitable as an exposed or UV-stable coating.
Coverage and Film Thickness – 15 L Pail
Internal floors: 2 coats at approximately 0.75 L/m² per coat (1.5 L/m² total); approximately 10 m² per pail for a finished dry film thickness (DFT) of 1.0 mm.
Internal walls: 1 coat at approximately 1.0 L/m²; approximately 15 m² per pail for a finished DFT of 0.6 mm.
Actual coverage depends on substrate condition, profile and application losses. Verify wet film thickness during application.
Preparation and ApplicationPrepare a sound, clean, dry substrate free from laitance and contaminants. New concrete must be cured at least 28 days; renders and screeds at least 7 days, with the substrate moisture limits specified in the TDS. Select Enviro Prime WB or Enviro Shield primer as directed for the substrate. Detail corners, joints and penetrations using the specified Enviro Flex sealant and Enviro Cloth Tape Black, or Enviro Joint Band where nominated. Mechanically mix at low speed (<200 rpm) before application.
Drying and Curing (23°C / 50% RH)
Recoat: 3–4 hours minimum.
Direct tiling: at least 24 hours after the final coat, once sufficiently dry.
Full cure: 7 days.
Flood testing: no separate early flood-test interval is nominated in the supplied TDS. Allow full cure and obtain manufacturer confirmation for the proposed test conditions.
Maximum recoat interval: 72 hours; beyond this, cleaning and specified repriming are required.
Application temperature must be 10–35°C with relative humidity no greater than 85%. Drying times increase under cool, humid or poorly ventilated conditions.Important: This is not an exposed trafficable or UV-stable membrane. Follow the current Envirosystems TDS and applicable NCC and Australian Standards requirements for the complete waterproofing system.
