Uses
AQUAGARD™ M Clear Primer is used for all AQUAGARD™ M grade and ULTRAURE™ membranes.
It may be applied to most rigid substrates used in construction including: concrete masonry, off-form concrete, in-situ concrete slabs and topping, shotcrete and cement render, light-weight foamed concrete, pre-cast concrete panels, compressed fibre cement sheet, metal and brick.
Features
- Strong physical bond to substrate
- Fast-drying PU resin system
- Coating is water-resistant and protects the structure in the event of interruption by wet weather
- Promotes adhesion even in cold weather
Substrate Preparation
Substrates must be structurally sound, smooth, clean and dry. Remove all dust, laitance, loose matter, oil, curing compound, 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.
Detailing
Detail according to NCC, and AS 4654.2 and AS 3740 requirements for external above ground and internal wet areas, respectively. Detailing should be completed before priming process starts.
Primer Application
AQUAGARD™ M Clear Primer is used for substrates with maximum moisture content of 5%. For moisture content less than 10%, use EPOCOTE™F100W Clear primer.
Apply one coat directly from container using brush, roller or spray. Allow primer coating to become tack-free before applying waterproof membrane. Only apply primer to substrate that will be membrane coated within 24 hours.
Apply the selected GCP polyurethane waterproofing product in strict accordance with product instructions.
Any primed area not coated with membrane within 24 hours must be first wiped with Xylene. As soon as xylene has dried, reprime with a light coat of AQUAGARD™ M Clear Primer at a rate of approximately 0.15kg/m2. Any applied primer that has not been coated with membrane within 72 hours of application, must be fully removed by diamond grinding and re-primed.
