- High adhesion to dense, smooth substrates
- Internal and external, horizontal and vertical use
- Apply by brush, roller or airless spray
- Excellent water and alkali resistance
- Suitable beneath WMA acrylic, latex and polyurethane membranes
Application Guide
- Ensure the substrate is structurally sound, dry, smooth and free from loose material, old coatings, dust and bond-breaking contaminants. Repair holes and non-structural cracks and remove unsound coatings. Apply Premium Prime at full strength by brush, roller or airless spray to achieve complete coverage without pinholes. Do not dilute. Allow approximately 20–50 minutes at temperatures above 15°C before applying the compatible WMA membrane. Cooler temperatures or higher humidity will extend drying time. Do not use over old solvent-based or bituminous coatings, or where rising moisture or negative hydrostatic pressure is present.
