Overview
SUPERGRIP is a water-based primer formulated to provide an enhanced adhesive key on water-based polymer coatings prior to application of plaster or plaster-based finishes. After Passive Purple or Passive Purple External / X has dried, apply Supergrip evenly with a roller to improve adhesion for dot & dab adhesive or plaster systems. Suitable for walls and ceilings. Mix thoroughly with a paddle mixer before use.

Application

• Minimum application temperature: +5°C.
• Apply between +5°C and +35°C by roller or low-pressure sprayer.
• Apply one layer: approximately 100–150 g/m².
• Do not apply in direct sunlight.
• Allow to dry before applying dot & dab adhesive or plaster-based products.
• Clean tools with water.
