Primers + Surface Preparation

Primers for limewash and mineral paint

Mineral finishes bond with the wall instead of sitting on top of it, so the surface underneath matters. Choose the primer by what you see on your wall:

• Under limewash, for the Cloud Effect: Primer Plus, an air-lime primer that evens absorption.
• Absorbent drywall, plaster or patches: Primer White L44, diluted 1:1, one coat. The recommended primer before GrafGen™.
• Smooth or non-porous surfaces: Primer Contac, a bonding bridge for skim coats and mineral finishes.
• White salt stains (efflorescence): Neutralysalt Primer, after brushing the salts off dry.
• Chalky, crumbling or weak mineral surfaces: MinerGen, a potassium silicate consolidating primer that penetrates without forming a film.
• Metal, wood and mixed surfaces: All Terrain 4x4, a water-based multi-surface primer.
