Mineral Primer for Lime: What It Does and When to Use It

Quick answer

Use Mineral Primer for Lime on standard, absorbent surfaces before applying Color Atelier Limewash Paint or Plaster. Choose Bonding Primer for Plaster when your substrate is synthetic, unstable, or non-absorbent.

Decision rules for choosing your primer

• Surface type: Standard, absorbent surfaces like bare brick, stone, or old lime plaster → use Mineral Primer for Lime.
• Substrate condition: Synthetic, glossy, or unstable substrates (e.g., drywall, painted walls, or non-absorbent surfaces) → use Bonding Primer for Plaster.
• Finish type: Applying Color Atelier Limewash Paint or Plaster → Mineral Primer for Lime is the standard match.
• High-adhesion need: If the surface is questionable or you want extra insurance against peeling → Bonding Primer for Plaster is the better choice. When in doubt, Bonding Primer offers more grip on tricky surfaces.

Primers for lime and plaster

• Mineral Primer for Lime: Color Atelier’s Mineral Primer is a high-solids, mineral-based primer designed for use with Color Atelier Limewash Paint and Plaster. It creates an even base that promotes uniform absorption, reducing the chance of patchy or uneven color on interior and exterior walls.

  

• Bonding Primer for Plaster: Color Atelier’s Bonding Primer is a mineral-based, high-solids primer formulated with aggregates for use with Color Atelier’s plasters.
