Unpolished Stone

Natural stone is available in many forms and finishes. Porous types, like marble or limestone, offer the best adhesion. Before applying coatings, make sure the stone is thoroughly cleaned and well-dried.

Acrylics, oils, watercolors, and dry media can be applied directly to clean unpolished stone. If less absorbency is desired, apply a commercial masonry primer or conditioner.

Any of our Gesso & Grounds, Gels & Pastes, and most of our Fluid Mediums can be applied to alter the absorbency, durability, or texture of the surface.

For watercolors, we typically recommend applying Gesso followed by one of our three QoR Watercolor Grounds for a bright white absorptive surface.

For dry media like PanPastel, we recommend applying a textured ground or paste for improved tooth.

For protection, a suitable topcoat or varnish is recommended.
