Encaustic Ground
Do not dilute. Apply two coats to sealed substrate.
Once dry, waxes may be applied directly to the prepared surface.
It is recommended a thin coat of untinted wax is applied first to the ground and fused into the surface using heat.
Encaustic Ground may also be used as a high absorbancy surface for water-colour techniques such as staining.
Langridge recommends application to inflexible supports such as timber or aluminium. If applied onto highly flexible supportthere is potential for cracking.
Drying time: 30-60 minutes to touch dry. Full drying: 72 hours.
Thinning: For best results thin with distilled water.
Clean Up: Clean brushes with warm water.
Constituents
Acrylic copolymer, Titanium Dioxide, Calcium Carbonate.
