After approx. 4 - 6 hours (according to the temperature) a second coat may be applied, if desired with diluted Primer. Between the two coatings, uneven fibres and knots can be flattened with a fine abrasive paper. Coated fabrics can be rolled.On absorbent supports like paper, cardboard, fibreboard etc., Lascaux Primer or Gesso is applied diluted with 10 - 15% of water, as required.On wood or concrete, a preliminary impregnation with Lascaux Hydro Sealer, diluted 1:4 with water, is recommended. For the following coat of Lascaux Primer or Gesso, dilute with 25% of water.Lascaux Gesso should not be used below the temperature of +8°C (+46°F).Lascaux Primer or Gesso can be tinted with acrylic colours.
