  • Lime Slag™ can be tinted with FauxCrème Color™. Because the high pH level in lime-based products can adversely affect certain colorants, do not use FauxColor™ with Lime Slag™.
  • Lime Slag™ can be dry sanded using fine sandpaper, 800 – 1200 is best for burnishing.
  • The normal ratio to use when adding Lime Slag™ to any product is 25% Lime Slag™ to 75% plaster or textured product.
  • When using Lime Slag™ as a burnishing or staining agent, thin with water, apply and then burnish when dry.
  • Ensure that the work surface is clean, dry and well sealed. For best results seal the surface with 2 coats of SetCoat® Clear or SetCoat®.
  • Mix approximately 32 oz. of Lime Slag™ into 1 gallon of Venetian Gem® plaster (about 25%).
  • Apply 1 to 2 thin, smooth layers. Allow each layer to dry thoroughly.
  • Once the work surface is dry, burnish the surface with a good quality stainless steel trowel held at a 30º angle. For the final burnish hold the trowel flat against the surface and move in a circular motion to finish compressing and shining the finish.
