Made By Mineral Paint is formulated with a built-in topcoat and does not need sealing. To remove unwanted drips or brush strokes between coats, sand when the paint is touch dry. Avoid sanding the final coat of paint where possible, as this will disturb the built-in topcoat and will need resealing. For added durability and protection in high traffic areas, applying a sealant is recommended. Use any of our Waxes, Polyseal or Finishing Oils to both protect and achieve the desired decorative look for your piece.
