Our Grout, Tile & Stone Sealer – Quick Drying Aerosol will not affect paint, because it is such a fine spray and quick drying. If using liquid Grout, Tile & Stone Sealer – Quick Drying or Grout, Tile & Stone Sealer – Slow Drying, it is best to cover up the painted areas prior to sealing. Clean off any overspray immediately with a damp sponge or cloth.
