After Grouting: Once grouted, make sure that all grout residue is removed from the surface with a clean sponge and water. Allow grout to cure per manufacturers specification. If grout clean up is not performed effectively, an additional cleaning may be necessary to remove remaining grout residue or haze. For this procedure use Phosphoric Acid Cleaner , (GCFR) Grout & Concrete Film Remover (Hydrochloric Acid), Sulfamic Acid Crystals or Epoxy Grout Film Remover following the instructions carefully. Once the area has completely dried, proceed with the sealing of the grout for water and stain resistance. Apply Miracle Sealants 511 Impregnator Sealer to all grout with a paint brush.
Any excess sealer that gets on the surface should be wiped off with a clean towel before it dries. On larger jobs grout can be sealed by retreating the entire area including the tile or stone surface a second time. Be careful not to allow the sealer to puddle or dry on presealed surfaces.
