Most clear sealers will be ready for surface traffic within two hours after final coat under normal conditions (humidity, tile & grout porosity, and air temperature etc). The sealer should achieve full cure in 24 hours depending on the sealer giving your tile and or grout resistance against water, oil, and acid based contaminants causing stains and discoloration.
Penetrating sealers are designed to create stain resistance. The objective is to create reaction time, where a stain can be held at the surface level where it can be easily cleaned within a reasonable period of time before it is able to be absorbed into the porous surface. For 100% stain protection we recommend that you talk to us about Epoxy Coloured Grout.
Once we have completed the cleaning process, Porcelain Tile Specialist can seal the tile & grout using a professional clear penetrating sealer that will provide future resistance against staining and contamination.
To achieve maximum cleaning results requires a combination of the right tools and equipment, chemicals and professional cleaning products, heat (very hot water) and most of all knowledge of what needs to be used and how in any given situation.
