Grout sealing and colour sealing
Grout sealing after tile has been newly installed or freshly cleaned is a very important step in keeping the grout protected from stains and soiling. Grout is very porous allowing dirt and grime to "seep" into the grout making it very difficult to clean if not protected. Not to mention unsightly.
Colour sealing is done when certain stains have been set because the grout was not sealed and/or the material was left on it for too long a period. In this case, colour sealing will help to match grout colour. Another good reason to colour seal is if you decide that you would prefer to have a different coloured grout. Instead of removing and replacing all the grout, the grout is coloured to the colour that you choose.
Colour Sealing is different
Grout Perfect® Colour Seal has a modified-urethane base, the modification is in the hardener, specifically a concrete hardener. Since sanded grout is merely concrete with a (powder) colour added, this works perfectly to bond and fill the grouts pores and strengthen the surface. The roughness that can be felt after our process is completed are the small sand particles in the grout (concrete) protruding up from the surface of the grout; however all the concave pores are filled with our sealer to make a waterproof and air tight covering. This waterproof and airtight seal coupled with the mildicide and fungicide in the sealer when correctly applied renders the grout line mould and mildew resistant indefinitely when properly maintained
