How do you seal my tile and grout?

We use an impregnating sealant. These sealants are water or solvent based solutions that penetrate below the surface and become repellents. They are generally hydrophobic (water repelling), but are also oleophobic (oil repelling). Impregnators keep contaminants out, but do not stop the interior moisture from escaping. By using the proper cleaning products, your sealant will be able to repel soil for a long time.
