Grout is a porous material that absorbs soil and spills. Having sealant applied will help create a protective barrier, giving you more time to clean up dirt and liquid spills before they soak into the grout. After cleaning we recommend that you have the grout sealed. This helps the grout stay cleaner, longer and maintenance is simple because the soil doesn’t penetrate deep into the pores, instead of remaining on the surface for you to clean off. Sealing grout with these products will not change the appearance or colour of the Tile and grout, and they are designed to prevent moisture from absorbing into the grout where it would otherwise leave a stain.
