Tile & Grout Questions... Why should I have my tile and grout cleaned? Just like carpet, dirt builds up over time dulling your tile's appearance and discolouring your grout. A thorough, professional tile and grout clean is the only way to remove the deep-down dirt. Why should I have my grout lines sealed? Grout is a porous material that absorbs soil and spills, just like carpet. Having a sealant applied will help create a protective barrier, giving you more time to clean up dry and liquid dirt before it soaks into the grout. The type of sealant you choose will determine the degree of stain resistance. How long do I have to stay off the floor after sealant has been applied? We recommend that you wait 30 minutes before walking on the floor to allow the sealant to dry. It will take 24 hours for the sealant to cure completely, so we suggest that you avoid any liquid coming in contact with the sealant during that time. Do I have to use a special floor cleaner if I have the sealant applied? To preserve the life of the sealant, we recommend that you use a neutral cleaner on your floor. Rinsing after mopping will also help keep your floors looking their best. You will want to avoid bleach and other harsh chemical cleaners as these can wear away at the sealant and cause it to break down prematurely.
