Apply sealer as soon as the grout has lost the "Heat of Hydration"; usually in a matter of hours. Choose a sealer carefully! Read the cautionary statements on the product you are considering! If it cautions "Do Not Allow Product To Come In Contact With Glass or Metal Surfaces" Don't even consider it! More than likely a Sodium Silicate based product that migrates out of the grout very soon, and it will etch glass and any metals it comes in contact with! If it allows for a Re-Coat at some future date? Ask yourself- OK, what happened to the first application I put on?

You put sealer on EARLY to waterproof the grout and stop the rapid evaporation of mix water from the material. This evaporation causes shrinkage cracks in the grout. Even Microscopic cracks in a grout will increase in size with traffic and result in a delamination of the grout. I use a product called that is manufactured exclusively for, and sold by my company. Waterproofing grouts immediately will retard evaporation of mix water and give a superior bond to the tile itself [on the side of the joint] and to the substrate [host concrete] below. You will know when you have achieved proper saturation levels of the product when it is no longer being absorbed into the grout. Come back the next day and pour water on the area you have waterproofed; it will pond and remain on the surface until it evaporates.

In kitchens or on a rough sanded grout I make another application the next day. If the second coat is not able to penetrate the grout I know its waterproofed and mop up the excess product. This prevents the product from drying on a surface to form a film. The product works by forming a solid inside when it reacts with the alkali and does not leave a film. When friends come to my house and comment on my kitchens "New Tile" I pour Grape Juice or ketchup onto a joint, proceed to tell them it's 6 years old, it's waterproofed grout, with a 15 year warranty for waterproofing and after 10 or so minutes-- I wipe the Stain up!! If you waterproof the host concrete beneath your tile install, you will also avoid a delamination of the thin set mortar that holds the tile in place. That hollow sound of a tile when you walk on it, is a dead give away that the tile is no longer bonded to your floor. Do it right the first time and ASAP.

Is it good to seal tile and grout?

Yes.... But if the tile is glazed and/or the grout is epoxy (unlikely unless in a commercial building) these do NOT need to be sealed (neither will absorb water so they won't accept the sealer). The rule of thumb is to put a few drops of water on the tile and the grout, if it soaks in within 30 seconds it needs to be sealed. Never use a topical sealer. Always use a waterbased PENETRATING sealer. You will need to reapply bi-yearly or yearly in most situations, more if the tile is exposed to water. Hope this helps..........

How often should you seal your shower grout?

You don't ever have to re-apply grout, unless there are visible cracks in the grout or chunks of grout that have actually fallen out. You can re-grout these areas. Use a hand held grout saw (preferred)or a flat head screw driver to score the area of grout that is cracked or missing, then you can re-grout these areas. If it is a bathroom tile, it is most likely a NON-SANDED grout, and you mix it up to a stiff, creamy consistancy. Spread it over the areas, pressing it into the cracks with a grout float or your finger. Try to pass the sponge at an angle over the vertical or horizontal lines of grout, this prevents the grout from coming back off. Wait for the grout to become dry enough that you can gently pass a grouting sponge over the grout without wiping it completely off. After the new grout has set and is pretty much dry, you buff the area with a dry cloth. If the grout is smooth and pretty much flush with the files, grouting is a waste of time. It would have to be such a thin layer that it will eventually flake off. Some people apply a SEALER every year or so, and this prevents water from penetrating the grout and getting behind the tiles, possibly damaging the walls. The sealer is applied with a bruch or an applicator bottle, and you just squeeze it onto the lines of grout, wait for it to soak in, and wipe off excess on the ceramic tiles, as it won't oak into the tile itself. Oh gosh...This is'nt what you asked. .__. Sorry,my bad.


How do you clean grout?

Video: How do you clean grout?How to clean grout:1. Mix a quarter cup of bleach to about a half gallon of water. Depending on the type of cleaning you have to do, Oxyclean or any of several grout cleaning products at Lowe's will do the job. Tilex or Lysol shower cleaner will do the job, too, but with a harsher chemical that may bleach or stain surrounding surfaces.2.

How do you clean ceramic floor tile grout?

You should only use a mild soap and water solution for cleaning grout on floor tile. If it was properly sealed this should work fine. If it was not sealed and the dirt has worked its way down into the grout, you can either use a grout renew which is sort of like a paint for grout, or you will have to have the grout replaced.
