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.

Grout Sealer?

Grout sealer is a protective substance used to prevent moisture, stains, and contaminants from penetrating and damaging grout lines. It is essential for maintaining the appearance and longevity of tiled surfaces like bathroom walls, kitchen backsplashes, and floors. There are two types of grout sealers: penetration/impregnating sealers, which absorb into porous grout, and surface sealers, which create a protective layer on the surface. Grout sealers offer several benefits, including stain prevention, moisture resistance, easier cleaning, and extended lifespan. To apply grout sealer, clean the grout, choose the right sealer, ventilate the area, apply the sealer, wipe off excess sealer, and allow it to cure. Regular reapplying is recommended to maintain its effectiveness. Epoxy grouts may not require sealing, so check manufacturer recommendations.

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..........

Yes - but you are always best off removing a large portion of the old grout before re-grouting. After letting the new grout dry for 48 hours, consider using a grout sealer to make it last longer.


How long does sealer for ceramic tile need to dry before walking on it?
