A. You can seal the grout the day after you applied it or 100 years later. If it isn't dirty, seal all three sides of the shower with a tile sealer or masonry sealer. That will make the grout water-resistant, if not waterproof, and help prevent the growth of mold and dirt.
We recommend waiting for at least 48 hours after installing a grout before you apply a sealer. Older grout should be cleaned thoroughly before being left to dry. Make sure to protect grout from spills and stains during this time, otherwise you'll be sealing in the dirt instead of keeping it out!
Grout is porous and therefore absorbs liquids. Because of this, the reason you should not seal your tile grout is that the sealer's liquid chemicals combine with the grout to create a surface that is actually much more difficult to clean.
When grout is not sealed in time, grime and water can seep into it, causing cracks on your tiles and forcing them to break at a certain point. By sealing your grout, you get to prolong your tile surface's lifespan and minimize damage to a considerable extent.
Grout sealer is a necessary component of the tile installation process. It serves to prevent moisture from working its way into the grout and under the tiles.
Signs Your Grout Isn't Sealed or the Seal Is Deteriorating
If you notice your tile grout is changing color, specifically getting darker when it's wet, you can be pretty sure the seal is broken and needs to have some grout sealing reapplied by a professional.

Some people will try to put a sealer on the grout joints, but that doesn't waterproof it. It doesn't work. It only makes it more water resistant.
For high-traffic areas, like the main bathroom, you should consider sealing it every six months, while low-traffic areas like the guest bathroom can be resealed every two years. If you are using epoxy grout, it might not be necessary to reseal it as it is highly water-resistant.
Benefits of Putting New Grout Over Old Grout
Putting new grout over old grout is not as complicated as a complete re-grout as it does not require the removal of the old grout. It can also strengthen the surface to increase water resistance and make it less susceptible to impurities.
It's important to thoroughly clean the grout before you seal it so you don't lock the yuck in! Mix dish soap and hot water and apply to the grout with a toothbrush. Let it sit 10-15 minutes. Brush the grout with a toothbrush and use a sponge and clean water to remove all of the soap mixture.
Yes, really! Re-grouting your tiles is an affordable and quick way of bringing your kitchen or bathroom back to life. Our easy-to-follow guide will show you just how simple it is to re-grout your existing tiles and freshen up your space.
The grout in your shower should always be sealed; this will block any moisture that could easily enter the very porous material. A sealer will prevent water from becoming stuck behind the tile and grout, forming mold and mildew.
Yes, certainly. Grout isn't a waterproof material, and lets water through. A properly-built shower takes that into account by giving water a path to the drain beneath the tile. If you don't have a leak, however, you can choose to fix little cracks or openings as an aesthetic choice.
Grout sealer will not harm porcelain tiles if it gets on them while you are working. That said, it can dry clear and shiny, and this may be noticeable. It may be particularly visible if you have bright or overhead lights in the space where the tiled floor is located.
Moisture and direct water contact contribute to grout deterioration over time, and eventually, the tiles will crack. This is why you should consider regrouting shower tiles every six months.
Be sure to let your grout sealer dry thoroughly before testing a small area with a few drops of water. If the water beads up, you're all set! If not, you'll need to apply an additional coat of sealer to your grout. Most grout sealers take 1-3 coats for best results.
Grout doesn't last forever. You can expect a lifespan between eight and sixteen years. Its lifespan will vary depending on how you treat your shower. Odds are, you have no idea when your grout was installed.
The only type of grout that doesn't need sealer is epoxy, which is inherently pre-sealed. Grout sealers typically come in two forms-- spray-on sealers and applicator sealers. Applicator sealers are applied directly to the grout with a roller ball or a brush.
However, over time, water will slowly start to penetrate the sealed grout allowing mildews and molds to grow again.
If it gets darker or changes color, it is a clear indicator that the grout hasn't been sealed. However, if the color remains the same, the grout has been sealed properly. Another way to check if the grout has been sealed is to monitor the water beads.
It costs between $0.90 and $1.60 per square foot to seal grout based on the size of your tiles, where you live, and the condition of your grout. Grout sealing usually includes cleaning, but always ask your contractor before you agree to a price.
