How to Stop Grout Leakages. To maintain the integrity of grout, you will have to apply a grout sealer. It is necessary to apply the sealer after 1 to 2 years so that the grout remains intact and waterproof.
Penetrating sealers are the most commonly used and offer high water, chemical and stain resistance. They provide protection without changing the appearance of the grout joint.
The most likely place for the water to be seeping in behind the tile is where the walls meet the floor. This transition should be caulked with silicone caulking. You can use either clear or a color matched caulk if one is available.
The Drawback of Using Grout Sealer
Moisture can still pass through most sealers, meaning grout isn't entirely waterproof even when sealed. Over time, grout in areas like bathrooms will naturally stain or show signs of aging, regardless of sealing.
Whoever installed your floors most likely did not seal the grout because it needs time to harden and cure completely.

With sufficient maintenance and care, your grout color sealer can last up to ten years or even more. Apart from maintenance, your grout's lifespan also depends on the type of product. To keep it clean and crisp, avoid using solvent-based paint strippers to the tile as they can remove the grout paint.
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. You may also notice dirt and grime gathering between your tiles that doesn't wipe off when you apply a grout cleaner.
Using Too Much Sealant
You might be tempted to use more grout sealer to get the job done quickly, but an excess amount can easily spill over onto the tiles. As a result, unnecessary time will have to be spent scrubbing the excess sealant off.
Epoxy grout doesn't need to be sealed at all.
Either you don't have a vapor retarder or it was installed in correctly. You could remove the grout and install an impervious epoxy grout or an ASTM C920 sealant in the grout joints to make it water tight, but the water migration can still cause problems to the marble.
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.

To seal to perfection, we recommend using Universeal Grout and Tile Protector. This product is a solvent based sealer designed to deeply penetrate your grout. It is effective in preventing stains from oil and water-based liquids and it will not discolour your tiles.
This means that while water cannot enter the substrate, any water vapour can still freely travel through the pores and breathe out. The best way to think about an impregnator vs a sealer is that an impregnator waterproofs the substrate itself, while a sealer creates a waterproof film on the substrate.
Unsightly Grout Stains and Discoloration:
One of the most noticeable effects of neglected grout sealing is the gradual accumulation of stains and discoloration. Grout is porous by nature, which means it readily absorbs liquids, dirt, and debris.
Allow to Dry: Let the sealer dry as per the manufacturer's instructions, usually ranging from a few hours to a full day. 5. Reapply if Necessary: Some sealers require a second coat. If so, allow the first coat to dry completely before applying a second layer.
Take a close look at your grout lines before and after wetting them. Be on the lookout for missing grout or obvious holes. These are the likely culprits when you have a leak in a tiled area. All you need to do is apply new grout to any portions that seem vulnerable.
If you are wondering how long you should wait between grout sealing on your high-traffic floors or frequently-used showers, the answer is at least once per year. However, The Grout Medic recommends sealing those areas every six months.
Sealers may be suspended, carried in water, or a solvent. Water-based or water-carried sealers are less expensive and have much fewer health or safety concerns. Water-based sealers are generally preferred in most situations. Solvent-based sealers must be used in well-ventilated areas, sometimes with a respirator.
We recommend resealing every two years to protect your driveway and help keep it in top condition. You may need to reseal more often if your driveway is exposed to heavy traffic, excess dirt or friction (eg from tyres).
Let the first coat dry for an hour before applying a second coat. Depending on the grout sealer you choose, allow 24 to 48 hours for the second coat of sealer to cure. After the second coat completely dries, test the surface with a few drops of water. If the liquid beads up into droplets, you do not need another coat.
