Is Sealing Your Grout Necessary?

You might be asking if sealing your tile surfaces is necessary after you put new tiles on your countertops, walls, showers, or floors. Installers usually wait for the grout to dry before proceeding. They use a grout sealer after that. So, what happens if a grout line isn’t sealed?

Grout is often constructed of cement, which makes it porous. This is why it is so good at absorbing liquids. As a result, grout sealing is required for your tiled surfaces. Grout sealing is also beneficial since it prevents mould and mildew from forming on your grout. You can use a grout sealer to boost the strength of your growth, making it more robust and reducing wear and strain. Tile and grout cleaning experts in Newcastle provided additional tips below.

Grout sealing extends the life of tile surfaces.

Grout that has not been sealed in a timely manner might allow dirt and water to seep in, producing fractures in your tiles and driving them to break at some point. By sealing your grout, you can significantly extend the life of your tile surface and reduce damage.

However, because not all grout is formed of cement, there are some exceptions when it comes to grout sealing. Certain grouts, such as epoxy grout, do not require sealing because they are not porous like their counterparts. As a result, epoxy grout is commonly used on non-porous surfaces such as glass to protect them against water and stain damage. Epoxy grout is noted for its flexibility, which makes it less likely to chip and split. However, before applying epoxy grout, you must first seal the unsealed tile.

On a similar note, certain tile surfaces, such as those composed of non-porcelain ceramic tiles, may not require sealing. Ceramic tiles, for example, are finished with a durable coating to avoid stains on the surface. Adding a sealing solution is rarely necessary for this situation. Porcelain tiles, on the other hand, will almost certainly require a specific sealer. A grout sealer, on the other hand, is required for natural stone surfaces such as granite, slate, travertine, and marble. Natural stone is porous, making it susceptible to stains and dampness.

If you’re not sure whether you need to seal your grout, do a simple test. Apply a few drops of water to the grout. It’s a telling sign that it has to be resealed if it absorbs the water.

Grout sealer is required for a variety of reasons

Grout is just a sand and cement mixture. As a result, if you don’t seal your grout, water, bacteria, and stains will seep in. A grout sealant protects your grout by making it water-resistant and resistant to bacteria. Grout sealing helps to maintain the look, texture, and consistency of your grout while also preventing mildew and mould. The appearance of your grout will improve, and it will last longer.

The only exception is if you’re using epoxy grout. A separate substance is used to make epoxy-based grout (which is more expensive). It’s a popular choice for glass tile installations (especially for kitchen backsplashes).

When do you apply grout sealant?

You should wait at least 48 to 72 hours for the grout to dry and cure after you’ve put in new tile. Make sure your grout is clean and dry, and that none of the lines is cracked or chipped. If they are, touch up the grout and wait for another 48 to 72 hours before starting to seal the grout.

Do you also seal the tiles?

In general, if your tile is glazed ceramic or porcelain, you should not seal it. Because unglazed tile/clay (e.g. unglazed terra cotta…not very popular these days) and natural stone are porous, you need to seal them.

Keep in mind that you should never use grout sealer on non-glazed tile or natural stone. If you do, it will be absorbed by the tile and will never come out (and it may be discoloured). If you’re not sure what kind of tile you have, contact the retailer where you purchased it.
