Which is better sanded or unsanded grout?
Sanded grout is more durable and stable for interior flooring. Unsanded grout can be prone to severe cracking when pressure is applied to it. Use unsanded grout for walls, countertops, and bathtub enclosures because it clings to fine surfaces and hairline grout lines better than sanded grout.

Unsanded grout is your best bet when you're working with soft, polished tile like limestone and marble. Always use unsanded grout when working with a soft, smooth, polished tile like limestone or marble, since abrasive sanded grout will likely scratch its surface.
Good to Know: Unsanded grout does not contain sand and is a less common choice in tile applications. Although it's not as porous as sanded grout and therefore less permeable to water, it's still recommended to finish with a sealer especially in wet or high-traffic areas.
Epoxy Grout: Epoxy grout is considered by many in the industry to be a superior choice for any kind of tile project. Epoxy grout is durable, doesn't need to be sealed, is stain and chemical resistant, and can withstand high traffic and moist areas.
Unsanded grout can be prone to severe cracking when it has pressure applied to it, making it unsuitable for most flooring applications. Sanded grout is the go-to choice for most interior flooring installations.
Epoxy grout is water resistant and made from resins and fillers that help it work like a sealing adhesive. Epoxy grout is a better choice for showers, kitchen, bathrooms, and other damp areas because it is stain resistant and requires no sealing, unlike cement-based grout.
Both sanded and unsanded grout will work well for bathroom and kitchen floors and shower pans. However, only unsanded grout is recommended for the following applications: Rectified tile. Shower walls.
While the coarseness of sanded grout may make it a bit more challenging to clean, the sand itself shouldn't scratch most types of ceramic or glass tiles. However, if you have tile with a high-gloss finish, you should spot-test a small amount of the dry grout on a loose tile prior to grouting and installing it.
Unsanded grout is the other type of cementitious grout. And, like sanded grout, unsanded grout typically takes up to a full 72 hours to cure. You'll also need to apply a penetrating sealer when using unsanded grout in a bathroom.
What happens if you don't seal sanded grout?
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.
Best Heavy-Duty Grout Sealer—STONETECH Heavy-Duty Grout Sealer. Suitable both for sanded and unsanded cement-based grout, the STONETECH Heavy-Duty grout sealer will protect grout from mildew and stains, without altering the color of the grout.

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.
What color grout is easiest to keep clean? The grout color that's easiest to keep clean is likely to be a neutral shade such as a gray, or a tone of beige. These are super-practical choices for both kitchen and bathroom tile, and will demand less maintenance to stay looking good as new.
Sanded grout is the most traditional type of grout that has been around for a long time. It is a cement base with added sand, which gives it a decently strong hold. Sanded grout is usually used for thick grout lines ⅛” inch or larger, up to 1 inch.
epoxy grout is a great choice when you are ready to re-grout a tile project. Because epoxy grout is so much stronger than other types of grout (particularly cement grout), you won't even need to remove all of your old grout. You can apply new grout right over the top of the old grout.
Non-sanded grout is best used for vertical tile such as in the bathroom and showers. This grout is better working material and sticks better to vertical surfaces than sanded grout.
Grout can crack when there's too much water mixed into the grout, which create tiny pinholes. When the grout dries, these pinholes make it easier for cracks to form in the grout. Too much water in grout can make the grout weaker. Grout can crack due to thinset (glue) that is applied over the mortar during installation.
Too Much Water or Additive
If the original solution is not mixed correctly, this can lead to cracked grout. As the grout dries, the water in the mixture will evaporate. Adding too much water or additive can lead to air pockets and make the grout weak. Thus, making it crack easily.
Generally speaking, white or light grout isn't as forgiving of discolorations and staining, and ends up requiring extra upkeep to make it look good. Darker grouts, on the other hand, can hide typical stains better, but they're more likely to fade or stain from cleaners.
What types of grout are waterproof?
The only Grout that is waterproof is Epoxy Grouts these do not allow water to pass through them, they are impervious to water.
Penetrating sealers are the best choices for use in especially damp areas, such as bathrooms—particularly showers. Membrane-forming sealers create a coating on the surface of the grout that resists water permeation. (These sealers work well in the kitchen but should not be used in the bathroom.
There's a reason why epoxy grout is considered the best grout for showers. It is incredibly resilient, with a better bond strength compared to cement grout. As anyone with an epoxy grout bathroom will tell you, this type of grout is less prone to stains than traditional grout which also absorbs water easily.
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.
Sanded grout is more durable, and is typically used for floors where the tiles and grout lines are larger. Unsanded grout is often used for high gloss or glass tiles to prevent scratching the surface. Sanded grout is for wider spaces between tiles - anything over â…› of an inch.
- Mix 1 tablespoon liquid dish soap, ½ cup baking soda and ¼ cup hydrogen peroxide together in a squeeze bottle.
- Apply cleaning solution to grout lines.
- Allow to stand about five to 10 minutes.
- Scrub with a scrub brush.
- Rinse thoroughly.
Floor grout, in general, usually dries completely after 24 hours, although humidity and other factors can extend this drying time to 48+ hours. Grout haze can sometimes be simply buffed out with a dry towel or cheesecloth, if done immediately within the first 48 hours.
Sponging the grout too soon will pull it out of the joints, so let it set for about 15 minutes. After that, use a damp sponge to clean the face of the tiles in a light, circular motion. Next, clean the sponge and go over the tile again, wiping at a slight diagonal to the joint.
Maximum of 1 year from date of manufacture in unopened package. Product is good for 6 months after opening. (Re-seal and store in cool, dry location, use within shelf life.
A majority of builders do not include sealing your freshly installed Grout. This is for a variety of reasons that boil down to not wanting to be responsible or have any warranty calls regarding spills and stains. For the builder it makes total sense, for you the New Construction Home Owner it totally stinks.
Does all grout need a sealer?
Porous grouts attract water, dirt, oils, etc. While the tile industry does not require sealing, it is always recommended, especially in wet or high-traffic areas. Penetrating sealers are the most commonly used and offer high water, chemical and stain resistance.
Tile or stone with high absorption, surfaces that are porous or rough, textured surfaces and some types of porcelain tile may require sealing prior to grouting to prevent possible staining. Use Aqua Mix® Grout Release or TileLab® SurfaceGard® Sealer to prevent staining when required.

SINGLE COMPONENT GROUT
It shares many of the benefits of epoxy grout: it has excellent color consistency, doesn't need to be sealed, resistant to breakage and chemicals, resists mold and mildew, is stain resistant, and doesn't effloresce.
The easiest way to clean grout without scrubbing involves hydrogen peroxide and baking soda. Mix the two into a paste with some dish soap and apply to the grout lines. Alternatively, you can use a cleaning solution of water, vinegar, lemon juice, and baking soda.
Epoxy grout is made from two different resins mixed with a filler, making it very waterproof and bettered suited to harsher cleaning products. Epoxy thinsets offer greater bond strength and chemical resistance than cementitious grouts.
If you try adding new grout over your old grout, the new mixture will not properly adhere to the existing grout or tile edges, leaving your shower open to water damage.
At this point you may wonder if a complete re-grout is necessary or if it would be possible to simply put new grout over old grout. The answer is, yes, it is possible to put new grout over old grout.
In most cases it's best to grout first to create a solid foundation for the tile. Once the grout has set and hardened, the caulk can be used to provide a waterproof seal.
Because sand has a significant grit, there is a higher chance of it scratching delicate tiles such as marble or limestone. Sanded grout is best used with floor tiles, ceramic tiles, natural stone tiles, and porcelain tiles.
Is sanded or unsanded grout better for stone?
For example, unsanded grout is recommended for highly polished, easily scratched tiles such as marble or granite because the aggregate in sanded grouts may damage these types of tiles. Over time, the exposed sand at the surface of the grout may loosen from the surface, and the sand may actually scratch the stone.
Epoxy grout – the best grout for natural stone tiles. Epoxy grout is strong, form impermeable seams and is resistant to staining. It could well be said that this is the best grout for natural stone.
Sanded & Unsanded Grout
Sanded grout is classified as a cement grout that has 1/8” or larger grit to it. Unsanded grout is a cement grout with less than 1/8” grit. Generally, unsanded grout is used for tile applications with narrower grout joints, from 1/16” to 1/8”.
If your grout is a few years old, it's normal that in time, it will crack. This results from a few key causes: Exposure To The Elements. A common problem for wet areas in the home, like the bathroom or shower, grout tends to crack here as a build-up of water slowly eats away at the material.
Sanded Grout: Generally 1/8” to 5/8” inch can be used. Unsanded Grout: Generally 1/16” to 1/8” inch can be used. All-In-One: Generally 1/16” to 3/4” inch can be used.
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.
Sanded grout is recommended for any install using ceramic, porcelain, granites, flamed or brushed marble, terrazzo, rock pebbles or meshed pebbles with a 1/8" or up grout joint.
Epoxy grout.
It is also easier to clean and more likely to return to its original color than cement grouts, which is a big plus if you're tiling with white or another light grout color. Epoxy grout is also less prone to cracking. On the downside, however, it's more expensive than cement grout and takes longer to apply.
The writers from Rogue Engineer state that applying grout on an unsealed natural stone will result in the stone absorbing some of that grout, bonding with it quickly, and resulting in discoloration and dried grout, which is almost impossible to remove without damaging the stone.
Epoxy grout is stain resistant and water resistant because it isn't porous like cement grout. This means epoxy grout lasts longer than cement grout. It also makes epoxy grout the best choice for both indoor and outdoor settings, particularly in spaces where you can expect a lot of moisture.
Why do you need to seal stone before grout?
All natural stone tiles, whether polished, honed, or tumbled, are porous and require sealing before grouting. This essential step fills the pores with a protective sealer, preventing grout particles from causing a hazy surface appearance on your tiles.
