Best Budget

Black Diamond Stoneworks Ultimate Grout Sealer

$24 At Amazon View On Bdstoneworks.com

While an inexpensive option is a good choice for larger projects or for tighter budgets, you still need to be sure the sealer gets the job done. The Black Diamond UGS PT Ultimate is the best choice for this since it’s meant to resist even tough stains from coffee, wine, and oil, yet it won't break your budget.

Grout can sustain significant damage from water and oil over time; this sealant is made to prevent that. In places where moisture is common, such as the kitchen or bathroom, this type of protection can reduce the amount of maintenance your grout and tiles will need after extensive use. Like most grout sealers, this one is available in several container sizes, including spray bottles.

_{Application Method: Spray, rag or sponge | Water/Solvent Base: Water | For Multiple Types of Surfaces: No}

Best for Bathrooms

Aqua-X Grout Sealer

$26 At Amazon $26 At Walmart View On Blackdiamondcoatings.com

Grout that's regularly exposed to moisture can quickly degrade, discolor, mildew, or even crumble. That's why a coating of Aqua-X Grout Sealer is so important. Just spray or brush this quick-drying sealer onto the grout, and wipe away any overspray from the tile. Once it dries, your grout is protected from moisture for up to five years. Although the product goes on white, it dries clear and won't change the color of your grout.

This is a water-based sealer with low VOCs, so you won't have to deal with awful fumes or odor. While highly effective at protecting grout that's routinely exposed to moisture, it's also a great choice for sealing grout elsewhere in your home, including the kitchen or even the backyard. It's available in pint or quart bottles.

_{Application Method: Rag, brush, or spray | Water/Solvent Base: Water | For Multiple Types of Surfaces: No}

Best for Floors

Clean EEZ Stone & Grout Sealer

$38 At Amazon

Keep your tile or natural stone floors looking their best with a grout sealer that locks out stains and discoloration from moisture and oils. Clean EEZ Stone & Grout Sealer is a water-based product that penetrates deeply into grout, ceramic tile, and natural stone for long-lasting, effective protection.

For optimal results, apply the sealant with the brand's grout brush, which is not included. Let it sit for at least five minutes to penetrate into the grout, and then wipe away excess. Apply a second coat and let it dry for 24 hours for full protection against moisture and other potentially staining substances. While an exceptional sealer for grout on floors, you can, of course, also use it to seal grout on countertops, backsplashes, and walls. It won't change the color or look of your tile or grout, and doesn't feel slippery underfoot. It's also safe for use around children and pets, and it doesn't have a strong odor during application.

Best Long-Lasting

Miracle Sealants 511 Impregnator Sealer

$31 At Amazon $33 At Home Depot $50 At Walmart

The challenge with grout sealers is depth. Since sand is porous, deeper holes need to be addressed, depending on the thickness of the grout. But most sealers use a water-based solution that doesn't penetrate much below the surface. This leaves the deepest portion of the grout unprotected. To reach further in, an impregnator like the Miracle Sealants 32-ounce bottle is necessary.

This sealer uses a solvent-based formula that penetrates deeper into the grout layer, unlike a water-based formula. The deeper penetration means extra, longer-lasting protection for the grout and surrounding tiles. The sealer dries into a slip-resistant finish, so it is safe to walk on treated tile floors without worry. The extra protection will also keep stains from forming, preserving the look of the tile surface. Formulated for both interior and exterior use, this sealer can also protect outdoor tiled surfaces on patios or around swimming pools.

Best Tube

Miracle Sealants Grout Sealer

$29 At Amazon $10 At Home Depot $14 At Walmart

Tube grout sealers allow for precise control over the sealant as you work without the need for a brush or rag. But since tubes usually don't contain a whole lot of product, they are best used for small projects or for touching up damaged spots. If you have grout, it's smart to keep a tube of sealant, like the Miracle Sealants Grout Sealer, on hand for spot repairs when needed. This helps to keep the grout intact over time.

The brush-topped tube contains 6 ounces of sealant, which should last a long time for the occasional touch-up or repair. Once fully dried, the sealer will resist mildew and stain buildup, making cleanup in bathrooms and kitchens easier and safer. The sealant also provides stain protection on tiles. It's a quick and easy way to tackle grout maintenance.

Best for Kitchen Counters

Black Diamond Stoneworks Granite Sealer

$23 At Amazon $26 At Walmart View On Bdstoneworks.com

Sealant formulas vary, depending on the brand and manufacturer. Some formulas are specifically for grout and nothing else. But if you want to seal grout on a large stone surface, such as a granite countertop or marble floor, a multipurpose sealant like the Black Diamond Granite Sealer may be a good alternative. It's quick and easy to apply and dries within just a few hours.

The spray-on sealer is water-based and non-corrosive, making it safe for granite, concrete, and most stone surfaces in addition to grout. The effective formula repels even tough stains from wine, oil, ink, and coffee, making it a great choice for kitchen counters and other dining surfaces. It's available in pint and quart spray bottles, as well as gallon jugs.

Best for New Grout

Advanced Sealers & Cleaners Ultimate Fast Grout Seal

$16 At Amazon $22 At Home Depot $17 At Walmart

Generally, grout has to be fully cured before you can apply sealer. That usually means waiting at least 48 hours, more often 72 hours, before applying the grout sealer and finishing your project. But with Advanced Sealers & Cleaners Ultimate Fast Grout Seal, there's no need to wait. You can spray this effective grout sealer right onto newly installed, damp grout without any change in grout color. The sealer dries very quickly, leaving the grout protected against water and oil stains. It also helps protect against grout color fading as the grout dries.

Of course, you can also use this easy-to-apply, fast-drying grout sealer spray on existing grout. It won't change the appearance or leave haze on the surrounding tile, whether that's natural stone, ceramic or porcelain tile, or masonry. This product is simple and straightforward to use. Because there is minimal overspray while spraying this product, you can target specific areas for application.

Best Against Oil Stains

StoneTech Heavy Duty Grout Sealer

$57 At Amazon $22 At laticrete.com

Whether it's spills of cooking oil in the kitchen, suntan oil around the swimming pool, or skincare products in the bathroom, oils can quickly create discoloration or stains on grout that are very hard to remove. StoneTech Heavy Duty Grout Sealer is a multipurpose sealant formula designed for both sanded and unsanded grout used with natural stone, porcelain, and ceramic tile. It’s formulated to provide the utmost protection against both water-based and oil-based stains, maintaining the good looks of your countertops, floors, or shower surrounds, and warding off ugly black spots, mildew growth, and other imperfections for months at a time.

For the most effective protection, apply this sealer with a paint brush or paint pad rather than a rag or sponge. You'll get a thicker layer of sealer that way. While it can be messy, this method of application helps to apply a thicker coat of sealer, which provides optimal protection against stains. Do not apply a second coat until the first one has dried entirely. To get the best protection, apply a third layer to areas that get a lot of moisture or are exposed to oils.
