That’s why people can use it inside or outside of the houses. Different kinds of grout surfaces, including glass, ceramic, tiles, bricks, concrete, will look good with this sealing agent.

When it comes to longevity, silicone sealants rule over other similar products. We expected the same from this grout sealer, and it didn’t let us down. Nothing can beat its work for fixing bathroom sinks, cracked lines, and gaps between tiles. As the manufacturer’s claim, the coating doesn’t require further re-application for up to five long years.
We are happy with the way it repels water penetration. The finished layer will never trap moisture inside. Thus, your floor will not get any scopes to build up mildews, germs, and bacteria. Also, cleaning the sealed area is easier than an unsealed part.

Homax Tile Guard Silicone Grout Sealer, 4.3 oz
It is another masterpiece from the Homax brand. The key differences from the previous one are the quantity and applicator. Other features are almost similar. It is mainly famous for high abrasion, UV radiation, and temperature tolerance. Customers do not have to re-apply within a few years. But re-whitening is mandatory to sustain its charm.
This penetrating sealer does not offer color and gloss enhancements. It operates by raising surface tension. Water can enter inside the coating. It converts to some droplets rather than being absorbed. It also evaporates easily. Mildew build-ups are impossible on such floors.
Unlike the other water-based sealants, it is fragrance-less, non-toxic, and safe to use. Almost no chemical substances, which are harmful to the human body, are present there. It acts as an invisible protective layer after drying. Thermal exposure, salt water, regular uses, impacts do not result in damages or decay.
Clean the area well before and after pouring sealants. It has a liquidy texture, but it will harden later. You may wait until four to six hours. The floor won’t get sticky or slippery. The only drawback is, it does not work well on the shower grouts.

StoneTech Heavy Duty Grout Sealer, 1-Quart (.946L)
The sealant ensures heavy-duty protection against all damages and stains. It does not affect the grout color. So, applying on a light grout line does not darken the appearance. Only a natural look is visible. It is appropriate for the majority of kitchen tasks but not for washrooms.
Be careful during your work. Bring out the old grout segments and brush away the dirt. Next, pour the sealing solution at a slow pace. It should not dry on your tiles. Get rid of the residues, debris, etc. Apply the next coating on the dried first layer.
After sealing, you have to focus on proper maintenance. Well-maintained works do not fade away from two to four years. However, if you use harsh detergents, steaming machines, or hot vinegar cleanser, their lifespan will decrease. The sealing layer may crack, and another application should be done after one year.
It makes cleaning more effortless. When something drops, the grout lines do not absorb the oil and color. It is the reason behind the ease of cleaning. Get mild detergent, mix with water, dip a cloth into it and scrub the stains away. As simple as that!
Features At A Glance
- Resistant to most stains
- No changes in the original grout color
- Last for years to come
- Appropriate for a variety of floors

Aqua Mix Grout Sealer Dual Protection
Our last champion belongs to the Aqua Mix brand. It implements water-based strategies. So, it is not injurious to your health. The smell is a little bit weird, though. It is not too strong to induce a headache. Even after continuing your work for days, you will be completely fine.
If you don’t like silicone sealants, try this unit. Its performance is way better. When anyone coats the grouts, it forms a shield after drying. This shield repels water, oil, grease, debris, etc. It demotes bacteria and mold growth. Such a layer lasts a maximum of five years.
Another advantage of the sealer is its functionalities regardless of the grout varieties. There is no restriction of working with cement-based sanded or unsanded grout lines. It will beautify your natural stone, porcelain, glass, brick, or other floors by giving a clean look. But the grout coloration will be the same. Take care of the grout joints regularly after sealing.
We found it challenging to use the sealant. Its application becomes messy unless you use an applicator tip. We hope the authorities will add a good-quality applicator along with the sealing solution. Maintain half an hour gap between consecutive applications.
Features At A Glance
- Water-based sealer
- Anti-contaminant service
- Robust formula
- Better than silicone sealers
- Routine cleaning endurance
- Perfect for both cementitious sanded and unsanded grout lines
What Should I Look for When Buying a Grout Sealer?
As a buyer, you can find out the best floor grout sealant by these considerations:
Know the surface type
Versatile units always act well on every kind of floor, including stone, tiles, mosaic, ceramic, marble, porcelain, and so on. There are also tons of sealers that are suitable for only one or more particular surfaces.
Some are specially designed for washroom and kitchen applications because these floors get in touch with water the most. Cement-based grout lines become susceptible to damage quickly. A sealer is a must for them.
It plugs their porous areas and provides a clean coating. On the other hand, proxy-based grouts hardly require sealers. Their tightly bonded elements develop a smooth, heavy-duty, water-resistant, stain-proof layer anyway. But you can buy sealers to boost the appearance.
Choose from penetrating and non-penetrating options
We can divide all sealers into two classes based on their liquid penetration facilities- non-penetrating and penetrating. The former gives an ordinary performance. Their application procedures are straightforward and take less time.
Do not expect them to last more than a year. As the name suggests, they don’t allow any water to gather inside the grouts. A membrane forms after their application that seals the grouts completely and locks moisture too. These properties make them the best grout sealer for kitchen backsplash but non-ideal for restrooms.
Places, which stay damp most of the time (showers, spa rooms, bathtubs, washroom), need a penetrating one instead. It lets the trapped water molecules evaporate without any chance of growing mildew. The natural-looking finishing will remain safe from oil damages as well, at least for three years.
Understand the levels of toxicity
Prioritize safe varieties as much as you can, especially if you have children. Always check the ingredient list before shopping. Try to avoid brands, which launch products with formaldehyde, VOCs, and many more. Solvent-based grout sealers are the most harmful sealer of all.
Their construction involves the use of heavy chemicals or toxic materials. Buyers notice serious health issues after inhaling or putting them into the mouth accidentally. Wear goggles, masks, gloves prior to their application. Store them away from heat and fire sources.
Water-based models are comparatively safer. Many studies prove that they have fewer VOCs and other harsh elements. Take the same precautions you would take for the solvent-based sealers.
Get the right applicator tip
Applying a sealer can be a messy task. In most cases, you have to repeat the whole job twice. You may end up dropping it all over your tiles. Then, you have to spend more time cleaning than applying it.
Only the right application method can save you. Several sealants come with the perfect applicator for your surface. It can be a roller brush, sponge, tube, or spray nozzle. Brushes with small tips deliver the most accurate output.
The secret is, they release a minimal amount of sealing solutions. Another convenient choice for filling small spaces is tube-shaped applicators. If your picked model does not contain an applicator, purchase it separately.
Make your budget
Most grout sealers are not too expensive to buy. They typically cost from $.50 to $1.50 or slightly more per square foot. But the price raises for additional, exclusive features. For example, if the deal covers accessories, it may cost more than the regular models.
The scenario can be the opposite too. You can find many high-quality sealers below the average cost and poor-quality sealers at a high rate.
We strongly recommend fixing your budget and buying the best one from your capability range. Manage at least $15 per quart. Order easy-to-use items because taking professional help wastes more bucks.
