The Best Grout Sealer of 2020 – Essential Buying Guide

Being a self-proclaimed DIYer, I have found over the years that the quality of the product does matter in the final result of your project. That is why I have decided to make this article about the 5 best grout sealers that I have found.

A lot of individuals may not realize that these types of products even exist; while I would be lost without them. Some of these I have found value in adding to my weekly routine of deep cleaning my tile floors, and have found that they do help to keep upkeep that much easier. While the old saying is accurate about every job having the correct corresponding tool, I have found that goes further and also applies to sealants for grout in tile floors.

The products listed in this article suit a specific purpose, although there are a couple that have multiple uses. I have noticed that some people over the years do not even know why sealing your grout is an important step in installation and upkeep of tile floors. That is because grout is essentially a mixture of sand and cement and it can absorb water; which can then lead to the growth of limescale, mold, and mildew. Sealing the grout in a tile floor will also ensure longevity.

After installing tile, it is recommended to wait at least 48 to 72 hours before sealing. During this time it is also highly recommended that foot traffic on the newly installed tile is kept to a minimum. The following grout sealers are all very easy to apply, and will ensure that you get the most out of your tile floors.

Clean-X Eliminate Grout Cleaner & Sealer

clean x grout cleaner and sealer

This is a great budget-friendly product for use when you are needing to clean and seal the grout on your floors. It comes in a 3-pack, which means it will go far from one single purchase. It’s a great way to not only clean your floors, and remove all of the stuck-on particles in the grout, but to also seal the grout lines to prevent further damage and debris from sticking.

This heavy-duty cleaner will keep your floors looking fresh and new, and at the same time and will help to prevent mold, mildew, and dust from building up and damaging the integrity of your tile floors. This cleaner and sealer will also help to make your life easier by lessening the amount of work that you will manually need to put in to keep your floors looking new, and staying durable. There is no need to use excess amounts of elbow grease that comes with scrubbing; you should be able to spray, walk away, and come back to wipe it down.

This is a great product both for cleaning and maintenance of your floors; you can’t use too much of it, and it can be added to your daily or weekly cleaning routine. Even if you don’t notice any dust, dirt, or particles that are in your grout, you can still spray and rest easy knowing that it will protect your floors from further mess.

PROS
  • Mess-free, won’t leave your floors with a sticky or slick residue after use.
  • Easy to use, simply spray, let sit for a few minutes, and then use a rag to wipe down and remove excess.
  • No need to scrub grout or tile, the non-harsh chemicals will take care of most of the work for you.
  • It comes in a 3-pack, so you can rest assured that you will always have the product on hand when you need to use it.
  • Can be used as needed; to clean and protect your floors, or to simply keep dust, mold, and mildew from growing and damaging the integrity of your grout.
CONS
  • Not as strong as other products for those tough jobs that require more harsh chemicals to kill mold and mildew.
  • The fragrance could be improved; if you don’t like the smell it can seem overwhelming.

Final Verdict

This is a great product that delivers on exactly what it is designed to do: clean and protect your floors from mold, mildew, limescale, and minerals. I like that you can use it either to clean and remove particles from your grout such as soap scum and ground-in dirt or as a protectant to keep your floors safe from anything growing.

A great cleaning product that I know I can trust to not only keep my grout clean from soap scum and mildew, but also remove bacteria and do a good job of keeping my floors clean. A quality product that is well worth it. And the fact that you can buy it in bulk is just another plus in my mind.

Homax Silicone Grout Sealer

homax silicone grout sealer

One of the best grout sealers on the market that I have personally used, this sealer comes in a 4.3 oz bottle that is convenient, easy to apply, and will protect your grout from moisture and stains. This water-based formula is almost odor-free, which is a huge plus for me; I enjoy knowing that my house is clean without smelling it. If you have tile floors outside, this grout sealer will also work on those; regardless of weather conditions.

Provides a 5-year protection guarantee, but can be applied in-between to make sure that your grout is looking white and fresh. Due to the size of the bottle, this grout sealer will store easily and requires little effort on your part to brighten up your grout as well as seal it to prevent against mold, mildew, and limescale buildup. There is no scrubbing involved, making application easy and worry-free; it dries clear with no tackiness or slick feeling.

Should not be used if there is already a presence of mold, mildew, or limescale as I have found this will not kill these. To do so, you will need a grout and tile cleaner before using this product.

PROS
  • Easy to use and apply, comes in a convenient 4.3 oz bottle.
  • No need to mark the area after application, as the product dries very fast.
  • Seals your grout and brightens it up; making it look new and fresh after every application.
  • One application will last up to 5 years.
CONS
  • Is not recommended for use around shower surround, as the hot water and steam will keep the sealer from staying on for long periods.
  • It does not clean grout, or kill mold, bacteria, limescale, or mildew.

Final Verdict

This is a great product and one that I would recommend keeping around the house. However, if you have not sealed your tile floors before with a grout sealer, it may be a good idea to find a grout and tile cleaner before applying this product. Although it is great at making your grout appear white and bright, it will not kill any bacteria or mold and mildew that is already present.

As far as sealing goes, however, I always keep this on hand and pull it out whenever I notice the grout needs a little freshening up. I can rest easy knowing that the floor is protected from damage that can be caused by these types of bacteria.

Ceramic Tile Pro Super Grout Additive

grout sealer reviews

This product is useful for when you have any cracks or damages in your tile grout. This will replace a sealant, as it is not necessary after use. I wouldn’t completely disregard the use of a good quality sealant just because this product states that you won’t need one after application. This is a good product for when you have damages in your grout, but these cracks and damages will not be all over. You should still use a quality sealant and protectant in the rest of your grout.

This kit comes with everything that you will need to repair any cracks in your tile grout. It can even be used in that are prone to heat and moisture, such as the tile surround in your shower and bath area. Applying the Super Grout Additive will ensure that you will not need any sealants where it is applied. It is waterproof, and guards against future cracking in your tile grout.

This product will work with any color of grout that you have. Everything that you need for application is included in this kit. You will not need to buy any additional supplies.

PROS
  • Any application area will not need future grout products, such as grout sealers.
  • Everything that you need is included in the kit, eliminating the need for expensive tools.
  • Will match your grout regardless of the color.
  • No future maintenance is needed on the application area.
  • Easy to use, with clear instructions on how to apply.
CONS
  • Not a viable option if wanting to use simply as a grout sealer for a large area.
  • A great quick-fix repairing product, but I have found is not a viable option for all of your areas that are needing treatment and sealant.

Final Verdict

This is a great product, but it is one that I like to think of as similar to a band-aid; it should only be used for areas that the grout has cracked or been damaged. It is not a very good option for larger areas, and should not be used as a grout sealer. The only exception to this is in the tile surrounding a bathtub or shower, as it is waterproof and will hold up quite well.

As relates to damages in the grout such as cracks, it is a fantastic product that does just what it was designed to do: repair. However it is not a great product for preventing future damages.

AQUA-X Grout Sealer

This particular grout sealer comes in either a 1-quart or 16 oz container, which is great. This will keep your grout looking natural and there will not be that overly-glazed look that a lot of grout sealers have. This will increase the durability of your grout, and prevent it from getting damaged; while discouraging the growth of mold and mildew. Due to the moisture barrier that comes with the Aqua X grout sealer, you can easily rinse or wipe off any dirt and grime that appears on tiles and grout.

There is no unpleasant odor smell when applying this product, and no lasting shiny appearance. Lasts up to 5 years before needing to re-apply, and covers up to 75 square feet per 16 oz. Can either purchase as a refill for the 16 oz spray bottle, or use with your spray bottle of choice.

I am always looking for something that will maximize my budget, and this does that no problem. I have used it for numerous projects in the past, and it has never failed to impress me. It is a quality product that I have used for multiple large projects, and it has held up without the need to re-apply. I also have never had an issue with dirt, grime, mold, mildew, or soap scum building up over the years.

PROS
  • Great value for the cost of the product; covers a wide area, and lasts as long as promised by company.
  • Does not keep the tile floors looking wet, or overly glazed as some similar products have done in the past.
  • Protects grout from damage, and wipes off the tile with ease.
  • Has no harmful chemicals or odor from use that linger.
  • Is easy to apply and lasts up to 5 years before needing another application.
  • Does not darken or change the color of your grout.
CONS
  • Not recommended for use in areas around the pool, and is especially discouraged from use for submerged tile and grout.
  • Does not glaze the tile, which in some cases can be a downside; depending on the type of project that you are needing.

Final Verdict

This has been a great product that I have used multiple times in the past. The chemical composition of this product works exceptionally well for grout and wipes off of the tile with relative ease; keeping your floors looking exactly the way that you were intending. Unlike other products that are designed for grout sealing, this one, will not leave an unpleasant odor or residue in your home. It is very easy to apply and lasts a long time.

Black Diamond Stoneworks Ultimate Grout Sealer

This is another excellent product brought to us by Black Diamond. There are multiple size options to choose from when purchasing. There is sure to be one that will be just right for the project that you are currently working on. This is extremely easy to use and long lasting, which eliminates the need to use other products in addition to this one. Water based and has a low odor, this will also protect against staining from products such as oil and coffee. In addition to sealing your grout and repelling stains, this product can also be used to clean your grout; which is great for first-time use.

The product goes far and can last a long time; making the need to constantly re-apply null and void. You can apply this to the grout without any expensive tools; simply use a soft cloth to apply and wipe the surrounding tile area down. It does not stay on the tile, so there is no worry about over-applying or ‘glazing’ the tile. This product will work as both a cleaner and a sealant, so you only need to use this product. An occasional mop and bucket may be used in-between, but the grout should remain clean and looking fresh.

PROS
  • Using this product can be a “one-stop-shop” for you grout; it does a great job of both cleaning and protecting the grout from damage.
  • Is easy to apply, and does not require any other products or expensive tools.
  • Long-lasting and free of offensive odors, or harsh chemicals.
CONS
  • In some cases, the sealer can last shorter than others; it is always a good idea to clean the area with a wet rag before use.
  • Compared to other sealers, it can take a while to fully set up.

Final Verdict

This is a great product that will both clean and seal the grout surrounding your tile. Although it does take some time to set up, it is not an inconvenience in any way. It will last a fair amount of time and is very easy to apply; without the need for other chemicals or expensive tools. One of the great things about this product is that I can replace it with my normal cleaning product for my tile floors, and when I use it to clean it seals and protects the grout as well. A product worth looking into.
