The 9 Best Stone Sealers – Reviews 2020

1. StoneTech D14924225 BulletProof Sealer – Best Overall

StoneTech

The StoneTech is great for natural stone and grout. This one-quart container is fairly pricey but provides the user with long term results and a physically enhanced exterior. Stone that has been treated with this product tends to be tougher, and less susceptible to dirt, grime, and other contaminants.

The solution is rated to work for up to five years, and there is enough in the container to treat a one hundred square foot surface with ease.

For buyers with a little bit of money to spend, this will be a great product.

Pros
  • Lasts for five years
  • Very durable
  • Resistant to dirt and grime
Cons
  • Pricey

2. Stone Care Stone Sealer and Protector – Best Value

Stone Care International

The Stone Care International package is the best stone sealer for the money. For a great price, you get a spray style applicator in an easy-to-use, 24-ounce bottle.

The sprayer can be used easily in an area of up to 72 square feet, and the materials are non-toxic, which makes it great for kitchen countertops.

Buyers should bear in mind two things. First and foremost, this is a smaller container, which means that you may not be getting the most bang for your buck. It is also worth bearing in mind that spray applicators tend to be a little less thorough tan brush style units.

Big deal? Not exactly. You don’t always need the saturation of a brush applicator. Still, it is something to keep in mind.

Pros
  • Affordable
  • Easy to use
  • Non-toxic
Cons
  • Small container
  • Not as thorough as some units

3. Black Diamond Stoneworks Stone Sealer – Premium Choice

Black Diamond

The Black Diamond Stoneworks is a glossy style option that is made to be used outdoors. The materials are toxic, but they are also very heavy duty.

Consequently, stone treated with this solution will be more resistant to wear and tear. It will also be fortified against tougher waste, such as oil.

This is one of the more expensive sealers on our list today, but the size of the container makes up for the cost somewhat. This is a gallon-sized unit, which should last for a good deal of time.

Pros
  • Heavy duty
  • Gallon sized container
  • Very durable
Cons
  • Pricey
  • Toxic materials

4. Rocklinite Labs Tuff Duck Stone Sealer

Tuff Duck

Rockinlite Labs Tuff Duck Stone Sealer is good for grout and natural stone. The container is a twenty-four-ounce package that features an easy to use spray style applicator.

The manufacturer advertises that the bottle can treat a surface of eight hundred square feet, though, in reality, it will probably depend on where you are applying it and how thorough you want to be.

This solution can be used both indoors and out and is rated to last for five years. You may want to keep in mind that it tends to discolor darker materials. If you have rich colored stones, you may want to look for a different sealer.

Pros
  • Easy to use applicator
  • Eight hundred feet of coverage
  • Five-year expectancy
Cons
  • Discolors dark stone

5. Aqua Mix Sealer’s Choice Gold

Aqua Mix

The Aqua Mix is good for buyers on a budget. It is a moderately priced 32-ounce container that is designed to deliver a very natural look. Rather than delivering a glossy or dark finish the way some sealers do, this unit tries to keep your stone looking as natural as possible.

It is an alright way to treat a relatively large space, but buyers should note that this is not as effective as some of the other products on our list. It tends to let in more contaminants than other sealers.

Pros
  • Affordable
  • Natural finish
Cons
  • Not as effective as other sealers on the list

6. Granite Gold GG0036 Sealer Spray

Granite Gold

Granite Gold is a non-toxic spray style sealer that is great for indoor use. Being only 20 ounces, you may not use this unit for larger surfaces, but it will be great for kitchen counters.

The material is non-acidic and does not use any of the harsher chemicals associated with a stone sealer. This is an odorless solution that enhances its indoor application, but it also is not very powerful. Contaminates and stains will still accumulate on the top of the stone which may be counter-intuitive to some user’s intentions.

Pros
  • Odorless
  • Easy to use
  • Non-toxic
Cons
  • Not as powerful as some other sealers

7. MasonryDefender Stone Sealer

MasonryDefender

The MasonryDefender is a much more generalized sealer than most of the other units on our list. In addition to being good for natural stone, it can also be used with bricks and concrete.

This one-gallon container is relatively affordable and designed specifically to waterproof the surfaces that it treats. That being the case, it will be a great way to “winterize” outdoor stone material, keeping it fortified against the freezing temperatures of winter.

If you are looking for something that will enhance the appearance of your stone, this won’t be for you. However, if you need some genialized protection, MasonryDefender might be the right way to go.

Pros
  • Affordable
  • Versatile
Cons
  • Not good for cosmetic purposes

8. Miracle Sealants Porous Plus Sealer

Miracle Sealants

The Miracle Sealants Plus is an outdoor solution that is designed to protect against water and oil. It is resistant to weather and will also be able to withstand UV rays from the sun.

The manufacturer advertises that this solution will be able to make stone materials less slippery, though we can’t verify these claims.

Ultimately, it is a good, moderately effective sealer for people looking for an outdoor product. That said, you will want to keep in mind that this is one of the more expensive options on our list.

Pros
  • Great for outdoor use
  • Fortified against rays from the sun
Cons
  • Not as effective as advertised
  • Fairly pricey

9. SimpleCoat Natural Stone & Stainless Steel Sealer

SimpleCoat

We close the list out with an organic, non-toxic solution. The SimpleCoat Natural is designed to be used both on stone and on stainless steel, making it one of the more versatile options on the list.

This is a spray style applicator that can be used very easily. It is great for people that want a really natural product, but there are some issues. The biggest issue is one of value. This is only an 8-ounce container, but it is more expensive than some of the gallon-sized units that we looked at.

It’s also limited in its effectiveness. You will still experience dirt and contaminates. It also won’t have a major impact on the cosmetic appearance of the stone that you treat.

For people that are all about the organic life, this will be an avenue to explore. For everyone else, there are much more cost-effective choices on the list.

Pros
  • Organic
  • Non-toxic
Cons
  • Limited effectiveness
  • Very pricey
  • Small quantity

Buyer’s Guide

And now, here are some buying considerations that will help you choose the best stone sealants on the market.

First, does all stone need to be sealed?

Short answer, yes. All stone is porous. If you are dealing with authentic materials it means that they will be extremely vulnerable to some level of seepage.

However, not all stones are the same. Depending on the materials you are working with, you may need to seal often, or only on very rare occasions. In any case, it is always important to have a robust understanding of the medium that you are working with to be prepared to give it the protection it needs.

Multifaceted

When it comes to a good stone sealer, the best product will give you plenty of value. Higher-end products can provide a sophisticated level of protection against a wide range of different contaminates.

For the best results possible, select a stone sealant that advertises on its ability to protect against factors such as stone erosion, water seepage, and even staining.

If you choose the right product, you will get something that not only protects your stone but also makes it easier to clean and maintain over time.

Know What the Sealer Will Do to Your Floor

This may sound a little obvious but it is important to be aware of the effect that the sealer will have on your floor. While the general point of most sealers is, in part, to enrich the appearance of your stone, the actual texture may also change depending on the product you use.

Most sealers produce a “wet’ look and feel on the surface. This can affect the slipperiness of the floor.

However, if you are applying a sealer to a bathroom floor (or any area that experiences an excessive amount of water particles) you may instead opt for a sealant that actively decreases the slipperiness of the floor.

Application Style

There are several different ways that you can apply your stone sealer. You can rub it in with a cloth or a brush or you can also use a spray bottle like you would with Windex.

Application style does not necessarily shape the impact of the solution, but it certainly can shape your user experience. For example, many people may find that a spray bottle is more user-friendly than a brush system.

Location

The location of the stone also matters. For example, if you have stone kitchen countertops, you will want to be absolutely positive that the sealant you use is non-toxic. Toxic materials can transfer over in the food preparation process.

You will also want to account for the substances that are most commonly encountered in a kitchen setting. For example, countertops may run into wines, oils, and other food particles. Certain sealers will be better than others at repelling those contaminants.

Similarly, if your stone is located outside, you will have a different set of issues to worry about. In that case, you may not need to worry so much about toxins. You will, however, want to account for the added wear and tear that outdoor materials experience.

Clarity

We talked earlier about how you can get sealant that makes your stone look rich, darker, or even wet. You can also get sealants that facilitate a shinier, glossy finish.

Neither is necessarily better than the other. It is mostly a matter of taste. In any case, understand what a sealant will do before you apply it to your floor.

Quantity

When it comes to determining the value of a given package of stone sealant, the quantity will be the most important determining factor.

Bigger packages will cost more money, but they may increase the value of the unit. You may not need a ton of sealant all at once, but eventually, you probably will. Stone lasts a long time, and it needs to be resealed often.

Price

The nice thing about a stone sealant is that it is never extremely expensive. Some units are, of course, more expensive than others, but in general, there isn’t a sealant in the world that will break your bank.

This being the case, even people who ordinarily buy for bargain might find it worthwhile to invest in a high-quality choice.

Doing so won’t wreck your savings account, and you will be treated to an enhanced user experience.

Conclusion

As you have probably observed from our stone sealer reviews, there are many options. All of the products on this list are good for someone, but which one will be right for you? Our top choice, the StoneTech D14924225 BulletProof Sealer will be great for buyers that want the best product they can get their hands on.

However, if you want to snag a good deal, you can find it in our runner up choice, the Stone Care International 5187 Stone Sealer and Protector.
