5/5




If you’re working in an area with natural, porous stone then you might be in luck with Aqua Mix Sealer’s Choice Gold. This grout sealer is meant to be applied over both grout and natural stone tiles and finishes off with a no-sheen look that maintains both the stone and mortar exactly the way you found it.

This is a penetrating sealer which means that you should only have to lay down a couple of coats and you’ll be good to go for a decade or more. This can help to offset the high cost when you figure in the maintenance required for non-penetrating seals which must be removed in between applications.

Since it also works on stone it’s a pleasant alternative to having to work with different products to keep granite, travertine, and other expensive tiles from eroding over time.

Pros and Cons

  • Good on stone and grout
  • Maintains natural finish
  • Expensive

2. Best Heavy Duty

4.5/5




If you’ve got tiles that are already taken care of, say porcelain or other sealed tiles, then StoneTech’s heavy duty product might be what you need. This penetrating sealer isn’t made for stone like many others, but it makes up for it by being designed specifically to handle grout.

This is one of the toughest sealants you’ll be able to find, and the fact that it costs quite a bit less than many of the other products on the market is a bonus. It does take quite a bit of work to lay down, however, since most people recommend laying down three to four liberal coats of the chemical.

That said, once it’s applied to the grout you’re in good hands. It’s a long lasting, tough sealant that will keep things clean and tidy for a long time to come.

If you have sealed tiles already and you need something heavy duty to take care of your floors or shower walls, this product offers one of the best price to value ratios we’ve ever seen.

Pros and Cons

  • Long lasting and tough
  • Perfect for grout in all areas
  • Not designed for porous tiles

3. Best Budget Option

Aqua Mix Grout Sealer Dual

Product Rating
4/5



This non-penetrating sealer is perfect for a wide variety of applications, coming in with a design which is made to be both oil-phobic and hydrophobic. This means it should easily handle most of the common spills and stains which happen in the kitchen or dining room.

It’s also usable for both interior and exterior applications making it a great all around product for wherever you might have laid your favorite tile within the home. Each quart bottle of this is supposed to be good for about 200 square feet which is pretty standard when it comes to sealers.

It’s cheap and effective, but you may want to opt for a penetrating sealer if you’re working in the bathroom. Many people have found it to be effective in that instance as well, but the risk of mildew after chipping with a non-penetrating sealer can be a turn off.

This cheap and effective grout sealer is super effective for a wide variety of applications, but we’d recommend something else if you’re working in the bathroom.

Pros and Cons

  • Low smell
  • Easy to apply
  • Doesn’t change grout color
  • Not specific for water

4. Best for Marble

Tuff Duck Granite

Product Rating
4/5



This is a great, non-acidic penetrating sealer which works equally well on both stone and your grout. For niche usages it’s great, and it provides a protective cover as well as resisting both water and oil based stains.

The non-acidity of this compound is important, as it allows it to be used on marble as well. It might just be the best around for taking care of marble floors, but when it comes to taking care of grout it’s no slouch.

There is one oddity about it however, which is the lack of longevity for a penetrating sealant. This means it’s a bit higher maintenance than most of our recommended sealants, but it works absolutely fantastic while it lasts.

If you have marble floors, or don’t mind having to reapply things every five years or so instead of the usual ten for a penetrating sealer, then Tuff Duck has your back.

Pros and Cons

  • Usable with marble and porous stones
  • Resists just about everything
  • Lack of longevity

5. Great Option

Miracle Sealants 511 QT SG

This penetrating sealant comes highly recommended by contractors and novice DIYers alike and it has the ability to handle just about anything. One of the best parts is the fact that it dries off completely and leaves a surface you can feel.

There’ll be no doubt that this sealant is at work once it’s been applied. However, the changed texture certainly isn’t to everyone’s taste so keep that in mind before you jump on it.

This one is also oil based, so grab a bottle of mineral spirits to clean up the excess when you’re done and avoid any problems that might arise with it being overly applied.

Best applied with some care, this product is perfect for the ultimate in protection if you don’t mind the fact that it will significantly change the texture of most surfaces it’s applied to.

Pros and Cons

  • Superior protection
  • Easy to apply
  • Changes the texture of surfaces quite a bit

What is Grout Sealer?

Simply put, grout sealers protect the porous surface of the adhesive between your tiles. Since the stuff which holds them down, grout, has a bunch of micro holes in the surface it has a tendency to discolor over time which can leave things looking gross even if you go over the whole surface with bleach and a tooth brush.

Don’t let anyone trick you into thinking you need it to maintain the longevity of the tile surface you’re working with, however, this is purely a cosmetic issue. It’s a pretty rare surface that will regularly be covered in the kind of acidic conditions required to really mess with the mortar in your grout.

The thing is, grout consists of sand and mortar and the sand allows micro-gaps which will absorb anything it comes into contact with them. Over time this will discolor, most of us have seen a gross public restroom with yellowed or even brown grout and it’s caused by a lack of sealing.

When Do I Use a Grout Sealer?

What Type of Grout Sealers Are There

If you’ve just laid down your tile, then investing in a grout sealer is an awesome idea. This will keep the colors true for a long time, as long as you remember to keep applying it when it wears off.

It’s most important in applications that will be seeing a whole lot of liquids like showers and even bathroom floors. The idea here is to keep things looking neat and clean instead of aging out over time and making for an uncleanly look.

It can also help to lower maintenance time. Cleaning grout by hand can be done, but it’s tedious and not perfect. With the right sealer laid between your tiles you can cut down on this time by a lot and a simple sponge and wash job will usually be sufficient to take care of the whole mess.

The only time you don’t need to use it is if you used epoxy based grout. In which case it’s naturally fluid proof. This is generally only used in commercial, high traffic settings and in places where the tile is likely to be exposed to harsh chemicals, it’s really not the sort of thing which is commonly found in the home.

What Type of Grout Sealers Are There?

There are two main types of grout sealing products available, and it’s pretty easy to figure out which one is ideal for you.

Penetrating sealers get into the pores in the grout. This makes for a long lasting, but not permanent seal. If applied as soon as you get things laid down, it can also help to prevent mold and mildew from ever appearing in the pores between your tile. Keep in mind penetrating sealers will also tend to darken the shade of the grout they’re applied to.

Penetrating sealers generally last for ten to fifteen years with proper maintenance applied to them. You will have to strip the grout and reapply it once it has faded, however, since you can’t just apply another coat.

Non-penetrating sealers are laid down as a semi-permanent overcoat. They work great for repelling water and other fluids, but they will discolor over time. This is opposed to penetrating sealers which simply wear out. These sealants need to be watched over time for chipping in order to prevent nasty growth in the grout.

For the most part, they’ll last for three to five years before needing replacement, barring some catastrophe. At the end of this you’ll have to strip up the old sealant and lay down another coat, which is time consuming but certainly faster than having to refinish the entire floor surface.

Acrylic non-penetrating sealers last longer but are much harder to remove. They serve as a good middle ground between the two types of sealer, despite their lack of penetration.

For a new floor it’s up to you to decide which option is better, we recommend penetrating sealer if you’re on the fence however. It’s lower maintenance in the short term and serves as a mostly permanent barrier against mold and bacteria, as well as discoloration.

How to Pick a Grout Sealer for You

You’ll have to figure out where you’re using your sealer in order to make sure that you have the ideal one for a long lasting solution. It basically comes down to one question and your personal budget

Oil or Water Resistant?

Due to the properties of oil and water, it’s a pretty rare sealer that will reject both equally well. While there’s bound to be some cross over, this is a pretty easy choice to make.

For kitchens use an oil resistant sealer. You’re far more likely to spill cooking oil or drop a pan full of butter in the kitchen than you are in the bathroom, and oils will penetrate and discolor grout if they break the seal.

For bathrooms and general use, err on the waterproof side. Spilled drinks are common in other places of the house, and in bathrooms particularly you’re looking at a significant amount of water. If you enjoy hot showers, you’re also looking at steam penetration. On the floor it’s not a big deal, but higher up there can be issues there.

Color Sealing

There are also sealants which can add color to your grout. If you’re looking for an extra, aesthetic flair in the room then they can be great but they generally only come in a non-penetrating type. If this is the case do not sacrifice durability for a bit of extra color. It might cost more, but get the best sealant you can afford no matter what.

Conclusion

Colors may fade, but discolored grout is something which will cause a whole mess of serious problems farther down the line.
