Carl Anders from Tilersplace.com

Hi there and welcome to Tilersplace.com

My name is Carl and I have been tiling professionally for over 20 years in both the USA and England.

In that time I have sealed my fair share of grout, natural stone, cement tiles and I’ve used some great and some not-so-great grout sealers in that time.

Today, I want to pass on my experience with grout sealer’s on so that you can make the right and proper decision when selecting one for your project.

3. Miracle Sealants – Seal & Enhance Grout SEaler

Miracle Sealants has outdone themselves with this color enhancing natural stone and grout sealer.

Unlike other grout sealers in this buyer’s guide, Seal & Enhance Sealer aims to bring out colors by adding a “wet-look” and sheen to them.

This is done with the aid of solvents, making it a thicker and heavier tile sealer which works brilliantly for natural stone.

I use this product before working with unsealed tiles to prevent any grout and adhesive staining the stone alongside giving the surface a beautiful and deep shine.

It’s also rated for interior/exterior use and freeze/thaw resistant.

Pro's

• Heavy penetration and stain resistance

• Add’s instant beauty and depth to natural stone

• Long-lasting protection in all conditions

• Easily one of the better color enhancing sealers out there.

 

Con's

• Solvent-based = Very strong smell

• Can cause hazing if the surface is not fully dry.

• Darkens grout by a shade

4. Tuff Duck – Natural Stone Sealer

Tuff Duck is a lesser known name but that in no way makes it’s Natural Stone Sealer a lesser product.

Tuff Duck excels at sealing Marble tiles and countertops without affecting the natural color or leaving an undesired gloss coat on top of it.

On top of being able to work on all natural stone and tile, it can also be used on concrete and various forms of unsealed tiles like terra cotta and terrazo

Wide variety of applications

• Cheaper than other sealers

• Can’t be used on cement

 

When Do I USe A Grout Sealer?

A grout sealer works well in a bathroom.

The purpose of a grout sealer is to prevent water and any other external matter from staining or penetrating the grout or tile it is used on.

On a normal porcelain tile, that job is taken care of by the glaze, or that beautiful shiny part on the surface of the tile that is the pattern.

Your tile grout, however, is not impervious to water, mold & mildew and the worst of them all – red wine!

The same applies to all natural stones like granite, sandstone, marble, travertine.

These natural tiles are porous by nature and do not come sealed from the factory. Meaning that they 100% require some sort of sealing prior to installation in order to prevent any cement staining and dust build-up that will occur during tiling.

So to translate this into terms you want to hear:

If you are installing natural stone tiles or counters in your home, you require a quality grout sealer to prevent any oil and water based stains, easy cleaning and maintain the finish of your expensive stone.

To achieve a natural look: Use Aqua Mix Sealer’s Gold

To achieve an enhanced color, always wet look: Use Miracle Sealants Seal & Enhance

If you did not use Epoxy Grout in your tiling installation and are wanting to maintain the look of your grout color, prevent mold & mildew build-up and make tile maintenance a breeze, then you require a grout sealer.

What IS A Grout SEaler?

the best grout sealer on disply

I have seen some pretty horrific explanations of what a grout sealer is on similar grout sealer reviews so I will try to explain it properly.

A grout sealer is a water or solvent based solution that is designed to create a protective layer between grout/tile and external dirt, stains and liquids.

This is achieved by using polymerized silicone resins and additional polymers that penetrate the porous surface of tile grout and tiles and create a barrier against external forces while still allowing the natural color and texture of the protected surface to show through.

The water or solvent that carries this resin is there so you can easily apply the grout sealer and allow for penetration of the surface and all of its numerous cores. With time, the carrying agent evaporates into the air and leaves only the resin behind.

“This is why multiple coats of a grout sealer are needed; because one coat of grout sealer is not enough to fully cover an area and create a thick enough layer that will endure living conditions and stains as the protective agent is diluted with the liquid based carrier.”

In Layman’s Terms:

A grout sealer is a magical liquid that enters tile and grout and protects them against everything. It goes on wet and dries up and your grout is sealed.

How Do I Use A Grout Sealer?

To use a grout sealer you will require an applicator to apply the grout sealer and a clean surface to work on.

Depending on the scale of work you can either use a mini paint roller for sealing tiles or a sponge pad and a specialized grout sealer applicator bottle for grout sealing. A soft haired paint brush can also be used.

The best grout sealer for color enhancing is 511 Seal+Enhance

Lastly, you will need a clean cotton rag or paper towel to wipe away any excess solution that gets onto your tiles or surfaces that you do not want sealed. 

If you are wanting to seal old tile grout or tiles, you will need to thoroughly clean them first with a brush and cleaning solution.

Grout-Eez is one of those miracle products that combined with a proper scrubbing brush, will clean your tile grout and get it ready for sealing.

Remember to always do a spot-check first to ensure no undesired changes occur on your tiles or grout.

Once cleaned, give atleast 12 hours for everything to be fully dried.

Grout Cleaner

If you are sealing newly applied grout, give at least 48-72 hours for the grout to fully cure and dry out properly.

How To Apply Grout Sealer In 3 Quick Steps:

Step 1: Apply your chosen grout sealer to the surface using your applicator of choice. Aim to go in one direction only to remove smudge marks and build-up of product. Try to cover 100% of the surface. Remember to apply a thin coat.

Step 2: Allow the product to sit on the grout for at least 5 minutes and then use a clean rag to buff away any excess left on the tiles. If you are sealing natural stone, you will likely skip this step as the grout sealer would have fully penetrated the surface.

Step 3: Wait atleast 30 minutes and apply a second coat of grout sealer to the surface. After the second coat, wait for 2 hours and test if water penetrates the surface. It should bead up and not soak into the tile/grout. If it does, apply further coats untill desired result is achieved.

How To Seal Grout Guide

Grout Sealer F.A.Q

“The only silly question is the one unasked” and so I want to answer all the most common questions asked about grout sealers and their use.

If your question is not answered, please leave a comment below! I’ll answer it to the best of my knowledge and your question might be featured in an updated version of this Grout Sealer Buyer’s Guide 🙂

What is the best product to seal grout?

The best product to seal grout is Sealer’s Gold Choice by Aqua Mix. It effectively penetrates all forms of sanded grout and applies a protective film over it that stops staining and helps retain the grouts color.

For more porous grouts or large sections of grouted areas like a pebbled shower floor, Porous Plus Sealer by Miracle Solutions is the best grout sealer for the job. It excels at protecting highly porous materials with its resin that remains close to the surface, battling stains before they penetrate the pores.

Is it necessary to seal grout?

No, it is not necessary to seal grout if you don’t want to. Your grout will still carry out it’s duty but it will be more susceptible to staining, loose color uniformity and be harder to clean as a result.

Also, if you have epoxy grout, it is not necessary to seal it, nor is it recommended to even attempt this. Epoxy grout is nearly 100% waterproof and will not absorb your grout sealer.

Should sanded grout be sealed?

Yes, you should seal sanded grout as it is highly porous and allows water to penetrate it. Especially if you are wanting to retain the color and prevent mold and mildew building, you should be sealing sanded grout with a quality grout sealer that is formulated for sanded grouts. Sealer’s Gold Choice by Aqua Mix is suitable to seal sanded grout.

How do you seal porcelain tiles?

Porcelain tiles do not require sealing as they come with a factory glaze that is 99.9% waterproof and do not allow water or anything to penetrate it.

There are, however, some forms of unsealed porcelain tiles that could benefit from a light coat of a tile sealer. These tiles are very rare and you’ll be warned of this from the tile seller upon purchase.

How long do you have to wait to seal grout?

Allow new grout to cure for at least 48 to 72 hours before sealing. This is to ensure the grout reaches full strength and is fully dry. Old grout installations should be cleaned thoroughly before sealing and inspected for any cracking, or loose areas before applying a grout sealer.

What is the best grout sealer to use on shower floors?

The best grout sealer to use on shower floors is Sealer’s Gold Choice by Aqua Mix. It is a high quality, penetrating sealer that will repel and bead up water. Sealing a shower and shower floor is recommended as it will ensure the tile grout will retain its color and allow for much easier cleaning over the long-term.

How long does grout sealer take to dry?

Grout sealer takes 24 hours to dry and cure properly. If you are using grout sealer in a shower, it is best to wait longer (36 hours) to ensure the grout sealer has dried out properly in all sections of the shower. For best results, check the label on the product you are using.

How often do I need to apply grout sealer?

Grout sealer should be applied once a year to tiles and grout in high traffic areas like showers and kitchens. This is to ensure an even coat of grout sealer is present in the surface at all times and no patches of dirty grout appear over time.

While manufacturers claim their products can last up to 10 years, the reality is once a year at least. Reapplying grout sealer once a year will ensure the best results.

Grout Sealer Conclusion

In this best grout sealer buyer’s guide we took a look at the best sealers for all types of tile and grout and took a look into what a grout sealer is and why you need to use one.

Overall, the Sealer’s Choice Gold grout and tile sealer was the best all-round sealer as it offers a universal scope of applications and delivers a professional result.

There are no doubts about why I use this product most frequently in my daily tiling work as I can rely on it to deliver the results my clients expect without requiring excessive coats.

It is a tad more expensive over regular grout sealers however in this game, you get what you pay for. A cheap grout sealer will require more coats and deliver a lesser result so a few pennies saved today will cost more in maintainance in the long run.
