Grout Sealer Question – When Do I Use A Grout Sealer?
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. Its best to get them sealed with a quality natural tile sealer before any work is done.
These natural tiles are porous by nature and do not come sealed from the factory. Meaning that
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 sealant 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.
Grout Sealer Question – What Is A Grout Sealer/Grout Sealant?
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 best described as a water or solvent based solution that is designed to create a protective layer between grout/tile and external dirt, stains
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.”
What Is A Grout Sealer In Layman’s Terms:
A grout sealer is the best solution against grout staining. It 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/Grout Sealant?
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. I found the paint roller to be the best grout sealer applicator.
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, its best to give
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 that best fits your needs 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: It’s best to wait

Grout Sealer F.A.Q – Grout Sealer Help
“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 🙂
Question: Is it necessary to seal grout?
Answer: No, it is not necessary to seal grout if you don’t want to. Your grout will still carry out
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.
Grout Sealer Question: What is the best product to seal grout?
Answer: The best product to seal grout is AQUA-X Grout Sealer. It effectively penetrates all forms of sanded grout and applies a protective film over it that stops staining and helps retain the grouts
For more porous grouts or large sections of grouted areas like a pebbled shower floor, your best bet is 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.
Grout Sealer Question: Can I Grout Natural Stone With Epoxy Grout? Will The Grout/Tile Sealer Protect It?
Answer: Generally, the answer is no. All natural stone tiles are created/treated differently and have various degrees of porosity. Highly porous stone can absorb the epoxy grout resin through the edges of the stone tile, leaving a picture frame effect where the outer edges are darker. This color change is irremediable and will stay there for the life of the tile. If you want to use epoxy grout on natural stone, its best that you apply a quality tile sealer to all sides of the tile before installation and test it first before proceeding. Without prior testing, you may end up with a multi-thousand dollar tile installation that is ruined forever.
Question: Should sanded grout be sealed?
Answer: Yes, it is best practise to seal sanded grout as it is highly porous and allows water to penetrate it. Especially if you are wanting to retain the
Question: How do you seal porcelain tiles?
Answer: Porcelain tiles do not require sealing as they come with a factory glaze that is 99.9% waterproof and
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. Its best to ask the salesperson while buying your tiles if you are unsure.
Question: How long do you have to wait to seal grout?
Answer: The best practise is to 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.
Grout Sealer Question: What is the best grout sealer to use on shower floors?
Answer: The best grout sealer to use on shower floors is AQUA-X Grout Sealer. It is a high quality, penetrating sealer that will repel and bead up water. Sealing a shower and shower floor is recommended and best practise as it will ensure the tile grout will retain its
Grout Sealer Question: How long does grout sealer take to dry?
Answer: 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.
Question: How often do I need to apply grout sealer?
Answer: A grout sealer provides the best results when 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
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.
Best 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 AQUA-X grout sealer was the best all-round sealer as it offers a great range of features in a very easy to apply solution.
Since trying out this product it has become my favourite grout sealer and one I will recommend to future clients and readers of this website. It’s so easy to use and provides an excellent result.
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 maintenance in the long run. Just use the best and ignore the rest.
Hats off to Black Diamond Coatings, this product is a game changer.
Hi Carl, thanks for the easy to follow guide on grout sealers. I have purchased some patterned cement tiles for my patio and was told I need to seal them. Would the Aquamix sealers gold be alright to use on them? Im sure you have said that you can but i’d like to be sure. Thank you.
Hi Susan,
Yes, the Aqua Mix Sealer’s Gold Choice is a suitable sealer for those types of tiles. You can also use it to seal your grout after the job is done if you wish. Remember that this is a natural look sealer that won’t leave a sheen on the tile, for that type of tile, I reckon it’s ideal.
