Grout Sealer Question – When Do I Use A Grout Sealer?
The purpose of a grout sealant 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 used in interior surfaces, that job is taken care of by the glaze, or that beautiful shiny part on the tile surface that is the pattern.
Your grout and marble, however, are not impervious to water, mold & mildew and the worst of them all – red wine!
The same applies to all natural stones like granite, sandstone, white marble, travertine. Its best to get them sealed with a quality natural tile sealer before any work is done.
These natural tiles are penetrable 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 surfaces or counters in your home, you require a quality sealant for protection against any oil and water based stains. A sealant product will also save time with 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 grout sealant products are 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 surface coating between grout and external dirt, stains
This is achieved by using polymerized silicone resins and additional polymers that penetrate the absorptive surface of grout and marble 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 joints staining in interior surfaces and outdoors. It is a magical liquid that enters 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 sealant 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 grout or tiles, you will need to thoroughly clean them first with a brush and cleaning solution. Oil, dirt and stains will need to be removed first.
Grout-Eez is one of those miracle products on the market that combined with a proper scrubbing brush, will clean your aging grout and get it ready for sealing.
Its a nice alternative to heavy duty grout cleaners like acid that are difficult and dangerous to use.
Remember to always do a spot-check first to ensure no undesired changes occur on your surfaces.
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 product that best fits your needs to the surface using your applicator of choice. Remember to buy enough to cover the needed square feet of your installation. 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 and avoid vapors due to the toxicity of these products.
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 stone, you will likely skip this step as the sealer would have fully penetrated the surface. (Make sure your product is a suitable granite, grout and marble sealer.)
Step 3: It’s best waiting

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, you may 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 if you don’t want the extra protection. Your grouting will still carry out
Also, if you have epoxy grout, sealing is not necessary, nor is it recommended to even attempt this. Epoxy is nearly 100% waterproof and can not absorb any kind of grout sealers.
Grout Sealer Question: What is the best product to protect grout?
Answer: The best product is AQUA-X Grout Sealer. It effectively penetrates all types of grouting and applies a protective film over it that stops staining and helps retain the grouts
For more pervious grouts or large sections of grouted areas like a pebbled shower floor, your best bet is a heavy duty grout solution like Porous Plus Sealer by Miracle Solutions is the best grout sealant 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 Sealant Question: Can I Grout Stone Tile With Epoxy Grout? Will The Grout/Tile Sealer Protect It?
Answer: Generally, the answer is no. All stone tile are created/treated differently and have various degrees of porosity and inherent protection.. Highly pervious types always requires additional protection as it may absorb the epoxy resin through the edges of the stone, 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 on natural tile, its best that you apply a grout and marble sealer on 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. A solvent based product will generally provide more protection over a water-based sealer as well.
Question: Should sanded grout be sealed?
Answer: Yes, it is best practice to add protection and seal all types of grout as it is highly porous and allows water to penetrate it. Especially if you are wanting to retain the

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.
best grout sealers Question: How long do you have to wait to seal grout?
Answer: The best practice is make sure the new tile grout has cured 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 surfaces inspected for any cracking, or loose areas before applying a sealer.

Answer: The best grout sealer product to use on shower floors is AQUA-X Grout Sealer. It is a high quality, penetrating sealer that will provide protection by repelling and beading up water on all surfaces.

Grout Sealant Question: How long does grout sealer take to dry?
Answer: Grout sealer takes 24 hours to dry, cure properly and provide surfaces protection. If you are using grout sealer in a shower, it is best to wait longer (36 hours) to ensure it 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 and surface protection when applied once a year to tiles and grout in high traffic areas like showers and kitchens. This is to ensure an even coat is present
While manufacturers claim their products can last up to 10 years, the reality is once a year at least. Reapplying 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 available on the market for all types of tile and grout and took a look into what a sealers is and why you need to use one for lasting surfaces protection.
Overall, the AQUA-X solution by Black Diamond was the best all-round sealer for granite, grout and marble plus everything in between. It offers a great range of features in a very easy to apply solution.
Since trying out this range of tile grout sealers it has become my favourite 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 sealers however in this game, you get what you pay for. A cheap product will require more coats and deliver a lesser degree of protection. 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 and their range of tiling protection products, Aqua-X is an excellent addition to the market.
