How To Apply Grout Sealer
1. As I mentioned, above, its critical that your grout is dry and has cured enough. Wait at least 48-72 hours after the grout was applied. . Its ideal to do this within the first 2 to 3 weeks. Note: If youve been using the shower, you want to wait at least 12 hrs before applying .
2. Tape off any wood baseboards or cabinets that are in the area. You want to avoid any unintentional staining or deposits.
3. Apply the sealer to the grout lines. You can use a foam paint brush, a small roller or a paint pad. Start in one corner and systematically cover the grout joints completely. Its best to work at a far corner so you can walk your way out of the room.
Systematically apply the sealant in a smooth, even coat over each part of the grout, taking care to completely cover every corner of the joint. Since you dont want to accidentally miss a grout line or joint, it is best to follow a consistent left-to-right pattern to ensure nothing is missed.
You want to avoid getting the sealer on the tiles, so its better to go slowly. If you do get sealer on the tiles, dont worry about it just use a rag to wipe it off quickly. Most people find it easier to just do a few feet at the same time both to wipe as well as avoid the need to wipe. Youll want to remove sealer from the tile before it starts to dry so that youre not left with a foggy film thats nearly impossible to remove.
4. Wait 5 to 15 minutes to allow the first coat to soak into the ground.
The Only Grout We Ever Use
If youve got a tiling project in your future , remember, bookmark, voice memo, tattoo, or do whatever you need to do to remember Mapei Flexcolor grout.
I know this sounds like Im overreacting, but take it from people who have grouted 7 bathroom floors, 3 showers, 3 mudrooms, and 2 backsplashes in the last two years: this grout has been life-changing. And no, this is not sponsored by either Mapei or Floor & Decor, which is where we typically buy ours .
floor tiles: pink, white, and taupe
I meant to proclaim our love for this grout after finishing the beach house tiling two summers ago but we got sucked into the duplex and, well, this post never got written. But the duplex tiling just gave us more time for our romance to blossom, so I wanted to tell you why this has become THE ONLY GROUT we ever buy & use. We are going on 2+ years of not buying a single other type of grout . Even our contractor swears by this stuff. Thats actually how we found it.
So Im going to just dive into all the whys of that very big statement about grout and Im also going to toss in some tips for picking the right grout color and my new trick for minimizing grout haze while Im at it.
Ing Tip: Minimizing Grout Haze
Now, this Mapei grout doesnt seem to leave more or less grout haze than any of the other grouts weve used . And grout haze is one of my least favorite things in the world because its like the LAST THING I want to spend time on after having survived tiling and then grouting.
So a thing I experimented with in the duplex that worked really well was doing a preemptive tile wipe while the grout was still wet. I dont have any pictures of this, so let me explain.
It only really works with larger tiles, but after I applied the grout with my float and did a couple wipe downs with my damp sponge, I let it sit for another 5-10 minutes and then I used a rag or paper towel to dry just the surface of the tile, being sure not to rub the grout lines themselves. It sounds more tedious than it was, because it really was only one quick swipe and it basically wiped up all of the liquid that would eventually become grout haze.
Again, its really most practical on larger tiles where you can safely wipe the tile without touching the wet grout, but it completely saved me from having to buff the floors or use a grout haze remover after the fact. And you know how much I love to eliminate extraneous steps!
Long story short: next time you tile, grab some Mapei Flexcolor grout and think of me fondly when it makes things easier.

Is It Easy To Apply Grout Sealer
Grout sealer is easy to apply but tedious. The smaller the tile size, the more grout you will have. If you installed small mosaic tile, for example, you’re in for a lot of grout sealing. If you installed a large format tile, your sealing job will be exponentially easier and faster.
This matters because using the brush or roller sealer applicators on an entire roomful of small tile can take up a whole weekend. In this case, try the spray-on type of grout sealer.
Water Vs Solvent Based

Some grout sealers are water-based formulas, while others are solvent-based. Water-based grout sealers offer more surface-level protection and wont penetrate as deeply into porous grout, but they also dont produce as many odors or VOCs as some solvent-based formulas. For deep protection of your grout, however, a solvent-based impregnator-sealer is the best bet since itll fill spaces and protect your grout from deep within.

Should You Seal The Grout In Your Shower
There is some contradictory and misleading information out there. Remember grout is porous, so it absorbs water, as well as whatever is in that water . By applying grout sealer, you are pre-empting water and other products from penetrating the grout.
So, yes, you want grout sealer in the shower and its even more important than other areas because, as I sure you realize, showers tend to get wet and steamy.
The only exception to this is if you have an epoxy grout which naturally blocks the water from penetrating the grout.
What Type Of Grout Sealer To Use In A Shower
There are two types of grout sealers that are often found. These are penetrating sealers and surface sealers. The penetrating sealers will ensure water resistance by creating a layer around the grout. For the shower, this is regarded as the best, but it does not allow the water to dry that is found under the tile that causes mold growth.
Penetrating sealers are more technical and use more formulas to block the grout for preventing it from any moisture and stains. It fills all the gaps that keep the moisture away from it. Universal Grout and Tile Protector give the best quality grout sealers.

What Is The Best Method To Apply Grout Sealer Paint Vs Roll Vs Spray
There are 3 ways to apply grout sealer you can paint or roll it on, or you can spray it on. Painting and rolling is basically the same process, it just depends which type of instrument you prefer.
The brush applicator is more difficult for some because sealer doesnt feed smoothly into the brush and sometimes requires you to go back and reapply in dry areas where sealer failed to apply.
Rollers are not perfect, but many feel they are better than brushes. Sealer remains relatively close to the seam line without slopping too far over onto the tile surface.
Im not a big fan of spraying. It seems like its easier, but its really not. You save some time in the application, but you spend way more time on cleaning the tile and you usually have residue that dries on the tile and it takes a while to get this off . And, because the spraying method is a bit less purposeful, sometimes areas dont get fully coated. Plus, sometimes the spray goes where you dont want it to and Im not crazy about the aerosol and inhaling that. Id recommend brush or roller.

This Grout Doesnt Need Sealing & Is Stain Resistant
Again, need I say more? Probably not, but thats never stopped me before.
tile:
Tiling already has enough steps involved so Im always happy to eliminate one, especially the annoying ones at the end like sealing your grout to prevent stains. This Mapei Flexcolor is somehow formulated to prevent stains so all you have to do is let it cure for 3 days and its good to go .
I should disclaim that its water-based stains that this grout is resistant to and like any stain resistant surface, you still probably shouldnt slather marinara on it and let it sit for days. But were over 18-months in on the beach floors and theyre still looking as good as new. As in, not a single crack or stain. Anywhere. In any of the three bathrooms, the mudroom, the backsplash. Everything looks as good as the day we grouted it. In fact, I took the photo above this weekend, over a year & a half after we grouted just to demonstrate that this stuff goes the distance. Looks like new, eh?

Picking The Right Grout Color
It still amazes me how much grout changes the finished look of any tiling project, so its important to give some thought to the color you choose. If you dont believe me, Emily Henderson did a great post a couple of years ago showing off the impact of your grout color section.
That being said, we use Warm Gray in 85% of our tiling projects. To us, its the perfect neutral grout color that offers enough contrast to the lighter tiles that we choose while still looking great with darker tiles .
backsplash tile / cabinets & counters: Ikea / pink stove & rug: secondhand finds / sconce
And since its so agreeable to so many tiles, you can use it throughout an entire room to help tie your various surfaces together . For instance, in the downstairs bathroom at the beach house we used it on both the shower and the floor. It provides a different type of contrast in each spot but using the same grout helps them work together.
slate-like floor tile / long subway tile
And if you study that photo above, you can see what I mean about how crisp and white it looks when paired with darker tile, without being as unforgiving as bright white grout can be. Thats the same exact grout color everywhere in the picture above although it looks grayer when its next to the white subway tile and lighter when its next to the dark floor tile.
How Does Grout Sealer Work

In the absorbent grout, penetrating grout sealers have proved very useful as they are transparent liquid that completely blocks all the moisture to go under the floor and tiles, and form moisture and mold.
Some sealers are only for stone tiles, and some are for ceramic tiles. The sealers should be picked by the professionals after examining the surface of your floor. These clear sealers are different in their use. Some use polymers while others use water-based solution.

Assessing Whether You Need Grout Sealer
Existing tile will occasionally need a reapplication of grout sealer. Highly trafficked floor tile will need grout sealer applied more frequently than other types of tile applications, such as wall tile. Experts recommend resealing every six months to a year in high-traffic areas. Tile kitchen countertops tend to need more frequent resealing than tile bathroom counters.
The best test is a simple one. Place a few drops of water in your palm, then sprinkle that water at various places around the tile field. Grout areas that soak in water immediately need resealing. Areas where the water beads up and stands on the grout need no resealing.
Is It Difficult To Apply Grout Sealer
No, its easy to apply grout sealer yourself. Its a bit tedious, and takes some time, but even a novice DIYer can easily do this. If my mom can do this, I know you can, too. When you have larger tiles , its pretty easy when you have smaller tiles, then you have more grout lines and it will take a bit longer.

When Do You Seal Your Grout
After youve installed new tile, you want to wait at least 48 to 72 hours for the grout to dry and cure. Your grout should be clean and dry and make sure the grout lines are cracked or chipped. If they are, then touch up the grout and then wait an additional 48 to 72 hours before you start sealing the grout.
Do You Seal The Tiles Too
Generally, no would not seal the tile, assuming that your tile is glazed ceramic or porcelain. If you have unglazed tile/clay or natural stone, you would seal these as they are porous. .
Be aware that you should NEVER apply grout sealer to the surface of non-glazed tile or natural stone. If you do, the tile will absorb it and it will never come out .
If you are unsure what type of tile you have, contact the store that you bought the tile from.

Its Crack Resistant & Shrinkage Controlled
Old grouts that we used to use recommended a special liquid additive in place of water that made it more flexible to help it resist cracking or shrinking. So it was extra money and an extra step. Meanwhile, that feature is built right into this formula, and we have never had it crack or shrink in all of our years of using it which isnt something we can say about the other grout weve used .
