This was rec'ed by NATCO for sealing grout, but product description doesn't mention that use. We have a subway tile shower and mosaic floor. Thanks!

I used it to seal the grout in my new tile shower about six months ago. So far, so good. I squeegee the shower and dry it with a towel after every use and it still looks like new. I decided to use this as a sealer because I was unhappy with sealers I have used in the past. It was expensive, but so far it seems worth it.

This is the best sealer that DuPont produces and is used for all stone applications, including grout. Any porous stone or grout will be sealed.

I have used it in my shower, but I found that a Clorox bleach pen works better to soak into the grout. This is more of a liquid not a paste and will not stay on the grout long enough from my experience.

This is appropriate for use for setting bowls, fixtures, faucets, sink frames and strainers and I don't think it would be appropriate for this use. It depends on how big the gap is and whether there is anything solid behind the ceramic tiles to keep it from falling through the hole. It would be hard to make a smooth surface with it since you can't push it to take the ridges out of it. The container says "it is specifically designed to make a waterproof seal between any two 'rigid' surfaces". It also says, "Do not use on marble, granite, limestone or any other dimensional stone". I guess you'd have to say whether you'd call your area two 'rigid' surfaces. Sorry I can't be more specific There is also available a Oatey Stain-Free Plumber's Putty to be used on the stones mentioned above.

I used it to seal my marble countertops. With a clean towel, I "damp" mopped it over the countertops. Let it sit for a few hours and then repeated.

Hello-You can certainly seal your tiles with our 511 Porous Plus. But they would only require sealing if they are a porous material. If they absorb/darken when water is applied to the tiles then it would be a good idea to seal them. If they do not absorb water then you should not have to seal them.Thank YouMSCtechnical Support Team

The glass company that is fixing our shower door recommended it for use on the glass door, not sure about tile etc.

This material probably isn't too good for this application. We used it to seal gaps between floor and wall of our building. There was a lingering odor that took months to dissipate.

it certainly worked wonders on my tile floors and walls. used it for just this purpose in the bathroom and kitchen and it worked great. you'll want to use a grout sealer after you have cleaned it for extra protection.

This product is used under tile in conjunction with a mortar bed application. It is not for the tile to be directly bonded to.

I applied it to my travertine floors and grout lines with a sponge. You MUST wear a good breathing mask and have proper ventilation. I cannot stress this enough -- especially if you are covering a huge area. Porous Plus is highly recommended for kitchens. Better protection when working with hot cooking oils (which have been known) to breakdown sealers instantly.

there is no need to use it on ceramic or porcelain tile as they are both made of non absorbent material (they've been sealed by being fired). You only need to use it on the grout.

We never used it for just grout. We have a ceramic tile floor in our kitchen and bathroom. It is the only steam cleaner that works for us. It is a heavy duty cleaner and does a great job. All I can say is the tile and grout are clean when we're done.

I've not used it to cover grout. My poor experiences listed in the review I submitted may or may not apply in your use case. I'd think of this is a coin toss situation. On the up side, due to that it's rough surface, it might actually stick to grout better than other surfaces. On the down side, you may not be able to properly clean the grout such that this stuff can stick. When I grouted my bathroom, I used a grout that was epoxy based. The clean up needed to be done immediately and was done by using water diluted white vinegar (acid). I'm not sure if this clean up method is advisable in your situation or not but it may be an option. No sealant was needed due to the epoxy and was inherently mold resistant. Alternately, if your concern is the mold on the grout, you might consider using a sealant since that's MUCH easier & quicker to do.

I wouldn't. there is a mixture that is sold at most tile stores specifically for that. it forms a water proof membrane behind tile.

No. It is incredibly porous. There is no amount of sealing that could change that. The texture of the tile makes it nearly impossible to clean. Also, the way the tile is situated on the mesh combined with the texture/varying depths of the tile makes it incredibly difficult to grout, which is problematic. I wouldn't recommend this tile in a food prep space because it can't be cleaned - it will harbor bacteria and other debris. If use this in a shower, you will probably end up with a mold issue or other water damage. This tile would be best suited as an accent tile on a mantle, backsplash for basement bar, etc. No. It is incredibly porous. There is no amount of sealing that could change that.

You could use it on a concrete shower floor and it would seal the floor. However this stuff pretty much disappears when it dries and would not give you a finished look. There are resin coatings which give a nice finish and also seal out moisture.

Hi Angel When you are working with a tile like you need to seal the stone/grout so it helps lock it up and make it more resistant to staining. With a good quality stone and grout sealer it will help deal with dirt and grease. The better the quality of the sealer the more resistant it will be to staining. Cheers Colin Wharton Rocky Point Tile
