View Full Version : Grout sealing: Did I screw up?

We had a LOT of tiling done last year (big kitchen, 3 bathrooms, hallways, entrance foyer), all with porcelain tile and light colored grout, and the tile guy didn't even MENTION sealing grout. Doh. So I finally went to the same store we bought the tile at, to get some grout sealer.

Since the tiles are all large and the grout lines are VERY narrow (1/8" or less), I also bought a bunch of small artists' brushes with which to apply the grout sealer. And a kneeling pad.

A week later, my back's broken, my arms are killing me, and my knees will probably never be the same, but it's all finally DONE. I had several unopened bottles of grout sealer left over, so I took them back to the tile store. Salesman said why don't I keep them, because the grout will have to be sealed again in another year and the stuff doesn't go bad. I said "What?? The sealer only lasts a year?" (*&&%%$#!!!

So I found out about this forum and browsed the posts about "grout sealer" earlier today. Now, too late for my back etc., I learn that the stuff the store sold me (water based silicone) indeed has to be redone every year. This is Not A Good Thing At All. I also read about Aqua Mix Sealers Choice 15 which lasts 15 yrs (now THAT is more like what I had in mind!!!!), so I went to Lowes this afternoon and bought some.

Reading the back of the bottle, I see it can be used on tile (which I don't need it for) and also grout (which I do). But in the instructions it says that the surface to which it'll be applied "must be free of previous sealers". But.. but... I just got done putting down the semi-useless water/silicone stuff (which soaked in and dried amazingly fast, btw). Does that mean I can't use the Aqua Mix on top of it? But how would I remove something that has already soaked into the grout? :-(

Or was that "must be free of" referring to TILE, not grout? (please Lord)

Also... when I tested the previous stuff on a section of white grout in a bathroom, it did yellow it a bit. So I didn't use it there. Will the Aqua Mix Sealers Choice do the same thing? I really don't want yellowy white grout. :-/ But I don't want dirty grout in there also, which is what we already have, after 8 months in the house. Not awful, but noticeable up close. I read here about Stone Armor Tile & Grout Restorer. Should I use that on the white grout, and then seal it with the Sealer's Choice? I'm assuming I can buy it online, as neither Lowes nor Home Depot nor the tile store carries it.

So, did I screw up royally by putting down the water/silicone sealer, to the extent that I now can't apply the AquaMix Sealers Choice? Not that I am looking forward to doing that job all over again (OUCH) but I don't want dirty grout either.

Thanks!

Hi Lainey,

Sorry for the delay. :)

I would try the Aquamix over the other sealer in an out-of-the-way spot just to make sure there is no adverse reaction. I would then go ahead and do the job. You can use a small piece of a sponge to apply the sealer and keep a damp rag handy to wipe off the edges of the tiles. It will go a lot faster than the artist's brush.

If you have enough Sealer's Choice to seal the shower, go ahead and use it. It's an excellent product. If you need more sealer, order Stone Armor from our store. It has a bit more viscosity than Sealer's Choice (more solids). It's an excellent product, also. :D

Hi Lainey :)

I, too, am very sorry for the delay.

You can seal over other sealers. Impregnators over impregnators.

It’s not a good idea in your case, though.

All silicone-based sealers will yellow over time, but yours did it immediately. If you seal over that junk, your joints will continue to yellow. White joints that have been sealed with silicone turn a dark yellow in less than a year.

A one-two punch of TYW Heavy Duty Cleaner & Stripper, followed by TYW Tile & Grout Restorer will remove the silicone. Then you can reseal with no worries.
