I just learned something! I didn't know Mapei had jumped on that bandwagon.
Here's your answer:
http://www.mapei.it/Referenze/Multim...out_TDS_EA.pdf

This is the first I have seen or heard of that product.

I might add that during my search I ran into many negative comments about the performance of that product.

Should I seal my shower tile grout?


I can assure you that this grout is absolutely crap...it dries rock hard in like 2 minutes and is so hard to remove the haze. I dont recommend it be used on polished marble. It also doesn't go on very well after using a sponge. i had to grout twice and it's not like I haven't grouted before. I have grouted about 5 times and never have had to do it twice.

Anyway there is nothing I can do about it now.

what i want to know is what type of grout should i be using for this application.

Thanks.

Boy! those are narrow specifications for application and use..."intermittent wet areas"...huh? I see you have to moisten the surface you are about to grout first before grouting. So, tell us Limit54, did you do that?

I wonder if there is any cement in there at all...it sounds almost epoxy-like, in taking so long to cure before traffic etc. I really wonder if this isn't a real DIY product that most people who tile for a living wouldn't even touch.

Well, that may be why you had less-than-optimal performance from your grout. Some stones and tiles are quite absorbent of different fluids and the reason some tilers like to seal their tiles on the sides before grouting - just to prevent any migration of, say, water, that would otherwise be there to manage the controlled hardening rate of the grout.

Just like cement: it has to dry at a controlled rate - not too fast , not too slow. Main reason you see newly-poured concrete covered up during the summer months...

I am not familiar with this product (although I know Mapei) but I am only suggesting that too little water might be the cause for the quick hardening and therefore the haze you might have had.

you know what you are probably right. The thing is that I've never had to go to the manufacturers web site and read the PDF...but I guess I should from now on. usually this stuff is printed on the packaging or it comes with a leaflet.

My purpose of buying this stuff, as I was skeptical was that it was made by Mapie and I trust them in terms of product.

anyway, all in all it worked and its just taking a little more work to get right. My tile is not damaged and that the main thing.

I like the tip about sealing the sides of the tile...Something I would never have thought about.

Once again i love this place.

Yeah, me too.

Sealing natural stone tile edges is one area I have no reservations about doing. It seems simple enough and a lot more sensible than some applications of sealers. In these days of cheap stones and multi-coloured grouts and grout colour-sealing, it is an insurance policy againt failures due to discolouration - and IMO any means you can find to reduce the risk associated with putting down a stone floor, the better...
