Way too much water in the mix!!!!!!!

Have it properly regrouted!

Hi Floorguy,
Thanks for your response, but...my husband measured the grout/water mixture himself and made it exactly what the tech support guy at Custom Building Products said was correct ratio for their product (1 part water to 3 parts grout). Also, it was mixed to the proper (peanut butter) consistency the company rep specified so there was definitely not too much water in the mix the second time.

In fact, the tile guy complained it had too little water--obviously, it made it harder for him to work with instead of the slop he had used before.

Any other ideas?
Thanks,
debbe

I'm not getting it???

Try another brand of grout.

Sounds like you either did not let the grout "slake" after you mixed it, or you did not force it in with the float. Also, you might have "cleaned" with a damp sponge too much right after you grouted, which could have added too much water.

Try John Bridge tile forums and do a search through the threads.

Oops, I missed your "high desert, very dry" climate clue.

Did you spray-mist the floor a couple times afterward? If it dried out too quickly, that might have been a problem.

Also, if the bare joints were completely dry, might have helped to wet them a couple hours before you grouted. That might have minimized the amount of water that would get pulled out of the setting grout.

Actually, whether you're supposed to do it or not, a penetrating sealer called "Pourous Plus 511 by Miracle Sealants" could help in a situation like that. I have seen that actually seal it and stop the grout from coming up in the same type high desert situation where before that, every time the grout was wet, it was dissolving in the water and coming up. Another good water based sealer was tried before and it didn't do anything to help that particular situation but perhaps because the Porous Plus contains petroleum products, it was able to go in and really set and seal everything well with no problems and without having to regrout. This is well past the original post date but I hope this helps someone else out there.

Also a product that helps to seal the grout a lot easier is a product called the "Grout Wand". You can actually apply the sealer while standing and it holds a lot more sealer than a small application bottle. The sealer only comes out when you apply pressure and it has a wheel applicator that you roll as you walk as well, so it makes it easier.
