Grouting Over Grout?

c5150b

Can you do this. I had to replace a tile and can't find the old premix that I used. I think it was discountinued. Also I've added some border strips and want all grout to match. Plus I did a crappy job grouting when I first did the tile job. I have never sealed it. Can I just grout over the grout or is there a bonding agent that will allow this to happen? Thanks all for any help!

use a grout chart to match the new grout close to what you have.
Mix it up and slap it down.
Wait a few days for it to fully cure.
How does it look?

If it doesn't match, then use a colorant that "stains" all the grout to the same color. Aquamix makes an extensive, quality product.

Thanks for the info...That's probably what I'll have to do.

You did a lousy job because you used Pre-mixed grout and you don't seal that crap if that is what you used, is that what you used? as that's what you stated above.

Pre-mixed is garbage and shouldn't ever be used.

ACTUALLY I did a lousy job as it was my first tile job and lets just say there were beers involved ....I have used this grout many other times throughout the house with no problems. Anyway I found the manufacture so I can order direct. Thanks for the input however

And what grout would that be, have a name and brand?

don't understand how it's your FIRST tile job

but you've used the grout on OTHER jobs.

what did you grout? bricks?

I'd assume that when he originally grouted it was his first tile job and he's used it on other jobs since then.

I've decided to use my fein multimaster tool to cut the lines and redo.

Friendly tip:

Don't EVER use that kind of grout ever again!

Live and learn! Plus premix is much more expensive..

That stuff is GARBAGE.

I used that premixed crap about 6 months ago only because the HO had some and it was for a small tile job in a closet. It looked OK for 24 hrs. Next day I ripped it out, used good stuff, and told the HO.... "I told you so!"
