Grout Over Grout


So, I am working on a shower with tumbled travertine 8"x8" and the grout lines are 1/4", wavy and it will be extremely hard to remove all the grout in this 5X3X8 shower. the grout in the corners are cracked, and there is a few spots in the middle of the tile that also has cracks.. I'm concerned as to what is causing the cracks in the middle of a wall, and I am not going to warranty anything. I'm going to remove the grout what is cracked, and strip the rest. This is probably a cheap polyblend sanded grout and I plan to use a good laticrete over the old grout and in the newly removed areas. Do you think after striping that the new grout will bond to the old grout? Or is this just a tear out? I dont want to try and scrape all this grout out because there is just too much labor involved IMO. thoughts? Thanks!

Re: Grout Over Grout


I'm not sure what you mean when you say you will strip the rest. Not sure what product you would be using for that.

But anything short of cutting out the old grout and getting new grout install a proper specs is a waste of time and your clients money. You can't "skim" grout over old grout with any success.

I agree with you that I wouldn't want to cut it out. I'd personally want to sub that to an outfit that does it. Let them have all the fun.

https://groutinfo.com/product/comlet...loor-care-kit/ This is what I plan to use to clean/strip and scrub the grout.. I was thinking to skim over to fill any holes or gaps, because its the tumbled travertine which has lots of missed holes and the original grout job was splotchy. I mainly am looking to fill all those holes, etc.. and then seal, and caulk so no more moisture can penetrate the tile/grout

Re: Grout Over Grout


What if you have mold behind the travertine? The grout may be failing because the travertine wasnít/hasnít been sealed so water has infiltrated the stone.

Great idea Tom!

Nothing to it. Much more controllable than a hand grout saw.

What do you consider not smooth surfaces? If it doesn't seal, it won't hold.

You'd have to try them surface to surface. Mounting tape if the Gecko's don't work.
