Thinset removal between inserts(Thinset = TOUGHSTUFF)

Hi folks, I recently set a new tile floor down in the kitchen. I put in some inserts that are squares of pieces of stone betheen the tiles. The rookie I am I didnt clean out enough of the thinset between the stones and now dont have any depth to put the grout down. I tried using my dremell (sp) with a diamond bit but that thinset is some tough stuff and it wasnt long before all I had was a nub left. Any suggestions on how to grind/clean out excess thinset?.....Thanks.

Been there!

I used a glazed ceramic tile with 1/8" gap and ended up cutting a scrap of wood into a wedge and just scraping it through to remove it from in between. If the fat-end of the wedge is wide then it's ok to hold in your hand - rather than using a tool and risk gouging your tiles.
(believe it or not - scraping it off like this is more effective that going at it with a bit or solvent of some type - but a tad bit time consuming)

When the gap was too small for that I used a set of small-head screw drivers (flat-head) and tapped them through with a small hammer.

I promise - you'll never forget to keep your grout gaps clean in the future!

Good luck!


At this present moment in time I am making cabinets for the kitchen - just in case you wanted to know what I'm doing when I'm not around.

I use a straight bladed screw driver to scrape off any high spots of thinset. I usually do this the next morning before 24 hours is up. It is usually pretty easy to do at that point. The longer it sits, the harder it gets.
