The tile still broke up in pieces with the grout lines cut but the pieces were much larger making the job faster. Going perpendicular to the ridges is much more effective. Altogether the job took about 4 hours and left the new surface pretty smooth. I may just hit any high spots with the grinder again to make sure.

It's a little late to do it once you start laying tile. So now the thinset, I found a rental tool at homedepot. Its a floor buffer and you put this round buffer with teeth and it removes thinset. DUST but fast. Been doing tile for 10 years and so far best bang for your buck. It will soften most thinsets up a bit but the biggest gain is in dust mitigation. Let it soak as long as you can, I try to let it set for at least an hour.

There will still be dust but it will be manageable when wet. I just scaled square feet today and although it was a back breaker it wasn't nearly as bad as it could've been. Used a Bosch rotary hammer with a 1. Couldn't find a wider bit but this actually worked well. I use a 4" manual scrapper to ensure everything is flush and this really cleans any remaining thinset. Good luck, it isn't for the faint of heart!!! Sign up to join this community.

So far I have had two days with a cold chisle, screwdriver and hammer in my removal attempt in bathroom one and still have some to left on the floor. You can use a power chisel, air hammer, or demo hammer. BMitch - Thanks for the suggestion. Could you put that as an answer so I may consider accepting it along with other potentential solutions. By the way that scraper that fits in your sawzall is trash.

Always, always, always wear a dust mask when grinding, sanding or cutting thinset or concrete. The dust can eventually cause silicosis which can be deadly!!! Add a comment. This is a good idea if you live in a cold city like Saint Paul , Minnesota, as it will lower your heating costs. Before you begin installing your tile floor, make sure the subfloor is completely flat and smooth.

When you walk on a tile installed over a hole or bump, your weight won't be evenly distributed and the brittle tile will crack. Therefore, smooth down any raised areas and fill any gaps you find. Another problem you might find in the subfloor is nail heads. They can stick up and cause problems; so verify that they are all level with the subfloor. With a concrete subfloor, make sure there are no cracks or gaps. While some small, hairline cracks can be ignored and gaps can be filled, they may be a sign of a greater, underlying weakness.
