- DIY Subfloor smoothing and "Resurfacing" after tile removal!
Today in THE HOUSE we're removing the leftover thin set and glue left behind from removing our travertine tile.
This video is the second in a new series I'm posting, documenting the rebuild process of our house following a flood that occurred when a plastic fitting failed on our bidet. Water got into almost every room of the house after flowing for almost 5 hours.
We rented a floor polisher with a Dimond blade coating removal too. We made some splash guards, taped em' to the walls, and got to work! It's important to keep the surface you're working on wet, we had water being sprayed while grinding it all down. Doing the work in small sections, we vacuumed up the concrete/glue slurry as we went.
This got up everything that was left over by the tile removal. Now we have to patch the spots we went too deep on while removing the tile!

Great video, very informative.
Just a few helpful hints for anyone going through this... First, a rotary hammer is sufficient for most home projects. Don't let the rental companies talk you into any big pieces of equipment or hammers. Inexperienced users will do hella damage to their concrete slab. When taking up the tile, you want to try and remove the piece whole. This will save you a mountain of cleanup work. Broken tile is very heavy and sharp and garbage bags and contractor bags are not strong enough to deal with the mess. If you keep the tiles intact, they can easily be stacked out of the way. The key to removing tiles whole is to use your ears. Tile with good separation from the thin set will sound completely different than tile still bonded to the thin set when the roto hammer is working. It also helps helps to simultaneously use a shop vac with a minimum 100 CFM rating to capture the insane amount of dust the roto hammer kicks up. Just lay the hose right there on the tile you're working on. Do NOT try and remove the tile and the thin set at once, instead focus on separating the tile from the thin set. This will save your concrete slab some damage.... Once all tile has been removed, you can then begin to focus on the thin set removal. Don't rent the machine shown in the video. It's bulky, hard to handle and is unforgiving in tight spaces. Also, don't hose your floors down because you are working with equipment that most likely has an extension cord. Use a mop and a bucket of water to dampen the area you are working in. For best results, use the roto hammer in short bursts to chip up the thin set. If an area doesn't chip up easily, skip it. The hammer will gouge your slab. For the tough areas you want to use an angle grinder with a thin set removal grinding wheel and a guard with a hose attachment to simultaneously remove the dust. Good Luck!!
Did you apply a floor leveling compound afterward?
I did, filled in the divots left by the chipping hammers and smoothed some uneven surfaces. The worst part was cleaning up the edges of the leveling pours and the drips. I used a grinder with a surfacing diamond blade, the amount of dust made it look like my house was on fire. I made pressurized "clean" rooms to isolate the dust areas.
Mistake number 1 using water
Why's that?
