After years of dealing with three different types of flooring in my doctor's office, kitchen, and pantry/hallway, we've had enough. The kitchen had 16-inch ceramic tile, and in 13 years we've probably broken enough glassware for replacement cost to cover the new luxury vinyl floor that will replace it. The DR had a VCT tile, but the gaps were getting bigger, which was a problem. The lobby/pantry had terracotta tile that was never properly sealed so it had permanent stains. This meant removing a lot of tile, glue and grout to make all three sections of the floor wood so we could all level them with underlay as all three were slightly different heights... and trip hazards. The demolition tools used were an SDS Plus chisel, a Thinset demolition tool, an angle grinder blade and a hammer to install the new flooring. It was a dusty and noisy process that I didn't want to start because our new vinyl floor was made from 16" x 32" sheets and was 1/4" thick because the underlay was already installed so I could just lay it down. existing garbage. This causes problems when raising the floor (e.g. reducing the height of the shelves); requiring door material to be removed from underside; lifting electric baseboard heaters; and still have that solid tile under you instead of a sheet of wrought iron plywood... plus extra weight on an already heavy floor. The tool that really worked the best for me on the mortar base was the 24-inch Dasco Pro 640 Shingle Ripper, which allowed me to slip it under the loose base and lift it up in big chunks, but no matter what or how I did it did. There was a mess and the store's vacuum cleaner was given a good workout. This nozzle did a great job removing the base from the mortar, but it had fiberglass mesh in it so I had to bend it back and then cut it with a razor to get the big leaf out. The smaller the angle of the drill bit to what I was using, the better it worked. As for the scale, it pretty much pulverized the base of the solution and created a lot of dust. Bosch - HS1465P performed better but was narrow requiring more passes. I should have covered more items, but a lot of surface cleaning is required now.
