My question is mostly a scenario: I have a friend who is the facilities manager at a large bio-medical company that is looking to redo their cafeteria floor. The majority of the facility is granite tile, but for some reason, they installed what looks like mastic glued 2' x 2' linoleum squares in the dining area. Due to the constant mopping of this floor, these tiles are starting to come loose on the edges. It appears that they've started to TAPE these down on the seems. I am in dire need of work for my company. This is a GIANT floor, the largest I've ever contemplated doing: 2556 sq. feet. Here are the issues with the project:
1. Getting the old tiles up: is there a machine that will scrape up the tiles? I removed residential sticky tiles from a basement floor we were converting into bathroom space, and it took ALL DAY scraping to get just a 10' x 8' section up....can't imagine doing several thousand feet without a special machine....do they make a commerical scraping maching?
2. How to get the old mastic off the concrete after tile is removed? I've noticed there is a non toxic solvent called Citrus KIng that appears to remove a wide range of glue....will this work?
3. Another issue: the walkway that borders the cafeteria floor is divided by a metal strip, BUT it appears that the concrete that is covered by the "sticky tile" isn't as deep as the granite tile side; this would prevent installing tile unless the concrete is grinded down to give space for the thickness of the tile.
4. My friend told me they've budgeted $25,000 to $30,000 for the job, but GRANITE tile to match is at least $5-$10/sq. ft. just for the tile.
SO, I was thinking to install a self-leveling concrete overlay system. Does that seem like the smartest material to install?
I need this job desperately, and I'm hoping that it will lead to more commercial work, but my experience isn't in commercial work, but residential. I have the inside track to get the job, but I don't want to let my friend down, or lose money. The unknowns for me are:
Getting the old tile up, limitations on the concrete product, and how efficiently the new surface can be installed. Any thoughts on this project are greatly appreciated.....
I am sincerely desperate for this work but am afraid of the unknowns....
