I am doing some work in an old appartment complex turned condo unit.The bathroom floor had the original mozaic ceramic tile.There were some loose tile around the raiator so after I removed the radiator, I then removed the loose tile and loose mortar in that area.The area of loose tile was about 8″x6″.I found the loose mortar to be about 2 1/2″ deep with more solid concrete below that.I also noticed that part of the floor was warm so I’m assuming that the pipe that feeds the radiator also runs through this mortar.
Is anyone familiar with this type of tile installation that was done years ago and how I might handle this? Can I patch the loose area with some sort of vynal cement product or floor leveler and then put down the new ceramic tile over the old?
I appreciate any help.
It is imperative for someone at the end of an HVAC installation to commission the job to ensure the efficiency of the system.
