Hello, I am redoing my kitchen and the floor slopes downward from one side to the other. It is out by about an inch in height from from 10 feet across. Would self-levelling cement fix the prob? Also, can you lay tile over existing ceramic tile or should it be removed. regards, Steve
It would be best to find out why it is uneven. Leveling compound will not work.
What kind of construction do you have? is it on a slap or do you have a basement or crawlspace under it. How old is the home, how long has this been a problem? What kind of soil conditions in the area? What kind of foundation do you have? Are there cracks in the walls or ceiling?
We remodeled a garage into a casita. The floor slopes, but no one really notices. The recliner swivels around on its base by itself, and the fishbowl is minutely out of level. The fridge, cabinets and countertops are level. Other than that, it's not worth the hassle for the stuff that sits on the floor. Besides, IMNSHO, it is impossible to lay concrete that thin to put a topcoat on there and taper it from one inch to zero without having the concrete sluff off at some future time. Maybe tiling over it would make it work, but it would be an expensive experiment.
As for removing the tile, yes, yes, yes. You will get arguments about tiling over old tile and roofing over old roofing. You believe one way or the other. I like to strip it down to the base and start from hard rock. I did go buy a $20 HD air chisel when doing mine, and it whisked right through tile, and a couple of layers of flooring and the adhesives, too. A noisy, messy job, but we covered it with travertine, so wanted a good floor.
Do it once. Do it right. (my motto) Nothing I hate more than finishing a job, and regretting taking a little more time on it, or skimping on something that made a difference in the end results.
With a basement there, I would consider two things.
has the settling stopped. I would hope it has on a 57 year old home, but ???
Can it be corrected by careful jacking and proper support. For this suggest you consider getting the in person advice of a structural engineer. You don't want to create more problems.
