    Can't get paper up from old vinyl floor. Laying ceramic tile on kitchen floor
    I looked for a similar question on this site before asking and all I could find is a question about ripping up vinyl flooring to lay hard wood flooring down... So I will ask my question, I just got done ripping up the vinyl from my kitchen floor and plan to lay ceramic tile down tomorrow, I too have the same problem as the person wanting to lay the hard floor. I can't get all that paper that is glued to the plywood up. Do I really have to get all that up, I'm thinking I shouldn't have to since I will be laying down cement board before I tile. I read NOT to sand the paper off, and I checked into the adhesive remover, that can work, but it seems to be very expensive. Thanks for you're answers

    So you plan to install Wonderboard as a subfloor before tiling, right? You can forget the paper, screw and glue the wonderboard down using a modified thinset mortar, same for your tiles.

    Hi Garcia,

    I definitely agree there is no need to remove all the backing, just hope it is flat. If the flooring is real old, the backing might contain asbestos, so if it is, do not scrape or sand. Definitely no chemicals.

    However... when vinyl is installed on a plywood subfloor, the flooring company almost always also installs a 1/4" underlayment. If this is the case, you need to also remove it. NO 1/4" ply should be in a tile installation. You need to get down to the subfloor.

    Be sure to re-fasten the subfloor, then install your favorite CBU with thinset per directions. Don't forget the mesh tape etc. Did you consult a span chart to make sure your joists are stiff enough for tile? How thick and how many layer of subfloor sheets do you have? How does the floor feel? What type and size tiles are you going to install?

    Yeah there seems to be 2 layers of plywood, so your saying I should remove the top layer with all the paper and glue still on it?

    I did not consult a span chart, where would I do that?

    As far as the subfloor, it seems that the two are probably 1/2" each, not sure though. The floor feels good, our neighbors tiled their floor not too long ago and our houses are practically the same. So I don't have any fears about putting tile on the floor.

    We have 12x12 ceramic tile with a 1/4" hardiboard underneath. We were going to install it today, but my helper ran into some issues and we now have to wait until tomorrow.

    Are you saying the subfloor system is 2 layers, and then you have some 1/4" on top of that to which the vinyl was glued to? Is the top sheet 1/4" or what? How old is the house? Where is it?

    Probably 1/2" thick is not a good enough answer.

    I can check my span chart if you'll provide the numbers I mentioned before. It is free today!:D
