Thin Set directly on linoleum??

Question

Can tile adhesive, (thin set) be applied directly to linoleum, without using backer board? This is for a pretty small area, just going under a washer and dryer. Thanks.

Answer 1

If the vinyl is glued well to cement you can . Use thinset that says on the back that it ll adhere to vinyl.. If your over a wood subfloor take the vinyl up and start anew w/ a cement board .. If going over vinyl rough it up w/ sanding and allow several extra day for drying and grouting since the drying time is slowed when going over a non porous substrate. I don t care to do it this way but w/ proper technique it can be done and will hold  GL

Answer 2

the vibration of the washer and dryer will likly crack the grout

Answer 3

If the sub floor is level and free of any and all bumps or holes no matter how small,yes.

Answer 4

If the underlayment is solid. If the linoleum is not foam backed. If you confirm the original linoleum is still solidly glued. If you sand the linoleum with a coarse grade sand paper. Then yes. Even then it may fail. Why not just remove the linoleum?

Answer 5

never never, if the under floor fails, then your brand new floor fails.

especially under that type of area where the flooring is under unusual stress.
