I am installing a new bathroom floor. I plan on getting an electric underfloor heating mat, 2 backer boards for under the heating, screed the mat and tile over this.
My question is can I place the back boards on the cork vinyl(even though it's got glue on top) or do I need to remove the cork.
Another option is cleaning the glue off the cork and using the cork as the subfloor. Is this possible?
Thanks for the help, first timer here.
