Tile Underlayment Membrane

Video, Flooring Published 07/23/2008 by Danny Lipford



Schluter-Ditra Tile Underlayment is a polyethylene membrane that replaces ½” cement backer board when applying tile over a plywood subfloor. At only 1/8″ thick, it can significantly reduce the finished height of a tile floor. The flexible membrane comes in rolls and weighs only two ounces per square foot. After being cut to length, it’s set in a bed of thin-set mortar then covered by another coat of thin-set in which the tiles are laid. The membrane acts as an uncoupling layer to prevent cracking as well as providing waterproofing in one easy application. It’s available at The Home Depot stores.

    Hi:

    I want to replace some linoleum with tile in my kitchen and bathroom. The sub floor is cement (Condo built in the 80’s). Will this stuff work on a cement sub floor?
