Schluter Systems Self-Adhesive Peel and Stick Ditra Heat Membrane 8.4 Sq Ft (0.78 Sq M) Sheet DHPS5MA Features Mortar-Free Waterproofing Underlayment, Floor Warming, Uncoupling Mat

I needed a membrane over a cement slab and wanted a heated floor. This peel and stick version makes it a breeze. Just make sure everything lines up first and then stick it down. Easy to cut with a razor blade or table saw. You have a couple attempts to peel it up and realign if necessary.

These went down pretty easily. Way easier than having to use mortar underneath. Highly recommend.

Good product but not 8.4 sq. ft. Dimensions are 38.5 inch by 29 inch. Which is 7.75 sq. ft. Not the 8.4 sq. ft. listed in the description. Order according.

Awaiting installation of new shower system. Contractor says this is a new system to alleviate cold floors using tile flooring.

It beats installation with thin-set, it's a tidy time-saver when you are installing on a flat plywood substrate, easy to lay down and re-position if necessary.
