Prodeso Membrane Sheet 10.8 Sq. Ft. (3′ 3.4″ x 3′ 3.4″)

Waterproofing for the room is in the layer above the floor heating system. The layers for waterproofing this type of floor are:

• subfloor
• thinset
• uncoupling membrane
• tempzone heating cable
• waterproofing tape for seams and corners
• thinset or self leveling cement
• tile floor

WarmlyYours has recently begun including floor sensors with our heating elements to help ensure customers will have everything they need for optimal operation of their radiant heating systems.

The sensor included with your floor heating element can be installed with the heating system (the sensor is equally spaced between runs of the heating wire--see your install manual for more info). Installing this sensor with your floor heating control will enable energy efficient operation of the floor warming system based on the floor temperature instead of the ambient room temperature.

We generally recommend that you install a second, unconnected backup floor sensor alongside the primary one. In the very unlikely event that your first floor sensor is damaged, this install method will save you from having to pry up flooring to replace a floor sensor. You simply disconnect the damaged sensor from the thermostat and connect the backup sensor.

In addition to the floor sensor that was included with your heating element, our nSpiration Series thermostats also come with a floor sensor. If you purchase both a heating element and an nSpiration Series thermostat from WarmlyYours, you'll have a primary and a backup floor sensor for your system.

Self-Leveling (SLC) Cement is not recommended for use over Prodeso. Contact WarmlyYours if self-leveling underlayment is required.

Install membrane over entire floor first, then heating cable, then do the tiles 1 or 2 at a time. Never cover the Prodeso entirely with thin-set first. Only apply as much thin-set as needed to lay a couple of tiles at a time.

Waterproofing is recommended under and around tubs/showers. It’s also recommended wherever the tile could possibly be exposed to considerable amounts of water. Prodeso is naturally waterproof, but the corners and seams need to be treated with waterproofing tape and thin-set. (Use Pro WP Waterproofing Band 5“ - Soft polyethylene tape – to seal seams.)

A decoupling membrane protects the installation from differential expansion/contraction between the substrate and the flooring, relieving almost all shear stresses. Crack isolation protects the installation by isolating the flooring from minor in-plane substrate cracking.

Yes, the sensor wires may be trimmed.  Most local code requirements call for 6“-7“ of extra wire from the gang box.

Prodeso installation membrane does not eliminate the need for expansion joints (adhere to local codes).

Unroll the membrane the day before installation to flatten it and avoid any potential ‘memory’ due to environmental conditions.
