ProMelt Submittal

Sizes: 2' and 3' Wide Mats
ProMelt Mat is a complete heating mat consisting of a series resistance
heating cable and a single power lead for easy single-point connection.
The heating cable is pre-formed into a mat to provide consistent spacing
and quick roll-out installation on the jobsite. The heating mat length
cannot be cut to fit.

Installation Parameters
Determine a time to install the mat when equipment, heavy tools, and site
traffic will be minimal. Apply the surfacing courses over the mat the same
day the mat is installed.
If installing mat in the upper layer of a two-stage concrete slab or the
upper layer of an asphalt application, the mat should be completely ready
for the second stage. There is limited time between stages, as the slab
should not be allowed to fully cure or the asphalt to completely cool.
Therefore, lay out the mat and tie it to rewire that can be quickly lifted into
place after the first stage is laid.
If a slab sensor is installed in this second layer, plan ahead so this does
not cause the first layer to cure or cool too much.
Inspect the area and remove any sharp objects.
Install in temperatures at least 40°F (4.5°C).

WARNINGS PROVIDED WITH THE PRODUCT.
