Make sure the concrete floor
is even, fully cured and free of
debris, oil or waxes. The wedi
Building Panels are installed
using modified thinset mortar
using a 1/4“ × 1/4“ (6.4 × 6.4
mm) notch trowel.
Stagger all joints when laying
wedi Building Panels on the
floor. Apply some weight on
the boards during initial thin-
set setting time and especially
over board transitions.

wedi Joint Sealant can be applied with a continuous 1/4“ (6.4 mm) bead
while setting the panels in position (seams butted tightly) or after they
are set and with the bead of sealant installed over the seam before it is
spread flat using a putty knife. All excess sealant must be spread flat so
joint sealant covers the seams at least 1/2“ (12.7 mm) to 3/4“ (19 mm)
on either side of the seam. In dry areas, wedi selfadhesive alkali resistant
mesh tape can be used to reinforce the seams.
Install electric floor warming system according to manufacturer‘s recom-
mendations. Please make sure the wedi Building Panels are not punc-
tured by staples or other mounting devices.
Installation of Electric Floor Warming
Systems using conventional wedi
Building Panels
The wedi Building Panels save time and money while conserving energy
when used in conjunction with any common electric floor heating sys-
tem. The extruded polystyrene foam core construction makes the system
100% waterproof and the perfect heat insulator and thermal barrier.
wedi Building Panels are equipped with a cement resin surface that is
reinforced with a fiberglass mesh and provides an ideal bond to any
common tile adhesive or self-leveling product which may be needed to
integrate an electric cable or mat system.
Note on electric floor warming systems
Electric floor heating systems can be installed as per manufacturer’s in-
structions onto already installed wedi product system or underlayment
surfaces and reinforced elements (e.g. wedi Building Panels, Fundo floor
elements, Sanoasa benches, Sanoasa loungers). Here only products ap-
proved for such individual application and areas such as i.e. wet rooms
should be used.
Electric under floor heating systems are easy to mount on the wedi
Building Panel and downward heat loss is prevented, making the heat-
ing system noticeably more effective.
