Step 3 -
Suboor Preparation
• Ensure the subfloor is dry
and smooth. If necessary an
appropriate smoothing or
levelling compound should be
applied.
• If required, prime wood or
sand and cement screeded
subfloors. For proprietary
subfloors refer to the
manufacturers instructions.
• Install perimeter expansion
strips within the DCM-PRO
system, along any perimeter
or sectional expansion joints
within the subfloor to preserve
their function. Remove the
tape from the perimeter strip
to expose the adhesive back
and begin pressing it into the
wall, ensuring the strip also
touches the floor.
Installing the perimeter
strip allows for dierential
movement between the
finished floor level and walls.
IMPORTANT: When installing DCM-PRO Peel and Stick membrane
the surface the membrane is being applied to must be primed and
smooth, such that a clean and continuous bond can be made.
If necessary an appropriate /" levelling compound should be
applied. Coarse and/or loose subfloor surfaces will prevent the
membrane from forming a continuous bond. For example; cement
coated insulation boards with a raised pattern must have a levelling
compound applied over.
• Recommended Step - Install
Warmup® insulation boards
over the subfloor referring to
their installation instructions.
Warmup insulation boards
are made of extruded
polystyrene, faced on both
sides with a fibreglass mesh
embedded into a thin cement
polymer mortar. They will
help reduce the heat up times
of your system for optimal
performance.
