Product Description
Weatherdek PVC Membranes are specifically designed for use as
waterproof walking surfaces on Roof Decks, Decks, Balconies, Patios,
Walkways, Ramps, or where ever an attractive and durable traffic bearing
waterproof surface is required.
Weatherdek membranes consist of printed polyvinyl chloride (PVC) films
laminated to a polyester backing. The finished materials are 45 or 65 mil
nominal thickness and supplied in 72” or 54” wide rolls. An embossed
finish on the traffic surface of the membrane provides suitable footing for
pedestrian areas and access routes.

Surface Preparation
Weatherdek membranes can be applied to either plywood or concrete provided the
surface is relatively smooth and consistent. To achieve the proper surface some
preparation may be required.
•
•
•
•
•
•
•
•
•
•
Plywood Substrates:
Minimum 3/4” Tongue & Groove, CD grade or better plywood.
5/8” plywood acceptable with proper joist spacing.
Pressure treated plywood must NOT be used.
Maximum 20% moisture content.
Install plywood with the face grain perpendicular to joist direction.
Screw plywood to supports with corrosion resistant screws.
Countersink all screw heads.
Use appropriate adhesive between plywood and supports.
Sand all plywood sheet joints to ensure no height differences.
Fill all sheet joints or imperfections with a recommended cement based patching
compound.
•
•
•
•
Concrete Substrates:
Concrete slabs must be sound and clean.
Maximum 75% relative humidity when measured with hygrometer.
Grind all imperfections to ensure smooth finished surface.
Fill all cracks or imperfections with a recommended cement based patching
compound.
During surface preparation special attention should be paid to detail areas such as
inside and outside edges, or corners. Ensure these areas prepared in order to create
a consistent 90° turn for membrane at walls, upstands and down turns over outside
edges.
Ensure all required flashings, under flashings, drain bodies or scuppers are properly
fitted prior to laying the membrane.
Inspect and clean the entire surface of all dust and debris. In addition to sweeping
a dust blower or vacuum may also be used to remove dust and debris.
Note:
All surfaces must have a minimum slope to drain of 1:48, and should not be subject to
standing water at any point.
Ensure proper slope is maintained after settling and shrinkage of building structure.
2
Revised: March 2010
Membrane Layout
Plan the membrane layout to minimize the amount of seems required, and when feasible
orient joints perpendicular to the slope of the surface, with seam overlaps parallel to the
direction of slope.
Begin the layout at the outside edge of the surface, furthest from the building, and snap
a chalk line to align the first sheet. Roll out the first pass and rough cut the material to
length, leaving approx 4” overhang for outside edges, and a minimum of 6” to turn up
and walls or upstands, and ¾” for seam overlaps.
Check all materials and be sure there is enough product to complete the required
installation. Verify all materials on site to be the same LOT or PON number.
Membrane Installation
Align the first pass with the chalk line, and be sure it is lying smooth and flat with no
tension in the sheet. Fold the material in half, back from the chalk line over the
remainder of the sheet. With half the back of the membrane exposed begin applying
adhesive.
Use a paint roller on an extension handle to apply an even coat of Contact
Adhesive to both the back side of the membrane and the exposed deck surface.
Leave all seam overlap areas free of adhesive, a ¾” wide strip of masking tape can
be used to ‘mask’ these areas while gluing. Contact cement may be used in
temperatures as low as 0° C.
Allow the adhesive to dry until it is ‘tacky’ to the touch, and then carefully roll the
glued membrane back onto the glued substrate working from the center of the
sheet in a ‘V’ shape out to each end. Take care not to stretch the material, and
avoid wrinkles or air pockets. Use a plastic spreader or roller to smooth the
membrane onto the surface.
Repeat these steps for the remaining half of the pass, and subsequent passes to
completely adhere all required membrane.
Once all horizontal surfaces have been adhered, use a paint brush to apply adhesive
to wall, upstand and outside edge areas and adhere membrane in these locations
taking care not to stretch the material into corners or over edges.
With all membrane fully adhered, begin the seam welding and detail areas.
3
Revised: March 2010
Heat Welding / Seaming
When all passes are adhered begin to heat weld
the seams. Seam overlaps should be 20mm
wide. It is important for aesthetics to have a
straight seam line, trim the material to a straight
edge if necessary. The overlap area should be
completely free of any adhesives or other
contaminants that may contaminate the weld.
Using an electric heat welder with a ¾” slotted
tip, position the tip between the two layers of
vinyl applying heat to both layers. Make the
first pass by slowly moving the tip along the
seam while applying pressure to the heated
layers with a neoprene rubber roller. Weld approx 18” to 24” with this pass and
then make a second pass over the weld to bevel the edge of the join.
For the second pass hold the tip of the welder parallel to the seam, directing the
heat onto both the lower surface and the edge of the upper layer. Once the upper
layer shows signs of melting roll over it with the roller at an angle to bevel the edge
and melt it to the lower layer of vinyl.
It is important to check the weld every so often by pulling on it once it’s cooled.
Weld all overlapped seams, and use the same process for welding detail areas such
as folded corners, over flashings and tabs.
Detail Areas
Inside Walls & Edges
Turn membrane up the inside wall a minimum
of 6”. The building wrap and siding should
overlap the membrane.
Note: Weatherdek does not recommend the
use of a ‘fillet’ or ‘cant strip’ at inside edges.
4
Revised: March 2010
Inside Wall Corner
When there is a 90° inside corner created by
two walls, there is no need to cut the
membrane. Simply fold the material (dog
ear), to the inside and weld it closed. With
no cuts this detail eliminates the possibility
of leaks through improperly sealed corners.
Outside Wall Corner
When gluing the membrane in place,
adhere it tight to the deck surface and
locate the point where the membrane will
meet the corner of the wall. Make a 45° cut
from this point back towards the wall and
fit the membrane around the corner. Cut
an over flashing made of Weatherdek
membrane that will overlap the existing
membrane by 1”. Glue this piece in place
and heat weld the overlaps.
Outside Edge Corner
For an outside edge corner, turn the
membrane over the edge of the deck surface
on either side of the corner and fold the
excess membrane back to one side and heat
weld in place. No cutting of the membrane
ensures a watertight detail.
5
Revised: March 2010
Outside Edge Finish
Adhere the membrane over the edge of deck
surface a minimum of 2”, and mechanically
fasten using the Weatherdek Aluminum LTrim.
Use Butyl tape or an approved polyurethane
sealant behind the L-Trim to seal all fastener
penetrations.
Additional Detailing
In addition to the standard details shown above please refer to the following details
as required by site and design conditions:
RoofDrains
Use approved Roof Deck drains designed
for use with membrane materials when a
drain outlet is required through the
Weatherdek membrane.
Position the drain at the lowest point of
the surface. Install the body of the drain
with proper substrate rebate prior to
membrane installation.
Membrane is
sealed into drain body using an approved
polyurethane sealant and fastened by the
drains clamp ring.
6
Revised: March 2010
Masonry Inside Edge
For masonry or brick veneer inside edges
run the membrane up the required number
of blocks to achieve the proper upstand.
Make a saw cut into the mortar joint and
insert a galvanized counter flashing. Both
the membrane and flashing should be
sealed in place with an approved
polyurethane sealant. The flashing should
extend down over the membrane a
minimum of 50mm.
Posts or Penetrations
For
penetrations
through
a
Weatherdek Surface, cut and fit a
boot around the penetration that will
fit tight to the penetration, and
extend over the membrane on the
horizontal surface. The boot should
extend up the penetration enough to
be flashed over with another piece of
Weatherdek membrane a minimum
of 100mm high that is adhered to the
penetration and heat welded to the
boot at the base. The top of this
over-flashing should be protected
with a cap flashing.
