8.5.5 INSTALLATION 8.5.5.1 PLYWOOD

Substrates must be dry when membranes are applied. The plywood and the timber substructure shall have maximum moisture content of 20% when a membrane is adhered.

Plywood substrates shall be fixed according to the following requirements:

(a) Panels shall be laid with staggered joints (brick bond).

(b) The edge of sheets shall be supported with dwangs or framing, unless a structurally tested tongue-in-groove edge provides equivalent support.

(c) The maximum span shall be 400 mm.

(d) Plywood shall be laid with the face grain at right angles to the supports,

(e) A 20 to 30 mm triangular fillet shall be used at the base of any 90° up-stand.

(f) External edges shall be
chamfered with a minimum radius of 5 mm, and:

(g) Plywood shall be fixed:
Comments by The Rubber Roofing Co

Excess moisture will result in adhesion problems and “bubbling”

(a)  Strengthens substrate by offsetting weak points.
(b)  e.g. CCA 17mm Eco ply Ply floor H3.2
(c)  Refer ply manufacturers span tables for alternative
solutions (Spans) using thicker plywood or purpose made plywood flooring products.

(d) This is very important. Plywood strength is severely reduced if installed with face grain parallel to supports.
Do not accept substrate if plywood us installed incorrectly .

(e) Avoids tenting (membrane pulling away from the corner).

(f) Sharp corners wear through membranes

(i) Stainless Steel required to resist CCA treatment used in most treated plywood substrates. NOTE: Nailing of any type is unacceptable!!
(ii) Allows for expansion / contraction of ply

(a)  The highest point of the roof or deck is a

minimum of 100 mm below an adjoining floor.
(b)  Membrane up stands extend to a minimum level of 50 mm above the floor level at all walls or parapets
(c)  Water discharges either

i) an overflow in addition to the outlet or

ii) an extra outlet, with both outlets sized to take the full required capacity

When an overflow is provided the overflow shall have a cross-sectional area no less than cross-sectional area of the calculated discharge down-pipe.

1. Is H3.2 CCA treated Construction-plywood (LOSP treatment is unacceptable). Flooring CD grade is recommended where a smooth finish is required.
2. Is 17.5mm minimum thickness laid perpendicular to the rafters/joists in a brick-bond pattern, with 3mm gap between adjacent sheets. Support for the plywood at 400mm centres maximum.

Rubco Butyl Rubber Membrane Page 1 Rubco EPDM Specifications 2013 January 2013
3. Is screwed down using 50mm x 10 gauge counter-sunk 304 stainless steel screws at 150mm centres around the edges and 200mm centres to all intermediate supports and between 7mm and 15mm from the sheet edge, with a 3mm gap between sheets. All installed screw heads are to be below the plane of the adjacent plywood surface.

4. All external exposed edges of plywood sheets to have a minimum 5mm radius.
5. Junctions with all vertical surfaces to have a 20mm triangular fillet installed.

Plywood is laid so as to avoid ponding where possible.
The moisture level of the plywood is to be checked immediately
prior to membrane-laying and confirmed that the moisture content is 20% or below.

8. Plywood surface is clear of dust particles, etc.

d) Installation

All installations are to be undertaken by an approved “The Rubber Roofing Co. Group Ltd” applicator to the best of trade practices.
The applicator is to satisfying his or herself that the substrate complies with clause 2c above and any amendments and any technical bulletins produced by The Rubber Roofing Co. Group Ltd.
Refer to check box schedule for pre-installation substrate review before commencing installation.
Prior to the commencement of any laying of the Rubco membrane the roof substrate is to be swept clean and kept clean during the installation. The substrate is to be checked for protrusions, which shall be removed or eliminated prior to membrane installation.
If the applicator believes that the plywood surface is too porous, then the surface should be primed with a 50/50 solution of adhesive & solvent (refer to sub-clause 2.g.ii.1.g for approved adhesives). Allow this solution to soak in for at least 4 hours before applying full strength adhesive.
Apply 25mm bond-breaking tape to all plywood joints.
Apply Rubco moulding tape to all door openings, external corners,

penetrations and outlets prior to laying the Rubco membrane.
Lay out Rubco E.P.D.M. in a manner that prevents water running onto the laps. Allow membrane to settle for a minimum of 60 minutes before

bonding.
Rubco Butyl Rubber Membrane Page 2 Rubco EPDM Specifications 2013 January 2013
Laps shall be a minimum of 76mm wide.
Apply approved adhesive to the substrate, prior to applying the joint pvc

tape, allow to become touch dry.
Apply the Rubco E.P.D.M. membrane onto the glued substrate, ensuring

that no air is trapped or any wrinkles are formed.
Apply pressure to the membrane with a broom or roller to increase the

adhesion and remove any trapped air bubbles.
All sheet laps to be bonded with Rubco self adhesive lap tape and be a

minimum of 76mm back from the bottom of the sheet to allow for a tidy joint with the lap tape on the other edge joint. First clean the area with Rubco solvent, and then apply the tape primer with a coarse nylon scrubber pad.
When the primer is touch dry apply the lap tape on top and roll out any air bubbles with a rubber roller, while the backing tape is still on.
Remove the exposed backing tape and repeat the process to the underside of the overlapping Rubco membrane.
Appropriately dress membrane into drainage outlets and/or spoutings.
Overflash all exposed moulding tape with Rubco E.P.D.M. or Superflash

tape.
Remove all rubbish and sweep clean.

Concrete substrates must be vented . so form a 600 by 600 grid patten with 25mm p.v.c release tape and a rubco one way vent fixed at the appropriate intersections every 90 square meters.

vi. Apply Rubco moulding tape to all door openings, external corners, penetrations and outlets prior to laying the Rubco membrane.

vii  Lay out Rubco butyl in a manner that prevents water running onto the laps. Allow membrane to settle for 20 minutes before bonding.
viii  Laps shall be a minimum of 50mm wide.
Apply approved adhesive to the substrate, prior to applying the joint pvc

tape; allow to become touch dry.
Apply the Rubco butyl membrane onto the glued substrate, ensuring that

no air is trapped or any wrinkles are formed.
xi Apply pressure to membrane with a broom or roller to increase the glue

adhesion and remove any trapped air bubbles.

All sheet laps to be bonded with Rubco self adhesive lap-tape and be a

minimum of 50mm back from the bottom of the sheet to allow for a tidy joint with the lap-tape on the other edge joint. First clean the area with Rubco solvent, and then apply the tape-primer with a coarse nylon scrubber pad.
When the primer is touch-dry apply the lap-tape on top and roll out any air bubbles with a rubber roller, while the backing tape is still on.
xiv. Remove the exposed backing-tape and repeat the process to the underside of the overlapping Rubco membrane.

xv. Appropriately dress membrane into drainage outlets and/or spoutings.

Overflash all exposed mouldings with Rubco Butyl or Superflash tape.
Remove all rubbish and sweep membrane clean.

January 2013
Excellent
5°C to 40°C.
Between -20°C and 80°C
Excellent bond maintained for at least 10 years. Long service life at high temperatures.
Ensure all surfaces to be bonded are dry, dust free and clean. Apply an even coat of adhesive using brush or roller to both surfaces to be bonded. To acheive the proper coverage rate the typical coverage attained on the membrane is about 4 square meters per liter and about 2 square meters per litre on the substrate depending on surface roughness and porosity)
Some applicators use a primer coat on the roofing substrate, where a 1/1 dilution of Bostik BMA with Bostik BMA solvent (or Bostik #2 solvent) is used. The primer is allowed about 1 hour to dry before continuing with the next coating of adhesive. This will give a better overall bond and easier adhesive application.
Allow the solvent to evaporate until the adhesive film will not transfer to the back of the knuckles when the dried film is touched lightly. Bring the two coated surfaces together and apply as much pressure as possible to form an instant and aggressive bond. Do NOT attempt to reposition the contacted adhesive film. A new coat of adhesive is required if any repositioning is attempted.
The strength of the bond builds up slowly and keeps on increasing even after the first week. The long term heat and ageing resistance is excellent.
