1.2mm and 1.5mm EPDM ROOFING MEMBRANE:

 Ethylene Propylene Diene Monomer membrane used for flat and low-sloped roofs. 1.5mm is recommended for roofing as it is easier to install in a fully adhered application without getting wrinkles in the membrane. 1.2mm thickness may also be used as a roofing membrane however this thinner gauge membrane is not recommended for the first time installer.

Membrane panels come in a variety of sizes: as small as 3.048 metres x 7.62 mtrs, as large as 12.19 metres  x 30.48 metres and almost any size in between. For your convenience, smaller rolls are folded and rolled on 1.829 metres cores. Larger rolls are on 3.353 metres cores.

The approximate weight of the EPDM membrane is 30 lbs. and 40 lbs. per 100 sq. ft. for 1.2mm and 1.5mm, respectively. Our 1.5mm membrane has a 30-year warranty and our 1.2mm has a 20-year warranty. In addition, EPDM membrane has many other uses, including, most notably, as a flexible pond lining material.

SOLVENT BASED BONDING ADHESIVE:

Used to adhere EPDM membrane to insulations such as plywood, OSB, concrete, block or brick (excluding polystyrene). This yellow coloured adhesive comes in 3.785 litre or 18.9 litre cans. The average coverage is 18.29 sq. metres, 3.785 litres. The coverage may increase depending on the porosity of the substrate.

Apply Solvent Based Bonding Adhesive by rolling onto a clean, dry, grease-free surface. Both surfaces to be bonded must be coated with the bonding adhesive. An open time of five to thirty minutes is recommended before assembly, depending on the ambient conditions. The adhesive should be allowed to dry until it does not stick to a dry-finger. Toluene is excellent for post-application clean up. Avoid prolonged and repeated contact with skin. Finally, shelf life is 1 year when stored at temperature no higher than 32.2°C in unopened containers.

WATER BASED BONDING ADHESIVE:

A user-friendly bonding adhesive designed to bond EPDM to a porous rigid board substrate such as plywood or wood fibreboard. Solvent based Bonding Adhesive is recommended when using OSB Board.

An advantage of Water-Based Bonding Adhesive over Solvent Based Bonding Adhesive is that it needs to be applied to only one surface when bonding to plywood and wood fibreboard and the EPDM membrane can be laid onto the adhesive without waiting for the adhesive to dry.

With this adhesive, you can reposition the membrane during installation thus wrinkles are easily eliminated. However, as the adhesive does not cure for 24 to 48 hours after application, be careful not to move the membrane when walking on it. This adhesive is applied at a rate of 2.5mm – 3mm that is 30.48 – 36.58 sq. mtrs and should not be used to seam EPDM panels together. Care must be taken to ensure this product does not freeze and it can only be applied when temperatures are 22.22°C and above and with no chance of temperatures below freezing within the next 48 hours.

Follow all label directions and precautions. Shelf life is approximately 1 year when stored in a warm room with temperature range between 22.22°C and 44.44°C. This material should not be allowed to freeze. If the product looks like cottage cheese when opened it should not be used.

SEAM TAPE PRIMER PLUS:

A solvent-based primer designed to clean and prime EPDM membrane, prior to application of the tape products. Tape products will not adhere, or perform over time, if Seam Tape Primer Plus is not used. Seam Tape Primer Plus must be applied with a Scrub Pad.

The Primer is also recommended to be used when cleaning membrane surfaces, for example, when using Rubber to Rubber Adhesive as it enhances the bonding of the membranes, compared to using Membrane Cleaner. Seam Tape Primer Plus can be used on galvanized steel, stainless steel, and aluminium/metal drip edge in conjunction with the application of tape products on these surfaces.

    Membrane surfaces must be clean, dry and free of foreign materials. Excessively dirty membranes should be cleaned with the Membrane Cleaner and a clean rag. Seam Tape Primer Plus should be THOROUGHLY stirred before use as the suspended solids tend to settle to the bottom of the container. During use, re-stir frequently (every 15 – 20 minutes). The primer must be used full strength – DO NOT DILUTE.

    Seam Tape Primer Plus contains ingredients which could be harmful if mishandled. It is important to read and follow all label safety instructions. It is important to store product in the original, unopened container, indoors, and out of direct sunlight at temperatures below 44.44°C. The shelf life is approximately 24 months if stored in original unopened containers at temperatures between 33.33°C and 44.44°C.

SEAM TAPE:

Seam Tape is a butyl tape used to adhere one membrane to another. Available in 3” x 7.62 metre and 3” x 30.48metre rolls for roofing applications and also 6” x  30.48metre rolls for landscape/pond lining applications. Seam Tape has been formulated to provide high initial strength in both sheer and peel. Its performance over the full range of rooftop weather is unsurpassed as it is unaffected by heat or cold. Seam Tape Primer Plus must be applied to the membrane surface, with a Scrub Pad, prior to applying the Seam Tape. Roll entire surface with a steel hand roller after mating the surfaces. Lap Caulk is not required when using Seam Tape.

CURED COVER STRIP WITH TAPE:

    Cured Cover Strip with Tape comes in rolls 5″ x 7.62metres, 5″ X 30.48metres and 6″ x 30.48metres. The product is a laminated, cured EPDM membrane and butyl tape rolled on a release paper and used as a “self-sticking” cover strip. Cured Cover Strip with Tape is a black EPDM rubber based product developed for use with Rubber Flat Roof supplied EPDM roofing membranes. Cured Cover Strip with Tape is used to cover cuts in the field membrane or over the exposed fasteners attaching metal drip edging.

Surfaces should be primed with Seam Tape Primer Plus before installation and should be rolled with a steel hand roller after installation. Cured Cover Strip with Tape will not degrade in normal warehouse storage. In time, the release paper may become difficult to remove and for this reason, the recommended shelf life is 12 months.

    Cured Cover Strip with Tape is also used to repair membrane if it is damaged by falling debris etc. Be certain to clean the area to be repaired with Membrane Cleaner and prime with Seam Tape Primer Plus using a Scrub Pad.

UNCURED FLASHING WITH TAPE:

Mouldable EPDM membrane is used for flashing details, protrusions, T-Joint patches and field seams incorporating angle changes. Uncured flashing has the same ingredients as the field sheet. The only difference is it was never put in an oven and cured. Because it is uncured, it can be moulded into the shape of inside and outside corners, pipe flashings, etc. The heat of the summer sun will cause the flashing to cure in much the same manner as the field sheet. Uncured Flashing with Tape has a self-adhesive backing and should be applied using Seam Tape Primer Plus. Uncured Flashing with Tape comes in rolls (12″ x 7.62mtrs, 9” x 15.24mtrs and  6″ x 30.48mtrs).

Store in the original unopened packaging at temperatures between 33.33°C and 44.44°C, until ready for use. During hot weather, do not expose to sunlight or high temperatures until ready for use.

MEMBRANE CLEANER:

The Membrane Cleaner is used to clean EPDM surfaces before using Rubber to Rubber Adhesive and also Metal Drip Edge prior to installing Cover Strip with Tape. Membrane Cleaner should be stored in a well-ventilated area, at room temperature between 33.33°C and 44.44°C in the original sealed explosion-proof container away from all sources of direct heat and ignition. Membrane Cleaner is available in 500mil  and 3.785 litre cans. Membrane Cleaner is extremely flammable and must be kept away from electrical equipment, sparks, open flames and other sources of ignition. Avoid breathing vapours and use only in well-ventilated areas. Handle with impervious gloves and goggles.

RUBBER TO RUBBER ADHESIVE:

A synthetic based polymer adhesive that is specifically formulated to adhere EPDM sheet roofing to itself. Rubber to Rubber Adhesive has long been used for seaming membrane panels. However, the introduction of tape products for seaming membrane has proven to be more user-friendly and superior for long-term performance. It is highly recommended that tape products be used where possible.

For added bond strength, it is recommended that Seam Tape Primer Plus be applied with a Scrub Pad in place of the Membrane Cleaner. In this case membrane cleaner need not be used unless the membrane is excessively dirty or covered with talc. Lap Caulk must be used to seal all seams.

Coverage rate for a 6″ seam, assuming a 7″ application on each surface, is approximately 27.43 metres per 3.785 litres of finished seam. For rubber-to-rubber flashing, coverage is 15.24 – 18.29 sq metres of finished surface per 3.785 litres.

When applying adhesive to both membrane surfaces, follow all label directions, cover cans when not in use and when exposed to lower temperatures restore to room temperature prior to use. Thinning is not possible.

LAP CAULK:

Lap Caulk is designed to caulk exposed  edges of rubber to rubber seams. In addition, it also edges uncured EPDM flashings, tops of Termination Bars and tops of Pipe Boot Clamps. The approximate coverage is 7.62metres per 292 mil tube. Toluene or Xylene are excellent for post application clean up.

WATER CUT-OFF MASTIC:

Mastic serves as a compression gasket preventing contaminates from accessing the roof system where the membrane has been mechanically terminated. Mastic is applied between the substrate and membrane, prior to installing Termination Bars and Pipe Boot Clamps. Coverage is approximately 6.096 metres per 292 mil tube. It can also be used as a temporary overnight sealant or water-stop.

TERMINATION BAR:

    1.524 or 6.096 metres lengths of aluminium with holes 6”s O.C. (on centre), used to mechanically secure membrane at walls, curbs, chimneys, etc. The termination bar may be used in lieu of metal drip edge on fascias. All holes in a Termination Bar must be filled with appropriate fasteners.

PEEL-AND-STICK PIPE BOOT:

Multi-size (254mm to 175mm), pre-moulded, EPDM boot used to flash pipes. Peel-and-Stick Pipe Boot is supplied with tape backing and release paper applied to bottom flange. Pipe Boots should be terminated at top with stainless steel Pipe Boot Clamps, which are included with the product.

SCREWS (665mm) AND PLATES:

There are 250 Phillips truss head screws with No.3 recess and 76mm plates in each box. Screws and plates are used to install insulation board to the roof deck. The fastening pattern should be one set (screw and plate) to every 0.6096mtrs of insulation board for the perimeter of the roof and one set to every 1.22mtrs of insulation board for the remainder. See the “Roof Surface Preparation,” in this manual, for the proper fastening pattern. Other sizes of screws and assembled screws and plates are also available.

SCRUB PAD:

This is a specially designed pad and handle that is used to roughen the membrane surface and apply Seam Tape Primer Plus. As a result, the user comes in contact with the primer. Its use is highly recommended.

STEEL HAND ROLLER:

The Steel Hand Roller is a specially designed hand roller that is of sufficient weight to roll seams without tiring the user. Its use is highly recommended.

WALKWAY PADS:

These are 0.762 x 0.762mtrs skid resistant, moulded EPDM pads that can be stuck to the membrane, in much the same manner as laying tile. These pads come with a peel and stick tape for ease of installation. They are used on lower traffic areas and are often used for walk out decks to protect the EPDM membrane.
