1 Description

Sure-Seal EPDM (ethylene, propylene, diene monomer) elastomeric membrane is the key component used in Carlisle roofing and waterproofing systems. The membrane is applied in large sheets to reduce field seams. Exceptional long-term elasticity permits the material to withstand normal building movement without cracking or tearing. It can withstand severe temperature fluctuations and prolonged ozone exposure and remain ultraviolet-stable under constant exposure to intense sunlight. The membrane is available in black or white on black, reinforced or non-reinforced depending on the type of application.

Sure-Seal EPDM is manufactured in standard widths up to 15.24 m (50') and standard lengths up to 60.96 m (200'). Standard thicknesses are 1.11 mm (0.045") and 1.52 mm (0.060"). Special sizes and thicknesses are also available. Material properties and seam strength all exceeds the CGSB 37-GP-52M standards.

1.3 EXECUTION

PREPARATION

Proper decking for the substrate shall be provided to receive the Sure-Seal Roofing System.
Substrates must be clean, smooth, dry, and free of fins, loose or foreign materials, oils, grease and roof cements.
Ensure parapet substrates are suitable for adhering membrane flashings; where sheathing is required, plywood is strongly recommended, minimum exterior grade gypsum board (conforming to CSA A82.27-M1977) is required.
Insulation must be compatible with roof membrane systems.
Ensure plywood substrates are screwed (when EPDM applied directly over decks); alternatively, provide protection between nailed decks and membrane.

FULLY ADHERED MEMBRANE

Position membrane and allow to relax for approximately 30 minutes.
Fold sheet back exposing half of the underside; ensure fold is smooth without wrinkles or buckles.
Apply bonding adhesive evenly without globs or puddles, using a 225 mm (9") wide plastic core short nap paint roller to both the sheet and the substrate.
Allow adhesives to dry until tacky, but not stringy to the touch; roll coated membrane into the coated substrate, avoiding wrinkles.
Brush down the bonded half of the sheet, fold back unbonded half, and repeat the bonding procedure.
Do not apply bonding adhesive to the splice area.
Install adjoining sheet in the same manner, overlap edges a minimum of 75 mm (3").

LOOSE-LAID MEMBRANE

Unroll and position membrane, allow it to relax approximately 30 minutes prior to splicing or membrane securement.
Position adjoining sheets in same manner overlapping edges a minimum of 75 mm (3 inches).

MECHANICALLY FASTENED SYSTEM

Unroll and position membrane and allow it to relax approximately 1/2 hour.
Secure the membrane with in-seam plates 300 mm (1' 0") on center 75 mm (3") away from the edge of the membrane.
Position adjoining sheets to allow a minimum overlap of 150 mm (6").

SEAMS

Fold top sheet of splice area back; clean top and bottom seam areas using splice cleaner and splice wipes or clean natural fibre rag to remove talc on membrane surface.
Apply EP-95 splicing cement to both mating surfaces with medium nap roller in manner and rate specified on container.
Apply a 5 mm (3/16") diameter bead of in-seam sealant 12 mm (1/2") from the edge of the bottom mating surface while splicing cement is drying.
Allow cement to dry, roll top sheet onto mating surface with hand pressure.
Roll splice with 50 mm (2") wide steel roller perpendicular to length of the seam.
Wait at least two hours; apply lap sealant to seam edges and feather with tool provided.

MEMBRANE SECUREMENT

Securement shall be provided at the perimeter of each roof level, and at any angle change where slope or combined slopes exceed 1:6 (2" in 12").
Securement shall be with Rubber Fastening Strip #3 (RFS #3) and acceptable fastener.

FLASHING

Complete all flashing detail and termination according to Carlisle SynTec Systems Canada details; use EPDM Elastoform where required.
