SM-1P-14-3G-A — Aluminum-surfaced roof restoration system

Western Colloid specification SM-1P-14-3G-A is a recover smooth surface / cap sheet 1 ply polyester & glass fiber roving reinforced – aluminum surface. The official assembly specification identifies its substrate scope, reinforcement, component sequence and installed application quantities.

• System code: SM-1P-14-3G-A
• Assembly classification: RECOVER SMOOTH SURFACE / CAP SHEET 1 PLY POLYESTER & GLASS FIBER ROVING REINFORCED – ALUMINUM SURFACE
• Published thickness statement: Total System Dry Mils (approximate) 124 mils
• Matched technical set: one complete system specification plus 5 current component bulletins

This specified assembly is a cold process method to upgrade existing roofing, including BUR, Mod Bit, EPDM, TPO and Hypalon. The system is water based and environmentally friendly. It has very low odor. It is reinforced with tough, light weight polyester fabrics and fiber glass strands.

The specification schedules the assembly as follows: No. Component Amount Dry Weight Lb.** 1 Base Coat #298 Emulsion 5 Gallons 19. 2 Polyester Fabric 1 Ply 2.5 3 Top Coat #298 Emulsion 9 Gallons 35. 4 Chopped Glass Fiber Roving (in Top Coat Emulsion) 3 Lbs. 3. 5 Reflective Surface Coating - SilverWhite Aluminum 1.5 Gallons 4.5 Total System Dry Weight 64.0 Total System Dry Mils (approximate) 124 mils ** weight approximate (per 100 sq. ft.) Page 2 2b - SM-1P-14-3G-A revised 10/20 This is one coordinated roof system; a component bulletin alone does not represent the complete assembly.

The published specification states: Total System Dry Mils (approximate) 124 mils. Use the current PDF for wet application quantities, reinforcement placement, allowable substitutions and any fill-coat quantities that are excluded from the stated dry thickness.

Before specifying a recover or upgrade, document the existing membrane, deck, moisture condition, drainage, attachment, surface contamination and repairs. The official specification requires the substrate to be suitable for the assembly; project conditions may require manufacturer review or removal rather than coating.

Submit the exact system code, current specification revision and matched component bulletins. During installation, record surface preparation, reinforcement, batch information, application quantities, weather, cure windows and inspection results so the installed work can be compared with the cited assembly.

Follow the current specification and manufacturer details at drains, penetrations, curbs, seams, fasteners, terminations and substrate transitions. Verify the required elastic cement, polyester reinforcement and coating overlap; detail materials are part of the assembly rather than interchangeable accessories.

Confirm existing-roof moisture, attachment, drainage, adhesion and surface condition before choosing this specification. Check the cited document for temperature, rain, dew, cure and substrate restrictions, and obtain project-specific manufacturer review where the roof condition or required approval falls outside the published scope.

Retain the accepted specification, closeout photographs and repair records. Future edits should add a cited history entry when Western Colloid revises, replaces or withdraws a specification; earlier documents remain identifiable in the archive rather than being erased.

Record the exact specification code, PDF revision and technical-bulletin editions used in the project submittal. A later manufacturer upload does not overwrite that evidence: add the new file as current, archive the earlier edition and preserve the author, timestamp, source and reason for the status change.
