PART 3 EXECUTION

3.1 SURFACE EXAMINATION

Verify that all surfaces are ready to receive work. Roof surfaces shall be clean, dry, structurally sound, stable and well secured. The roof surface shall be free of excessive ponding water. A roof surface that allows standing water 48 hours after a rain shall be considered unacceptable. All water shall be allowed positive drainage from the roof. Inspect condition of flashing details adjacent to protrusions, penetrations, roof mounted equipment, curbs, walls, parapets, drains and roof edge to ensure that details are acceptable and will maintain a weather-tight installation after being properly detailed and coated. Inspect parapets to ensure that concrete, masonry or metal caps are sound. Caulk, reinforce or replace as necessary in order to bring parapet and parapet cap into a weathertight condition. Determine moisture content of existing substrate, insulation and deck. Moisture content of 15 percent or greater indicates a potential problem. Work shall not proceed until the cause of high moisture content is verified and condition is corrected.

3.2 SURFACE PREPARATION

3.2.1 CONCRETE ROOFING SUBSTRATE

3.2.1.1 All surfaces shall be clean and dry, and free of any dirt, dust, gravel, oil, surface chemicals or other contaminants that may interfere with optimum adhesion.

3.2.1.2 Any unsound areas in the roof deck, including deterioration, pitted or spalled concrete, excessive moisture content, etc. shall be repaired or replaced.

3.2.1.3 Roof deck areas shall have positive slope-to-drain. Tapered insulation, cant strips, spray-applied polyurethane foam or other similar materials shall be used to build up affected roof surfaces as necessary.

3.2.1.4 Fill any pits or holes in the concrete with concrete repair material so they are flush with the surrounding substrate. Spalled sections of the concrete should be resurfaced using a slurry-coat of concrete repair material, trowelled smooth over the affected area.

3.2.1.5 "Moving cracks" larger than 3 mm (1/8 inch) in diameter shall be routed out and filled using an approved urethane caulk. Cracks larger than 6 mm (1/4 inch) in diameter shall be routed out and fitted with polyethylene backer rod prior to caulking.

3.2.1.6 Inspect parapets to ensure that concrete, masonry, wood or metal caps are sound. Caulk, reinforce or replace as necessary in order to bring parapet and parapet cap into a weathertight condition.

3.2.1.7 All concrete surfaces, whether new or existing, shall be cleaned using an approved biodegradable cleaner, following manufacturer's instructions. Rinse thoroughly with fresh water under high pressure (minimum 2,000 psi - 13,790 Kpa) to remove the solution from the roof. Heavy deposits of dirt or contamination may require agitation with a stiff-bristle broom or similar mechanical scrubber. Allow the roof to dry thoroughly.

3.2.1.8 Prime all concrete surfaces with one coat of concrete prime material at a rate according to manufacturer's instruction to seal and solidify the surface.

3.2.1.9 Reinforce all "moving" cracks and/or seams, control joints, vertical/horizontal interfaces, roof termination points, openings, around the base of all vents pipes and other protrusions, as well as HVAC units and other roof mounted equipment with reinforcement fabric embedded into encapsulation coat. Cut a strip of reinforcement fabric (width depending upon the detail) to the desired length, and center it over the detail area. Apply encapsulation coat liberally from the top side using a brush or roller, working the encapsulation coat into the fabric so as to eliminate air pockets, wrinkles and gaps. Ensure that the reinforcement fabric is thoroughly saturated, encapsulated and fully adhered to the substrate.

3.2.2 METAL ROOFING SUBSTRATE

3.2.2.1 Metal surfaces to be coated shall be clean, dry, sound, and free of dirt, grease, oil, and any other contaminants that might interfere with the adhesion of the elastomeric acrylic coating.

3.2.2.2 All mechanical fasteners shall be checked for integrity. Retighten or replace as necessary. "Stripped out" fasteners shall be replaced using a larger diameter fastener.

3.2.2.3 Unsound rust shall be wire brushed, sandblasted or mechanically abraded to remove all loose rust. Metal panels deteriorated to the point that their structural integrity is compromised shall be replaced.

3.2.2.4 Remove excessive amounts of asphaltic-based or other deteriorated patching/flashing materials if present.

3.2.2.5 Check all seams to ensure that they are tight and flush. Excessive gaps or deflection between panels shall be eliminated by installing additional screws or rivets as necessary to restrict deflection to 6 mm (1/4 inch) or less.

3.2.2.6 All metal surfaces, whether new or existing, shall be cleaned using an approved biodegradable cleaner, following manufacturer's instructions. Rinse thoroughly with fresh water under high pressure (minimum 2,000 psi - 13,790 Kpa) to remove the solution from the roof. Heavy deposits of dirt contamination may require agitation with a stiff-bristle broom or similar mechanical scrubber. Allow the roof to dry thoroughly.

3.2.2.7 All existing "sound" rusted areas shall be primed with metal primer according to the manufacturer's instructions.

3.2.2.8 If the roof has been previously coated with aluminized asphalt of any kind, a penetrating primer must apply to prevent potential "leafing" of the surface. Consult coatings manufacturer prior to application of the acrylic coating system over aluminized asphalt surfaces.

3.2.2.9 Fill gaps between 6 and 13 mm (1/4 and 1/2 inch) at panel seams, joints and protrusions with an approved single-component urethane caulk. Fill gaps larger than 13 mm (1/2 inch) such as at the ridge cap, roof edge and/or interface of dissimilar materials, using polyethylene backer rod or spray applied polyurethane foam.

3.2.2.10 All horizontal (end-lap) seams and vertical (side-lap) seams which have not been factory crimped or presealed, roof terminations and flashings, around drains, scuppers and skylights, and the base of all vents, conduits, HVAC equipment and other protrusions shall be reinforced using one or more of the following methods:

A. Apply base coat acrylic elastomer liberally, using a brush or roller, along the area to be detailed. While the base coat is still wet, embed a strip of 15 to 30 cm (6 to 12 inch) reinforcement mesh for end-lap seams.

For side-lap seams, use 5 to 10 cm (2 to 4 inch) reinforcement mesh, as per detail requirements, centered over the seam, joint or interface. Work the reinforcement mesh into the base coat, applying additional material as necessary to totally encapsulate the reinforcement fabric.

B. Cut a length of 15 cm (6 inch) reinforcement tape to the desired length, peel off the release backing, center over the end-lap detail area and press firmly into place, removing all wrinkles and bubbles. For side lap seams 5 to 10 cm (2 to 3 inch) reinforcement tape may be used. A wallpaper seam roller is helpful in securing the reinforcement tape to the metal deck.

3.3 COATING APPLICATION

3.3.1 CONCRETE ROOFING SUBSTRATE

3.3.1.1 All detail work shall be allowed to dry thoroughly prior to application of the acrylic coating.

3.3.1.2 Immediately prior to application of the acrylic coating system, all dust, dirt and other contaminants shall be blown off the roof surfaces to be coated using high pressure compressed air.

3.3.1.3 Apply encapsulation coat to a small section of roof where the fabric reinforcement will begin. Embed and encapsulate the end of the reinforcement fabric roll so that it is anchored at that point. Roll out a 1.2 to 3 meter (4 to 10 foot) section of fabric, and either spray apply or pour encapsulation coat evenly over the top side at the rate according to the manufacturer's instructions, allowing the fabric to conform to the surface contours. Work the encapsulation coat evenly throughout the fabric using a soft-bristle broom or roller so that it is totally encapsulated, eliminating any air pockets, wrinkles or gaps. Take extra care to ensure that edges of the fabric are well saturated and adhered. Overlap consecutive passes of reinforcement fabric a minimum of 5 cm (2 inch) on each side. Use encapsulation coat to embed reinforcement fabric in this manner over all concrete roofing surfaces.

3.3.1.4 Substrate porosity and texture will determine the amount of encapsulation coat required to saturate and encapsulate the reinforcement fabric. Allow the encapsulation coat to dry thoroughly prior to applying the base coat to the roof.

3.3.1.5 Apply base coat, using airless spray or roller, at the rate according to the manufacturer's instructions.

3.3.1.6 After allowing base coat to dry thoroughly, apply intermediate coat (in desired color), using airless spray or roller, at the rate according to the manufacturer's instructions. Apply intermediate coat in a perpendicular direction to the base coat.

3.3.1.7 After allowing intermediate coat to dry thoroughly, apply finish coat (in desired color), using airless spray or roller, at the rate according to the manufacturer's instructions. Apply finish coat in a perpendicular direction to the intermediate coat.

3.3.1.8 The total minimum dry film thickness required at any location shall be 40 mils (1,016 microns).

3.3.1.9 The top coat shall extend up and over the top of all parapets, as well as all vent pipes and other protrusions, to terminate a minimum of 7.6 cm (3 inch) above the substrate, creating a self-terminating flashing and so as to provide an aesthetically pleasing appearance. To lock in the system at perimeter walls, wrap the fabric up the parapet and under the counter-flashing, or up and over the parapet, extending down onto the front face.

3.3.2 METAL ROOFING SUBSTRATE

3.3.2.1 All detail work shall be allowed to dry thoroughly prior to application of the acrylic coating.

3.3.2.2 Immediately prior to application of the acrylic coating system, all dust, dirt and other contaminants shall be blown off the roof surfaces to be coated using high pressure compressed air.

3.3.2.3 Apply base coat, using airless spray or roller, at the rate according to the manufacturer's instructions.

3.3.2.4 After allowing base coat to dry thoroughly, apply intermediate coat (in desired color), using airless spray or roller, at the rate according to the manufacturer's instructions. Apply intermediate coat in a perpendicular direction to the base coat.

3.3.2.5 After allowing intermediate coat to dry thoroughly, apply finish coat (in desired color), using airless spray or roller, at the rate according to the manufacturer's instructions. Apply finish coat in a perpendicular direction to the intermediate coat.

3.3.2.6 The total minimum dry film thickness required at any location shall be 30 mils (762 microns).

3.3.2.7 The top coat shall extend up and over the top of all parapets, as well as all vent pipes and other protrusions, to terminate a minimum of 7.6 cm (3 inch) above the substrate, creating a self-terminating flashing and so as to provide an aesthetically pleasing appearance. To lock in the system at perimeter walls, wrap the fabric up the parapet and under the counter-flashing, or up and over the parapet, extending down onto the front face.

3.3.3 WATER REPELLENT SEALER AND STAIN APPLICATION

Mixing and application of water-repellent sealer and stain shall be in accordance with manufacturer's printed application instruction. Applicator shall apply a field test on a small inconspicuous area of the actual building surface to determine the best absorption rate to achieve color uniformity, as well as to determine suitability of the application technique.

3.4 CLEANUP

3.4.1 Maintain work and work areas in accordance with clean, safe condition at all times during coating installation. Remove excess materials, trash and debris daily.

3.4.2 At the completion of the project, clean area of any spills and containers, and clean up all roofing debris, leaving jobsite in a clean and orderly condition.
