3.02 SURFACE PREPARATION

A. Remove ALL existing roofing and flash down to the roof deck. 1. The (E) roof deck shall be thoroughly inspected and any damaged, wet, dry rot or delaminated decking shall be removed and replaced with exterior grade wood of similar type and size prior to the start of the roofing. All decking shall be inspected and securely nailed to supporting members. Any replacement boards shall fit flush with adjoining boards to create a smooth surface 2. Cracks wider than ¼ inch, or any opening of more than ½ inch shall be covered with securely nailed sheet metal. Sheet metal shall be a minimum 24-gauge. 3. Metal surfaces that may receive sprayed foam must have any loose scale or rust removed and be cleaned / primed with metal primer prior to polyurethane foam application as job conditions dictate.

4. As applicable, examine any sheet metal pans installed over equipment curbs and beneath HVAC equipment for integrity. Report to owner’s representative any deteriorated pans that require replacement. 5. Over the entire roof surface using manufacturers approved fasteners and manufacturers approved fastening pattern install one(1) layer of ½ - inch sheet rock. Lay sheet rock in parallel courses. Stagger end joints in adjoining courses. Apply sheet rock flush to any parapet, curb or wood nailer.

3.03 INSTALLATION - GENERAL

A. Install materials in strict compliance with the written instructions of the manufacturer. Adhere to all applicable local, state and federal regulations.

B. Notify the Owner’s representative in writing of defects in the (E) roof assembly that will be detrimental to the proper functioning of the new roof system. Do not commence work over defective areas until advised in writing by the Owner’s representative of the action to be taken in such areas.

C. The “finished” roof surface shall have sufficient slope to eliminate the majority of any standing or ponding water. 1. Where roof slope is not sufficient it shall be created by the spray- application of the polyurethane foam.

3.04 INSTALLATION - FOAM AND COATING

A. Polyurethane Foam: 1. Liquid components of the sprayed-on polyurethane foam shall be maintained, metered and sprayed under conditions prescribed by the manufacturer of the material and the manufacturer of the spray equipment. 2. Spray in a manner to achieve a full and proper spray pattern. Foam shall be applied in approximately ¾-inch thick passes (lifts) to achieve the specified thickness.3. Apply in multiple passes only in as many squares each day as can be completed to the full specified thickness on the same day. Before resuming spraying operation on the next day, inspect the exposed leading edge of the foam for possible surface moisture. Foam edge shall be considered dry when there is no indication of moisture when blotted with an absorptive material.

4. Surface texture and quality: Cured polyurethane foam shall range from a smoother to a heavy "orange peel" finish. Textures described as "popcorn," "tree bark" or surfaces that exhibit crevices, voids and widespread defects are not acceptable. 5. There shall be no soft or spongy areas or areas with hard or brittle strings or improperly proportioned material. 6. Minimum foam thickness: 1½ -inches in general roof field but varying in slightly greater thicknesses as required creating or maintaining proper drainage.

B. Protective Coating: 1. Preparation: a. The polyurethane foam surface and adjacent surfaces to be coated shall be completely free of degraded foam, foam overspray, grease, oil, dirt or other contaminants which will interfere with proper coating adhesion. b. Surface shall be completely dry and frost-free before coating. c. Any physical damage to the polyurethane foam shall be repaired before coating application commences. d. Oxidized polyurethane foam shall be repaired or replaced. Unisil HS shall be applied within 72 hours of foam application. e. Where foam surface has been sanded, planed or trimmed and the skin removed, such areas shall be given an additional application of base coat immediately after exposure and prior to applying normal base coat to entire area.

2. Waterproofing and Protection System: a. Fluid Applied Waterproofing: Application of coating system shall result in a seamless membrane. (1) Each coat of the Unisil HS shall be applied in a direction perpendicular to the previous coat. Edges of flat roof areas shall be pre-coated in a “picture frame” configuration.

(2) Coating must be applied in two(2) separate coats to ensure proper coverage and cure rate and a pin hole-free continuous film. Each coat must be dry and cured before the next coat is applied. (3) Spray apply Unisil HS at a rate of two(2) gallons per 100 square foot. It is recommended that contrasting colors be

used for each coat to ensure positive, uniform coverage.

(4) The nominal total dry film thickness required to qualify for Untied Coating 15- Year Standard Warranty shall be 26 mils., with a minimum dry film thickness at any location of 23 mils.

b. No traffic shall be permitted on completed roof surface for a minimum of 3 days. (1) Protective coating shall extend up and over polyurethane foam on vent pipes, parapets and other penetrations and shall be terminated a minimum of 3 inches above the foam creating a self-terminated flashing. (2) During coating application, the film thickness applied each day shall be measured by the applicator and recorded on a Quality Control Report Form. (3) Surfaces shall be free from voids, pinholes, and blisters. (4) (As required due to unforeseen circumstances/conditions): If it becomes necessary to leave any newly installed polyurethane foam uncoated for more than 24 hours, the uncoated foam must be inspected by the material manufacturer prior to application of elastomeric base coat. a. Should oxidation of the polyurethane foam occur, the foam surface must be brushed with a stiff broom or mechanically scarred and sanded. b. A minimum ½- inch pass of foam shall be applied over the prepared surface to reseal the surface.

3.05 CLEANING

A. During the course of the work and upon completion, remove excess materials, equipment and debris from premises. Leave jobsite in clean condition.
