F. Remove the (E) sheet metal coping over al the short parapet walls and replace with (N). The (N) sheet metal coping shall match, as closely as possible the dimensions of that being removed. As required, install high-temperature S/A membrane so as to cover the top horizontal surface of the short parapet walls and extend down the vertical surface of the short
parapet walls a minimum & maximum of 2-inches. (Notes: (1.) No S/A membrane shall be visible after the (N) coping is installed. (2.) Securely fasten / attach the (N) sheet metal coping to the parapet walls in a manner consistent with good roofing practice.) G. Allow roof and other prepared surfaces to dry completely before proceeding with coating application.
H. Protect all adjoining areas that are not to receive the fluid-applied roof coating system and provide a suitable work station to mix the coating materials as required.
3.02Surface Examination (Prior to commencement of any spray coating application) A. A nuclear scan, infrared scan or multiple and random probes into the (E) roof system using a Demhorst moisture meter must be performed, and any wet or moist roofing substrate must be removed and replaced. (Note: The moisture scan or physical moisture probes must be pre- scheduled and witnessed by the manufacturer’s representative and, or, the owner’s representative.)
1. Any roof repairs and repair tie-ins that are required shall be performed so as to match the (E) roof system and, or be compatible with the (N) coating procedures to be employed. Any and all repair procedures shall be endorsed / approved by the coating material manufacturer and all roof repairs shall be complete before commencement of any spray application.
B. Verify that all roof rehabilitation repairs as indicated in Section 3.08 – Special Instructions, have been completed before commencement of any spray application, C. Inspect roof surfaces to insure they are clean, smooth, sound, properly prepared and free of moisture, dirt, dust and debris.
D. Verify all roof penetrations, mechanical equipment, perimeter edge metal and all other on- roof items are in place and secure.
E. Verify all roof drainage systems are clean and function properly.
F. As required, verify that all air conditioning and air intake vents are suitably protected or closed.
G. Verify all critical areas in the vicinity of the spray application, e.g., parking lots, street parking, etc., are suitably protected or vacated.
3.03 Application of New Elastomeric Sprayed Coatings
A. Application of Aliphatic Urethane Base Coat (Leveling & Priming)
1. To a clean, properly prepared and dry roof surface, spray apply the U95 aliphatic urethane coating over the prepared roof surface as follows:
Urethan Base Coat: Apply U95 urethane coating at a rate of 5-gallons per 100 square feet to yield a uniform thickness of 80 wet mils / 60 dry mils in strict accordance with procedures outlined by Gaco, Inc. (See wet/dry mil chart.) Carry a base coat up all pipe protrusion and walls. ** Allow the U95 base coat to cure a minimum of eighteen (18) hours between coats or until it can be walked on. (**Note: The thickness of 48 wet mils / 36 dry mils, equating to an application rate of 3-gallons per 100 square feet.) B. Application of Polyurea Mid-Coat
1. To a clean, dry roof surface, spray apply the U98782 polyurea coating over the aliphatic urethane base coat as follows:
Polyurea Coat: Apply U8782 Polyurea Hybrid fast set coating at a rate of two (2) gallons per 100 square feet to obtain a 32 mil Wet Film Thickness (WFT) / 32 mil Dry Film Thickness (DFT). Coat
all surfaces including expansion joint covers and flashing. At all perimeter edges and penetrations an extra pass must be applied.
Note: Additional coats of material may be required over rough or granular surfaces to achieve the overall minimum dry film thickness (DFT) requirement. Modified bitumen & built-up roofs have varying degrees of cracks in the surface of the asphalt and bleed-out at seams. With this application it is highly recommended that a test patch be installed to determine how much coating will be needed because asphalt roof surface profiles vary due to weathering and other factors. Applications that do not meet the minimum DFT will not be eligible for coverage under the labor and material warranty provided b the manufacturer. Requirements: It is important to apply the subject coatings in strict accordance with the manufacturer’s guidelines to achieve the specified manufacturer’s warranty and the owner will not allow or accept any deviation that is “less” than the manufacturer’s guideline thickness. (Note: U8782 must be coated within the same day of application. If this timeframe is exceeded, GacoFlex E5320 2-part Epoxy Primer/Filler must be applied at a rate of one (1) gallon / 600-800 square feet to produce 1-2 mil DFT. For rough surfaces, apply the epoxy primer/filler at a rate of one (1) gallon / 250 square feet to produce 1-2 mil DFT. Do not over-apply. When properly mixed and spray applied, E5320 Primer should remain a translucent pink color in its cured state. Allow primer to cure for a minimum of six (6) hours (longer in overcast or humid conditions) before proceeding to the next step in the coating application process. Also, granular and rough surfaces may require more material to achieve minimum mil thicknesses. Application below the minimum mil thicknesses can cause adhesion failure which would result in a non-warrantable application.
C. Application of S4300 Silicone Top Coat (Reflective Surface Coating)
1. To a clean, dry roof surface, spray apply and back-roll the S4200 Silicone Coating over the polyurea mid-coat as follows:
Silicone Top Coat: Apply the S4200 Silicone topcoat at a rate of 2.50 gallons per 100 square feet to yield a uniform thickness of 35+ wet mils / 32+ dry mils in strict accordance with procedures outlines by Gaco, Inc. (See wet/dry mil chart.) Carry top coat up all pipe protrusions and walls. If multiple coats are required, allowed each coat to cure a minimum of eighteen (18) hours between coats or until it can be walked on.
3.04 Field Quality Control
A. Manufacturer’s Field Services: Inspection by the coating manufacturer’s representative is required to verify the proper installation of the system. Any areas that do not meet the minimum standards for application as specified herein shall be corrected at the contractor’s expense. Manufacturer’s inspection or verification shall not constitute acceptance of responsibility for any improper application of material.
3.05 Cleaning
A. Manufacturer’s Field Services: Inspection by the coating manufacturer’s representative is required to verify the proper installation of the system. Any areas that do not meet the minimum standards for application as specified herein shall be corrected at the contractor’s expense. Manufacturer’s inspection or verification shall not constitute acceptance of responsibility for any improper application of material.
3.06 Protection
A. Surfaces not intended to receive the roof coating system shall be protected during the application of the system. Should this protection not be effective any respective surfaces shall be restored to their proper conditions by cleaning, repairing or replacing. All debris from completion of work shall be completely removed from the project site.
3.07 Special Instructions
A. All electrical conduit, water lines and gas lines that rest on the roof surface shall be raised and placed on hard rubber block sleepers. The hard rubber sleepers shall be fitted with an integral Unistrut clamping device. The hard rubber blocking shall be positioned on the roof surface per any applicable code requirements but only after all the roof rehabilitation procedures have been completed and all of the new roof coatings have been applied and are thoroughly dry / cured.
B. Any (E) roof anomaly in the (E) roof field membrane, e.g., blisters, dry voids, mole runs, membrane ruptures or splits, shall be repaired per NRCA and manufacturer guidelines as part of the roof rehabilitation work prior to any spray applications / coating applications. Note: An attempt will be made to identify and mark all roof anomalies with orange paint that need to be corrected. However, prior to the commencement of any spray coating, one last inspection of the (E) roof surface shall be conducted to identify and additional membrane blisters that may have been missed in a previous inspection so that they can also be repaired prior to spray application of any (N) coating.

B. General, Existing Construction:
1. Remove all hardware, hardware accessories, machined surfaces, plates, lighting fixtures, and similar items in place and not to be finish-painted, or provide surface-applied protection prior to surface preparation and painting operations. Remove, if necessary, for the complete painting of the items and adjacent surfaces. Following completion of painting of each space or area, reinstall the removed items by workmen skilled in the trades involved.
2. Clean surfaces to be painted before applying paint or surface treatments. Remove oil and grease or waxes prior to mechanical cleaning. Schedule the cleaning and painting so that containments from the cleaning process will not fall onto wet, or newly painted surfaces.
3. Refer to the manufacture’s Technical Data Sheet for specified product and comply with the requirements regarding application such as: mixing of the components, thinning, pot life, and application equipment such as: roller type and nap length, brush type, tip size and gun type, air and fluid pressure, hose length and hose I.D., etc.
4. Ensure that expectations of humidity, precipitation and temperature (substrate, ambient and material) during application and curing of paints are within the range permitted by the manufacturer.
5. When substrate temperatures are high, care must be taken while applying the paint to prevent formation of voids, pinholes, and bubbles due to the rapid evaporation of solvent.
C. Wood:
1. Clean wood surfaces to be painted of all dirt, oil, or other foreign substances with scrapers, solvent, and sandpaper, as required. Sand smooth all finished surfaces and remove dust. Scrape and clean small, dry, seasoned knots and apply a thin coat of white shellac other approved sealer before application of the priming coat multiple thin coats of white shellac may be necessary to “seal” the knot from “bleeding”. After priming, fill holes and imperfections in finish surfaces with putty or plastic wood filler. Sandpaper smooth when dried. Spot prime over all exposed fillers. Preapproval from the Architect in writing is required before any wood surfaces can be pressure washed. All wood surfaces that are intended to be power washed will need to be identified and agreed upon in advance by the painting contractor, Architect and General Contractor.

5. New Wood must be dry, free of grease, oil mildew, mortar and asphalt spatters and mill glaze. Rough surfaces are to be sanded smooth. Cracks are to be caulked ; door and window trim and joints are to be caulked after surfaces have been primed so as to create a “sandwich” effect between the caulking/putty and the primed substrate. Nail holes are not to be filled. Painting is not to be done during or immediately following foggy, rainy or frosty weather, nor when the temperature is expected to go below 50F before the coating has dried. Avoid painting surfaces while they are exposed directly to the hot sun, and refrain from painting during windy or threatening weather. Pressure treated wood (PTW) must be tested prior to coating to determine proper penetration of coating. Surface must be sprinkled with water to determine absorption into substrate.
If water drops remain on PTW surface, do not paint. If water penetrates immediately into the surface, prepare surface as you would any wood and then prime. Smooth planed clapboards or siding must be sanded thoroughly with 80 grit sandpaper to remove the “mill glaze” to allow proper penetration and adhesion of the paint coating.
If mildew is evident, it must be removed by scrubbing with a commercial mildew wash formulated for this purpose. Caution: Follow manufacturer’s directions; wear rubber gloves, work goggles and protective clothing.
(a) All timber delivered to the job site shall be tested with a moisture meter. All wood testing at or below 18% moisture content shall be immediately primed.
