4.2.1 All unnecessary and non-functional equipment and debris shall be removed from the roof.

4.2.2 Substrate must be pressure-washed (TSP is recommended). A minimum working pressure of 3,000 psi shall be used to remove all dirt, dust, previous paints & coatings which are delaminating and waste products (oil, oil-based roof cements, solvents, grease, animal fats, etc.). Roto-spray tip is recommended to expedite metal panel cleaning. Powers vacuuming, brooming, high-pressure air or water washing or any combination that assures a clean surface may be used.

4.2.3 HVAC condensate drains shall be properly routed to roof drains to allow roof membrane and coatings to properly drain and dry.

4.2.4 All roof penetrations, curbs, vent stacks and related roof penetrations are to be flashed in accordance with roof manufacturer's specifications. All laps and wall flashings are to be repaired in accordance with roof manufacturer's specifications.

5.0 PRIMER APPLICATION

5.1 Examine substrate to receive roof coating. Do not proceed with installation of the Southeastern Coatings roof coating until all problem areas have been corrected in a manner acceptable to the manufacturer.

5.2 Treatment of Residual Asphalt: Installer shall make every effort to remove all loosely adhered asphaltic roofing elements. Removal efforts must include the use of pressure-washers, scrapers, wire brushes, wire-wheels, or other similar tools.

All areas with light surface rust must be prime coated with Rust Prime 910 at An approximate rate of 1 gallon per 200 square feet. All areas of roof that have been previously painted should also be primed with Rust Prime 910 Neoprene Primer 940. Rate of Application is also 1 gallon per 200 square feet. All areas with heavier rust should be primed with Neoprene Primer 940 at a rate of 1 gallon per 100 sq ft.

5.3. Curb Flashings: All curb flashings, including cricket details, must be flashed with at least a 6" wide layer of ACRYLIC 210, one (1) layer of POLYESTER FABRIC and then a final layer of ACRYLIC 210 to completely encapsulate the POLYESTER FABRIC. ACRYLIC 210 must be feathered at least 3" beyond each side of the 6" width to allow water to flow over the seam. POLYESTER FABRIC must be cut around all fasteners so that it lies flat. Encapsulate all fasteners using BRUSH GRADE 220.

5.3.1 Dented / Damaged Panels: Installer shall repair dented and/or damaged metal roof panels. Dents shall be mechanically removed to the maximum extent possible. If ribs are broken, Certified Applicator shall cover the broken rib area with a sheet metal cap. Sheet metal caps must be "sealed" to the roof by applying ACRYLIC 210 over the entire rib area to be capped prior to use of new fasteners. Should roof panels be severely damaged, Certified Applicator shall remove and replace damaged areas prior to application of roof coatings.

5.3.2 Fasteners & Gutter Straps: All fasteners must be re-tightened, All stripped fasteners must be replaced with larger diameter fasteners, and the area re-secured by adding a new fastener next to the one that was stripped. All missing fasteners must be replaced. All fasteners must be totally encapsulated with BRUSH GRADE 220. Gutter straps that are fastened above roof panels must be totally encapsulated with BRUSH GRADE 220, including the fasteners.

5.3.3 Gaps: All large or excessive gaps existing between roof panels must be closed or made flush with self-drilling fasteners.

5.3.4 Horizontal and Vertical Seams:

Reinforce all horizontal seams with one of the following options:

1. Apply a 6" wide layer of ACRYLIC 210, one (1) layer of 4" POLYESTER FABRIC and then a final layer of ACRYLIC 210 to completely encapsulate the POLYESTER FABRIC. ACRYLIC 210 must be feathered at least 1" beyond each side of the fabric width to allow water to flow over the seam. POLYESTER FABRIC must be cut around all fasteners so that it lies flat.

2. Apply Caulk Grade 221 into the seam at approximately 60- 80 dry mills. Caulk Grade 221 must extend 2"-3" beyond both sides of the seam allowing water to flow over the area.

The same process should be used on all vertical seams using one of the following two options:

1. Apply a 4" wide layer of ACRYLIC 210, one layer of 2" wide POLYESTER FABRIC and then a final layer of ACRYLIC 210.

2. Apply either Caulk Grade 221 or BRUSH GRADE 220 to the vertical seam with a brush or airless sprayer to seal off any gaps in the seam Vertical seams on a standing seam metal roof do not need to be addressed unless obvious problems exist.

5.3.5 Penetrations: ACRYLIC 210 shall be applied around base of penetration extending 4" on vertical and 4" on base. Embed 4" width of POLYESTER FABRIC using additional mastic, as necessary. Cut POLYESTER FABRIC to accommodate the shape of the penetration.

5.3.8 Ponding Water: Certified Applicator shall make every effort to mechanically eliminate all ponding water areas on the roof prior to application of roof coatings ("Ponding water" is defined as water which does not properly drain and remains for more than 48 hours). Any area with ponding water must be addressed using Butyl 310, over the Acrylic 210 at a rate of 50 square feet per gallon.

5.3.9 Rakes: All fixed rake details for the roof must be secured and sealed with 6" wide layer of ACRYLIC 210, one (1) layer of 4" POLYESTER FABRIC and then a final layer of ACRYLIC 210 to completely encapsulate the POLYESTER FABRIC. ACRYLIC 210 must be feathered at least 1" beyond each side of the 6" width to allow water to flow over the seam. POLYESTER FABRIC must be cut around all fasteners so that it lies flat. If fixed rake metal is fastened to top of roof panel rib and extends back onto the roof, trim off excess metal and follow horizontal seam flashing procedures.

5.4 Ridge Caps: Except as noted, all ridge caps must be flashed with a 6" wide layer of ACRYLIC 210, one (1) layer of 4" POLYESTER FABRIC and then a final layer of ACRYLIC 210 to completely encapsulate the POLYESTER FABRIC. ACRYLIC 210 must be feathered at least 1" beyond each side of the 6" width to allow water to flow over the seam. POLYESTER FABRIC must be cut around all fasteners so that it lies flat.

5.5 COATING APPLICATION (20 mil System)

5.5.1 BASE COAT

5.5.1.1 Apply base coat of ACRYLIC 210 metal roof coating at a rate of 100 square feet per gallon. Base coat shall be applied perpendicular to the ribs of the metal roofing. Dry film thickness shall be approximately 9-10 mils. A stretch factor of 15% should be used as an average to determine actual metal square footage.

5.5.2 TOP COAT

5.5.2.1 Apply final coat of ACRYLIC 210 metal roof coating at a rate of 100 square feet per gallon. Finish coat shall be applied parallel to the ribs of the metal roofing. Dry film thickness shall be approximately 9-10 mils per coat. Total thickness of ACRYLIC 210 is to be approximately 18- 20 dry mils.

5.5.3 Each coat must be allowed to dry for 24 - 48 hours depending on humidity and temperature. The roof is to be inspected for defects, flaws or holidays and repaired if necessary.

ACRYLIC 210 CAN BE SUBSTITUTED WITH SEVERAL OF THE OTHER AMERICAN Southeastern PRODUCTS, CALL FOR DETAILS AND COVERAGE RATES.

5.5.4 Base coat and final coat are to be applied at a rate of 2 gallons per 100 square feet - 1 base coat, 1 final coat. (18-20 dry mil average) In order to apply An 18- 20 mill average a stretch factor must be applied to the metal panel according to rib height. (approximately 15% ).

6.0 RESTRICTIONS / LIMITATIONS
