Coating System Metal Roof Restoration

1. EC-100 is a water-based, acrylic, elastomeric roof coating formulated to provide a tough, durable, flexible, breathing film for the protection of previously painted masonry, metal and built-up roofing substrates. EC-100 resists the effects of weather, water, abrasion, and substrate movement.

   6. Tensile
      1. Tensile Strength @ 73˚ F D-2370 = 350 PSI
      2. Tensile Strength @ 0˚ F D-2370 = 2573 PSI
7. Permeance D-1653 = 7.03 perms
8. Water Swelling D-471 = 5.14%
9. Fungi Resistance G-21 = zero
10. Tear Resistance D-624 = 63.041 BF
11. Low Temp Flexibility (after aging) D-522 = Pass ½” mandrel bend.
12. Weathering (1000 hrs xenon) = Pass no cracking or checking.

1. Super Putty is a white trowel grade acrylic sealant for use in sealing penetrations and sealing fastener heads.
   
2. A.M.P. Surface Conditioner is black, water borne metal primer containing rust inhibitive pigments.
   
3. Tietex is a 100% stich-bond polyester used in conjunction with Super Putty as a reinforcement for horizontal and vertical seams or other fastener penetrations.

Preparation for Coating

1. Roof Panels
   1. Loose rust, mill scale, and loose, flaking paint must be removed by any of the following: Hand Tool Cleaning to include scraping, sanding, and wire brushing; Power Tool Cleaning to include power sanding, power wire brushing, or power grinding; Water Blasting to include high pressure water blast at not less than 2,000 psi.
   2. Severe chalking, if evident, must be removed to ensure adhesion as must all debris, dust and dirt by using high pressure power wash.
   3. Roof surfaces containing heavy soot, dirt, chemical contaminants, oil, grease, or wax deposits must be cleaned with a surface cleaner and rinsed thoroughly with high pressure water blast. Note: New galvanized panels must be weathered a minimum of six months or treated with a phosphoric acid wash to remove factory oil film.
   4. Rusted areas, once cleaned, must be primed with A.M.P. Surface Conditioner. Previously painted surfaces that exhibit no rust or corrosion need not be primed.
      
2. Roof Penetrations
   5. The base of all roof penetrations, i.e. stacks, vents, etc., must be sealed using Super Putty and Tietex.
   The base of all curb penetrations must be sealed using Tietex and Super Putty.
   
3. Seams
   7. Apply Super Putty to all horizontal and vertical seams, fasteners and penetrations. Install Tietex where voids of greater than 1/8” exist.
   8. All end lap (horizontal) seams, including both sides of the ridge cap, and around skylights must be sealed using Super Putty. Any faulty side lap or (vertical) seams must be sealed with Tietex and Super Putty.
      
4. Ridge Caps
   
   9. Apply Super Putty to seams on and around the ridge caps. Install Tietex where voids of greater than 1/8” exist.
      
   10. All seams on and around ridge cap must be sealed using min. 6” Tietex.
       
   11. All seams around ridge ventilators must be sealed using min. 6” Tietex. Curbed units require Tietex.
       
5. Fasteners
   12. Where loose fasteners are evident, tighten and encapsulate with Super Putty.
       
   13. Replace stripped or missing fasteners using an oversize “repair type” fastener. Add additional fasteners, where necessary, to draw uplifted sheets together.
       
6. Metal Components
   14. Damaged facia, gutters, vents, ridge caps, flashings, etc., must be replaced.

1. General
   For optimum results, the protective coating must be applied after the morning dew has dried and postponed if rain is imminent.
   
2. Application
   1. EC-100 shall be applied by airless spray or 1” to 1 1/4” nap roller. Spray Equipment Recommendations: EC-100 is best applied by air powered, airless spray units. Examples would be Graco 30:1 Bulldog or 45:1 King, Graco GH533 or GH733 gas powered or equivalent models. Tip sizes from 0.35 -.046. A recommended hose is 3/8” nylon high pressure type hose for lengths up to 75 feet. From 75 feet to 200 feet, use 1/2” hose added to existing 3/8” hose
   2. Coverage: EC-100 is to be applied in two coats at the rate of 1 1/2 gallons/100 square feet each coat. On metal roofs with irregular panel design, multiply square footage x 1.15 to calculate actual surface area to be coated.
   3. Skill and experience of the spray applicator are important to the success of the coating application. Periodic checking of the film build is necessary to ensure best results.
   4. Develop a systematic method for application of coating to surface.
   5. Do not permit traffic on completed roof surfaces unless absolutely necessary, and only after complete cure.

1. As work progresses, it is essential to keep equipment clean and in good working condition. After each day’s spraying, equipment should be cleaned as follows:
   1. Flush lines with clean water, followed by mineral spirits or kerosene, to keep metal parts from corroding.
   2. General clean up with same.
      
2. At the conclusion of the project, all equipment should be cleaned and returned to its designated location. Disposal of empty, partially full or full drums should be discussed with the building owner, contractor, or engineer.
