SECTION 07560
(Fluid Applied Roofing)
The Acrylabs PR25HT Elastomeric Roof System is a fluid-applied, partially reinforced membrane for metal panel, standing seam and flat seam roofs. Combining the Mesh 2000 with successive coats of the 2100 (100% Acrylic/Elastomeric) coating provides a fully adhered, seamless membrane with superior weatherability. The PR25HT is a monolithic, sustainable roofing system that will yield a final minimum membrane thickness of 25 mils throughout the field of the roof and 50 mils at the reinforced areas. Acrylabs coatings are waterborne and meet or exceed all V.O.C. regulatory requirements.
Integral Components of the PR20L System Primers and Accessory Items
2100B Elastomeric Base Coat 2400 Brush Grade Acrylic Sealant
2100HT Elastomeric Finish Coat 3200 Rust Inhibitive Primer
Mesh 2000 Polyester Reinforcement
Installation:
1.) Preparation
Acrylabs coatings are adhesive and require a clean dry surface to ensure proper adhesion. The key to successful coating application is preparation. Pressure washing is the preferred method for removing all oxidation, dirt and contaminants. When pressure washing is not appropriate, consult Acrylabs Inc.’s Technical Department for additional information.
2.) Repair
The applicator needs to provide a sound substrate for the 2002-PR25HT System. All repairs should be made following industry guidelines. These materials should not be applied over rust or corrosion. All rust and corrosion should be removed following SSPC guidelines. If any unusual conditions exist, consult Acrylabs, Inc.’s Technical Department.
3.) Fasteners
Make sure all fasteners are properly tightened and washers are in good condition. Tighten all loose fasteners and replace missing and stripped fasteners with oversized fasteners. Dab all fastener heads with 2400 Brushable Caulk/Sealant to create a water-tight seal.
4.) Flashings & Penetrations
All flashings, terminations, penetrations and any other areas deemed necessary should be reinforced using the following guidelines:
A.) Apply generously a coat of 2100B Elastomeric Base Coat to the area to be reinforced.
B.) Embed appropriate width Mesh 2000 into wet coating, removing all wrinkles and fishmouths.
C.) Apply a saturation coat of 2100B Elastomeric Base Coat.
*These areas must be coated when applying finish coats to insure minimum membrane thickness.
5.) Field Application
Apply 2100HT Elastomeric Finish Coat to all areas at a minimum rate of 1.6 gallons per 100 square feet. Allow to dry. Apply final coat 2100HT Elastomeric Finish Coat to all areas at a minimum rate of 1.6 gallon per 100 square feet.
*When embedding Mesh 2000 into wet coating, a 3” inch overlap is used.
6.) Inspection
Inspect roof and apply additional Acrylabs coating as necessary to insure a final membrane thickness of 25 mils DFT (dry film thickness) throughout the field of the roof and 45-50 mils at the reinforced areas.
This is a general guideline. Minimum material requirements may change based on project specific requirements. Consult Acrylabs’ Technical Department for additional information. Failure of the substrate or roofing systems does not constitute Acrylabs coating or system failure.
