Document record
This two-page PDF is a system quick specification for the Ure-A-Sil Roof Restoration System from American WeatherStar. It sets out a coating build-up of Urethane Brush-Grade 522 at seams and flashing details, an Aromatic Urethane 520 base coat, and a top coat of Silicone 410 or High-Solids Silicone 412.
The first page covers the system overview, basic uses, features and benefits, and suitable substrates. The substrates named are built-up roofs, concrete, EPDM, modified bitumen, single-ply membranes and spray polyurethane foam. The same page describes surface preparation by pressure washing and the base and top coat steps.
The second page covers the adhesion test, a pre-inspection list, installation tips such as pressure washing at 3000-4000 psi, and a technical data table. The table lists 12-, 15- and 20-year terms for each substrate, with the coats used and the total dry film thickness in mils. A final block gives solids, elongation and tensile strength for each coating, plus reflectivity and emissivity for the silicone coatings.
