ASC S Silicone Over Metal

Quality Control:

Applicator shall have general knowledge of roofing and a clear understanding of the ASC Roofing System specifications. For all warranties, the contractor must be authorized and approved by the manufacturer for the application of their material. Manufacturer shall certify that materials submitted have been used in like application.

Surface Preparation:

Surfaces must be structurally sound, cleaned, dried, and free of moisture on and beneath the surface. Remove all dust, dirt, oil, loose granules and any other foreign contaminants. Remove any other loose, flaking, or existing waterproof coatings, which may affect the adhesion. For best results, remove all loose gravel, dirt or other contaminants by pressure washing at a minimum of 2000psi, mechanically brooming or vacuuming the surface. Rusted metal should be cleaned with a wire brush. Apply ASC Rust Inhibitor at a rate of 1 gallon per square.

Prior to application water must be swept out of all puddles, waterways, and birdbaths. Prior to application, ponding areas should be treated with ASC F Polyester Fabric set in ASC 1 Acrylic Roof Coating.

Apply ASC 7 Elastomagic Cement to all pipe flashings, skylight flashings, corners, exposed metal joints, flanges, and around drains. It is recommended to repair all holes, leaks and cracks with ASC 7 Elastomagic Cement and ASC F Polyester Fabric. For application of ASC 7 Elastomagic Cement and ASC F Polyester Fabric in the Three Course Installation Method, contact your American Standard Coatings representative.

All metal fasteners shall be addressed with ASC 7 Elastomagic Cement. Address all horizontal seams in the three course installation method.

Acceptance of the substrate is the sole decision of the owner or appointed representative.

Environmental Conditions:

Roofing System ASC S-20-M should be applied in weather conditions that allow for proper application and drying time. The temperature must be 55ºF and rising. Apply on warm, sunny day preferably in the morning to provide maximum cure time. Because the Roofing System is water based, it should not be applied during inclement weather or if inclement weather or temperatures below 55ºF are expected within 48 hours of application. Do not apply when heavy dew or rain is expected within 24 hours. Temperature, air movement, and relative humidity will directly affect drying/curing time.

Storage and Handling:

Do not store at temperatures below 50ºF or above 120ºF. Do not allow to freeze. Do not thin. When transporting this product, be sure the lid is tight and the pail is secured. Do not allow pail to tumble as this may loosen the lid and cause leakage or spillage.

For Further information and advice regarding transportation, handling, storage, and disposal of chemical products, users should refer to the actual Material Safety Data Sheet containing physical, ecological, toxicological, and other safety related data. It is highly recommended to read the actual Material Safety Data Sheet before using the product.

Materials:

ASC S- ASC S Silicone Roof Coating is a one-component, moisture curing silicone rubber roof coating system.

ASC 7- ASC 7 is a high-performance, water-based elastic cement sealing and patching compound ideal for roof repairs on most surfaces. ASC 7 is especially developed to seal cracks, detail areas and surface imperfections. Superior adhesion and flexibility is weather resistant and withstands extreme elongation.

Prior To Application:

Roof Drain Details- Prior to application of Roofing System ASC S-20-M, remove clamping ring and clean as necessary. Embed a modified cap-sheet in drain sump, extending pass the drain edges. Replace clamping ring. Around the outside edge of the drain, apply ASC 7 Elastomagic Cement in the Three Course Installation Method.

Application:

Stir thoroughly before application to achieve a uniform consistency.

Apply ASC P-1000 Acrylic Super Primer at a rate of 1/2 a gallon per square, as needed. Allow to properly cure.

Apply with a heavy-duty paint roller or professional spray equipment. Apply first coat of ASC S Silicone Coating at a rate of 3 gallons per square. Allow to properly cure. Relative humidity will directly affect drying/curing time.
