ASC-100 Flexible Roof Coating

ASC-100 Advantages and Benefits

  • Provides a secure barrier to water penetration.
  • Adheres even damp surfaces without priming.
  • Stays flexible through years of harsh service.
  • Withstands attack from most chemicals, traffic, and severe environments.
  • Retains flexibility in sub-zero conditions.
  • Surface temperature will not exceed 10OF above ambient.
  • Withstands pounding water.
  • Rain will not destroy coating during application.
  • Sustainable roofing system that saves expensive removal and disposal cost.
  • High Albedo reduces heat and lowers energy cost.
  • 100% adhesion of product to substrate.
  • Meets V.O.C emissions regulations to eliminate facility downtime during application.
  • 10 year extendable warranty available for roofs.

ASC-100 Flexible Roof Coating

ASC-100 is a flexible two-part epoxy designed to protect a variety of surfaces including rubber, concrete, foam, plywood, and metal. ASC-100 in conjunction with Poly-lace fabric and ASC Base Coat is also suitable for coating petroleum-based surfaces such as tar or rubber cement. It is especially suited to applications where surface movement may defeat the protection of a rigid coating.

Application Areas

ASC-100 is excellent for waterproof EPDM, built-up, single ply, foam, and metal roofs. It is also suitable for walkways, walls, sumps, and parking garages. The flexibility retained by ASC-100 allows for surface movement caused by thermal shock to most structures.

Preparation

Surfaces must be clean free of grease, oil, films, dust, or any contaminants. Most roof surfaces should be pressure washed to remove any barrier films. Metal must be free of mill scale, oils, rust, etc. Hard-finished concrete should be etched to provide profile or “tooth” for optimal adhesion. These preparation procedures are general guidelines. Consult ASC technicians for further details or special preparation procedures. Roofing specifications are also available for various substrates.

Mixing

The mixing of parts A & B is very important! ASC-100 has a mixing ratio of 4 parts “B” to 1 part “A”. Use a power mixer to thoroughly combine both parts. Mix for at least 1 minute per gallon. Allow idle activation time for at least 10 minutes. Lacquer thinner should only be added after the mixing process is complete.

Application

ASC-100 can be applied by air-less spray equipment, brush, or roller at approximately 100-sq. ft. per gallon per coat. A two-coat application is recommended to help insure complete protection. Surfaces subject to significant movement or other difficult conditions may require heavier applications and the user of Poly-lace. All penetrations or transition or surface materials should be Poly-laced. Surface configuration, weather, or area surroundings may dictate application method.

Dry film Application Rate

13.5 mls.100 sq. ft.
6.75 mls.200 sq. ft.

Application Recommendations

Metal surfaces:1 gal. / 100 sq. ft.
Foam or build-up roofing:1.5 gal. / 100 sq. ft.
Build-up roof after removal of gravel:3 gal. / 100 sq. ft.
Concrete:1.5 gal. / 100 sq. ft.

Thinning

ASC thinner is recommended for best results. Do not exceed more than 2 quart per 5 gallon. Thinning retards cure time and extends pot life.

General

ASC-100 should be applied in well ventilated areas. Surfaces should be free of foreign matter. DO NOT apply near open flame.

Clean Up

Application equipment should be cleaned immediately with lacquer thinner. Use Apple Cider Vinegar to clean hands and skin. Do not allow coating to remain on tools! Once it sets and is cured, it is difficult to remove.

Flammability

Flammable during application. Will not support combustion when cured.
