SMARTCOAT™ 220 Asphalt Emulsion is a versatile, protective, solvent free water-based, all purpose non-fibered roof and waterproof coating ideal for use as a surface preparation for bituminous built-up or modified-asphalt roofing, metal, and masonry surfaces, and for pipes and tanks above or below ground level. SMARTCOAT 220 is made from asphalt emulsified with bentonite clay and water. It is cold-applied, corrosion-resistant, non-flammable while wet, and waterproof when dry, while also resisting most corrosive fumes and spray. SMARTCOAT 220 will not run, sag, crack, or “alligator,” under the harshest of weather conditions. This product meets or exceeds the requirements of ASTM D1227, Type III, Class 1.

Installation
Coverage: 3-4 gallons per 100 square feet per coat as a roof sealer; 6-8 gallons total for SMARTCOAT roof restoration systems.
Precautions: Application over hot applied asphalt may not prevent alligatoring. This coating is not recommended over gravel, rubber or PVC sheet roofing, or old roofs that are too dry and brittle.
1. Clean roof surface thoroughly with SMARTCOAT 100 Roof Wash. Surfaces to be free from rust, dirt, and all other foreign matter. Remove rust with wire brush. A better bond will result if surface is damp when SMARTCOAT 220 is applied, but surface must be free of standing water. All surfaces must have positive drainage.
2. Clean all cracks, holes and damaged areas, repairing when necessary and allow repairs to thoroughly cure.
3. Apply only at temperatures between 50ºF and 110ºF rising and no threat of rain or temperatures below 40 ºF for 48-72 hours.
4. Apply SMARTCOAT 220 by roofing brush, roller, or spray, evenly covering the surface. Allow to dry completely between coats, typically 6-24 hours. In cool, damp weather drying will be slower, 2 - 7 days. For SMARTCOAT roof restoration systems, embed SMARTCOAT 501 Polyester Reinforcement into SMARTCOAT 220 while wet.
5. Clean wet coating with soap and water. Dry coating may be removed with mineral spirits. Use care when handling solvents
