PremiCote 1650
PremiCote 1650 is a plasticizer free, 100% acrylic, single component, bleed blocking, water based, premium quality elastomeric coating for spray, brush, or roller application over most roofing surfaces including metal, single ply and fabric surfaced asphalt emulsions.
Recommended Uses:
This product is intended for use as a highly reflective protective coating for most roofing substrates. May be used over metal, granulated cap-sheet and fabric-surfaced asphalt emulsion. Contact Premium Spray Products for specific application information.
Product Limitations:
This acrylic coating is water based and must be stored and used to prevent from freezing at 32°F (0°C). Do not apply when inclement weather is imminent. Curing is necessary prior to precipitation to avoid washing off the coating or affecting adhesion or physical properties. Do not apply if temperature will drop below 50°F (10°C) within 1-2 hours. The acrylic coatings stop curing below 50°F. Do not apply when the relative humidity is in excess of 85%. Avoid applying late in the day when conditions for dew and condensation are imminent. Material is not intended for ponded water applications. Applications where there is a risk of vapor drive, such as cold storage and refrigerated tank applications should only be made in conjunction with a suitable vapor barrier. This material is not intended for use as a thermal barrier.
Ponding Water:
Warranties do not cover damage due to ponding water. The National Roofing Contractors Association considers ponding water on any roof unacceptable. (See the NRCA Roofing and Waterproofing Manual).

General Properties:
PremiCote 1650 has been formulated for maximum adhesion to most roof surfaces and to provide maximum bleed through resistance over asphaltic surfaces. Adhesion to fabric covered emulsions and granule surfaces is tenacious. Material is developed for maximum water resistance using the highest quality ingredients and attention to detail during manufacturing. This coating has the unique ability to provide a membrane that is not only watertight but also breathable allowing the escape of any trapped moisture vapor from the substrate.
