Product 202 Specification Sheet
Description: Rubberized Emulsion Mastic
is an elastomeric asphalt emulsion which has excellent adhesion to most substrates
in good condition. The dried coating can resist the carious thermal stresses typically
found in roofing systems due to this coating’s elastomeric properties. Uses:
Rubberized Emulsion is used as a COMPONENT in the construction of a
cold process roofing system. It is used over a properly prepared and restricted
set of substrates in conjunction with recommended fabrics of coated membranes.
It is not to be used as a coating over gravel roofs that have not been thoroughly
stripped and repaired. Surface Preparation:
Surfaces to be coated must be cleaned thoroughly of all scales, loose mortar,
rust, oil, grease and all foreign matter using a wire brush, sand blast, vacuuming
and other methods in keeping with good practice. Dusty or porous masonry should
be primed with Asphalt Primer and allowed to dry thoroughly before coating with
emulsion. Application: MIX THOROUGHLY
UNTIL SMOOTH. This product may be roller applied, soft brush applied, or airless
spray applied. Airless spray equipment should not use less than an 0.060 inch
spray tip. The normal application is at the rate of 1 gallon per 100 sq. ft. over
metal roofs without fabrics. All other applications should be over smooth roof
membranes at 2 gals. per 100 sq. ft. per coat. When used in conjunction with reinforcement
membrane the application rate is 5 gals./100 sq. ft. Not recommended for use over
gravel or vacuumed graveled roof areas due to unsuitable rough surface area.
Clean-Up: Equipment and brushes may be cleaned
with water and soap while still wet, or by using suitable solvents such as mineral
spirits, kerosene or petroleum naphtha when dry. Use care in handling these solvents.
