AWS Roof Coatings: Elastomeric Roof Coatings Acrylic 211

PRODUCT DATA SHEET

Acrylic 211

DESCRIPTION

AWS Acrylic 211 is an advanced acrylic elastomeric coating that combines high solids emulsion polymers, and potent biocides to provide superior durability, reflectivity, weatherproofing, and mildew resistance. Acrylic 211 is unique among elastomerics in that its elongation and tensile strength both increase at lower temperatures.

ADVANTAGES

Reduces daily expansion and contraction (thermal cycling) of roofing substrates.
Reflects 80-90% of the heat and harmful UV rays of the sun.
Excellent reflective properties which helps to reduce cooling costs. Prevents premature degradation.
Contains a strong mildewcide / fungicide.
Excellent adhesion to various substrates.
Superior resistance to dirt pick-up, helps stay white longer and maintains reflectivity.
Easy to use, easy clean up, non-toxic and VOC compliant water based coating.

BASIC USES

Acrylic 211 is a 100% acrylic elastomeric coating for all types of roofs including metal, modified bitumen, built up roofing, single ply, and polyurethane foam. It contains strong algaecides which makes it ideal for application over most types of roofs.

INSTALLATION

All surfaces to be coated must be cleaned properly. Power washing is recommended. Any existing coating must be checked for good adhesion. Before application, any loosely adhered coating must be removed and bare surfaces must be prepared, cleaned and checked for compatibility.

Acrylic 211 is ready to use. Thinning is not required or recommended.

Spray: Airless sprayer. 3000 p.s.i., 2 g.p.m. capacity with a #027-#031 tip.
Brush: Good quality synthetic bristle brush.
Roller: Long nap roller.

IMPORTANT: AWS Acrylic 211 is designed for POSITIVE drainage. Areas that pond water need corrective measures to eliminate the ponds.

WARRANTY

American WeatherStar warrants that the material supplied will meet or exceed physical properties as published. The contractor guarantees that workmanship will be free of defects in coating application. Since performance of previously installed substrate is beyond the control of American WeatherStar or the contractor, requests for additional warranty coverage shall be subject to prior approval by American WeatherStar.

MAINTENANCE

Periodic maintenance of all American WeatherStar products, including cleaning, will ensure extended service life and maintain reflectivity.
