DESCRIPTION
Acrylic 211 is a 100% acrylic elastomeric coating for all types of roofs including metal, modified bitumen, single ply, and polyurethane foam. It contains rust inhibitors, and algaecides which makes it ideal for application over most types of roofs including substrates in extremely cold conditions. Acrylic 211 is unique among elastomerics in that its elongation and tensile strength both increase at lower temperatures.
BENEFITS
- Great cold weather performance.
- Reduces daily expansion and contraction (thermal cycling) of metal roofing.
- Reflects 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.
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.
