Sunshield is a water-borne combination of high-performance aliphatic urethanes, elastomeric acrylics and resin additives which produces a tough, yet flexible coating film. Designed for performance and durability, sunshield contains 4 unique ceramics to block up to 95% of solar heat entering a structure, due to visual light, ultra violet (UV) and infrared (ir). Sunshield is a flexible membrane with low permeability that can greatly reduce expansion and contraction of a roof. It also prevents corrosion and surface deterioration. Sunshield can withstand large temperature variances without peeling, cracking or loss of adhesion. Sunshield is more than just a white reflective coating as it does not allow a substrate to load with heat, thus preventing conduction of heat into a structure. Sunshield resist dirt, mold, mildew and pollution to increase longevity and reduce surface maintenance. Sunshield is a green coating where low voc and durability is needed and is energy star approved and USDA approved for use in food preparation areas. Sunshield provides a water tight barrier and has a sound dampening quality making a structure more comfortable. Coverage area: 100 sq. ft. per gallon (9 meters’ gal.). Comes in five (5) gal. pails.

Rated 5.0 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Exellent for my application. The back side of my two story house faces west. The lower half is block with stucco applied. The upper half is wood siding. (50 yrs. old) The stucco area got so hot, that you could not touch it. I applied 2 coats of this product and the difference is AMAZING! The temperature is 85-95 degrees and the stucco is barely warm to the touch in the hottest part of the day. I am now working on the wood siding. (Got to replace some of it). Pricey, but well worth it. My AC is working much better and I'm only half done. My neighbor installed vinyl siding 3 years ago and it is warped and distorted on the back of his house, due to the heat. I hope it will last for a few years. May 6, 2014
Rated 5.0 out of 5.0 by *DONT PURCHASE until you read review!* Final Results: House dropped from "Oven Temp" to bearable and the A/C wasn't running constantly. 20 Degree drop. This is drastic as Guam is extremely hot! Cost comparison: It paid for itself in 2.5 months. WHEW! From Michigan to Guam: We don't have extreme heat in Michigan so we had to do some extreme research to figure out how to lower the air conditioning cost while living in Guam. Winter averages 80-90 degrees. Summer is 85-110. We used about (5) 5 GAL drums of this magic on the flat roof. We applied multiple coats with a Ryobi Spray Painter. It did a decent job but be *WARNED*! THIS STUFF IS THICKKK! It's not recommended for sprayers but it can be done... We did it and I was highly pleased with the results. Rent the sprayer for $60.00 and call it a day! A FANTASTIC BUY! December 14, 2014
