Product Overview

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 Gal. (9 meters Gal.) comes in five (5) Gal. pails.

Customer Questions & Answers

Can this be painted over to match the rest of the house?

Can this be painted over to match the rest of the house? Or is it the white reflective color that assists in temperature reduction more than the 4 ceramics barrier? white is OK but I would love it if this reflective barrier still had the same success rate even if it was used as a primer. This is a great question however from the lack of response to the past questions, I suspect this site isn't maintained for responses. MK 9/14/15

Sunshield is designed to be the first layer of defense against solar heat loading. So painting over it would not be advisable. Sunshield has proprietary nano particles of specific ceramic material that blocks all 3 forms of solar light energy. Sunshield can be tinted to light pastel colors but will loose some of its ability as it is a high solid coating and will require a lot of dye to induce color, so the darker the tint, the more the nano material within the coating is tinted, which impacts performance. Performance wise, you will loose up to 30% on average when Sunshield is tinted to pastel colors. Most people only tint Sunshield for exterior side wall applications and as recommended, they do not tint Sunshield for the roof. Additionally, Sunshield has very little density and this is very important for performance. For example, a piece of paper when left outside will never be physically hot to the touch regardless of the ambient temperature or how long it has been in the sun, because the paper lack density. The proprietary material used in Sunshield is 50 times lighter than paper and thus Sunshield cannot load and hold solar heat (same as with paper), so the surface coated with Sunshield stays at an ambient surface temperature, even on bare metal, regardless of how hot it is outside. So if applying to a metal roof, for example, (metal will conduct heat extremely well) if it is 85F ambient temperature outside, then the surface temperature of the metal roof will be 85F or within a few degrees of 85F, if it is very humid, rather than a 160-180F surface temperature without Sunshield.. This means that less heat will load on the metal roof and thus, less heat is available to transfer inside of the building. Because Sunshield cannot load the solar heat, it is a proactive means of controlling solar heat loading,.allowing only 5% of the solar heat to load on the surface of the roof.. If buildings do not load with heat, then you do not need as much air conditioning to remove the hot air. Prevention is better than cure. Because only 5% of the solar heat loaded during the day, the air conditioner does not run all through the night.. Additionally, because the surface of the roof stays at an ambient temperature level when coated with Sunshield, Sunshield significantly prevents roof failure as a result of contractions and expansions, which occur when the roof has loaded with heat all day and then experiences an evening rain shower. Sunshield can be used on any roof surface type. When used on metal no primer is needed. No primer is required when used on concrete, but without the use of the primer, the spread rate will be reduced as the concrete is very dry. . When used on asphalt, rubber, modified bitumen, shingles, etc.. the Superbase primer sold at is needed. Sunshield can be used in any application where solar heat loading is a problem, commercial and residential,

2nd coat required?

Was comparing this with Gardner Model # SK-7805 which is only $73.00. The reviews on that one state it needs a second coating for desired results. Does this one need a 2nd coat or is one enough? Also does it really cool that much better than the cheaper versions which are about 1/3 of the price?
Asked by: Rich
Sunshied should be applied at 17 wet mils. If applied by roller use 1 3/4 inch nap roller and it will take two passes over the surface area on average the achieve the desired coating thickness. If applied by airless sprayer, if is imperative that all the filters be removed from the spray pump and gun or it will filter the nano particles that provides the performance. If using an airless sprayer, it can be applied in one pass by overlapping each pas 50% Sunshield will perform as advertised and ensure that the surface stays at an ambient surface temperature no matter how hot it is outside, even on bare metal, it will not load with heat and will always be cool to the physical touch. No other product can do this. Cheaper products work only by reflection. The problem is that roof and external surfaces will not stay clean and shinny. Sunshield lacks the density to hold and load the heat and that is why the surface stays physically cool even on metal at 2Pm when it hottest outside. Sunshield will provide long term performance and the cheaper products will loose performance after about 6 months because the are only white elastomeric coatings. If solving the worlds energy problem was as simple as painting surfaces white, then the world would have done that a long time ago. The reason the world has not is because it is not the solution. Sunshield preformance material is inert non conductive materials and will provide long term performance.

Rated 5 out of 5 by from Do This Before adding Insulation I have a Spanish style home built in 1927 that had no insulation. Everybody says insulate and save heating and cooling bills. I say do your research before you do what I did. HD came and sold me attic insulation and they blew in R40 everywhere and higher values in places. Before I had it blown but after I signed a contract to have it done I found out about this product. I have a flat roof, live in sun soaked So CAl and I painted two 5 gallon buckets on my roof. It immediately dropped the attic temp at least 20 degrees and inside the house almost 12. At night the house would cool to just above outside temp. Then I get the attic blown and guess what. The house would cool better as long as we ran AC but at night the house was hotter. I hadn't painted the entire roof and bought more. I just finished painting a second coat and one on the garage. Now the house is cooler, in fact temps dropped 2 degrees when we painted the roof and the AC now cycles. The garage dropped 10. If I had it to do over, I'd only paint the roof. and add maybe R19 max in the attic. Insulation holds heat. Sunshield BLOCKS heat. It's better to keep it out than remove it.

Rated 5 out of 5 by from I used Sunshield on my 500 s/f steel patio cover.... I used Sunshield on my 500 s/f steel patio cover. It works. I can put my hand up to the underside and hold it there now in the middle of the day. Before, it was too hot to touch. Very good product, even better when it's on sale. Get somebody who knows what they're doing to paint it on, it's thick.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from *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!

Rated 5 out of 5 by from Outstanding Product! Great product. We have a refinished attic with a flat roof that transfers an incredible amount of heat during hot summer days. It has separately zoned AC and a supplemental window unit but nothing really works during 95+ degree summer days. Sunshield has reduced the temp from 92-95 degrees room temp in late afternoon to 83-85. That's remarkable. Pretty easy to install, too, which my son and I did ourselves. You will need to use their sealer before applying the Sunshield. Still more than worth the cost and effort.

Rated 4 out of 5 by from Radiant Barrier Paint I used this paint to cover my exterior wall facing west to the sun. I gotta say the rooms actually feel cooler. I should recommend anyone who plans to paint block should use a thick primer first so that you can cover more easily. This paint is very thick and you should use a wide roller. The reviews helped me to decide if the investment was worth the risk.

Rated 5 out of 5 by from worth every dime I purchased this paint to cover my dad's roof, just to try it out. I noticed the change immediately, we had to order a few more 5 gallon buckets to finish covering the rest of it, but definitely worth it
