Product Overview

Sta-Kool 770 Ultra White Elastomeric Roof Coating is a tough, highly flexible, rubberized roof coating. This high-performance, 7-year warranted elastomeric roof coating resists cracking and peeling. The coating also provides a highly protective barrier which reflects the sun's heat and destructive UV rays. This helps to cool roof surfaces and reduce interior temperatures. This product is an investment which can actually pay for itself in savings on cooling costs. Covers approx 50-75 sq. ft. per Gal. depending on porosity of the surface.

California residents: see   Proposition 65 information

Yes, this product will work very well on a fifth wheel roof. In fact it will also work very well on travel trailer rules, along with mobile home because it is Elastromeris. It is a very thick bridging over any spots that made me in addition to very much like elastic, expanding and contracting very well causing it not to peel and to stick very well. One of the additional really great the rings about this product is that it is very bright white, causing the to be reflected from the roof very well, keeping it extremely cool in the summer time making cooling inside of the trailer, fifth wheel or mobile home much easier and less expensive. I am a Master Craftsman Painting Contractor and I use this very often and am always very pleased with how well it works. Read Less

Hello Bill and thank you for your question.
Bill this is from the manufactures FAQs page for elastomeric coating products;
******Some rubber roofs can be coated with popular acrylic latex elastomeric coatings, some not. Proper surface preparation is a key to proper adhesion, including removing all chalking, dust and dirt and killing and removing mildew by pressure washing. New formulas designed for rubber roofs may be available; if possible, check with the rubber roofing material manufacturer for suggestions. Finally, be sure to test any coating, especially in "trouble areas" such as shady areas, perennially wet areas, or areas where previous coatings have failed or eroded more quickly.*****
I would recommend contacting manufacturer with detailed description of your roof and inquiring about this application.

Answer: 
Yes you can use a spray rig, unfortunately you need to use a rid powerful enough to run a .031 tip size. most of you DIY home improvement stores will not carry that large of a rig. A Graco GH 130 will do it at a price tag of $5,000. So if you have a lot of jobs requiring it, it might make sense.

Answer: 
Yes it is. Actually, the product only thickens as it dries and expands. However, that being said, I strongly suggest rolling it on with a 1" to 1 1/4" pile paint roller. The sprayer won't apply as thick as the roller would. A regular roller will not apply as thick either.

I myself have never tried to spray it on with a paint sprayer, although the thickness of it spreads like paint and with the right nozzle, it might be done. What I wouldnt do though is to try and thin it down with anything in order to make it spray if the consistency lets say was too thick. This product goes on good with a roller of middle nap, and when put on, broom your surface off real good. This stuff sticks real good and is easy to apply this way. I covered a large area in a short amount of time with a roller and it worked real well so I will stick to putting it on in this manner, and when youre done, just throw the used roller away and start with a new roller the next day if need be. Just a note, use a roller handle with an extension on it and you can adjust your length of travel with ease and it will make it even easier. Read Less

Answer: 
This product is a coating that is designed to be used on sloped surfaces, and it does allow vapor permeability, so it is not "waterproof". If you wish a truly waterproof seal, use the Eterna-Kote Silicone Roof Coating. This product will form a waterproof seal and will withstand standing water. It is our best flat roof sealer and you will be very happy with the results.

Rated 4.6 out of 5 by 67 reviewers.
Rated 5.0 out of 5.0 by Gardner Sta-Kool 5 Gal. 770 Cool Roof Elastomeric Coating Great paint easy to apply and easy clean up. Priced right. October 25, 2016
Rated 1.0 out of 5.0 by No one degree cooler... I put two layers on my flat roof in Key West Florida and the upstairs temperature has not changed at all. It is exactly the same as before. Sorry, in my case it didn't work. Hope it will at least make the roof material last longer. December 31, 2015
Rated 3.0 out of 5.0 by Easy to use I brushed several coats of this product over wood siding that breaks down due to harsh rains. Time will tell how much of a difference this makes, however, I think that it will be helpful. August 3, 2016
Rated 5.0 out of 5.0 by STA-KOOL I coulg not ask for a better result after application on my RV. August 2, 2016
Rated 5.0 out of 5.0 by great price This product was easy to use and much cheaper then other places July 12, 2016
Rated 5.0 out of 5.0 by Great Stuff When i had the old swamp cooler removed from the roof of my 83 year old house, the foll roof was exposed. Sure enough next rain we had a small leak. I purchased Sta Kool and this 53 year old single mom along with my 45 year old girl friend got up on the roof and applied it this phenomenal stuff. No leak and my daughter's room is much cooler in the hot Phoenix sun. Clean up was not easy - I pretty much threw away what i was wearing, but other than that this stuff is GREAT! It was easy to apply with rollers and paint brushes (we threw those away too). I would recommend this and I plan on doing the guest house next! Thanks Sta Kool! March 26, 2013
Rated 5.0 out of 5.0 by Moble Home Roof I just decided to give this a try. At age 66 I got up on the home and used a roller with a long handle. The roof had shingles on it. I wore coveralls and winter boots to keep the coating I spilled off my shoes. It went on pretty easy but hoisting the buckets was a problem so I took half a bucket at a time and used a large cup to take out of bucket and pour onto roof. I went one direction with the first coat and the other way with the second coat. So far, so good and now to wait and see how the results will be through out the year. Our home goes from north to south and we get the hot sun on the west side, which is the worst side for heat most of the day. So far Sta-kool is working for us. Now to see what the rest of the year will be. Last picture is where I need to finish second coating. Needs about 2 gal more to finish. May 26, 2015
Rated 5.0 out of 5.0 by Awesome Product & Value 4.75-GAL. STA KOOL 7-YEAR ULTRA WHITE ELASTOMERIC ROOF COATING is an excellent product and far superior than higher priced competitor brands. The STA KOOL 770 has more elasticity than others I have recently used. The application and clean up are easy as well. June 30, 2013
