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.

Customer Questions & Answers

Is this for use on rubber RV (5th wheel) roofs

Asked by: Anonymous
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.

Is this product sprayable?

Asked by: Anonymous
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.

Is it waterproof on a flat roof and what about standing water for short periods of time?

Asked by: Woffer
This product is not recommended for your stated purpose. A more applicable product would be Eterna-Kote S-100.

5 gal. Sta-Kool Elastomeric White Roof Coating is rated 4.6 out of 5 by 68.
Rated 5 out of 5 by from This is great stuff I have a flat roof in Arizona. This coating is heavy, viscous, and sets up in a thick film that stretches nicely with the weather. As the other reviewers said, use a disposable roller, disposable brush, and wear disposable clothes. This coating is sticky and will grab everything until it drys. It's heavy though. I mixed it up in the five gallon bucket then poured it into two 2 gallon buckets to split up the weight. Then I carried the five gallon (now only holding a little over a gallon) up and used it first. I just couldn't drag that big ol' five gallon up a ladder when it was full.

Rated 5 out of 5 by from Staycool for roof coating After reading the reviews about stopping leaks, I bought Staycool 770 to help stop leaks in a 30 year old, still decent, coragated tin, 10' pitch, barn/shed roof. From a number of leaks to down to 1 leak, I can say this stuff works. (Still trying to figure out why I have 1 leak.) This stuff has the consistency of really thin pancake batter. I used a 1/2 in nap roller, wished I had used the recommended 3/4 inch nap roller. Slop it on, thick and liberal. Really a great product. Spread rate is as advertised, 75 to 100 sq feet per gallon. Definitely buy a 2 to 3 gal bucket to transport this stuff to the roof, a gallon or two at a time. A five gallon bucket of this stuff probaly weighs 65+ pounds. And buy a deep roller pan if you are going to roll it on.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from Best I've used.... I have used other roof coatings in the past and find this product to be far superior in terms of it's elasticity and whiteness. I know the elasticity is good as I peeled a dried piece of the product off the side of the can that had dripped down after I poured some product out on to my roof. I pulled on it and it stretched - a lot! The application went well - It has the consistency of a thick paint but rolls out very easily. I applied two coats - although it covered very well w/ just one coat! My living area below has been much cooler since application - typically my a/c would kick on at about 9AM and be running on and off all day. I have noticed lately it comes on around 2PM. I anticipate my electric bill is going to be much lower - I will repost on this once I verify....and no leaks! Great product!

Rated 5 out of 5 by from Easy to work with, covers great in just two coats This coating was easy to apply to the roof of my mobile home. We pressure washed the roof and then used a wire brush on a grinder to clean up the spots that had rusted. We then rolled these rust spots with Rust-oleum Rusty Metal Primer to stop the rust from returning. As an added precaution I painted over the spots with Rust-oleum White exterior enamel to seal the spots further and to cover the red color so it would be easier to cover with the Sta-Kool. We allowed the paint to dry for 24 hrs. and then applied one coat of Sta-Kool with a 9" roller on an extendable pole. You could see through the first coat in some areas. We applied the second coat 24 hrs. later and this coat covered completely. Clean up was easy with soap and water. We used a drill and paint stirrer to stir each bucket of Sta-Kool before we used it. It's easier to buy two or three roller covers with 3/4" nap so you can just throw them away each day. This stuff took about two hours per coat to apply. The initial prep work took about 8 hrs. since I didn't want any problems with the rust in the future so I probably overdid it. It took 10 gallons to put two coats on my 16X80 mobile home and I could not be happier with the results. Will do my rusty barn roof next.

Rated 5 out of 5 by from Saved me 1000's $ on new asphalt roof on my home.. Instead of paying a roofing company 5000$ to re-roof my home I purchased 20 gallons of this product and put it on with a plastic broom from the dollar store. I now have a one piece roof and no lost shingles in the 50 - 70 mph winds we have been having. My neighbors have many bair spots on there roofs. Excellent product and easy to put on. I'm 71 years old , If I can do it anyone can and free shipping to my door. Thanks for a fine product.
