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 Sta kool 770 cool roof Very easy to apply, waiting to see how it holds up in years to come.

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 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.

Rated 5 out of 5 by from Works Fantastic I live in my double wide home half the year. When I returned in the fall I found my porch 2x6's were warping due to heavy summer rains and a very leaky roof. I didn't know for sure it was the roof leak until a bad storm came through and I stepped out on the porch to watch the storm and found the roof, which is nearly flat, was leaking like a sieve. I bought some of the STA-KOOL 770 and painted one coat as I only bought 1 5-gallon tub. The next rain came through and I sat on my porch and was amazed as there were no leaks at all. I have since bought 4 more tubs and painted the entire roof as I live in Arizona and have found that the need for the air conditioner is much less with the painted roof now being white. By the way, my roof has fairly new shingles of a dark color. We have strong winds in my area and I figured the paint over would help keep shingles in place. It does just that. Better heat reflection, water protection and shingle protection. What more can you ask for.

Rated 5 out of 5 by from Works perfect Used on top of my travel trailer. It went on smooth and easy. It was able to seal big cracks around the sky lights. I wish I would have used this years before. It would have saved my cabinet.
