Product Overview

Sta-Kool 805 Metal-X is a tough, white elastomeric roof coating that is formulated for exceptional bonding strength to metal roof surfaces. This high performance product also contains rust inhibitors, which provide long-term protection to metal surfaces. Metal-X expands and contracts with the roof's movement to resist cracking and peeling. The bright white finish keeps metal roofs cooler by an average of 50 degrees compared to uncoated metal, thus minimizing heat stress associated when metal roofs expand under the hot sun. Metal-X provides a protective barrier that reflects, seals, and protects from the elements. In turn, this provides a longer life to metal surfaces, helps to cool surfaces and will help reduce interior temperatures. This environmentally advanced formula helps reduce energy cooling demand, is low odor, and low VOC, making it a great choice for your metal roof. Covers approximately 50 sq. ft. - 75 sq. ft. per Gal. per coat depending on porosity of the surface.

Customer Questions & Answers

painting over an old fibered aluminum coating?

I have a turn of the century home in south Florida with a metal roof that was coated with an aluminum fibre coating many, many years ago. It is not peeling, or flaking but rust is starting to bleed through. Is this an ideal product to recoat that?
Asked by: tb69

will it seal leaks on corrugated metal roof

have several leaks tried sealing them seems the whole roof needs to be done as cannot find them.
Asked by: roberto
We recommend using the Gardner Sta-Kool 390 or 440 White Roof Patches. Seal all screw heads with this, and then install the roof coating over entire roof. Metal roofs always leak at the screw holes over time. Good luck with the project and let is know how your job turns out.

Can you apply over paintable silicone caulk repairs (nail holes)?

Asked by: 234
We do have a patch to use with this, but if you used something else, test a small spot first. It should work, but test first.

CAN THIS BE APPLIED WITH A SPRAYER?

The roof is on a large shop. Looking to use vinegar to kill the rust and pressure wash it then scrub where needed and then wash again. Would like to spray the coating on if possible to make the day go faster. Figure I could spray 2 or more coats in a few days faster than rolling, and get a better coverage.
Asked by: Anonymous
Yes, you can airless spray the product in a 10”-12”pattern, 2000 psi with a .021 to .025 spray tip.

Rated 5 out of 5 by from A product that really works This coating is awesome. At an outside temperature of 93 in August I used my infrared thermometer & the underside of my metal back porch roof at 3 P.M was 148 After applying 2 coats of 805 at the same time & temperature the reading was an unbelievable 98 degrees.

Rated 5 out of 5 by from Noticeable difference in temperature We had a "budget" metal shed that we waited a bit long to assemble, so by the time we did it had quite a bit of metal rust showing. We bought STA-KOOL 805 METAL-X METAL ROOF COATING to seal up the metal to prevent further rust and also seal the joints from moisture. We live on a hill with almost no trees in Texas heat. When the coating was complete on the roof and sides, it went from a virtual oven inside to a shed you could actually work in with just a box fan.

Rated 5 out of 5 by from Great results The metal roof of our sunroom was quite rusty. The product overview stated Metal X contained rust inhibitors. From the advice of the staff at our local St Petersburg Home Depot, we ordered the product. The metal roof was cleaned and treated with Prep and Etch. We followed the application instructions and 2 coats of Metal X was painted on with a paint roller and brush. It looks great. The results were to our satisfaction and more.

Rated 5 out of 5 by from Performs well so far... This coating was pretty easy to apply on an old metal roof and has held up well during the first few months of fall and winter. It seems to be a good idea to pay close attention to the manufacturer's recommendations as to appropriate weather conditions and application methods. I applied it to a decades-old tin roof (about 200 square feet, over a garage), which had previously been covered with a black asphalt-based coating. The white elastomeric coating has provided full coverage, but it required two applications (just as the manufacturer had recommended). Because of fall weather conditions, the coating was applied at slightly cooler temperatures than recommended; and unfortunately there was an unpredicted rain shower less than 48 hours after the first application. The result was that the coating took slightly longer to dry, particularly in spots and along seams where the coating had been thickly applied; and several very small sections were washed out by the unexpected rain. Nevertheless, the second coating took care of all of the problems. Patches that were initially applied with water-based products have held up well too, after the coating was put down. The bright white color looks a lot better than the old black, asphalt-based coating. Because it's water-based, clean-up was pretty easy. It should do a good job of reflecting sunlight from the old roof. So far, it's been holding up well and providing a good seal. Of course, time will tell.

Rated 4 out of 5 by from It works! We painted a leaking metal roof on an old mobile home. We pressured wash the roof first. We applied the sealing compound where necessary then painted the whole roof. It rained a week or so later and the leak was gone.

Rated 5 out of 5 by from Theis is great stuff! Paint went on with better square footage coverage than I thought it would. Perhaps I was just not putting it on as thickly as I should have been. I was using a roller on a corrugated metal roof. Since I had paint left over- I just did another coat. Looks beautiful and the barn/shelter is much cooler inside. I bought 2 of these 5 gallon buckets initially and I'm glad I did. This will be very handy to have around.
