Product Overview

Gardner Sta-Kool, Elastomeric White Roof Coating is a quality flexible, white acrylic latex roof coating. This product resists cracking & peeling, while protecting underlying surfaces. It expands and contracts with the roof's movement to resist damage. The coating provides a protective barrier which reflects the sun's heat and destructive UV rays. In turn, this helps to cool roof surfaces and reduces interior heat gain and lowers cooling costs.
  • 85% Reflectivity: keeps roof surface cool
  • Expands and contracts up to 250% to resist cracking and peeling
  • Highly-flexible, rubberized coating reflects the sun's heat and harmful UV rays
  • Reduces heat buildup and helps reduce cooling costs
  • Please consider the weather when ordering this product, it may freeze in transit, making the product unusable
  • Can be used on cement tile, fiberglass sheeting, bonded gravel roofs, built up roofs, mobile home roofs, metal roofs, RV roofs, and aged roofs previously coated with asphalt, aluminum or tar

The product it's easy to use it takes a long time to dry especially if you're putting it on shaded area to use a thick roller to make it easy.

Good product . Better to put on thick. First coat I used a roller and it was so thin it came off when I walked on it a day later. So put second coat on it with a paint brush nice and thick and waited two days then was just fine to walk on. Stuck well. I did clean the roof before I put any on. It drys and has flat finish and feels like construction paper. Not like some that dry rubbery and are slippery. After second day of drying in the next morning had been some fog and had lots of moisture on the roof of my rv and it was all nicely beaded up. No leaks and no black streaks running down side of RV. Would reccomend. Also great price for five gallons and no primer needed

I ordered this product because of the good reviews. I had two 5 gallon buckets shipped to my house for a 14 x 66 mobile home. The reviews say it goes further than expected. I hired someone to coat the roof for me and he did two coats. I have half of a bucket left. While he was using it he said this was the nicest stuff he had ever put on. It rained about three hours later and none of it came off because I put buckets under the downspouts to check. Highly recommend.

I used this on an old tar covered tin roof. It's Important to scrape off the loose tar, and pressure wash the roof. I applied one coat, and two days later another coat. It's too early to se hold it will hold up, but right now it looks very good. I took photos, but can only post one?

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.

Thanks for your comments. The white coating you applied reflects heat and reduces the roof surface temperature. Depending on the time of the year and amount of roof insulation, you will see differing results on how that translates to interior temperatures.
Keep in mind, you posted your comment during the winter. You will see much lower changes in winter vrs the summer when temperatures are much higher. Give it time and I'm sure you will be very happy with your purchase.

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.

Good product !!! - fast delivery to front door.
Sta-Kool works well. - Took longer than expected, did it over few weeks, every couple days, after getting 5gal. bucket, did a section. - Ordered 1 by 1, when bucket empty, I ordered the next... ended up needing 6 buckets for 1100 sq.ft. home & garage roof. - Did it all by myself, worked well, considering I'm 57yrs. 5'2 woman. - Used 9" & 4" rollers, and 3-4"brush along seems. - Wear clothing you can throw out when done! - I live in High Desert north of L.A., average temp in summer is 90-100's, and I can feel the house is degrees cooler, before turning on the cooler. - And I'm sure when the rare rains come here, Sta-Kool will also protect my roof from leaks. - Product works well even on my asphalt shingles and did not warp or curl, as some other manufacturers warn. - I'm glad I did this, think was a good investment ! (just wish I could afford to buy for a 2nd coat.) - Now I'm only home in neighborhood w/white roof.... guess that makes me president, living in white house ;-)
