Customer Questions & Answers

Can you walk on it?

I want to apply to the floor of my terrace that is actually a flat roof over my kitchen. I keep a lounger and chair on it for sitting outside. Will having furniture on it cause damage to the coating? Does it dry hard or soft like an EPDM rubber roof?
Asked by: Trikev
Not recommended for foot traffic or having furniture on. It can handle some light foot traffic, such as doing a yearly roof check or have to do some roof maintenance.

How much erea does a 4 .75 gal of roof coating cov er

Asked by: tim
I think it will depend greatly on the surface you put it on. I put it on an old residential flat concrete roof with a lot of small pits and a few small cracks (no obvious leaking inside the house). Had to use a brush because the roller wanted to slide more than roll. The second coat will obviously need a less lot of the roof coating. And I guess some surfaces like sheet metal in good condition or new wood would need a lot less than old concrete.

Will this product seal leaky cracks and gaps in a flat residential roof?

The roof in question was replaced a few years ago, but the roofing company didn't replace the roofing that extends up the parapet walls. Now water is finding its way in. Will this product fill and seal minor leaks where the flat roof meets the parapet walls and on the walls themselves? If not, does HD sell a product that serves this purpose that can then be coated with white solar-flex?

about how long does it take to dry

I had gotten some water base roofing material before and it took 30 days for it to dry before water could be on it. I need something to dry quickly before it rains, our weather has been odd this year with more rain than we had last winter. Thnaks Jeff
Asked by: Jeff
It will depend on the surface you paint it on and weather conditions. I put some on a flat concrete roof, old and with a lot of small pits and a few small cracks. Ended up using a brush because the roller wanted to slide more than roll, and could not fill the pits. After brushing it on thinly, it was dry to the touch in two hours. This is at about 90 degrees F and 58 percent relative humidity.

4.75 Gal. 287 Solar-Flex White Roof Coating is rated 4.4 out of 5 by 90.
Rated 5 out of 5 by from this stuff works. before i applied it the to roof of our company you could not even touch the corrugated steel roof for even a full second without burning your hand on a hot august summer day. we could not keep the second floor offices cool during noon, employees were complaining every day. So after i applied the treatment it made a huge difference. I sprayed the whole roof 3 coats with a hopper texture sprayer. its been 7 yrs and still stays cool. I had to do repair an ac unit on the roof in middle of august and i could comfortably sit or place my hands on the roof without burning my hands or as. its has luke warm temperature feel to it. its amazing I had my doubts at first but were cooled away. it does wash off a bit at first but still works very good. i sprayed pretty thick fyi

Rated 5 out of 5 by from Works as Advertised! I have central air in my mobile home, but the air conditioner couldn't cool the inside to a temperature that was cooler than the outdoor temperature without running continuously. I applied Henry's 287 to the roof of my mobile home today and for the first time this summer, the inside of my mobile home is cooler than the outside temperature! My air conditioner is running much less and the mobile home stays cool. Only time will tell if the product will last the advertised 7 years, but at this point, i have no reason to doubt that claim. Had I known this product worked, I probably would've used Henry's 887, which has a lifetime warranty.

Rated 5 out of 5 by from Excellent Product I used this coating for a little different application. I actually coated the underside of my wood patio cover. The paint was peeling really bad so I scraped off as much as I could. I had to apply three coast because the old wood kept bleeding through. After I was finished with the third coast it looked as if i had sprayed a coating on the underside of the patio cover. The product filled in all of the cracks so now I have a nice smooth surface. It looks great. I am so happy with the way it turned out that I used the product on my wooden driveway gate. The clean-up was very simple, it washes off with warm water. I recommened this product 100%.

Rated 5 out of 5 by from Great for leak proof roof & saving on electric costs in summer! Great product! Had my handyman do it in a few hours on our flat roof. It had been leaking when it rained a lot and we spent tons of money over a year or more trying to find the leak with no luck. After this was applied, it has been leak free for years now. He did make the point though that the roof needs to be extremely well cleaned off before applying for it to stick properly, and do as instructed and use a couple coats. In addition, my electric bill in the summer has gone way down! Very happy with the cost and outcome!
