Because of the Virginia state of the roof, I used 2 more buckets over the original 8 that I ordered. I also placed a polyester membrane as well as the Lanco acrylic primer seal, since I hadn't painted the roof. I was really happy. Make sure to use a 1-1/4 inch roller to paint. Don't skimp on the paint, in other words don't stretch it.

Cannot Overstate the Effectiveness of This!!!
Be me: move into recently flipped home in Florida with a flat roof. Built in 1959. Love house. So nice. We are very happy. Realize the ceilings are 115F on sunny days. Be hot all the time. Get sad :-( Google "Florida home insulation companies;" get more sad when read quotes. Google "roof coatings that make house less like the surface of the sun." Get happy. Enter LANCO! God bless these people. I am an avid DIYer, wood worker, handyman, etc. Father of 3, husband of 1. I stay pretty busy with house projects, especially on this house we bought 4 months ago. The AC unit is a brand new 7 ton system. But the house never got below 80F in the day time with the sun out. AC ran 24/7. I used a laser thermometer and realized the ceilings were hot to touch....uh oh! Weeks of research, quotes, even costing out building a second floor! We were desperate! I had no idea products like this existed. They make a Cool Max version, but for $110 more PER 5 gallon bucket. My roof is massive. I need 16 of these buckets to cover the square footage with 2 coats. So for $88/bucket, I settled on this happy medium version. I started applying with a 6' long 9" wide nap roller. This was decently effective, but it took a very long time to do even a small portion of my roof. I went back to HD today and discovered the Wagner Side Kick, which pumps the liquid through a line keeping the nap roller constantly supplied. Nobody thought it would work, but it works exceedingly well! Ok, so the numbers (all temps taken at same time of day, bright sun light, etc) -Uncoated roof: 170F -Coated roof: 114F -Hottest part of ceiling before White Seal: 115F (yeah....I just....yeah) -Hottest part of ceiling after White Seal: 80F I was skeptical about this product's claims, but I can tell you it has exceeded my expectations in big ways, which is quite rare for me. I can't recall a time recently where I've spent a lot of money on something and thought, "oh man this is gonna be even better than I thought!" It's always the opposite and I'm at the return counter the next day. Not with this. My wife is very concerned with how happy I am and how much I giggle when I take laser temps now. Sometimes I go on the roof and just take the temperature, laugh and climb down the ladder. Then I go inside and do the same thing. I find myself doing things like not sweating through my shorts while sitting in my office, and eating dinner without sweat getting into my meatloaf. This stuff is RIDICULOUSLY reflective. You're basically putting a mirror on your roof. Not in terms of seeing your actual reflection in it, but it reflects basically all the sun light. When applying, wear a stretchy fishing neck gaiter to cover your neck and entire face up to your nose, then very good polarized sun glasses, gloves, long sleeve fishing shirt/rash guard, shoes you can throw away and a good hat. Without all this, you will absolutely get fried. Good luck and enjoy your new (massively cooled) home.
