Excellent Product. i applied a coating on my winter Home at Melbourne Beach 3 years ago and not only did it completely seal my spray foam over steel roof, but the cooling electric monthly bills became half. The only problem i am trying to resolve is how to purchase (12) 5 gal. buckets of SKU # 548821 in my local summer store #2715 in Grand Rapids, Mi. . @ under $90/ 5gal. bucket, i certainly would be the 1st. in my neighbor hood with an excellent, long lasting New Roof. i can not say enough about the inside thermal reduction after using it. Also: having the Dade County " Approval " means , It Works ! Doug B.

I own a roofing company in the Virgin Islands and we do strictly waterproofing and minor repairs of roofs. We have been using this product for many years now and it is the only water based Acrylic product that we use. When properly applied, according to manufacturer's specs, it forms a superb waterproof membrane on your roof that does an awesome job of repelling water. Best when used on roofs with good drainage and little to no water ponding. Be sure roof is properly cleaned first in order to get a good bond.

Rated 5.0 out of 5.0Â by DrMicha Wrong specs, 300 sq. ft. coverage per bucket!
The coverage area is not 60 sq.ft., it's actually 60-80 sq. ft. per gallon! You should be able to do about 300 sq. ft. with a 5 gal bucket. Read the PDF guidelines on Lanco's website "Apply the first coat by pouring container of LancoÂ® Ultra Siliconizerâ¢ onto the roof and spreading at a rate of 2-4 gallons per 120-240 sq. ft.."

Rated 5.0 out of 5.0Â by CaddyRon Reduced kitchen ceiling temps by over 30 degrees
My metal strips supporting my drop ceiling in kitchen add on to house would be too hot to touch in the afternoon even with lots of insulation. The AC Was working hard. After first thin coat applied on Labor day, the strips were only about 78 degrees when it was well over 95 degrees outside. It rained about 5 hours later and nothing leeched off the roof. Put on 2nd coat 6 days later, is so white it hurts to look at it even with dark sunglasses. No doubt that my next electric bill will be lower as it no longer runs as long to cool the house. This is over a mostly flat roof wtih a gentle slope that mostly dries quickly after a rain. Next question, should I try it on the Architectural Shingles? The light gray color is getting darker after 14 years. Would definitely help cool the attic.

Rated 5.0 out of 5.0Â by MrSunshine Older roof completely looks new!
I had a leak on my South Florida home where the back flat roof was 10 years old and starting to leak. I had just at 2000 square ft of flat roof. I used 7 X 5 gal buckets. The roof looks great. Reflects the sun and the interior of the house stays cool. Be sure to prep the roof. I used a stiff broom to sweep all the debris off and cleaned with a mixture of bleach and water. Allowed to dry for 2 days and then applied Ultra Siliconizer.
I did 2 coats. 1 then the second 24 hours later. It looks like a new roof. Had many roofers give me quotes for a new roof at 12K. Very happy this stuff works as good as it does. I plan on re coating with 1 coat each year. Should last just about forever. All flat roofs in Florida should be coated with this stuff. But of they did the Roofers would be out a job.
