Yes! I discovered the Silicone Coatings when I was at ABC Supply looking at Stinger Cap Staplers (have decided to manually nail Grip Rite Button Caps for this 7 square job.)
I think they quoted something like $350 for 5 gal.
Then I found the Henry for $229,… and then GacoRoof for $224. But it appears BOTH companies have a PRO line for a lot more money.
What impressed me about the Henri is that the coverage is 1.5 gal per square and not the 1 gal per square of the GacoRoof.
I’m concerned about appearance because on of the flat roofs (1.5:12) is clearly visible from the street and the light gray, although better than white, may look ghetto against the dimensional medium grays I’m using.
Was wondering if granules on top would make a difference, or maybe a darker gray.
Also concerned about the wet slippery characteristic of the silicone coating.
The Henri Pro has a Silicone Coating w/Fibers and a bunch of related specialized product. For instance, SBS seams should be coated with a “butter” grade silicone.l Their information is contradictory: 1 ply Lifetime Warranty, but on the Pro-Grade sheet, you get 20 year with a primer coat and top silicone coat.
Maybe the GacoRoof is simpler to use?
