10' x20' Shelter

I use three of these things and have never gotten a fabric to last more than year and half in the FLA sun before deteriorating. Had to replace the tarp on one two weeks ago. I was already applying Elasto-Kool 700 on the flat of my roof so said why not.  Took approximately a gallon to do two heavy coats with a roller going different direction for second coat.  First coat seemed to grab and second made it look uniformed coverage when looking up from the backside. We have had three big rains and winds to 35. Tarp looks good and coating holding tight. Hoping the UV blocking will give me at least two years. Regardless at $75 buck for five gallons I am going to start painting the tarps when they are new here on. May tint a gallon to match the house paint color for the two at the shop. As they were both replaced in the last 6 months.

I did the product calculator and it says I should have used 2-4 gallons for a roof. Guesing that is set up for a asphalt shingle or roll surface. Tarp was a gallon or so and I did not try to roll out the paint much aka a heavy coat. hour dry between coat direct sun 57% humidity(wicked dry for my area).
