My friend and I covered (brushed) his rolled roofing (1 layer) with Black Jack fibered roof coating (black). His roof is flat with a 15 degree slope top to bottom. His roof had leaks and it rained 2 days before we covered the roof. The roof felt dry when we started. The temperature range has been 45-85 with some dew in the morning. It has been a couple of days and the covering is blisteringsmall blisters that just seem to contain air. Is it possible moisture from below the roof surface trying to escape? It had been dry for a month before the day of rain that preceded our project, and dry since. Is it the morning dew causing a problem? Most important, is it ruined, or can we roll out the blisters with a rubber roller or something? I'm wondering how long the coating takes to cure as well, as it seems a bit soft to walk on. Any suggestions would be appreciated.
Yes, the pipe threads are the same However - The 40 80 refer to what water pressure the pipes and fittings are designed to handle - 40 psi 80 psi. That's why the pipe wall on sch 80 is thicker. Mixing the two is a bad idea. You'll either waste money buying heavy-duty sch 80 for a system that stays within the 40 psi limit of of the lighter pipe, or you'll waste money and time replacing the lighter parts when they blow out at the higher pressure.
yes, it is possible. for less alarms going off try an alternative.
