I attempted to post more pics but it kept saying "failure to upload" . I do not have a lot of experience with these types of exteriors this will be my first one like this. I have done decks and fences over the years with TWP so a little familiarity with that. The wood is Cypress siding. It has been up for about 6 months here in Nebraska and the GC wants 2 coats of TWP natural and there is $4,500 sq ft of siding.This house pops "back and forth" all the way around between the stucco siding which is blue and needs covered up and the cypress siding. I want to put this on with an airless for best production rate (assuming) i have heard some people don't like the airless idea because of atomizing the colorant. assuming this won't be much of an issue with "natural" TWP although the GC said natural does have a tint. Am i going to have to back brush both coats ? to avoid lap marks from the gun ? assuming i should not put a roller on it for obvious reasons ? i did wonder about rolling horizontally "with" the siding like one would do on a deck ? but this is a 3,300 sq ft million dollar house on a lake and needs to look top notch. Any advice/opinions/experience would be greatly appreciated.
