I am nearing the completion of my deck and although I have used merbau for the decking, I would like to use another species for a 4.5m x 1.6m screen (on LHS of 2nd last photo in the post) that will block out the drive/garage. I was thinking of using cypress (90mmx19mm) for the screen as I like the figured appearance of this species. I am going to finish the merbau deck with cedar colour Spa-n-Deck. However, I would prefer to use a clear finish on the cypress. I would appreciate any comments that you may have on 1) the use of cypress outdoors for a screen 2) the best long-lasting clear finish?
