We have a 10x10 screened-in sunporch in which my wife would like engineered hardwood installed to match the kitchen (we currently have something that could only be described as 1970s Astroturf in it). When I've installed flooring in the past, I've always left an expansion gap between the first and last course and the wall which was eventually covered up by molding. However, the porch is screened from floor to ceiling so there is no way to install any molding. I don't, however, want a visible gap. Anyone have any ideas? In such a small room, is such a gap even necessary? thanks!
