Decking Boards at 45deg
I am planning on laying my 90x19 kwila decking boards at 45deg over my 50mm joists. The spacing is 450mm, so effective board span will be increased because of the angle. I probably should have reduced the joist spacing, but have spent enough on timber already.
Does anyong know if there are there any inherent problems with laying boards at an angle?
I am doing as the deck wraps around the corner of the house, and it will allow a consistent pattern. Going one way only would gove one side with "short" runs. I can't go two differnet directions and join on the corner due to the post / beam / joist layout.
Thanx
Paul

Should be fine. I think from memory 90mm hardwood decking can officially span max 500mm anyway.

Just done the maths on it and span would be about 630mm. Not ideal but still reckon it will be fine. May be a bit springy underfoot.

I've done it with T/P. Worked fine. Just make sure all your boards span at least 3 joists - good practice anyway.
