monster boards

These boards have lasted a good long time. Allowing them a week or so to reacclimate to the new space wouldn’t hurt. Consider a ship lap site has replaced one I had been faithful to for over 10 years but left due to their confusing changes. joint at the edges. This will allow for movement and only reveal a small gap. When you rest the boards on the base run do a ship lap as well but rest the panels on “space balls.” this might help the verticle movement as well.

If I understand right that these boards will be over 5’ tall then attach to the wall with a
“sliding dovetail. Rout a dove tail slot in the back slightly bigger than a recieving dovetail would fit. Run this recieving dovetail board along the wall, wax well. You shouldn’t need any nails to install these verticle pieces. Hope I’m not being to confusing.

I would leave a gap and use a batten.

On the other hand, you could go the butt route and hope for the best. If there was any buckling later, you could take down the vertical boards, trim them, and install the batten without too much trouble.

thank you both. i was not considering a sliding dovetail but maybe i should. i was planning to simply butt the boards. i am planning to use screws so i think that i will launch in, see how it looks, then decide if i need to cover the gaps with battens. i will try to post a photo if i pull it off. cheers, jeff
