I air dried 2000 bd. ft. of locust and Ash to side my detached workshop. The building is designed to look like a barn with vertical wood siding. Siding will be oil primed and latex painted. I just finished running the lumber through the planer. Ash is fine but about 30% of locust boards have areas with rot which is sponge like, with varying level of softness. Some have rot on one side and others go through the board. Boards a 6″ to 9″ wide and 11′ long. Boards are 1 1/16 ” thick and will be planed to 1″ final thickness. The walls have OSB and house wrap. I plan to nail 1/4″ thick and 2″ wide strips on the wall under each butt joint (not a true butt joint because there will be a 3/8″ expansion joint).
I have following questions for the professionals and will appreciate any help:
Instead of cutting a big board for a 1″ round area of Rot would it work if I patched it with good wood ?
My siding application is similar to reverse board and batten. Since the building is at the edge of woods is there a possibility that bugs will get under the boards (1/4″ air gap)>
Thanks,
Imran

IAM,
Certainly cutting out the rot and replacing would be fine. In fact, since you're painting it you don't even have to be all that neat about it...just pop out the wood from your hole saw and use a high quality bonding epoxy to glue it in, plane and paint. It's save buying a plug cutter if you don't have one...but all that really matters is getting rid of the rot.
As for bugs, I'm sure some'll find their way in if there's access. I''d suggest using an adhesive sealant...running two beads down your 1/4" strips, one for each board, and sandwhiching the board on top. This will hopefully preven any gaps from opening up as the wood moves around.
Just make sure the woods really dry before priming...get a moisture meter if you don't have one already. And don't forget to prime all sides, especially the bottom after its cut. Use a slow dry oil like SW's A-100 Exterior oil primer and avoid the quick dry ones like Bin Zinnzer, Kilz, etc...they don't last long outside as a whole house primer.
