Hello, we are currently performing installation of prefinished clear cedar siding and ran into an issue we haven’t dealt with before. The wood siding was pre-finished at a local shop, all sides are sealed including any cut ends/joints. Where the siding meets windows/doors we sealed the cut and back caulked up against the window/door, however water is still penetrating the sealant and what we are seeing is moisture wicking into the wood at the cut joints. The finish is a high end semi transparent stain with a clear coat. The house has no overhang so the walls are as exposed to weather as can be. Any tips on how to fix this? The moisture wicking looks awful, we are working on resolving the issue and we’re told that a minimum of 3 coats of finish are necessary to seal end cuts. We did an experiment over the weekend where we took a piece of siding and applied 3 coats of finish to cut ends and let it sit out in the weather for the day and we are still seeing the same moisture wicking problem. Any tips on how to fix or prevent this are much appreciated. Thank you.
