Shiplap Shrinkage, Expansion, Contraction
We are finishing our Monitor Barn addition and oil-stained shiplap will be installed on the interior walls of the heated garage and living space. The contractor is advising us to expect some additional shrinkage even though the boards have been drying for a year outside under cover. The shrinkage would be in addition to the normal expansion / contraction due to seasonal changes here in Vermont.
How much will the shiplap shrink?
Size of gaps?
Any other issues?
Should the shiplap boards be treated with anything to minimize shrinkage?
