Proper Acclimation: A Necessity

Too often in the contracting field, unnecessary and easily avoidable errors are made due to deadlines and impatience. I’ve been a culprit of this myself. Needing to have a job done by date X, corners are occasionally cut, and it almost always shows.

When a commitment is made to a high-end decking material such as Ipe, Cumaru, or Tigerwood, it’s essential to remember that with the solid durability and resilience of these species come a few concessions. The most important allowance any contractor or homeowner can make to assure the highest quality installation is proper acclimation of the building materials.

If I were contracting an exterior siding or decking job, I would certainly allow the delivered wood to be sorted, spaced, and stacked with adequate spacing to assure proper air-drying for all four surfaces of the material. Cover it, forget about it for a week or two. Catch up on some other projects. It’s so easy to get anxious for delivery of the stock and immediately start pounding through the inventory to finish the contract. Sooner than later, this oversight will show up.

It doesn’t always necessarily happen. But I wouldn’t want to assume the risk of anything but the highest-quality installation. If the homeowner/project manager is already investing several dollars per square foot for a high-end material, the project should likely be budgeted to allow for this crucial acclimation of the lumber. Especially in the instance of finish boards, risers, skirt boards, and other applications which require direct fastening and/or plugging, having as close to a fully acclimated lumber member will prevent splitting from shrinkage or swelling of the stock when it has not yet fully adapted to the local climate.

Less splitting, a truer feel of the finish presentation of the product, and a happier customer are what can be gained by simply exercising just a bit of prudence, and sometimes allowing a job a week or two allowance providing the stock, the builder, the architect, and the homeowner a proper chance at the highest-quality overall installation.
