Best Practices for Storing Hardwood Plywood

A common concern with hardwood plywood is maintaining the quality of the veneer face during handling and storing. Checking along the grain of hardwood plywood face veneers can occur because of fluctuations in conditions like temperature and humidity, but there are steps you can take to protect your investment.

Here are three articles that Amerhart VP of Sales & Marketing David Destiche recommends if you want to deepen your understanding of best practices for storing hardwood plywood.

Tight Side Out or Loose Side Out?

A Note on Face Veneer Checking in Maple Plywood
 By S. Leavengood, J. W. Funck and J. E. Reeb
 Published in the International Wood Products Journal

This article may challenge your thinking on how to store hardwood plywood. It reports on a study exploring whether checking is greater on the loose side of the veneer and can be reduced with finishing techniques.

The authors found that, “Contrary to conventional wisdom, panels oriented with the tight side of the face veneer oriented out checked significantly more than panels with the loose side oriented out.” They also observed that the application of a clear film-forming finish did not have any effect on checking.

Counter the Effects of Humidity and Temperature

Preventing Checking and Warping in Wood Veneered Panels
 By The Hardwood Plywood Veneer Association
 (now the Decorative Hardwoods Association)

Originally published in the Hardwood Plywood Veneer Association’s common-sense “Ply-Tips” column, this piece focuses on the effects humidity and temperature can have on the moisture level in wood. The association offers several basic steps for preventing checking and warping during all stages of transportation, storage, processing and use.

Key takeaways from the article include: 

  • Protect panels from exposure to the elements during shipment and storage
  • Keep humidity and temperature as consistent as possible during processing and use
  • Add a finish coating to both surfaces to help maintain moisture levels

The association recommends a temperature range of 60 to 90ºF for plywood panels and moisture levels of 30 to 55% R.H. for most parts of the United States.
