Plywood delamination can occur for a number of reasons, and it is important to be aware of all of
them before using this sheet material in your own DIY projects. Some of the causes of plywood
Water damage: One of the leading causes of plywood delamination is water damage. This is because, in
conditions of excess moisture, your plywood sheets are far more likely to swell and lose their
initial shape, eventually leading the adhesive bonds or glue within the product to break down
entirely. For this reason, it is always recommended that your plywood is stored in a dry, well-
ventilated area to prevent moisture build-up. However, if you plan to apply plywood to a damp or
humid environment (such as a kitchen or bathroom), it is always important to waterproof it first.
Improper storage: Storing plywood in unsuitable conditions plays a huge part in delamination further down the line.
To expand on the point above, plywood should not be kept in wet or damp environments (unless
it is marine plywood), as exposing your materials to unsuitable conditions, like heat, moisture, or
humidity puts your product at a heightened risk of damage.
Poor manufacturing: Plywood delamination can also occur as a result of poor manufacturing, with some retailers
choosing to opt for low-quality materials (like cheap glues and adhesives) rather than better
quality ones, causing them to fail and break down over time. There is also the possibility that
your plywood has been improperly pressed or cured by the manufacturer. Therefore, it is
essential that, whatever construction material you choose to use, you select a credible supplier
fully stocked with high-quality materials.
