What is plywood?

Plywood is an extremely versatile man made wooden product and as a result has become one of the most popular materials in the furniture and construction industries. Plywood is constructed by laying down a number of thin strips of veneers, how many will be determined by the thickness of the plywood, in alternating directions and they are then bonded together using glue to produce a strong and stable sheet of plywood. The gluing of these plies in alternating directions, layer after layer allows the plywood to be less susceptible to expansion and shrinkage cause by the moisture content in the surrounding environment and therefore resulting in a sheet much stronger in each direction than a similarly sized board cut from a single tree.
The terms plywood is also used when referring to blockboard and laminboard, which are ‘wood based panel product consisting of an assembly of plies bonded together, some or all of which are wood’

Plywood Bonding Types

For wood Panels, the Glue is the key point relating to the property such as Bonding Strength. Various glues are used when bonding plywood and the type of glue often used depends on the end usage of the plywood.

Interior Plywood

The glues used in interior plywood for example MR -Urea Formaldehyde, are much less resistant to moisture than exterior glues used in exterior plywood. Hardwood species such as birch, Okoume and oak and softwood species such as pine and poplar are commonly used during the manufacturing of interior plywood. This plywood cannot be used outdoors as it is more adverse to the elements than exterior plywood or marine plywood. This plywood is often used in furniture and sheathing where exposure to moisture can be limited.

Exterior Plywood

Examples of the glues used in exterior plywood are WBP (Weather and Boil Proof) Phenolic and WBP Melamine, these glue types are far more resistant to the exposure of moisture than interior glues. Numerous hardwood species are also available in exterior varieties.

Structural Plywood

Also refer to as construction plywood is often used where the strength and stability of the plywood takes precedence over the look of the plywood. The resins used in structural plywood are more often than not WBP Phenolic. No exposure conditions or laboratory tests are known which will degrade hot pressed phenolic glue bonds without destroying the adjacent wood layers. Structural plywood is often covered with a film and the edges are painted with a waterproof paint which further protects the plywood during is usage on construction sites during concrete forms.

Handling and Storage


Like all wood based products plywood is susceptible to the elements and proper care and handling is advised. While most plywood dimensions will not be affected by very small changes in moisture content, larges changes should be avoided as it may damage the quality of the paint base. It is recommended to store interior plywood under similar conditions to those which it will experience during its service. Panels should always be stored on a flat and level surface.


Key point when handling plywood

  • Always protect the edges and corners when handling the plywood.
  • Always try to carry the panels on edge as to avoid damaging the edges, corners and faces.
  • Protect panels at all times from the weather elements.

Care and storage of structural plywood


In order to insure that the maximum usage can be obtained from construction plywood proper supervision should be given when cleaning and repairing the plywood used in the forms. Cleaning should take place immediately after stripping of the form works from the concrete.


When plywood is handled around the construction site, proper care should be given so that the edges and corners are not dented, chipped or damaged. Plywood forms should be regularly inspected. It is important that the plywood be cleaned and dry before the repairs are carried out. The patching of holes for future use of the plywood can be done by filing the whole with a wooden plug and sanding until surface is flat. A metal patch may also be used in cases where unwanted holes need to be filled.
