Among the types of plywood available these days, one of the most commonly used grades is CDX. It is the type of softwood that is inexpensive, but great in quality. The process of manufacturing plywood is similar to all other softwoods. Opposing layers of wood veneers are placed upon each other in the right angles and then glued together. The number of layers added are always odd in number as this ensures the sheets are balanced.

CDX plywood is available in a variety of thicknesses starting from ½ to 1 to ¼ inch thick and even more. In case you are wondering what CDX plywood is used for, here are some common uses:

  • Sub flooring
  • Construction of walls and roofs
  • Construction of boxes and crates

One of the main reasons why CDX plywood is commonly used in construction is because of the fact that it is economical and it is very efficient for construction. If you carefully examine it, you will see that it is only sanded, not finished. This is why the front and back of the wood is rough. Other than this, it also contains some knot and holes.

Plywood is available in different types such as softwood, hardwood tropical, decorative, aircraft, flexible and marine. If you are planning to use plywood for some kind of construction, you need to be aware of its disadvantages too. As the wood is porous, it is heavily susceptible to water damage in case it is exposed to water over time. When the wood becomes wet, it gets heavy. If you place it under the sun for drying, make sure you leave it covered for reducing the risk of absorption.

Other than this drawback, the wood is good to use. The surface of the wood can be painted too. After you are done with the paint, make sure you apply varnish on the surface.
