Plywood: What to Know? How Is It Worked?
The plywood is one of the fundamental elements for those who work with this raw material. Clearly, the most important work in qualitative terms almost always relates to other components such as, for example, solid wood. That is, obtained directly from the trunk of a tree. Without intermediaries, reconstruction processes, or mixing with other materials.
Which is what plywood does instead. And it's clear, at first glance, that there is a significant difference in qualitative terms: solid wood is used for high-quality furniture, load-bearing structures that require great strength; plywood offers lower quality and robustness in some respects. But it remains a fundamental solution in many occasions. Do you want to go deeper?
What Is Plywood, Definition
Plywood is a semi-finished product, that is, one that has undergone a partial processing process, consisting of several particularly thin layers of base material. The key characteristic: these veneers – the name of the wood layers used for the product – are overlapped and glued respecting a particular order. The wood layers always maintain an odd number (3, 5, 7) and the fibers are crossed in a orderly perpendicular fashion to increase resistance and consistency in various uses.
The characteristics of plywood are well-known: geometric stability, that is, it does not deform easily whether it's a flat plane (so it doesn't warp) or a curve. Then, plywood doesn't give resistance problems when coupling with the screw, it's light and easy to work with but also has good aesthetic flexibility since it can be painted, covered, and decorated.
What Is This Material Used For?
As mentioned, plywood cannot be compared to solid wood in terms of robustness and intrinsic product quality. But, at the same time, it offers a series of qualities that make it perfect in many sectors. This also depends on the fact that we have three different types of finished product: for interior, exterior, and marine use. So, plywood is often used to create furniture for the home.
But this is only one of the possible uses: multi-layer wood is also used to set up offices, displays, packaging and shipping crates, boat furnishings, fences. In summary, it works optimally for both applications that need attention to aesthetics and for objects intended for intensive and practical use. As happens in the world of shipping.
How Is Plywood Made?
The technique used to create plywood is that of cross-grain orthogonal fiber. From the turning of the logs, the planes and axes that make up the plywood are obtained. At this point, the panels are crossed so that the grain is crossed and all the benefits of this processing are acquired. For example, wood panels processed in this way are durable, easy to work with, stable, and resistant. Processing also makes the difference between plywood and veneer: the latter is composed of 5 or more layers with a thickness greater than 8 millimeters, plywood is oriented around 3/6 millimeters with a maximum of 3 sheets.
How to Work Plywood
There are several points to consider when working with plywood. Many focus on painting and treatments to make these panels waterproof. Marine plywood is not afraid of moisture while the other versions, if not treated, can have problems with water. To start, you begin with good sanding to make the surface smooth and ready to receive layers of paint. The first should be the sealant to make the surface homogeneous and to waterproof it.
Once the base has dried, you apply the primer which eliminates the porosity of the wood so you can proceed without problems with the paint you prefer. And if you need to make a hole in plywood you can use a simple bit for this material from the Krino catalog.
The range of tools for drilling plywood can also include cup mills that allow you to proceed with generous holes and Forstner bits that have some characteristics: they are precise and are used for large and blind holes. Any more hints? Lewis bits are used especially for laminated wood which is different from plywood.
