Frequently Questions about Plywood
1. When was plywood invented? Who invented it?
The earliest idea for plywood was conceived in 1797, when Samuel Bentham first applied for patents that covered the machine production of veneers. In those patents, he described laminating layers of veneer with a specialized glue in order to form a single thick piece.
Roughly 50 years later, Immanuel Nobel realized that several thin layers of wood could be bonded together to establish a single durable piece of laminated wood, known now as plywood.
2. Is plywood used for furniture?
Specialized furniture-grade plywood is often used in furniture. This type of wood has a specific hardwood surface veneer, and it is used in bare furniture, wall paneling and cabinetry.
Because of how plywood is treated and stained, there is also a great deal of variety that buyers can enjoy when it comes to purchasing plywood for furniture.
3. Plywood Uses: What is plywood used for?
Plywood uses are determined by the type of plywood used. Consider:
Structural plywood: Great for beams, internal structures, subfloor, shipping crates, wall bracing and roof bracing.
Exterior plywood: This is probably one of the most commonly used types of plywood and is used for walls, outdoor flooring and roof linings.
Interior plywood: Used for indoor furniture, ceilings and interior cladding.
Marine plywood is used for building docks and boats and anything that requires weather-proofed wood.

4. Can plywood be recycled?
The way in which plywood is recycled largely depends on the type used. Untreated, unstained, and unpainted plywoods are often converted into woodwaste.
This can later be turned into compost or mulch. The wood may also be used for animal bedding, landscaping, and raw soil improvement. Solid pieces of plywood may be repurposed by end-users to establish a distressed aesthetic in the desired variety of furniture.
5. What happens if plywood gets wet?
Most varieties of plywood will shrug off rudimentary water damage, and stronger varieties are better equipped to manage extended water damage.
Like most types of wood, even if it is treated against water damage, extended exposure to moisture will start to wear and damage the wood. Untreated pieces will not hold out as well, and warping and rotting will begin much quicker as time goes on.
6. Can plywood be stained?
Plywood is a very easy material to stain because of its efficient construction. Because of how affordable the plywood is, it can also be ideal for all types of practice projects.
Staining plywood will require special gel stains, though preconditioning the wood will allow you to use just about any other wood stain. The right care will allow the wood to have a single uniform color as desired.
7. Can plywood be sanded and polished?
Plywood can both be sanded and polished. Like any other wood, however, it is important to use the appropriate equipment to ensure that the finish appears as desired.
It is recommended for individuals to start with 80-grit sandpaper to get the basic surface down before moving on to finer grits to get a smoother and more vibrant polish on the wood.
8. Can plywood be bent?
Although plywood can be bent, it has to be of a specialized variety, as most other types of plywood will splinter and break if they are bent.
The best variety of plywood available for bending has to be close-grained so that the surface does not separate with bending. Close-grained hardwood faces are ideal, which include plywoods that are made from mahogany, poplar, and birch.
9. How is plywood made? What is plywood made of?
The construction process begins with felling trees. When logs are collected, they are debarked and cut into a very thin veneer. This is an intensive process that results in either a single continuous sheet or pre-measured sheets that will make the arrangement process easier.
After the sheets are dried, they are arranged and bonded using the appropriate adhesives. Once the bonding is finished, the plywood is stamped and graded according to a number of different factors, including the grain and density.
10. How thick is plywood?
Plywood thicknesses vary according to what the pieces are being used for. If the plywood is being used a support, it needs to be thicker and sturdier than if it is being used as a veneer.
Normal plywood thicknesses may vary from an eighth of an inch to as much as one and a quarter of an inch. Specialized types of plywood may have even more variety when it comes to their thicknesses.
11. What is MDO plywood?
MDO, which stands for medium density overlay, is a type of plywood panel that showcases a paintable surface with weather-resistant resin overlay. This overlay is bonded with pressure and heat, and it is designed to stand against the elements much more efficiently than many other varieties of plywood.
12. What kind of plywood is best for flooring?
Interior plywood is one of the most advantageous when used for indoor flooring. Because this type of plywood is only moderately sealed against water damage, it is highly recommended for end-users to apply this flooring system to rooms that do not come in contact with moisture often.
For bathrooms and kitchens, exterior plywood is better designed to resist water damage.
13. What kind of plywood is best for roofing?
Radiant barrier plywood is most often used for roofing. This variety of plywood is designed to be very durable in the face of both physical wear and rain damage.
Roofers often favor using plywood because of its ease of installation and natural strength, though more durable options may be necessary in areas that are prone to frequent thunderstorms.
14. What are the advantages of plywood?
There are advantages of hardwood plywood over other options like wood veneer, hardwood veneer or even solid wood. You may not know it, but plywood is actually stronger than solid wood (depending on the plywood thickness, of course).
Plywood material also often cheaper than solid wood, and can look just as attractive if you go for a decorative plywood or plywood veneer.
However – functionality sometimes trumps design, particularly when comparing commercial plywood with other types more suited for furnishings and decor.
Commercial ply is not known for its aesthetic appeal, and which makes it even more important to know the different plywood types before you buy. This is something to keep in mind the next time you purchase a plywood product.
15. What’s more popular – plywood or drywall?
While both are used for different purposes (for the most part), drywall is more popular based on monthly search volume. Here’s a plywood vs. drywall trend chart:
