Marine Plywood Advantages And Disadvantages

Plywood is an important material for the furniture and construction industry. There are many types of plywood that are used in different places. But marine plywood is the highest grade of plywood used for long-term use. 

Marine plywood performs quite well in both dry and wet places. Also, the chances of termites and fungus inside it are very less. It is durable for a long time under any weather condition. Durable face and core veneers are used to make marine plywood.

Many people think that marine plywood is waterproof plywood. But this is not true, marine plywood is not 100% waterproof. The quality of marine plywood is better than that of normal plywood. Due to its quality, this plywood is used in making boats and boat parts. 

How Marine Plywood is made and why it is stronger?

Douglas fir and western lunch wood are used to make marine plywood. The timber of these woods is cut into thin layers. Many layers are glued together with wooden glue. After high pressure and heat treatment, it makes it a solid plywood sheet. Read Why Is Plywood So Strong Compared To Others?. let see the Marine Plywood Advantages And Disadvantages

The Advantages of marine plywood

1. Good Water Resistant

Marine plywood is good water-resistant. It is also long-lasting after exposure to water. Therefore it is useful for making parts of boats and ships. But it is not completely waterproof, so it needs to be changed after a few years or couple of decades.

If you are using Marine Plywood for an indoor and outdoor project, then it can run for decades.

2. Surface finish

Marine plywood is made from solid veneer wood. Because of this, the surface of the plywood is quite fine and gives a wooden appearance.

Plywood can also be used without any paint and mica. But using paint and mica makes it more durable.

Being a smooth surface, it holds the laminate well. Being a fine surface, paint and polish can be easily done after grinding of sandpaper with light hands.

3. Durability

Marine plywood is more durable than normal plywood, it maintains its strength even in bad weather. It remains sustainable for several decades in exterior and interior projects.

4. Flexibility

This Plywood is made of many thin pieces of wood. Because of this, it can be easily folded as per requirement. Marine Plywood is strong as well as flexible. So that when it is pressed more on the plywood, it turns and it does not crack like wood.

5. Uniform Strength

The plywood does not have knots so that there is general strength throughout the plywood. Douglas fir wood is used to make marine plywood. Which has knots but does not have holes in knots. So that it is strong. While manufacturing plywood  Each of the other veneer layers is placed in the cross of the first. This method makes it stronger.

6. Availability

Marine Plywood is easily available in the wood market. It is available in many thicknesses and lengths. This is available in large sizes compared to solid wood. It is available in various thicknesses ranging from 6 mm to 32 mm.

There is no joint of any kind in its sheet, due to it being a solid sheet, its maintenance is much easier.

 7. Good Density

 Marine Plywood having a good density Holds the screw and nail very well.

8. Good Termites Resistant

Chemicals are used to protect marine plywood from termites and ants. Because of this, there is no need to care much about marine plywood.

The Disadvantage of Marine Plywood

1. Price

It is more expensive than Medium Density Fiberboard (MDF). Because there are many processes in its manufacturing. Like extremely high heat and pressure treatment.

2. Bend issue

As we know it is made of thin layers. Therefore, it bends easily when it is overloaded. Support is required to prevent this. When we use a large sheet without any support, there is more possibility of the bend.

3. Not Waterproof

If we talk about wood then 100% nothing is waterproof. Marine plywood is made of hardwood. so that it performs well even after coming in contact with water. Waterproof glue is used to make marine plywood. so that its wood veneers stay durable for a long time even in water.

4. Hard to identify

It is difficult for a common person (who does not know much about wood and furniture) to determine whether good or bad wood veneer has been used to make plywood.

5. Chemicals 

In the manufacturing of marine plywood, chemicals are used to protect the wood veneer from termites and ants. Which is also harmful to the human’s lungs. 

To avoid its harmful effects, while cutting the plywood, you must wear gloves to your hands and apply eyeglasses. It is very harmful to the patient’s lungs.

6. The edges also need to be covered with wood

The edges of the plywood are very sharp. Small wooden particles start coming out from this edge after some time. These particles may scratch. Therefore, a thin wooden beat is applied to the edges of the plywood.

We know Marine Plywood Advantages And Disadvantages. You can choose another alternative material at the place of the marine plywood which is available in the market. Now let’s see some alternatives.

Alternative to marine grade plywood

Ribbon Grain Plywood, Fiberboard, Fiber Cement Board can be the best Alternative for Marine Plywood.

1. Fiberboard


A Fiberboard is a well-known material that we can use in place of marine plywood. The fiber of wood is mixed with wax to make a fiberboard material. After drying it becomes a solid plywood-like material and is treated with extremely high heat and pressure to make it more durable.

2. Ribbon Grain Plywood

Ribbon Grain Plywood is named because of its grain. It is a sheet of wood with a smooth surface. Because of this, there is no need to spend much on its paint and polish to improve the surface. The installation is also easy.

It is not as strong as marine plywood but it is a good alternative to Marine Plywood.

3. Fiber Cement Board

The Fiber Cement Board is made by mixing cement and wood fibers. The Hatschek process is used to make this board. It is mainly used in Internal / External Walls, Internal Wall linings, False Ceilings, Eaves & Soffit Lining, Facia, and Duct Coverings, Prefabricated Shelters, Roof Tile Underlay, and Flooring Substrate.
