First of all, you need to know what plywood is. It is a material made from several layers of a natural wood slice which is about 1 mm thick. These layers are arranged perpendicular to the wood grain orientation of each layer. Then they are pressed together under high temperature and pressure with the involvement of adhesives. How to glue plywood together? Find out the following information.
How to glue plywood together?
Gluing sheets of wood are to increase cohesion while reducing the separation between layers when we nail on the edges. Another benefit is reducing expansion and shrinks of the plywood, increasing durability and structural stability of the plywood.
That is why plywood is very different from natural wood. They are not susceptible to shrinkage, termite or cracking due to different weather and use conditions. Plywood is widely used in construction, yarns: wall, ceiling, formwork, packing…etc.

Due to the arrangement of laminated wood, the plywood is very hard and has very high mechanical strength. Thus, gluing two pieces of woods together to make a thick piece is a good method for many people. Refer to the following steps to know how to glue plywood together:
Use a flux brush to apply glue
You can prepare flux brushes in hardware stores and household appliance shop. It can help you apply and evenly spread glue onto the wood pieces. For complicated joints indoor rails, these brushes work very well; even you can merge it in water and use again in several times.
Use a Wax paper to prevent spots of marks
When you contact with clamps to contact with wood flue, place a wax paper sheet to prevent leaving a dark spot when you glue the edge of the plywood.
Rub the Join
This method ensures that the surface of the joints can be effectively attached together by polishing their edges and spreading the glue more evenly. It can also manage defects and small holes in the surface. When rubbing the joint is carried out exactly, it will ensure:
- Ensure the smooth surface, clean every corner of the product
- Ensure the exact thickness and flatness
- Cost less time for surface treatment
- Smoothen thoroughly in the details of the carving.
Finish each board of several sheets of plywood at a time
We all know that each plywood sheet is very thin. Gluing several sheets of plywood together is to make it thicker. It’s better for us to get all done at a time to ensure the top surfaces in a board aligned. Finish each board for about 20 to 30 minutes before moving into the next board.
We can screw two pieces of plywood together at joints and hide screw inside the piece of wood. If you want to know how to hide screw in wood to make its surface more perfect, read more at the article: “How To Hide Screws In Wood In Just Minutes”.
Use a type of superglue to attached small pieces together
The adhesive which is usually used in the production of plywood is Phenol Formaldehyde. Besides, there are many types of glues in the store or shops.
However, superglue like cyanoacrylate can glue marine plywood together which may be hard to be clamped. One more benefit is that it doesn’t make a mess by running off along the wood even when we glue edges of the plywood.
Please note when using super glue:
- It is suitable to use on the surface of wood, plastic, metal, after when these materials are treated with the surface preparation
- Before gluing, clean dust, oil, and other dirt
- Keep out of the reach of children because of its chemical compound.
- Store and use in cool place, avoid sparks or flames
Use an abrasive pad to remove excess amounts of glue
No matter how skilled you are, when glue is dried, there are some remaining light spots. Abrasive pad is a kind of material that is used to abrade the surface of products made of metal, wood, plastic, glass…to create a surface of the product.

You can soak an abrasive pad into the water to polish these spots with an abrasive pad. Scrubbing it off to remove excess flue and when the surface is dry, you can use a rag to clean.
Note: When using abrasive paper to polish, users should have the following notes to ensure safety and polish quality:
- If you handle manually, you should use protective clothing such as gloves, dustproof glasses, and masks. This helps protect you from dust and dirt from wood surfaces that cling to the body and cause damage.
- If you use abrasive pads by machine, make sure that the joints of the machine are tight enough so that the parts are not splashed out to cause injury to health and life.
Finally, use tape to control glue after finishing
Before you let the glued sheets of plywood dry itself, you can use a tape surrounding its surface to prevent it squeeze-out. Gluing laminating plywood might be ended at this step. If you’re wondering how long it shall dry, please read more at how long for wood glue to dry?.
The structural characteristics of the plywood surface are thin and smooth. Its inner core is much thicker than the surface. Consequently, it will enhance the cohesion of the surface layers, which are directly under the highest external impact. With external forces, the outer layer absorbs most of the impact, and the impact on the core is nearly zero. Today, plywood is widely used because of its remarkable features such as low price, high durability.
When we screw or glue two pieces of plywood together, its structure shall be strengthened and thicker. When we apply a force to the plywood, the structure makes the outer layers more difficult to tear, so the plywood sheets have the better appearance.
Therefore, it’s vital for us to understand the characteristics of plywood and know how to glue plywood together to enhance its durance and appearance. Compared with natural wood, plywood is much cheaper. In the current situation of climate change, the use of industrial wood is an essential solution. So, let’s change our consumption habits to protect the environment.
