Particle boards are not waterproof; their edges are very porous. The quality of the joinery work on two, or multiple pieces of particle board determines the strength or weakness of the project you are working on.
The constituent particle boards are glued together for the output to become firm. The material, especially the end grains, is crumbly. Screwing the edges together reinforces the joint. A suitable and appropriate glue is necessary so that the two surfaces make a solid bond that stays in place. Therefore, the choice of glue becomes an essential factor for a successful project using a particle board.
Among the crucial features to consider when selecting suitable glue include the type of glue, its visibility, thickness, and drying time. Based on these considerations, standard wood glue, cement glue, and polyurethane super glue are some of the suitable adhesives for joining particle boards together.
Here is How to Glue Particle Board Together
It is a pretty simple process. However, it would be best to distinguish whether you are gluing the boards face to face or edge to face.
PVA Gorilla wood glue is a good choice for a particle board project. Its application is easy as it comes in a squeeze bottle. It has a quick-drying time and blends with the natural color of the board upon drying.
For edge-to-edge Gluing
First, gather the following tools, materials, and equipment:
- Particle boards
- Putty knife
- Gorilla wood glue or adhesive spray
- Wood screws
- Table saw
- Heavy-duty gloves
- Safety glasses
Follow these steps:
- Prepare your workstation and the pieces to be joined. Choose boards with a flat surface. Using a table saw, cut straight edges as they are less trouble when joining. Arrange the boards end to end, based on how you wish to join them. An important tip is to shuffle the pieces until you ensure that the grain patterns at the edges match and look natural. Align the pieces and number them if you assemble several or multiple of them.
- Apply and spread gorilla wood glue smoothly and evenly along the edge of each particle board, using your finger as a guide. Hold the board upright during application for precision as you spread it. Inspect the applied surface properly and add more glue where the layer is too thin or absent.
- Join and press the glued edges together, slide them along, and adjust the surfaces to flush well while ensuring they are neatly and appropriately aligned.
- Clamp the boards together. Apply sufficient clamping pressure by properly tightening until there is squeezed out glue. Remove the excess glue while it is still soft. A chisel or putty knife works. This will save you an extensive task of sanding later. Check for straightness or flatness of the glued boards using a straight edge. To eliminate bows in your glue-up pieces, use shims or add extra clamps. You may add strips of wood between the clamps and the board to protect the edges.
- Remove the clamps after about 20 minutes and allow the joint to dry. Leave the glued pieces in one place and avoid moving them for several hours (at least 24 hours) to allow the glued joint to reach its maximum strength.
For Face-to-face Gluing
It’s done to achieve a greater thickness of the piece. Here is the step-by-step process:
- Cut two separate pieces and trim to ensure the sizes are the same or suit your requirements.
- Apply Gorilla glue evenly on one face of the particle board and use a roller for even spreading, or use adhesive spray on the targeted face.
- Place the two pieces together and line them up correctly.
- Clamp the pieces evenly across both the width and length of the workpieces.
- Allow sufficient time for the pieces to dry. The clamps can then be removed, and the surfaces sanded and polished as deemed necessary.
How to Glue Broken Particle Boards
You will need:
- The broken particle board
- Wood glue
- Glue injector
- Plastic wrap
- Heavy-duty gloves
The tools are easy to use. With its smooth bonding properties and fast-drying aspects, clear Gorilla wood glue will work fine. Here is the procedure to glue a broken particle board:
- Leave the broken piece in place on the particle board.
- Add wood glue to a glue injector and press a thin line of it into the fractured line of the board. If the breakage comprises loose chunks, apply glue to the pieces and on the larger board.
When the applied glue gets tacky, apply pressure to force the broken pieces against the board.
- Use plastic wrap to bind over the broken area and the particle board tightly. It is advisable to avoid using wood as the glue may stick it to the particle board. Place a heavy object, preferably a piece of wood, above the plastic wrap.
- Attach a clamp around the board and wooden block, and screw until it is tight enough to hold the pieces firmly.
- Leave it for about 24 hours for the glue to dry, then remove the clamp and wood. The particle board will be fixed.
Slip-sliding may occur during clamping. To remedy this, you can add salt to the glue for abrasive action or shoot brads into the ends of the pieces. With the appropriate adhesive and the correct procedure, you can smoothly glue particle boards together.
