i. Arrangement of Boards:
The most crucial part of joining boards is to arrange and mark the boards. Lay down the boards on a clean surface. Now adjust them side by side keeping them per the correct pattern and shades. After alignment, draw any sign or a U with the help of a chalk marker. The mark will help you track the correct points to be joined after the glue is applied.
ii. Adhesive Application:
After the alignment is done, now is the time to apply the glow or any sticky material you have selected for the procedure. Pick up one of the boards and apply the glue on the entire side of the board. Make sure you do justice with the amount of glue. It should not be less or more than the requirement otherwise it will affect the firmness.
iii. Clamping The boards:
Now slide the board back carefully following the chalk guides. Once you’re satisfied with the alignment, clamp the boards together by exerting some force. The clamping would help the glue to spread evenly. Let it stay over there for almost half an hour. This step will let the glue dry off to bind the two wood planks.
iv. Rinse off the extra glue:
The final step of the process is to clean the extra glue spilling out of the boards. This will give the boards a clean attached look. And if you leave the glue uncleaned, it will affect the finishing.
Pros and Cons of this method
This is the cheapest and easiest method among the rest of the joining board’s methods. You don’t require some special kind of tools or expertise to do this. All you need to be cautious of is the correct alignment and enough amount of glue applied.

i. Measurement of the wood boards:
Lay down the wood boards on a clean surface. Measure the width of the board and adjust the depth collar of the drill according to that. This will ensure accuracy in the measurement of the pocket hole. Then lift the precise guide hole relative to the pocket hole.
ii. Wood Clamping and Drilling:
The next step is the wood board clamping. Then start drilling into the guide holes keeping in view the alignment of the planks. You can drill two to three sets of pocket holes to attain maximum firmness.
ii. Finishing of Joints:
The final step is to join the boards. Put the drilled one aligned to the other one and start drilling and inserting screws. Keep on drilling until you reach the second wood and flush inside the pocket hole.

- Cordless drill
- Drill bits
- Ruler and Pencil
- Ready-made dowels
Sequential Guide On Dowels Method
i. Identify Dowel Spots:
Start by measuring them and pointing out the spots where you want to fix the dowels. Pre-mark the points at an equal distance using the pencil and ruler. While marking the points, consider the depth and length of your planks and do the job precisely. Even a minor mistake can affect the accuracy of the work.
ii. Start the drilling work:
Take a drill test first to check if you do it right. Make sure you choose the diameter of your drill bit accurately as per your dowel. Then mark the drill bit at half of the length of your dowel’s length. Start drilling the hole and try to fit in the dowel when the drilling is done.

- Biscuit jointer
- Measuring tape
- Spray water bottle
Sequential Guide On Biscuit Joining Method
