When it comes to kitchen renovations or installations, square edge worktops have gained immense popularity among homeowners due to their sleek and modern appearance. Joining square edge worktops may seem like an intimidating task, but with the right tools and methods, you can achieve a seamless and professional-looking finish. In this article, we will guide you through the process of joining square edge worktops, ensuring a sturdy and visually appealing result.

What You Will Need

Before you begin, make sure you have gathered all the necessary tools and materials to complete the job. Here’s a list of items you’ll need:

1. Square edge worktops (precisely measured and cut to size)
2. Worktop joining bolts
3. Router or biscuit jointer
4. Clamps
5. PVA woodworking adhesive
6. Pencil and measuring tape
7. Fine-toothed saw or jigsaw
8. Sandpaper (120 or 150 grit)
9. Dust mask and goggles for safety

Step 1: Prepare the Worktops

Start by laying the worktops on a flat surface, ensuring that they are parallel to each other and properly aligned. Measure and mark the locations where the worktops need to be joined, ensuring accuracy for a seamless finish. Use a fine-toothed saw or jigsaw to cut the worktops to the required length, following the marked lines carefully. Remember to wear a dust mask and goggles for safety during the cutting process.

Step 2: Create the Joining Slot

To create a sturdy join, it is crucial to cut a slot into the worktops where they will be joined together. You can achieve this by using a router or biscuit jointer. Measure and mark the position for the joining slot, ensuring you leave sufficient space for the joining bolts. Carefully follow the manufacturer’s instructions for your chosen tool to create a clean and precise slot on both worktops.

Step 3: Sand and Clean the Edges

After cutting the joining slots, use sandpaper with 120 or 150 grit to smooth out any rough edges or imperfections on the worktops. This step is vital for achieving a seamless finish and preventing any visible gaps. Be thorough and ensure that both worktops are smooth, clean, and free from any sawdust or debris. Wipe them down with a clean cloth to remove any remaining dust particles.

Step 4: Apply Woodworking Adhesive

Now that the preparation is complete, it’s time to join the worktops together. Apply a generous amount of PVA woodworking adhesive to the edges of the worktops that will be joined. Spread the adhesive evenly using a brush or spatula, making sure to cover the entire surface. Take care not to apply excessive adhesive, as it may seep out and create a messy joint.

Step 5: Insert Joining Bolts

Once the adhesive is applied, carefully insert the joining bolts into the slots on one of the worktops. Align the second worktop, ensuring the slots and bolts align perfectly. Apply gentle pressure to bring the worktops tightly together, while making sure they stay parallel and level. Use clamps to hold the worktops firmly in place, allowing the adhesive to dry and create a strong bond.

Step 6: Remove Excess Adhesive

After the adhesive has dried as per the manufacturer’s instructions, remove any excess adhesive that may have seeped out from the joint. Use a scraper or a damp cloth to remove the excess while being careful not to damage the surface of the worktops. This step will give your joint a clean and professional look.

Step 7: Sand and Finish

To achieve a seamless finish, lightly sand the jointed area and surrounding edges using a fine-grit sandpaper. This will ensure that the joint is flush with the rest of the worktops and help to blend the surfaces together. Wipe off any remaining dust and debris, and apply an appropriate finishing product or sealant to protect the worktops and enhance their appearance.


Joining square edge worktops may seem like a complex task, but with the right tools, techniques, and attention to detail, you can achieve a professional-looking result. By following the step-by-step guide outlined in this article, you’ll be able to join your square edge worktops seamlessly, creating a stunning and functional centerpiece for your kitchen. Remember to prioritize safety by wearing protective gear and always follow the manufacturer’s instructions for any tools or materials used.
