Step-by-Step Guide: Joining Kitchen Worktops with a Mason’s Mitre Joint

Step 1: Measure and Mark

Measure the worktop sections to be joined, ensuring precise measurements and marking with a pencil or masking tape. It is crucial to ensure a snug fit between the sections for a seamless joint.

Step 2: Cut at a 45-degree Angle

Using a circular saw, make a 45-degree angle cut along the marked lines on both worktop sections. Ensure the cuts are straight and accurate for a proper fit.

Step 3: Create Biscuit Slots

Utilise a biscuit joiner to create slots for biscuits on both cut worktop edges. The slots should align perfectly when the sections are joined.

Step 4: Glue and Insert Biscuits

Apply a generous amount of adhesive to the biscuit slots on one of the worktop sections. Insert biscuits into the slots and ensure they are evenly spaced. The biscuits will align the sections for a secure joint.

Step 5: Clamp and Secure

Carefully join the two worktop sections, ensuring the mitre joint aligns precisely. Use bar clamps to secure the sections together tightly. To further ensure alignment, use masking tape across the joint.

Step 6: Final Sanding

Once the adhesive has dried (usually after 24 hours), remove the clamps and masking tape. Use sandpaper to smooth the joint and create a seamless, flush surface.
