A wood quadrant is a type of moulding with a rounded, quarter-circle profile, often used to cover the joint where two surfaces meet. It’s commonly used in corners where walls meet the floor, ceiling, or around door frames. The curved edge of quadrant moulding adds a decorative touch and helps hide gaps or imperfections in the corner. It’s a versatile trim that works well in traditional and modern interiors.

Quadrant trim covers joints in corners where two surfaces meet, such as where a wall meets the floor or around window and door frames. It can also be used to tidy up transitions between different materials or finishes, providing a clean and polished look. Its rounded shape softens sharp angles and helps give your space a more finished and refined appearance. It’s ideal for creating a neat, professional finish in living areas, bathrooms or hallways.

To fit scotia corners, you'll need to make angled cuts to ensure the trim fits neatly around corners. The easiest way to do this is by using a mitre saw to cut each piece of scotia at a 45° angle at the corner where the two lengths meet. Be sure to measure accurately, as any gaps or misaligned corners will be visible. Once cut, apply adhesive to the back of the scotia and press it firmly into place. For a clean look, use filler to smooth out any gaps before painting or finishing.
