A cove mitre is a tool used to provide an accurate guide for cutting the corner joint angles known as mitres (see below) on coving.
What is a mitre?
A mitre joint is an angled joint between two pieces of material. They are often used on corners.
A mitre joint can be used to join two pieces of material together at any angle. The angle of the mitre cut on the two pieces of material being joined is always half the total angle of the corner you want to achieve, so a 90 degree corner has a 45 degree mitre cut on the two adjoining pieces of material.
What is coving?
Coving, or cornice to give it the correct name, is a decorative mould fitted along the top of a room where the walls and ceiling meet. Originally used to hide cracks or gaps between the wall and ceiling, now the main purpose of coving is decoration.
Cornice can be made of several materials including wood, polystyrene, paper-coated plaster and high-density polyurethane.
What is the difference between coving and other types of cornice?
Coving is a plain, concave ‘C’-shaped style of cornice that has become so popular that the term coving is now often used to describe all cornice styles.
A concave shape is one that curves inwards. It is the opposite of a convex shape.
Cornice usually has more intricate and ornate patterns than plain coving and is often fitted in period properties.
