This handy 45° Angle Block is invaluable for cutting the internal and external 45° angle corners of the Plain Cornice moulding thus ensuring a professional finish. It needs to be used with an electric tile cutting machine with a minimum cutting depth of 75mm, or a carbide tile saw and mitre block (the Cornice moulding sits on top of the angle block, then cut with the carbide tile saw). Please note that, as the angle block is made from Plaster of Paris it is water soluble and likely to only last for one or two installations. Always seek professional advice when using cutting equipment. For more details refer to the Fixing Guide.
