Coving field material
When it's installed in a wet area, such as a shower or bathroom, the coving height must be at least 150 mm.
Depending on the radius of the curve at the base, a heat gun may be used to make the floor covering more flexible, particularly at corners.
Internal and external 'butterfly' corners
AS 1884 does not permit vertical welds in the corners of coved sheets in wet areas.
This is because the weld could become a weak point if there is any movement in the substrate, which would reduce the corner's water resistance.
Instead, the joints must be cut at 45 degrees to the corner.
Mitred corners using a 'make-out' piece
In areas where water resistance is not a priority, it's possible to mitre the corners with the aid of a separate make-out piece.
However, the end result is a corner with a vertical join, so you must make sure that it will be acceptable in the project you're working on before you decide to finish the corner in this way.
