PROBLEM TO BE SOLVED: To provide a substrate corner material of which a volume is reduced only a little, even when a putty material is dried sufficiently after being smoothed using a putty spatula.SOLUTION: A substrate corner material is a long material disposed along an intersecting line at an internal corner or an external corner where two wall surfaces with a finishing material intersect, and includes a bent part along a central part of the long substrate corner material in a longer-side direction, a pair of flat plate parts formed on both sides of the central part, and a plurality of open holes through front and rear surfaces of the pair of flat plates. All of the plurality of open holes are long holes with a greatest length along the longer-side direction of the long substrate corner material greater than a greatest width in a direction orthogonal to the longer-side direction.SELECTED DRAWING: Figure 2 |
