Cutting Mitered Corners for Optimal Fit

What happens here

When cutting mitered corners for composite trim or decking, a precise 45-degree cut is essential for exterior edges that will be highly visible. For interior corners, a slight 'overcut' (e.g., 46 degrees) can be beneficial. This creates a tiny gap at the back of the joint, ensuring the visible front edge remains tightly closed and seamless. Use a miter saw for accurate cuts.
