If you accidentally sand too much and remove more material than intended, there are a few steps you can take to address the situation: Evaluate the damage: Assess the extent of the excess sanding and determine how it affects the overall appearance of the surface. If it's a minor issue, it might be easily fixable. Fill the gaps: If there are noticeable gaps or indentations due to over-sanding, you can use a suitable filler or spackle to fill them in. Apply the filler, smooth it out, and let it dry. Then, sand the filled area lightly to blend it with the surrounding surface. Feather the edges: If the excess sanding has created an uneven transition between the sanded area and the surrounding surface, you can use fine-grit sandpaper to feather the edges. Gently sand the edges to create a gradual transition, blending the sanded area with the rest of the surface. Repaint or finish: Once you have addressed the over-sanding issue and achieved a more even surface, you may need to repaint or reapply the finish. Make sure to match the colour and texture of the surrounding area to achieve a cohesive appearance.
