Frequently Asked Questions
What types of materials can these delta sanding sheets be used on?
These 40 grit aluminum-oxide sheets are suitable for sanding all types of woods, chipboard, plywood, and construction boards. They are specifically designed for pre-sanding rough, uneven beams and boards where aggressive material removal is required.
Why are the sanding sheets perforated?
The perforated design allows dust to be extracted through the sanding pad during use. This helps keep the work surface cleaner and reduces the buildup of debris on the abrasive face, supporting a more consistent sanding result.
Is 40 grit the right choice for my project?
40 grit is a coarse abrasive level best suited for pre-sanding and aggressive stock removal on rough or uneven surfaces. If your project requires smoothing or finishing, a finer grit sheet would be more appropriate for those later stages.
