Frequently Asked Questions
-
Q: What is the advantage of diamond sheets over silicon carbide sandpaper?
A: Diamond sheets last significantly longer than silicon carbide sandpaper on hard materials like stone, glass, and ceramics. Diamond cuts consistently without dulling the way silicon carbide does on hard lapidary materials, providing a lower cost per square inch of material finished over time.
-
Q: Can flexible diamond sheets be used wet or dry?
A: Both wet and dry use are possible, but wet use is recommended for stone, glass, and ceramic applications. Water cools the diamond surface, prevents glazing, and suppresses dust. For metal applications, a light cutting oil often produces better results than water.
-
Q: What backing option should I choose?
A: Choose PSA backing for flat lap machines and sanding blocks. Choose hook-and-loop for orbital sanders and quick-change sanding systems. Choose plain canvas for hand sanding and custom mounting applications.
