❓ Frequently Asked Questions – Triangular Sanding Discs

Q: What sizes do these triangular discs come in, and which one fits my tool?

A: You’ll receive both 80mm (3.15″) and 90mm (3.54″) triangles in the pack. To verify fit, simply measure the side length of your sander’s backing pad. If it matches either dimension, the hook‑and‑loop surface will grip instantly. Most name‑brand detail sanders and oscillator attachments accept one of these two sizes.

Q: Are these discs suitable for wet sanding, and does the sponge hold up?

A: Absolutely. The foam core is closed‑cell and bonded with waterproof resin, so it won’t soak up water or turn mushy. Using them wet dramatically reduces airborne dust and gives you a finer, swirl‑free surface — perfect for automotive clear coats, gel coat, and high‑gloss finishes.

Q: What does “300#–3000#” mean, and which grit should I start with?

A: The range covers medium‑coarse (300#) all the way to micro‑fine (3000#). Start with a coarse grit like 300–600 if you’re removing material, shaping, or stripping paint. Progress through 800–1500 for smooth prep, and finish with 2000–3000 for a polished, glass‑like shine. The assortment gives you every step in one package.

Q: Will the hook‑and‑loop backing hold up under heavy pressure?

A: Yes. The loop fabric is tightly fused to the sponge, and the hooks bite firmly into your sander’s pad. Even when pressing into corners or sanding over edges, the disc stays flat and aligned. To maximize life, keep your sander pad clean and remove discs after use instead of leaving them attached for days.

Q: How many discs are included, and are they reusable?

A: Each bundle provides a generous assortment across the 300–3000 grit range (roughly 10–15 discs depending on the selection). Thanks to the high‑quality grain and clog‑resistant coating, each disc can be used multiple times. For dry sanding, a quick brush or rubber cleaning stick restores the grit instantly.
