Indasa 5" PSA Discs for Secure, Economical Production Sanding

Short answer: Indasa Rhynostick White Line 5-inch PSA discs combine a fast-cutting aluminum oxide abrasive with a pressure-sensitive adhesive backing that holds firmly to a compatible stick-on pad. They are a practical everyday choice for boat repair, fiberglass work, fairing, paint preparation, composite fabrication, automotive refinishing and woodworking.

General Grit Selection Guide

This chart is a general starting point. Always follow the primer, paint, gelcoat or coating manufacturer’s required sanding schedule.

Fit and Attachment

Use these discs on a clean 5-inch PSA/stick-on backing pad. Peel the protective release paper, center the disc and press it firmly across the pad face. Remove dust and old adhesive from the pad before installing a new disc. The solid face does not provide through-disc dust extraction.

PSA or Hook & Loop?

Choose PSA when you want a firm adhesive connection for longer sanding runs. Choose 5-inch Indasa Rhynogrip hook-and-loop discs when fast grit changes and easy disc removal matter more.

Frequently Asked Questions

How many PSA discs are in a box?

P40 and P60 contain 50 discs per box. P80 through P600 contain 100 discs per box. The selected grit should always display its package quantity beside the option.

What does PSA mean?

PSA means pressure-sensitive adhesive. Peel away the protective release paper and press the disc onto a clean, compatible stick-on backing pad.

Can I attach these to a hook-and-loop pad?

No. These discs require a PSA/stick-on pad or a properly installed PSA conversion surface. For a standard grip pad, choose the Rhynogrip hook-and-loop version.

Can I use these discs for wet sanding?

No. Rhynostick White Line is designed for dry sanding. Choose an abrasive specifically rated for wet use when water is part of the sanding process.

Do these discs work with dust extraction?

This listing is for solid discs without extraction holes. Use a perforated disc whose hole pattern matches the backing pad when through-disc extraction is required.
