FAQ
What is the difference between sanding sponges and sandpaper?
Sanding sponges have a foam backing that conforms to curved surfaces and maintains shape. They are reusable, washable, and easier to grip than loose sandpaper. Sandpaper is thinner, more flexible for wrapping around blocks, and cheaper for large flat areas but tears easily and does not conform to contours.
Can these sponges be used wet for automotive sanding?
Yes, the LD-189 sponges are suitable for wet sanding when used with water as a lubricant. Wet sanding reduces dust, prevents clogging, and produces a finer finish ideal for automotive primer and clear coat preparation. Rinse and allow to dry completely before storage.
How do I clean a sanding sponge to extend its life?
Tap the sponge against a hard surface to dislodge dust, or rinse under water for wet-compatible applications. Avoid using compressed air as it can damage the foam structure. Replace the sponge when the abrasive surface becomes smooth or the foam loses its resilience.
Which grit should I use for different stages of finishing?
Use 60-80 grit for aggressive material removal and rough shaping. Use 100-120 grit for general smoothing and removing scratches from coarser grits. Use 150-180 grit for final preparation before staining or priming. Use 220 grit for between-coat sanding of paint and varnish.
