ā Wet/Dry Triangular Sandpaper ā Common Questions
š¹ Which grit should I start with for removing old paint or varnish?
For stripping or leveling, begin with 300 or 600 grit (dry). These coarser sponges quickly cut through layers without premature loading. Then progress through 800, 1000, and 1200 to erase scratches before moving to wet sanding with finer grits.
š¹ Can I use these triangular sanding sponges wet without ruining them?
Absolutely. The sponge core is closedācell and waterāresistant. Wet sanding with a few drops of water or a mild lubricant (especially recommended for grits 1500ā3000) reduces dust, prevents clogging, and produces a smoother surface on automotive clear coats, metals, and painted surfaces.
š¹ How long does one sponge last, and are they washable?
Longevity depends on pressure and material. The abrasive is bonded to a durable foam base. You can rinse them multiple times to restore cutting power. When the abrasive eventually wears smooth (typically after several projects), simply replace it with the next grit in the pack. Theyāre reusable far longer than standard paper sheets.
š¹ What makes the triangular shape better than square or round pads?
The 60Ā° pointed corners access inside corners of furniture, window mullions, and detailed trim where rectangular blocks canāt reach. You get three sharp edges per sponge, so you can rotate for even wear. Plus, the 80mm size is perfect for oneāhanded control in tight spaces.
