Silverline 1/3 Sheet 240 Grit Sandpaper – Key FAQs

• What is 240 grit best used for on a 1/3 sheet sander?
  240 grit is ideal for fine finishing preparation and sanding between coats, helping smooth the surface and improve adhesion without leaving deep scratch marks.

• Will these sheets fit my clamp/clip sander?
  They are pre-cut for 1/3 sheet sanders that take 93mm x 190mm clamp/clip papers. Check your sander pad size to confirm compatibility.

• What does “open coat” mean on sandpaper?
  Open coat abrasives have more space between grains, helping dust clear more easily. This reduces clogging and can extend the usable life of the sheet.

• Can I use these sheets for hand sanding?
  Yes. They can be used on sanding blocks or folded for hand sanding, especially for final preparation and smoothing work.

• How can I make the sheets last longer?
  Use light pressure, clear dust frequently and consider an abrasive cleaning block to remove clogged debris and keep the abrasive cutting effectively.

• Should I use a coarser grit before 240 grit?
  Usually, yes. Start with a coarser grit if you need more removal, then progress to finer grits and finish with 240 grit for a smoother surface.
