What Makes 3M a Great Hardwood Flooring Sandpaper

What makes the sandpaper the 3M makes wonderful… is that all of it is mainly the same mineral. This means that you know what you will be getting for a scratch pattern. The Regalite mineral (a special mixture of aluminum ceramic) is great for taking coatings off the floor and lasts incredibly long. Typically this paper on belts does not wear out very fast on belts and can go extremely long. The edger discs are great and usually can rip right through coatings and not be changed out too often. We find that the 3M sandpaper typically works well on all floor finishes and all types of wood. The other great part is, you know it is Regalite if it is purple!

Pros of 3M Sandpaper

  • Long lasting on new floors or older floors with coatings
  • Typically is a good scratch that doesn’t leave too many random scratch marks
  • Same color for all sandpaper so you know what mineral it is
  • Easy to get and is always in stock
