Using Norton’s Sand Dollar Between Coat Pads versus Screening

Norton Sand Dollars are the new way to sand between coats of floor finish. The patent pending design allows you to smooth and prep the surface of the floor to properly accept the next coat of finish without the risk of nasty swirl marks. There are four different grits: coarse, medium, fine, and very fine to accommodate any application. The foam backing pad allows the product to abrade the surface without penetrating deep into the finish, resulting in a smoother overall floor.
The Sand Dollar has the life and durability of a screen, but leaves a finer scratch pattern. Screens tend to be too aggressive for residential work, especially with newer construction using more windows and recess lights that magnify swirl marks in floor finishes.
The Sand Dollar has grain bonded to a foam backing which allows the grain to glide over high spots in the finish and not impress too deep of a scratch into the finish. This allows it to leave a very fine scratch pattern, much finer than a screen, and at the same time scratching the surface enough to get a good mechanical bond between finish coats.
Some contractors like to use worn screens to abrade finishes. There are multiple problems with this practice. Once the labeling wears off, you don’t know what grit you are using. You also don’t know how worn the screen is, so you wind up with inconsistent abrading, and you may only dull the finish without putting a proper scratch to have a good mechanical bond. The color coding on the Sand Dollar won’t wear off, so a contractor will always know what grit he is using, especially if he is reusing the pad.
The Sand Dollar uses just four different color-coded pads to abrade all finishes, between coats or in recoat applications, greatly simplifying the abrading process. A contractor can keep these four pads in his truck and be able to handle any job situation he may come across.
The Sand Dollar Pad is flexible enough to conform to uneven surfaces, making sure the finish is abraded consistently and evenly. This also minimizes the chance of cutting through the finish on high spots and edges of boards, which is especially importnant on recoat jobs and stained floors. You are more likely to cut through the finish with a screen.
