Let us start with the simplest type of abrasive, paper-backed abrasive. SurfPrep’s sandpaper is yellow and is a conventional paper-backed abrasive that people are most familiar with. The lower and middle grits are good for sanding and smoothing raw wood for stain or paint prep, and for the removal of some existing finishes. The middle and higher grits are good for sanding veneers in preparation for stain or paint and when sanding between primer or clear coats on flat surfaces. Some of the best prepared surfaces for stain are achieved with SurfPrep’s yellow paper.
SurfPrep’s film abrasives have a durable and thick plastic backing and are faster cutting and longer-lasting than conventional paper-backed abrasives. The abrasive itself is a green/blue color with a white sacrificial stearate coating to prevent clogging. This is a long-lasting abrasive and similar to the conventional paper-backed abrasives, the lower and middle grits are primarily used for sanding and smoothing raw wood in preparation for a stain or a painted finish and for existing finish removal. The middle and higher grits are for sanding veneers for stain or paint prep and for sanding between primer or clear coats on flat surfaces.
Lastly, SurfPrep’s screen abrasives are designed to be a fast-cutting abrasive and because of their design, resistant to clogging. Due to the entire abrasive having small holes, screen abrasives are great for vacuum compatibility. The lower and middle grits are great for fast removal of existing finishes and the middle and higher ones for sanding raw wood, veneers or for between coats of primers or sealers.
