SOP - White Wood Finishing
Proper White Wood Sanding ensures that the finish being applied will have good adhesion, uniform stain color and the desired look intended for the finished part. The following guide is designed as a starting point for sanding procedure. Final grit selection may be changed to meet specific application requirements.
Identify the type of wood you will be sanding. Harder species of wood require a more aggressive (coarse) grit. Softer ones, a less aggressive grit to achieve the same result.

Refine the scratches from the using the next finer grit of the abrasive. Always graduate one grit step at a time. (P120-P150-P180-P240)
Repeat the sanding steps until the surface has a smooth, uniform finish with the grit specified by the sealer manufacturer.

Complete the sanding steps until the surface has a smooth, uniform finish with a P240 grit abrasive.
Lightly sand the edges of the part. The sanding process has created sharp edges. Smoothing or "easing" these edges will allow the finish to maintain a uniform film thickness for proper adhesion and appearance.
