1. Smoothing the Surface
Sanding helps to smooth out any rough or uneven areas on the surface of the PVC foam board. It removes small imperfections, bumps, or texture irregularities, creating a more even and consistent surface.
2. Improving Adhesion
Sanding the surface of PVC foam board creates a slightly roughened texture, which improves the adhesion of adhesives, paints, or coatings that may be applied to the board. This enhanced adhesion ensures better bonding and durability of the applied materials.
3. Enhancing Paint Finish
Sanding the surface of PVC foam board provides better paint adhesion and promotes a smoother finish. It helps to create a surface that allows paint to adhere more effectively, reducing the risk of peeling, flaking, or uneven coverage.
4. Removing Gloss
PVC foam board often has a smooth, glossy surface, which may not be desirable for certain applications. Sanding helps to reduce the gloss and create a matte or semi-matte finish, providing a more aesthetic and suitable surface for specific uses.
