How Does Grit Level Affect Final Deck Finish?

Grit level significantly affects the final deck finish. The grit level of sandpaper indicates the coarseness or fineness of the abrasive material. Low grit levels, such as 60 or 80, create a rough surface by removing material quickly. This roughness helps to eliminate old finishes or imperfections but can leave deep scratches.

In contrast, high grit levels, like 220 or 320, produce a smoother finish. These finer grits polish the wood surface and reduce visible scratches. Achieving a quality final finish often requires a sequence. Start with a low grit to shape and smooth. Progress to medium grit for further smoothing. Finally, use high grit to refine the surface and prepare it for sealing or staining.

Each step builds on the previous one. Using a higher grit before the surface is adequately smoothed does not eliminate deeper scratches. The logical progression ensures that each layer of sanding contributes to an overall polished appearance. The choice of grit thus directly influences how smooth the final deck finish appears.

Which Grit Levels Should Be Used for Initial Sanding?

The recommended grit levels for initial sanding typically range from 36 to 60 grit.
