Prepare Surface by Sanding

What happens here

Begin by thoroughly sanding the wood surface that you intend to fill and paint. Use an orbital sander equipped with a dust collection system to minimize airborne dust. The initial sanding removes any existing finish, smooths out minor imperfections, and most importantly, opens up the wood grain, allowing the grain filler to penetrate and adhere effectively. Sand all flat surfaces and edges evenly.

Goal: Create a clean, smooth, and receptive surface for grain filler application.
