Sanding Dried Joint Compound
At 0:34 in
Home Renovation is an emotion rollercoaster.
What happens here
Once the final coat of joint compound has completely dried and hardened, it needs to be sanded to create a perfectly smooth, seamless surface that is ready for primer and paint. Attach appropriate grit sandpaper to a pole sander. Using smooth, even pressure, sand the areas where compound was applied, working in broad, overlapping strokes across both walls and ceilings. The objective is to blend the joint compound into the surrounding drywall so that no bumps, ridges, or visible lines are present or felt to the touch. The video briefly shows the individual using a pole sander, particularly on higher wall and ceiling areas. It is critically important to wear a dust mask during this process, as sanding drywall compound generates a significant amount of fine dust that can be harmful if inhaled.
Goal: Achieve a smooth, seamless drywall surface ready for priming and painting.
