Terms of the Trade: What Is Wet Sanding?

To limit the amount of dust that usually occurs when sanding drywall joints, use the wet sanding method. Purchase a large flat drywall sponge, wet it, and wring it out. Wipe smooth any flaws on the drywall and the mud. You'll find that the wet sponge will collect some of the dust, making this project less messy than it otherwise would be. Unless you have really uneven areas, you probably won't need to use the rough side of the sponge.
