Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

There are several benefits to wet-sanding drywall, but the main perk is that it produces far less dust than dry-sanding. As a result, wet-sanding poses fewer health risks and makes less of a mess in your home. Plus, damp sponges are less abrasive than sandpaper, so there’s a smaller chance of scratching or damaging the drywall paper. Wet-sanding also creates a smoother finish than dry-sanding.

Most handy homeowners can tackle removing texture from unpainted walls. Removing texture from painted walls is a bit trickier. Paint acts as a sealant, so you can’t soften the texture with water. Instead, you’ll have to add a layer of drywall compound known as a skim coat. This process is messy and takes some practice.

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.
