Homeowners and contractors frequently utilize plaster to cover building walls, resulting in a polished surface ready for painting. This is a widely practiced method for completing interior walls and ceilings, and is a prevalent form of interior design. The cost of plastering is reliant on the choices made and the dimensions of the area. For extensive and elaborately decorated walls, the average cost for plastering can be fifty percent higher than standard rates.

Professionals charge between $4.50 and $14 per square foot to plaster a wall. Plastering a standard 16 X 20 feet living room (320 square feet) costs $1,440 to $4,480, excluding the ceiling. In contrast, the cost to plaster an average-sized bedroom measuring 11x 12 feet (132 square feet) ranges from $594 – $1,848 minus the ceiling. Prices are determined by wall size and type, types of plaster material, equipment required, and work difficulty.

Although homeowners can DIY plaster walls, plastering requires high-level skills and experience. Thus it is imperative to hire a professional. You can search nearby plasterers online for an estimate.

The national average to plaster walls is $4.5 and $14.00 depending on the wall condition, height, access and plaster material. 

Re-plastering a wall costs significantly more than applying fresh plaster due to removal costs of the old plaster and preparation and finishing work involved.

Cost to plaster by room size

Homeowners should understand that it costs more per square foot to plaster a room or two than plastering an entire house. Also, certain rooms in the house, like kitchens and bathrooms, require more expensive heat-resistance or water-proof plaster types, which may increase the project cost for those rooms over others.

Attics, crawl space, basements, and garages may require different finishes due to the wall types and moisture issues. Also, the job complexity when working in these areas can increase labor costs.

Below is a table showing the cost to plaster each room within a 1,500 square feet home. The prices below are inclusive of labor.
