How Much Does Plastering Cost? [2025 Data]

Plastering walls costs anywhere between $1,200 and $10,000 for an average-sized room, with most homeowners spending $5,000. The cost largely depends on the size of the space—around $2 to $10 per square foot—and whether you’re also plastering the ceiling. 

Plaster is a common material used for interior finishing. Traditionally, plaster smoothes the surface—or creates a texture—to form an even look before painting. Some homeowners prefer the vintage look of textured plaster and like to leave it as a finish on its own.

Cost of Plastering per Square Foot

The table below illustrates the plastering wall cost by the size of the area. You can estimate the cost of the project using the square footage.

Plasterwork usually costs between $2 and $10 per square foot. 

The cost depends on whether you want resurfacing work or not. Expect to pay at least $10 per square foot with resurfacing; otherwise, plastering a wall usually costs between $2 and $5 per square foot.

Plastering Cost Factors

Several variables affect the cost of plaster application, including application materials, plaster type, and labor.

Materials

The material to apply plaster costs between $2 to $10 per square foot. 

Plaster materials are relatively inexpensive. A 5-gallon bucket of lime plaster costs around $60, while a 25-pound bag of plaster used for decorative plaster costs $10 to $30. However, some luxury types of plaster might cost up to $400 or more for a 5-gallon bucket.

Labor

Expect to pay labor costs between $2 and $5 per square foot to apply plaster or $4 to $10 per square foot for refinishing, which requires more work to prep and remove existing plaster. The average cost to plaster a room of four 10-by-10-foot walls can run from $800 to $4,000.

The average cost to plaster a ceiling is about $600, although you could pay as little as $400. If the ceiling is taller than average, you’ll pay $800 or more. If you want ornamental designs or the ceiling has a vaulted shape, you could pay up to $4,000 for the entire job.

Plaster repair contractors charge by the hour, so when hiring, expect to pay $60 to $80 per hour.

Skim Coat Plastering 

The cost to skim coat a wall is between $1.10 to $1.30 per square foot.

Skim coating is a type of plastering that involves applying a couple of thin layers of plaster to create a smoother finish or to repair a surface. Skim coating allows for a new look on your walls and can be less time-consuming and expensive than redoing drywall. 

Texturing

Adding any special texture may cost an extra $1 to $3 per square foot. One of the greatest things about choosing plaster is the ability to add designs and texture, creating unique and interesting walls. There are many different ways to make texture, such as the dash, lace, and stucco plasters, which vary in difficulty and require professional and artistic skills. 

Finishes on a plaster wall can change the entire feel of a room. They often give a home a particular style—like pebble dash, which can be great for a beach house—or sand or cement finishes to provide a more rustic feel.

Prepping and Repairing Existing Plaster

Budget an extra 10% to 30% for prep work, which ranges from $1 to $3 per square foot. Prepping the wall is an essential part of plastering and costs extra, depending on the condition of the surface. During prep, a plaster contractor fills holes in the wall, applies a primer, and sands the surfaces.

“When we restore a historic home, we have a lot of plaster repair,” says Bob Tschudi, Expert Review Board Member and Raleigh, N.C.-based general contractor. “A lot of the work is repairing the wood lath strips behind the plaster. Without this prep work, the new plaster will probably crack in a short period of time.”

Ceilings vs. Walls 

Plastering walls costs less than plastering ceilings because ceilings are less accessible. Expect to spend $0.50 to $2.00 more per square foot to plaster your ceiling. Most homeowners spend between $390 and $900, depending on the height of the ceiling. The price will significantly increase if you add ornamental designs or have an unusual ceiling shape.

Asbestos or Lead Paint Removal 

You’ll commonly find plaster walls in older homes since most modern homes use plasterboard (or drywall) of varying sizes. Unfortunately, this increases the chance of asbestos contamination and lead paint. Plaster products made between 1920 and 1970 contain asbestos, and lead paint is common in homes built before 1978. 

Here's how much you can expect to spend if you need to remove asbestos or lead paint before plastering your walls.

Cost of Different Types of Plaster

When you hire a pro, the cost of materials for nearly all types of plaster is between $10 and $15 per square foot. Each type delivers slightly different benefits and will work for a wall or ceiling. 

Fortunately, because each type has similar costs, you can select a plaster type based on the project's needs rather than settling for an option that fits your budget.

Gypsum

Gypsum plaster consists of soft sulfate materials. It’s a good material to use over rough materials like brick and plasterboard. When you want to create a smooth finish for painting, gypsum plaster is an ideal choice.

It is less likely to shrink and crack than some of the other types of plaster. It’s the most common type of plaster in use and has one of the lowest prices.

Venetian

You might know Venetian plaster as lime plaster. It consists of limestone, sand, and water, but some manufacturers add fibers to it to make it bind tightly. Depending on the formula in use, the cost of Venetian plaster can range from a wallet-friendly option to one of the most expensive options.

It’s one of the oldest types of plaster formulas, providing a soft appearance when it dries, which results in a pleasing appearance. 

Cement

Cement plaster works as an outdoor type of plaster consisting of cement, sand, and water. It often goes directly over masonry, concrete, or metal lath. It has a low initial cost. However, it can require multiple coats, which can increase the price of outdoor plastering.

It isn’t suitable for painting because it doesn’t create a perfectly smooth surface. If you want to paint it, you might place a layer of gypsum plaster over cement plaster.

Acoustic

Acoustic plaster is one of the more expensive types of plaster and uses a special formula to provide sound absorption. It consists of gypsum plaster mixed with fibers designed to absorb sound. An installer often will apply it in layers to improve performance. 

In addition to sound dampening, newer formulas deliver impressive aesthetic designs resembling marble or stone. This makes it ideal for a home recording studio, but it also often appears in museums or commercial buildings that need perfect acoustics and a high-end look.

Tadelakt

You might know Tadelakt plaster as Moroccan plaster. It uses lime as the base, but its formula provides waterproof capabilities, allowing for its use in bathrooms and kitchens.

It is an expensive plaster, but it has an impressive look when it dries. Its rustic finish is hard to duplicate with other plaster types. You can often select from multiple colors with Tadelakt plaster.

Why You Should Hire a Plaster Repair Pro

Hiring a local plaster repair pro costs $4 to $10 per square foot for labor. Although the job may seem doable for a homeowner, it’s more challenging than it might seem and requires specialized tools. For these reasons, it’s best to hand this project off to the pros.

Here’s why it’s ideal to hire a plaster installer

Here are the benefits of hiring a plaster installer:

• Plaster repair pros have specialized tools to install plaster walls, which are costly to purchase for a one-time DIY job.

• Plastering requires skill, and hiring a pro ensures that your walls are free of common DIY issues, such as cracks and bumps.

• A plaster repair contractor will get the job done right the first time, whereas a DIYer may struggle to learn the technique.

• You’ll have the option of adding custom accents, such as crown molding and trim, to elevate the ambiance of your home.

• Plaster installers follow safety protocols during prep and installation and can accurately identify asbestos and lead paint.

• You’ll have the option to choose every type of plaster when hiring a professional.

• Your plastering pro will be able to repair different types of lath before the installation. 

If you want to DIY plaster walls

If you want to tackle some of your plaster projects on your own, consider some of these smaller tasks: 

• Sealing the plaster

• Painting the walls after installation 

• Small plaster repairs 

Cost of Common Wall Plastering Add-Ons

In addition to finishing touches like texturing the plaster, there are some common add-ons to consider: 

• Sealing plaster: The job isn’t completely finished after applying the plaster. You can seal the plaster to ensure better paint application and prevent inconsistencies in the final appearance for about $1 per square foot.

• Painting walls: Once the plaster is installed, sealed, and fully dry, you’ll need to paint the wall to finish the job. Painting walls costs between $1 and $3 per square foot, depending on whether you do it yourself or have a painter do it for you. While doing the painting yourself will cost less, it will also take longer than if a professional does it. 

• Decorative plastering: To achieve a more elevated look, you can add decorative plastering to act as crown or cornice molding. This adds around $1.50 per square foot to the project, but it can cost more, depending on the level of detail.
