If you’re new to home renovation, you may be considering what materials to use for your walls. The two main options are plaster and drywall. While plaster has been around for centuries, drywall is the modern go-to option. Drywall is the best choice for most residential projects, and plaster is a better option for luxury construction and historic renovations.
These materials are very different, so learning about them helps you pick the best one for your project. This article will explore the pros and cons of each material, their installation processes, and which one is best for your situation.
Understanding Plaster and Drywall
Plaster and drywall are both popular gypsum-based wall finishing materials, but they have their fair share of differences.
What Is Plaster?
Plaster is a pliable material that applies wet to pre-installed lath to form a flat surface. It has gained a reputation for its durability and ability to create smooth, seamless walls. You’ll typically need professional installation and multiple coats to achieve the desired thickness and finish.
What Is Drywall?
Drywall, also known as gypsum board, is a panel made of gypsum plaster pressed between two thick sheets of paper. It’s pre-formed into sheets, making it quicker and easier to install than traditional plaster. Drywall has become the standard in modern construction due to its cost-effectiveness and ease of use.
Installation Process: Plaster Vs. Drywall
The installation processes for plaster and drywall are very different, which can impact a homeowner’s decision.
Drywall Installation
Drywall installation is generally faster, cheaper, and simpler than plaster. It usually only takes a day or two, depending on the size of the room. This makes it a more time-efficient option for many homeowners.
The process typically involves these steps:
- Cut drywall sheets to fit your wall or ceiling.
- Attach the sheets to studs using screws or nails.
- Tape and mudding the seams between sheets.
- Sand and finish the mudded areas.
Plaster Installation
Plaster installation is a more complex and time-consuming process. Unless you’re experienced with installing plaster walls, you’ll likely need to hire a professional. Additionally, it can take several days to complete, as each coat needs time to dry before adding the next.
Installing plaster requires the following steps:
- Install lath (metal or wood) to create a base for the plaster.
- Apply multiple coats of plaster by hand.
- Allow each coat to dry completely before applying the next.
- Sand and finish the final coat for a smooth surface.
Pros and Cons of Plaster
Plaster offers several advantages and disadvantages that homeowners should consider when deciding between the two.
Advantages of Plaster
Plaster walls have several benefits that make them attractive to some homeowners:
- Durability: Plaster is extremely hard and resistant to dents and damage.
- Sound insulation: The density of plaster provides excellent soundproofing.
- Fire resistance: Plaster is nearly incombustible, offering superior fire protection.
- Customizability: Plaster can be molded into various shapes and textures.
Disadvantages of Plaster
Despite its benefits, plaster also has these drawbacks:
- Cost: Plaster installation is typically more expensive due to labor and material costs.
- Time-consuming installation: The multi-coat process takes longer than drywall installation.
- Difficulty in repairs: Repairing plaster can be challenging and may require professional help.
- Prone to cracking: Over time, plaster may develop cracks due to settling or moisture issues.
Pros and Cons of Drywall
Drywall has its own set of advantages and disadvantages that homeowners should weigh carefully.
Advantages of Drywall
Drywall offers several benefits that have made it the new standard for construction:
- Cost-effective: Drywall is generally less expensive than plaster.
- Quick installation: The process is faster and requires less specialized skill.
- Easy repairs: Homeowners can fix minor damage themselves.
Disadvantages of Drywall
Despite its popularity, drywall does have some drawbacks:
- Less durable: Drywall is more susceptible to dents and holes than plaster.
- Potential for visible seams: If not installed properly, seams between panels may be noticeable.
- Lower sound insulation: Drywall doesn’t block sound as effectively as plaster.
- Less fire-resistant: While fire-resistant options exist, standard drywall is less fire-resistant than plaster.
When To Choose Plaster
While drywall is more common in modern construction, there are situations where plaster might be the better choice. For example, you should use plaster if you’re restoring a historic home, creating custom designs with intricate moldings or textures, doing high-end construction on luxury homes, or if you need more sound insulation in your construction.
Plaster’s durability and customizability make it an excellent choice for homeowners looking for a high-quality, long-lasting wall finish.
When To Choose Drywall
When in doubt, it’s probably safe to use drywall in your home. Drywall is commonly used for new construction projects, budget-conscious renovations, DIY projects, and areas prone to minor damage. Drywall’s versatility and cost-effectiveness make it the practical choice for most homeowners and builders.
Cost Comparison: Plaster Vs. Drywall
The cost difference between plaster and drywall is one of the biggest factors that may sway your choice. Keep the following cost data in mind when choosing which one to use:
Plaster Costs
Plaster installation typically costs more due to higher material costs and a labor-intensive application process. According to Angi, plaster work normally costs between $2 and $10 per square foot. This equals anywhere between $1,200 and $10,000 for an average-sized room.
Drywall Costs
Drywall is generally more affordable because of lower material costs, a quicker installation process, and less specialized labor requirements. According to Angi, drywall installation normally costs between $1.50 and $3 per square foot, which adds up to about $988 to $3,204 for the whole project. However, you can get drywall panels at about $15, not including labor.
Maintenance and Repairs
Installation isn’t the only thing to worry about when it comes to building materials—there’s also maintenance. Keep the following maintenance tips in mind when choosing what material to build with:
Maintaining Plaster Walls
Plaster walls require minimal maintenance, but they can be difficult to repair when damaged. Pay close attention to any cracks or chips so you can prevent them from getting worse over time. For bigger repairs, it’s often best to consult a professional plasterer.
Maintaining Drywall
Drywall is relatively easy to maintain and repair. You can fix small holes and dents yourself with spackle and a bit of sanding. Larger repairs may require patching with a new piece of drywall, but the process is generally straightforward. Fixing drywall is a very common DIY project for homeowners.
Final Thoughts About Plaster Vs. Drywall
While drywall has become the standard in modern construction, plaster still holds a place in high-end and historic renovations. Still, for most homeowners, drywall is the practical choice. It’s affordable and easy to install, making it the perfect combo for DIY homeowners everywhere. Unless you have a special project that you need plaster for, it’s better to go with drywall.
