What is Plaster?
Plaster is one of the oldest wall finishing materials, with a history that dates back centuries. The primary method for finishing interior walls before the mid-20th century, especially in homes built before 1950, was plaster.
Plaster is a mixture of cement, sand, water, and sometimes gypsum or granite. People use it for its strength and texture. You apply this mixture in layers over a lath or plasterboard, which serves as a base. Once each layer dries, it forms a dense, hard surface that can be smoothed, textured, or painted to achieve the desired finish.
Advantages of Plaster:
Durability:
Plaster is incredibly durable. When properly applied, it forms a solid, dense surface that can last for many decades without showing signs of wear. Less prone to dents, dings, and cracks compared to drywall.
Fire Resistance:
One of plaster’s standout qualities is its natural fire resistance. The gypsum in plaster contains water, which helps slow down the spread of fire, making it a safer choice for homes and buildings.
Soundproofing:
Plaster’s density makes it an excellent sound insulator. It reduces noise well, so it’s great for apartments or homes with multiple families where reducing sound is important.
Aesthetic Appeal:
Plaster offers a wide range of finishes, from smooth, polished surfaces to intricate textures like stucco. It also works well on curved surfaces and complex architectural details, where drywall may struggle.
Challenges of Plaster:
Cost:
The installation of plaster is labor-intensive and requires specialized skills, which makes it more expensive than drywall. Costs can range from $2 to $10 per square foot, depending on the complexity of the job and the region.
Time-Consuming Installation:
Plaster installation involves several steps. You must carefully apply each layer and allow it to dry before adding the next one. This can extend the construction timeline significantly, sometimes taking weeks to complete.
Difficult Repairs:
Although plaster is durable, it can be challenging to repair if damaged. You can fix small cracks with plaster kits, but significant cracks or water damage require a professional’s help.
What is Drywall?
Drywall, also known as gypsum board, became popular for interior walls in the mid-1900s. It is easy to use and affordable.
Workers sandwich a layer of gypsum plaster between two thick sheets of paper to make drywall. Workers cut the sheets to size and install them using nails, screws, or special drywall fasteners. Because drywall is easy to cut and install, it quickly became the preferred choice for contractors and DIYers alike.
Advantages of Drywall:
Cost-Effective:
Drywall is much cheaper to install than plaster, with costs typically ranging from $1.50 to $4 per square foot. This makes it a budget-friendly option for both residential and commercial projects.
Quick Installation:
Drywall sheets come in standard sizes, which allows for rapid installation. A skilled crew can finish installing drywall in an entire house in just a few days, making it ideal for projects on tight schedules.
Ease of Repair:
Unlike plaster, drywall is relatively easy to repair, and the drywall repair cost is generally more affordable. You can easily fix small holes and cracks with a repair kit, and replace damaged drywall sections without much trouble.
Insulation Friendly:
The space behind drywall panels makes it easy to add insulation, which is crucial for energy efficiency. You can easily install fiberglass batts, spray foam, or loose-fill cellulose to enhance the building’s thermal performance.
Challenges of Drywall:
Lower Durability:
Drywall is less durable than plaster and can be easily damaged by impacts or moisture. Over time, it may develop cracks, holes, or bulges, especially in high-traffic areas.
Poor Soundproofing:
Standard drywall does not block sound as effectively as plaster. Adding insulation or acoustic drywall can help reduce noise. However, they are not as effective as plaster for soundproofing. Plaster is better at naturally reducing noise.
Moisture Vulnerability:
Drywall is susceptible to water damage, which can lead to mold growth if not addressed promptly. Special moisture-resistant drywall is available, but it’s generally more expensive and not as widely used.

Plaster vs. Drywall : Detailed Comparison
Cost Considerations:
If you’re on a tight budget, drywall is likely the better option. The lower material and labor costs make it an affordable choice for most projects. Plaster, while offering superior durability and aesthetics, requires a greater investment both money and time.
Consider the costs and long-term benefits. Plaster might cost more initially, but its durability could make it a better value in the long run.
Durability and Longevity:
Plaster is the clear winner in terms of durability. Once properly installed, it forms a rock-hard surface that can stand up to daily wear and tear for decades.
Drywall, on the other hand, is more prone to damage from impacts and moisture. Drywall is easier to fix, but it needs repairs often. Plaster may be a better option for those wanting something that lasts longer and requires fewer fixes.
Installation Time and Process:
Drywall is far easier and quicker to install. Its pre-cut panels are designed for fast installation, making it a popular choice for large-scale projects or those with tight deadlines.
Plaster installation is a more involved process that requires layering and careful drying. Longer timelines can be a problem for time-sensitive projects. However, the higher quality and durability of plaster often make the wait worth it.
Soundproofing Capabilities:
Plaster’s dense structure makes it an excellent sound barrier. If you’re making a home studio or media room, or want privacy between rooms, plaster is the best option.
Drywall doesn’t do a good job of blocking sound. However, you can improve its soundproofing by adding materials like acoustic plasterboard or insulation. These additions help reduce noise.
Insulation and Energy Efficiency:
Drywall is easier to insulate, which makes it more energy-efficient in most modern homes. The cavity behind drywall panels is ideal for adding insulation, which helps maintain comfortable indoor temperatures and reduces energy costs. Plaster, while providing some natural insulation due to its thickness, is harder to retrofit with additional insulation, especially in older homes.
Repair and Maintenance:
Repairing drywall is much simpler and less expensive compared to other materials. You can quickly and inexpensively repair most damages, whether it’s a small hole from a nail or a larger crack.
Plaster repairs, however, are more complex. You can repair small cracks. However, serious damage often requires a professional. This makes it more difficult to maintain good condition over time.
Fire Resistance:
Both plaster and drywall contain gypsum, which is naturally fire-resistant. However, plaster offers a higher level of fire resistance because of its density and the thicker application. This makes plaster an excellent choice for buildings where fire safety is a top priority. Drywall also provides fire protection, but it may not hold up as well as plaster under extreme heat.
Aesthetic and Finish:
In terms of aesthetics, plaster offers more versatility and a superior finish. Whether you’re looking for a smooth, polished look or a textured finish, plaster can deliver a more refined appearance. It’s also better suited for intricate architectural details and curved surfaces.
Drywall, although less visually appealing in its basic form, contractors can still finish it in a variety of textures. However, achieving a smooth, high-end finish with drywall is more difficult and less common.
Ease of Hanging Décor:
Hanging pictures, mirrors, and other décor items is easier on drywall. Its softer composition makes it easy to insert nails, screws, and anchors without much effort. Plaster, being harder and more brittle, requires more caution. You’ll need to use screws instead of nails, and it’s often necessary to drill pilot holes to prevent cracking.
