Drywall is the modern standard for interior walls, prized for its affordability, speed of installation, and DIY-friendly repairs. Plaster is an older, premium method that requires highly skilled labor. It offers superior durability, soundproofing, and a smooth, elegant finish not easily matched by drywall.
Additionally, plaster has superior soundproofing and fire resistance, enhancing both safety and comfort within the building. Drywall is the modern choice between the two materials. Composed of gypsum and two paper layers, drywall is appreciated for its ease of installation and cost-effectiveness.
The Pushpin Test
All you need to do is take a simple thumbtack and try to push it through your walls. If the pushpin penetrates the wall, you have drywall. If it doesn't, you have plaster. Pushpins will not penetrate a plaster wall without a hammer or some other extra force.
Drywall is significantly cheaper than plaster. While the raw material costs of the boards are comparable, plastering requires highly specialized, time-consuming labor that costs up to 1.5 to 3 times more to install than drywall.
Plaster is rarely used in modern construction primarily because drywall (gypsum board) is faster, significantly cheaper, and easier to install. While plaster is highly durable and offers better soundproofing and fire resistance, traditional multi-coat plastering requires highly skilled labor and lengthy drying times, making it inefficient for modern housing demands.
If you are looking for an alternative to traditional drywall, PVC wall panels (like Trusscore or Duramax) are a leading modern replacement. They install up to four times faster than gypsum boards because they eliminate the need to mud, tape, sand, or paint.
Whether you should replace plaster with drywall depends on the extent of the damage and your renovation budget. Only remove and replace if the plaster is severely cracked, falling off the lath, or if you need to gut the room to update plumbing and electrical. If the damage is minor, repairing the plaster or installing drywall over it is usually cheaper and less labor-intensive.
The most affordable options include MDF panels, PVC panels, and peel-and-stick wall coverings. These materials are lightweight, cost-effective, and come in a wide range of textures and finishes, making them ideal for DIY projects and budget-conscious makeovers.
Two common mistakes made during drywalling are improper joint compound application (such as applying it too thickly or not feathering the edges), and failing to stagger the seams across different studs, which weakens the wall and increases the risk of cracking.
Yes, you can drill into plaster, but it is brittle and prone to cracking, so you must use the proper tools and go slowly.
1950s: Paper-faced drywall replaced earlier versions, further improving the strength and durability of drywall. Paper-faced drywall was smoother, allowing for a more straightforward application and aesthetically appealing appearance.
Most homes today have either drywall or plaster walls. Drywall is lighter and easier to work with, so most picture hanging hardware goes in cleanly with minimal effort. Plaster is denser and more brittle, so it can crack if you're not careful and usually needs more deliberate drilling and sturdier anchors.
As time passes, plaster is continually curing harder and harder making it more fragile than drywall. In areas with high traffic, cracks are common in walls and especially ceilings, which can be shattered by age and gravity.
In Canada and the United States, wood lath and plaster remained in use until the process was replaced by transitional methods followed by drywall (the North American term for plasterboard) in the mid-twentieth century.
Drywall can last around 30-50 years, depending on the quality and maintenance, but it's more prone to damage from moisture or impacts. Plaster, on the other hand, is more durable and can last over 100 years if properly maintained, making it a better long-term investment for older homes.
Drywall alternatives like plywood, plaster, and shiplap provide options for those seeking unique aesthetics or improved functionality in wall finishes. While drywall is affordable, easy to repair, and fire-resistant, these materials offer benefits that might better suit specific needs.
Before the widespread adoption of drywall in the 1940s and 1950s, older houses used a method called lath and plaster. This technique consisted of nailing thin wooden strips (lath) horizontally across wall studs and coating them in thick layers of plaster.
How long does it take to plaster a 3 bedroom house? It will take between 5 to 8 days on average to complete the plastering of a 3 bedroom house. This however depends on the job requirements and whether you are having a full replaster or a simple skim.
The cheapest way to replace or update a ceiling is to cover the existing damaged ceiling rather than tearing it down. You can cover it using paint, adhesive styrofoam ceiling tiles, or by installing a Trusscore Wall & Ceiling Board system, saving thousands in demolition and disposal costs.
If your home was built up through the mid 1920s it is very likely that it was built with lime plaster. Applied in three coats, it was a mixture of quick lime, water, sand and animal hair.
Speed of Installation: Drywall panels can be quickly and easily installed, significantly reducing construction time compared to traditional plaster methods. Cost-Effectiveness: It is generally less expensive to install drywall than to apply plaster, making it a cost-efficient option for large and small projects alike.
How can I tell if my wall needs plastering or skimming? Plastering is needed for new builds, heavily damaged walls or structural repairs. Skimming is suitable for cosmetic updates, minor imperfections or refreshing older plaster.
