So, what's the difference between drywall and plaster?
If you're planning a house renovation, knowing what's the difference between drywall and plaster is the first step to figuring out your budget and just how much associated with a headache the project might turn out to be. It's one of those things most people don't think about until they try to hang a heavy picture frame or notice a crack spidering across the ceiling. While they will both result in flat, paintable areas, they are sides apart in conditions of how they're made, the way they tone, and how they'll treat your pocket.
For the majority of associated with human history, in case you wanted a wall, you were getting plaster. It wasn't until around the mid-20th century that drywall—often called sheetrock—started overtaking the design world. Today, almost every new home is built along with drywall, while plaster has become a bit of the "lost art" found mostly in historic homes or high end custom builds. Let's break down why these types of two materials are usually so different and which one may be hiding at the rear of your wallpaper.
The Traditional Method: How Plaster Works
If your house was built prior to the 1950s, there's a very high chance you possess plaster walls. Plastering is a labor-intensive build that needs a lot of skill and even more endurance. In the day, builders would nail numerous thin wooden strips, called lath , horizontally across the wall studs. After that, a craftsman would smear layers of wet plaster over those strips.
The magic happens when the plaster "oozes" through the gaps in the wood. When this dries, it creates these little hooks called secrets that lock the plaster to the wall. Usually, it's the three-coat process: the scratch coat (to get those keys set), the brown coat (to degree things out), and finally, the finish coat (the smooth part you really see).
Because it's applied wet and by hand, plaster is incredibly heavy. It's almost like creating a thin coating of rock over your walls. This particular helps it be feel quite solid—if you knock on a plaster wall, it won't sound hollow; it'll feel like bumping on the sidewalk. It's also naturally fire-resistant and does a fantastic job associated with blocking out sound from the next room.
The Modern King: Understanding Drywall
Drywall changed everything because it made creating a house much, considerably faster. As the title suggests, it's a "dry" process—mostly. Drywall consists of a core of gypsum (a soft sulfate mineral) sandwiched between two thick bedding of paper. It comes in big, heavy panels, generally 4x8 feet, that are simply screwed straight into the wooden or metal studs of the house.
The only "wet" part of drywall is the finishing. Once the planks are up, you have seams where they meet. The contractor applies document or mesh video tape over those stitches and covers them with layers of joint compound, or even "mud. " As soon as the mud dries, they sand it down until it's smooth and unseen.
It's efficient, it's cheap, and almost anybody having a bit associated with grit and the YouTube tutorial can learn how to get it done. That's exactly why it's the regular today. It doesn't need a master craftsman; it just requires a steady hand and a good sanding mask.
Audio, Insulation, and the "Feel" of the Area
One of the biggest functional variations you'll notice will be how your home noises. Because plaster is usually so thick and dense, it's a fantastic sound dampener. If you live in a good old plaster-walled residence, you might hardly hear your neighbors. In a modern drywall home, you might hear a sneeze three rooms away.
Drywall is essentially a hollow sandwich. There's the board, a big gap associated with air (usually filled with insulation), and after that another board. When you can buy specialized "soundproof" drywall, standard plaster still generally wins the sound battle.
After that there's the visual. Plaster can be molded and curved. If you view a house with stunning arched doorways or even curved corners, that's almost certainly plaster. Drywall is firm. While you can curve it with enough water and effort, it's really designed for flat areas and 90-degree angles. Plaster has a certain handmade "soul" to it—it's by no means perfectly flat within the way the factory-made board will be, which gives older homes their personality.
Which 1 Is Harder to Repair?
This is where the drywall vs. plaster debate gets true for homeowners. If you need in order to run new electrical wiring or repair a plumbing outflow behind the wall, you're going to have to reduce a hole.
With drywall , this is a breeze. You reduce out a square, do your work, screw in a new new part of plank, tape it, dirt it, and you're done. It's such as a puzzle piece.
With plaster , it's the nightmare. Plaster will be brittle. When you try to cut straight into it, it is likely to crack and crumble. Often, the vibrations from a saw can result in the "keys" on the to crack off, meaning the plaster starts pulling away from the wood lath. Before long, a small gap has changed into a massive piece of the wall falling off. Plus, matching the structure of old plaster with modern components is definitely an art form that many contemporary contractors haven't mastered.
The Cost: Why Drywall Usually Wins
In the event that you're building the new addition and wondering what's the difference between drywall and plaster relating to your bank accounts, the answer is definitely simple: plaster is more expensive.
The material cost intended for plaster isn't really that bad, but the labor cost is astronomical. It takes days, if not weeks, for a multi-coat plaster job to dry and be completed. Drywall could be strung in a day and finished in a few more. Because time is definitely money in building, drywall is nearly always the more economical choice. You're also going in order to have trouble even obtaining a professional plasterer these days. It's a niche business, and they charge accordingly.
Exactly how to Tell What You Have
If you aren't sure what's in your walls, generally there are two simple ways to discover out.
- The Thump Test: Give the wall a good knock. Does it tone like an empty drum? That's drywall. Does it seem like knocking on a solid brick? That's plaster.
- The Pushpin Check: Try to push the simple thumb tack or pushpin straight into the wall. If this goes in relatively easily, you've obtained drywall. If the pin bends or even will not budge, you're dealing with plaster.
Durability and Cracking
Plaster will be incredibly tough, yet it doesn't manage "settling" perfectly. As a house shifts over the years, plaster doesn't bend; it cracks. This is the reason you see those long, jagged lines in the ceilings of old Victorian houses.
Drywall is a bit more forgiving. It's softer, therefore it can handle a little bit of movement without instantly splitting. However, drywall is very susceptible to water damage. In case a pipe leaks, drywall turns into the soggy sponge and starts to grow mould almost instantly. Plaster, being a lot more like stone, deals with moisture a bit better (though the wood lath behind it can still rot).
Final Thoughts: Which Is Much better?
There isn't a "winner" right here, only what's right for your particular circumstance. If you're living in a historic home, you'll most likely want to stick with plaster in order to maintain the worth and the traditional acoustic soul of the house. It's reduced product that feels high-end.
However, for most associated with us doing a basement renovation or renovating a spare bedroom, drywall is definitely the practical choice. It's faster, less expensive, and way easier to fix when your kid accidentally kicks a soccer ball through the wall.
From the end of the day, knowing what's the difference between drywall and plaster can help you respect the workmanship of the recent while appreciating the convenience of the present. Whether you're dealing with messy moist plaster or dirty drywall sanding, at least you'll know exactly what you're getting into just before you grab the hammer.
