Drywall is made out of softer material called gypsum which doesn’t crack. Sheets of it are nailed into the wooden studs when finishing the interior of a house. Plaster, on the other hand, dries much harder than drywall, and is more labor-intensive and expensive.
How can you tell the difference between drywall and plaster?

Is it better to plaster or drywall?

However, even though plaster is denser, it can’t beat the thermal capabilities of standard drywall coupled with modern insulation commonly found today.
Is drywall made of plaster?
Drywall boards and plaster boards are traditionally made from gypsum. The mineral has high water content, giving drywall it’s fire-resistant properties. The gypsum is mixed with other additives like recycled paper pulp to create a slurry or paste.

Plaster doesn’t produce any dust except for a small amount released when water is first added to the powder.
What are the disadvantages of using drywall?
Drywall can be easily damaged since it’s not resistant to impact. So, you might have problems with holes, damaged corners, tapes coming off, and joints cracking. The good news is that there are drywall repair solutions for such problems.
What is the life expectancy of drywall?
Plaster and/or drywall walls and ceilings have an expected life span as long as 70 years but as short as 30 years. Water leaking in from the roof or exterior walls can greatly reduce the life of plaster and drywall and cause cracks and defects.
Should I replace lath and plaster with drywall?
Since plaster is considered a higher quality material than drywall anyway, it should not be replaced with drywall in most situations. The one exception is if you’re pulling down the walls to replace the plumbing and electrical systems anyway. In that case, it makes sense to replace with drywall.

Are plaster walls good?
Plaster has many advantages over modern drywall. It provides better insulation, fireproofing and soundproofing than drywall. Also, unlike drywall, it will not harbor mold because mold cannot grow in it. Because it is hand applied by skilled artisans, it is a higher quality, more expensive material.
Do plaster walls crack easily?
A: Old lath and plaster walls are prone to cracking. Over time the plaster separates from the lath, creating structural cracks. Plaster is also prone to thinner spider-web cracks, which occur when the topcoat of the plaster degrades. It’s common to have both kinds of cracking — and both types can be repaired.
Are plaster walls durable?
If properly mixed and applied, a plaster coating creates a stronger and more durable wall finish than drywall. The walls become stronger due to the chemical reaction that takes place when water escapes the plaster mixture. Plaster is more resistant to knocks and dents in most cases.
Can you nail into plaster walls?

Are there studs in plaster walls?
It’s pretty simple to find a stud in common drywall. Plaster can be too thick or dense to find a stud with stud finders, which is probably why you’re finding that these don’t work. And if the lath is a metal wire type, instead of older wood lath, a stud finder will produce false readings.
