    People think about granite countertops, square footage, and windows when building or remodelling. Interior walls, a key part of a home, are often overlooked.

    Unless there's a problem or they move into a studio, most people don't think about their walls. Interior walls provide privacy. They can block sound, insulate, and resist fire.

    Plaster and drywall are popular wall materials. Plaster is ancient. Lime, sand, animal hair, and water were used to make early plaster. Queen Nefertari's tomb has paintings on its plaster walls. Frescos decorated ancient Roman homes. Frescos are painted on wet plaster with pigments.

    Gypsum-based plasters dry faster than lime-based plasters. This new plaster was popular because it sped up construction.

    Drywall became more durable and available as technology advanced. Drywall became a popular interior wall material in the 1950s. It covers most modern homes' interior walls.

    This article compares plaster and drywall for interior wall applications.

    Types of Plaster

    Plaster's everywhere. This mix of gypsum, cement, sand, and water has many uses. Did you know about plaster types?

    Different types of plaster have different uses and mixing methods. If you're into building, art, or medicine, this article will be very helpful, as we'll look at the different plasters available and what you need to know about them. By the end, you should be able to decipher all the different types of plaster to complete your tasks.

    Browning plaster

    This is a base for paint and other decorations. Similar to bonding plaster, but for absorbent surfaces. They can build walls and are useful in construction. Most builders use 8mm browning plaster on ceilings and 11mm on walls.

    Before doing anything else to the walls, a finish coat is applied. Browning plaster's drying time depends on the weather and season, but most experts and enthusiasts advise leaving it for a day before working on it.

    Bonding plaster

    Bonding plaster is an undercoat like browning plaster. Due to its versatility and stickiness, it's more popular for building. It's used on all surfaces, including concrete and engineering blocks. It doesn't rely on surface absorption, making it the ideal wall plaster. Bonding is usually 8mm for ceilings and 11mm for walls, like browning plaster.

    It's an undercoat plaster, so it's applied to a newly patched wall first. When levelled, a nail is used to provide a 'key' for the topcoat.

    Thistle plaster

    Thistle plaster is a finish coat, applied after bonding and browning. It's popular because it's versatile and easy to use. Small plaster repairs and other common tasks favour it.

    Thistle plaster can be used on plasterboard or in two-coat systems. It can be applied manually or mechanically, adding to its appeal. Its quality also contributes to its popularity because it provides a smooth surface for decorative finishes.

    Carlite plaster

    Carlite is a finish coat used over a background, like thistle plaster. Carlite plaster can be used on a variety of surfaces, then decorated.

    Carlite takes three hours to set while thistle takes half as long. Thistle is popular, but carlite is also durable. Carlite is scratch-resistant and hard.

    Hardwall plaster

    Plaster that is referred to as hardwall is an undercoat plaster that is most frequently utilised with masonry backgrounds such as bricks and medium-density blocks. Hardwall is an ideal base to work with, just like the other undercoat plasters we've discussed; additionally, the fact that it is simple to apply is one of the reasons why it is so widely used.

    Having said that, it is recommended that you utilise hardwall on structures that are in good condition. This is because a wall that is in poor condition or that is crumbling could cause the plaster to crack.

    Dri-coat plaster

    Dri-coat plaster is used after installing a damp-proof course (DPC.) Dri-coat plaster prevents the movement of hygroscopic salts. Hygroscopic salts absorb atmospheric moisture, causing damp walls. Dri-coat plaster protects and preserves walls.

    Dri-coat is ineffective on frozen backgrounds. Plaster does little to reduce the spread of fire, so you should avoid exposing it to high temperatures.

    One Coat plaster

    One coat plasters are more versatile than undercoat or finish plasters. It's both an undercoat and a finish. It's a popular plaster variant because it's easy to use and requires fewer steps. One coat plaster, made from traditional gypsum, is thicker than other variants, allowing for thicker layers.

    Easy to apply by hand or with mechanical tools. One-coat plaster saves time because it doesn't require a scratch coat or other step. One coat is used for repairs because it's easier to get a smooth finish on smaller areas.

    Tough coat plaster

    It is a type of undercoat plaster that, as the name suggests, is very tough and is able to handle conditions that other types of plaster simply are not capable of handling. For instance, it offers some protection against fire, and although it is not recommended to use it on frozen walls, it is still capable of doing a decent job in that situation. In addition to this, it has a high resistance to impact and works exceptionally well as a foundation for masonry backgrounds.

    Six Ways Of Modern Plaster Walls

    Have you been finding that you are staring at walls a lot recently? We are aware that we have. Plaster, in all of its beguiling guises, is making a significant comeback, which is why this is the case. Plaster finishes give interiors a depth and luminosity that change with the light, subtly transforming the look and feel of a home in the process.

    In addition, there is no need to paint it: Plaster, when left in its natural state, is an environmentally responsible natural material because it is breathable and free of chemicals and volatile organic compounds (VOCs).

    True, plaster walls are more expensive than painted drywall; that’s because they’re more labor intensive to install (most require at least three coats). But they’re also typically longer lasting and more beautiful. For interior applications, here are six main categories to consider illustrated by some of our favorite projects of late.

    It is important to investigate the substrate requirements prior to applying plaster in your own home. Plasters of all types and brands are required to adhere to a surface, but the method by which this is accomplished varies, as does the durability and waterproofness of the specific plaster. Skill with a trowel and patience are required, as you must wait for each layer to dry before proceeding.

    Clay Plaster

    Clay plaster is so healthy, chemically sensitive people often use it. Powdered in earthy shades, it has matte, often rough finishes. Clay plaster's moisture-absorbing (and desorbing) abilities make it a humidity regulator in other rooms. To use, mix with water on-site and apply in four or five layers to a sanded, primed surface.

    Slaked Lime Plaster

    Your great-grandparents' plaster walls were made of this. Starting with wood lath, a "scratch coat" (plaster mixed with shrinkage-preventing horse hair) was applied, followed by a "brown coat" (plaster mixed with sand) and a fine skim coat. Hydrated—or slaked—lime plaster is made from limestone that has been baked at high temperatures to remove impurities. Unlike other options, you don't have to hand-mix it and you have more time to apply it.

    Basic white, it now comes in many colours. Unpainted, it absorbs and releases moisture like clay plaster, but can be used in kitchens and bathrooms (but not directly in water). If desired, add bee's wax or Marseilles soap.

    Gypsum Plaster

    Plaster made of gypsum is available in powdered form, and it is more subdued and picky than slaked lime. As soon as it has been activated, gypsum plaster typically needs to be applied within 35 to 40 minutes after it has been mixed with water and activated. (If you stop in the middle of the process, you will develop weaknesses known as "cold joints," and you will have to start over.) In comparison to lime plaster, it is also more cost-effective and requires a lower total number of coats. In addition to that, you can tint it to fantastic effect.

    Venetian Plaster

    The term "Venetian plaster" refers to the product that results when pigment is added to aged slaked lime plaster (not to be confused with any paints that use that name). You can achieve a high level of polish and sheen by including marble dust in the mixture.

    Tadelakt is a traditional Moroccan finish that has been around for centuries and is exceptionally long-lasting. It is made of lime plaster and black soap that is made from olives. Because of a chemical reaction that occurs between the two ingredients when they are combined, tadelakt walls are the most suitable of all plasters for use in showers and baths, and even as sinks and tubs — it's practically synonymous with Moroccan hammans. Read all about it in our Remodeling 101 post.

    Neo Plaster

    Numerous businesses are in the process of developing their very own plaster wall finishes that are simple to put up. These frequently contain acrylics as well as other components that speed up the process and reduce the number of coats that are required.

    FAQs About Drywall & Plaster

    Skim-coating with all-purpose joint compound is an effective way to blend the two materials. To skim coat, you lay a thin coat of mud on the entire wall and scrape it flat with a drywall knife. Another way to match the surfaces is to roll dilute mud on the wall with a paint roller to create a mottled texture.

    Lath and plaster walls are usually thicker than most drywall sheets. Fire-rated, or Type-X, drywall is 5/8-inch thick. Plaster is often thicker than this. When lath is figured into the thickness, then lath and plaster walls are considered to be thicker than drywall.

    You can readily cut holes in drywall to make in-wall repairs, and holes are easy to fix. Drywall is cheaper to install than plaster. It's easier to hang things on drywall.

    Drywall mud will adhere to plaster walls, making it simple to patch plaster with a standard joint compound. By taping joints and applying multiple coats of joint compound, you'll quickly fill holes and patch larger areas.

    By applying plaster, you will give your walls a strong, smooth, durable finish. Not only that, but a well-plastered room will help to keep old walls in good condition, provide the perfect base for paint and help with soundproofing.
