There are many wall and ceiling materials options when constructing or remodelling a home or business. Plaster and drywall are two of the most widely used materials. However, despite their superficial similarities, important distinctions between the two materials should be taken into account when deciding which one to use.
When selecting building materials, it is helpful to have a solid understanding of the distinctions between plaster and drywall in order to make an educated choice.
What Is Plaster?
Plaster has been used to coat walls and ceilings since the time of the ancient Egyptians. In addition, plasters made of clay and lime were used to coat the outside of ancient monuments and temples for protection.
Plasterboard and wet plaster are the two most common plaster varieties used today. Plaster of Paris, commonly known as wet plaster, is made by mixing powdered clay, cement, sand, lime, or gypsum with water. When combined with water, this plaster powder can be worked into a slurry or thick paste and applied to walls with a trowel.
Plaster and stucco share some of the same ingredients, so the two might need clarification. However, while both can cover flaws in a finish coat, plaster creates a smooth surface, while stucco is an ornamental plaster that gives off a more rustic vibe.
Different Types Of Plastering
Plastering is a common construction technique to create uniform and smooth wall and ceiling surfaces. Plastering comes in a variety of forms, each with its own set of advantages and disadvantages. Learning about the various plastering options can help ensure that the best one is chosen for any job.
Plastering comes in wide varieties, from the time-honoured lime plaster to the more contemporary gypsum plaster, and each has its own set of benefits and drawbacks. In this piece, we will discuss the various kinds of plastering as well as the uses for each.
Cement Plaster
Plaster made from cement is widely used in building and remodelling projects. Plaster is a cement, sand, and water coating applied to surfaces like walls and ceilings. Floats, Trowels, brushes, and other tools are used in the application process to spread the coating evenly and precisely.
Cement plaster is typically applied in two phases: scratch and finishing coats for increased protection and durability. Cement combined with a coarse aggregate like sand or gravel forms the scratch coat, while cement with finer materials like lime or gypsum forms the finish coat, creating a smoother surface. After it has dried properly, cement plaster can serve as a durable, aesthetically pleasing surface that can be painted over if necessary.
Gypsum Plaster
Gypsum plaster is a common building material that creates a flat, uniform surface on walls and ceilings. A paste-like material is created by mixing calcium sulphate hemihydrate, water, and sand.
The smooth, long-lasting finish that gypsum plaster provides can be painted or left unfinished, depending on personal preference.
In most cases, it is troweled on in several layers, with each layer being given time to dry in between. Plaster made from gypsum does a better job of insulating than lime and does not need to be cured.
Gypsum plaster has a long lifespan and requires nothing in the way of repairs or replacements if cared for properly. It also has many practical uses, such as making decorative effects and fixing broken surfaces.
Lime Plaster
Lime plaster has been a standard building material for generations. It is applied to ceilings and walls to make a more permanent finish and is made of lime, sand, and water.
Depending on your aesthetic preferences, you can paint over lime plaster or leave it natural. To ensure uniformity, the coat of plaster is applied with a straight steel edge, wooden float, and other instruments.
Different methods, such as sand-faced and rough-cast finish, are employed depending on the desired result. Lime plaster protects against moisture and other factors and gives a building a more aesthetically pleasing look. In addition, plastered surfaces can last for many years with only occasional maintenance and repair if treated with the care they deserve.
Mud And Clay Plasters
Plasters made from clay and mud have been used for centuries in building and remodelling. To create this substance, natural clay & mud are mixed with other components like straw and waste to make a thick paste.
Interior and exterior walls can benefit from the long-lasting finish that clay and mud plasters provide. They work particularly well for making decorative patterns and designs in the form of swirls and geometric shapes on the walls and ceilings.
When it comes to home energy efficiency, clay and mud plasters are a more economical option than traditional lime plasters because of their superior insulation properties.
You can apply them using a trowel or a wooden float in many coats to achieve different effects, such as a smooth finish or a rough surface. Plasters of clay and mud can last for decades if properly maintained and cared for.
Pros And Cons Of Using Plaster
The use of plaster as a construction material dates back thousands of years. It is commonly used for walls and ceilings because of the ease with which it can be produced from a combination of lime, gypsum, sand, and water.
The use of plaster comes with a number of drawbacks, despite the fact that it does offer some benefits. The following are some of the benefits and drawbacks of using plaster:
Pros Of Using Plastering
- Durable: Plaster is an extremely long-lasting building material that can last for many years with the right kind of care and upkeep. It is not easily scratched or dented and is durable enough to withstand general wear and tear.
- Gives a smooth finish: Plaster's uniform sheen can make for more aesthetically pleasing walls and ceilings.
- Fire-resistant: Plaster is resistant to fire, making it a more secure material to use in the construction of buildings. It can assist in bringing fires under control and halting their progression.
- Sound insulation: Plaster is useful for soundproofing because it can lessen the amount of noise that travels through walls.
Cons Of Using Plastering
- Difficult to install: When compared to more common wall coverings like drywall, plaster can be a real pain to put up. A higher level of expertise and experience is needed for application and completion.
- Prone to cracking: Plaster is a material prone to cracking and often needs routine maintenance to prevent and repair cracks.
- More expensive: Plaster is more pricey than other common wall coverings like drywall and panelling. It may increase building expenses.
- Not moisture-resistant: Plaster is easily damaged by water because it is not very water-resistant. If it gets wet, it can also serve as a prime location for the growth of mould and mildew.
What Is Drywall?
Drywall, also known as wallboard, sheetrock, cement board, or gypsum board, can be purchased as either prefabricated panels or as a joint compound. Gypsum (calcium sulphate dihydrate) is used to make drywall panels with paper facings on both sides. The board's shape is preserved, allowing drywall screws or other fasteners to be used during installation.
Drywall panels are used to cover the studs and insulation in a wall in a new home. Some manufacturers produce drywall with added functionality or compliance with local building codes.
Greenboard, on the other hand, outperforms gypsum plaster blue board in terms of resistance to mould and water. The latter is made from staggered paper layers to give the impression of plaster. In addition, basements and workplaces can benefit from soundproof drywall, which is available for purchase.
Different Types Of Drywall
Drywall is commonly used for interior walls and ceilings in residential and commercial construction. It is available in many forms, each with advantages and disadvantages, and it can be installed quickly and cheaply. If you know what kinds of drywall are available, you can choose the right kind for the job.
There are a wide variety of drywall options, from standard drywall to moisture-resistant and fire-resistant varieties, each with its own set of benefits and drawbacks. Various drywall varieties and their uses will be discussed here.
Regular Or Standard Drywall
Normal drywall is drywall that has yet to be upgraded in any way. However, it competes on par with other types and is not inferior to any of them. You won't find any frills here.
For instance, regular drywall is already fireproof (Gypsum's water molecules act as a firebreak, preventing rapid conflagration), but fire-resistant drywall adds even more protection.
Mould-Resistant Drywall
This drywall, which is commonly purple, is resistant to the growth of mould and mildew. In addition, this drywall has been treated specifically for use in high-humidity environments.
It is more costly than regular drywall and an expense that can add up quickly; however, considering that mould and mildew are sneaky and can cause health problems, the additional cost might be justified.
Moisture-Resistant Drywall
Water can be destructive. The majority of homeowners will experience this at some point. Drywall with a special coating designed to repel moisture can reduce the severity of water damage. It works wonderfully in damp environments or near water sources, such as bathrooms and kitchens.
Cement board, which is even more water-resistant than regular drywall, is the material for use in wet environments such as bathrooms.
The names "green board," "interior tile backer board," and "cement board" are all used to describe this drywall product. The term "blue board" can also refer to water-resistant drywall. Because it is designed to be covered with veneer plaster, this product is distinct from others on the market.
Fire-Resistant Drywall
Garages, bedrooms, apartment buildings, and many commercial buildings are just some of the places where building codes require fire-resistant materials (Type X, fireboard, or X board).
Type X drywall has enhanced fire safety features in comparison to standard drywall. For example, type C provides up to four times as much protection as Type X, which only lasts an hour.
Drywall designed to withstand fire is made with special fibres that are not flammable. It's also considerably thicker than standard drywall. Altogether, they reduce the speed at which a fire can spread, giving people more time to escape and reducing the amount of property damage.
Pros And Cons Of Using Drywall
Drywall, also called plasterboard or gypsum board, is frequently used for interior walls and ceilings in residential and commercial construction. Drywall has some benefits, but it also has a few disadvantages. The benefits and drawbacks of drywall are as follows:
Pros Of Using Drywall
- Easy to install: When compared to the installation of other wall materials, such as plaster, which requires a higher level of expertise and experience, installing drywall is a relatively simple process.
- Affordable: Drywall is a great option for reducing construction costs. Construction can help keep costs down because it is more affordable than many alternatives.
- Fire-resistant: Drywall is safer than other building materials because it does not easily catch fire. It can be used to prevent fires from spreading and to keep them contained.
- Sound insulation: Drywall is an excellent option for buildings that need sound insulation because it can help reduce the amount of sound that travels from room to room.
Cons Of Using Drywall
- Prone to moisture damage: Drywall is easily damaged by water because it is not very water-resistant. If it gets wet, it can also serve as a prime location for the growth of mould and mildew.
- Not eco-friendly: Drywall is not an environmentally friendly or sustainable building material because its production requires significant energy and resources.
- Damaged or dented easily: Drywall isn't sturdy and will easily dent or crack if hit. A building with young children or active pets may have this issue.
- Difficult to repair: Fixing drywall damage, especially extensive damage, is a task that can be challenging and time-consuming.
Conclusion
Two common building materials for interior walls and ceilings are plaster and drywall. Ancient Egyptians were the first to employ plaster for wall and ceiling coverings. Most modern constructions make use of either plasterboard or wet plaster.
Mixing powdered clay, cement, sand, lime, or gypsum with water results in Plaster of Paris, also known as wet plaster.
While both plaster and stucco include some similar elements, the finishing coat of any material can hide imperfections.
Different kinds of plastering have their own benefits and drawbacks.
Cement plaster is a covering made of cement, sand, and water that is commonly used in construction and renovation.
Gypsum plaster is a popular choice for finishing walls and ceilings because it dries flat and homogeneous. Sand, water, and calcium sulphate hemihydrate combine to form this paste-like substance.
When properly maintained, gypsum plaster can survive for decades without needing any touchups or replacements.
Making use of lime, sand, and water, lime plaster has been a standard construction material for many years. It's made of lime, sand, and water, and it's used as a more lasting finish for ceilings and walls. You can either paint over lime plaster or leave it unfinished.
Plasters made from clay and mud are less expensive and, if cared for, can survive for decades.
There are benefits and drawbacks to using plaster. It's a better material for building construction because it's long-lasting, fireproof, and muffles noise. It's also helpful for soundproofing, blocking sound waves before they penetrate walls.
Drywall is available in both prefabricated panels and joint compound forms. It is also known as wallboard, sheetrock, cement board, and gypsum board.
Drywall is constructed from gypsum boards that have paper on both sides for easy fastening with drywall screws or nails.
Some manufacturers create drywall with additional functionality or compliance with local building requirements, and these panels are used to cover studs and insulation in a new home.
Drywall, often called plasterboard or gypsum board, is commonly used for interior walls and ceilings in both homes and businesses.
It's available in a variety of formats, each with its own set of pros and cons.
Standard drywall, mould-resistant drywall, moisture-resistant drywall, and fire-resistant drywall are just some of the options.
Drywall is available in two varieties, one of which is resistant to mould and mildew growth but not fire.
Cement board is even more water-resistant than moisture-resistant drywall, making it an excellent choice for bathrooms and other damp areas.
Places like garages, bedrooms, and apartments all need fireproof drywall. Type X drywall has extra fire protection characteristics because of its thicker materials and unique fibres.
Drywall's benefits include its low price, low maintenance, resistance to fire, and ability to muffle noise.
It is subject to harm from moisture because it is not highly water-resistant. Denting or scratching it makes repairs costly, and it's not good for the environment. It's also not a good idea for apartments with kids or pets who want to run around.
