What Is The Purpose Of Plasterboard In Construction?

Plasterboard, known as drywall, is commonly used in buildings to construct walls and ceilings. Gypsum plaster is used to create this material, encased in either paper or fibreglass mats. Many contractors and homeowners prefer Plasterboard because it is inexpensive, versatile, and easy to work with. 

Plasterboard is commonly used in construction because it creates a uniform surface that is easy to paint or paper.

Plasterboard serves a purpose, has a number of benefits, and is installed in a manner that is going to be extensively covered in this article.

What Exactly Is Plasterboard?

Plaster has been widely used as an interior wall finish in many countries for centuries. Plaster is a thick paste made from water and the mineral gypsum that is applied to walls, smoothed out, and then painted by the building's owner to protect them from the elements.

Plasterboard is just a more convenient replacement these days. Plaster is made by combining gypsum with water and foaming agents. The sludge is then baked in ovens between two sheets of heavy paper. This approach yields plaster sheets that are completely flat and can be mounted to walls in a fraction of the time required by hand-applied methods.

What Is Plasterboard Used For? 

Plasterboard can be attached to studs or masonry walls like a brick in residential and lightweight framed commercial construction to create walls. In addition to its use as a ceiling material, it is also shaped into arches, eaves, and curved walls for decorative purposes. Plasterboard columns can hide steel beams and finish off masonry walls in commercial buildings.

Uses Of Plasterboard

Plasterboard, or Gypsum Board as it is sometimes called, is a common and durable construction material.

Most people associate these boards with interior construction, but they can be used for much more. Because of its adaptability, it can be used in a wide variety of settings, some of which are described below.

Ceiling

They are as common in ceilings as they are in walls. Their low weight makes them ideal for ceilings suspended from the ceiling.

Because of their high acoustic insulation properties, they are frequently used in ceilings to lessen the noise heard from one floor to the next.

Wall

The most typical use is for constructing walls inside a building. The Plasterboard is fastened to a wood stud or metal frame, or the studs are covered. They work wonderfully as privacy or divider walls.

In addition, they are frequently used to clad interior walls because they are such a good alternative to plaster. They create a flat, even surface ideal for applying paint or wallpaper.

Fire Resistance

When it comes to fire safety, Plasterboard is hard to beat. First, a fireproof Plasterboard can withstand intense heat without melting. If installed properly, Plasterboard can slow the spread of fire, giving people more time to get out of the building.

Sound Insulation

Plasterboard is also commonly used as a means of acoustic insulation. For example, it can lessen the noise that echoes through hallways and bedrooms. In addition, Plasterboard is commonly used for soundproofing in recording studios, movie theatres, and other similar environments.

Benefits Of Using Plasterboard

Durability

Plasterboard is a long-lasting construction material that can handle daily use. High-traffic areas of buildings can benefit from its durability because it is not easily damaged. Plasterboard has a long lifespan, provided it is installed and maintained correctly.

Cost-effective

Plasterboard is an inexpensive, accessible, and portable building material. It's more cost-effective than brick and concrete, for example. Because of this, it's a common option among builders trying to cut costs without reducing standards.

Easy To Install

Plasterboard is a popular material among construction professionals because of its low price and simple installation. It's easy to cut and hang and can be finished to look sleek and uniform. The construction project could benefit from the time and money savings this provides.

Versatility

The construction industry makes extensive use of Plasterboard because of its adaptability. It's versatile enough to be used for anything from straight walls to curved walls to ceilings. In addition, because it is so easy to cut and shape Plasterboard to specific dimensions, it is frequently used by architects and designers.

Types Of Plasterboard

Different kinds of Plasterboard serve different functions. Below, we've outlined the most common varieties in use.

Standard Plasterboard

One such variety is the common Plasterboard, which serves a variety of purposes. Simple ceilings and walls are perfect applications for them. Durability is one of their hallmarks.

Fire Resistant Plasterboard

The primary goals of development for this category were heat resistance and containment of fires. In addition, special additives, such as glass fibres, make this Plasterboard.

Plasterboards designed to withstand fire do so to a much greater degree than their non-resistant counterparts. They are commonly sold in pink for ease of recognition.

Flexible Plasterboard

These boards are often called curved or bendable plasterboards because of their malleability. However, because of their construction, they can easily be bent into complex arched or curved forms.

They are used to make arches and domes due to their malleability and versatility. Curved sculptures are another common application.

Sound-insulating Plasterboard

These plasterboards have a secondary use as noise barriers. They're great for blocking out noise between levels or rooms. Its one-of-a-kind centre is made from materials that absorb sound waves, making it less disruptive to those around you.

Plasterboards designed to dampen ambient noise are best used in quiet spaces like bedrooms and recording studios.

Moisture Resistant Plasterboard

These gypsum boards were created with moisture resistance as their primary design objective. These can typically be discovered adorning the walls of kitchens and bathrooms.

Plasterboards designed to resist moisture are manufactured with specialised additives that make them more water-resistant.

Thermal Plasterboard

Thermal Plasterboard, also known as insulated Plasterboard, is manufactured with superior thermal insulation qualities. As a result, they contribute to the building's improved energy efficiency.

They work well to lessen heat loss via the roof and walls. Thermal boards get their heat-blocking properties from a layer of rigid foam adhered to one side.

Ceilings, exteriors, and interiors can all benefit from their installation. Depending on your specific requirements, you can choose from various plasterboards. First, determine the function of your installation, and then go with that.

Installation Of Plasterboard

Plasterboard must be installed correctly for the best possible finish. The fundamental steps of installation are as follows:

Wall Or Ceiling Preparation

Plasterboard installation requires a smooth, dry, and dust-free surface. Therefore, getting the plumbing and electrical work done before installing anything is important.

Plasterboard installation necessitates careful surface preparation before it can be applied. Plasterboard will adhere better if the surface is clean, dry, and free of debris before installation. To get your wall or ceiling ready, do as follows:

• Clean the surface: Any dust or debris on the wall or ceiling should be removed using a soft bristle brush or a vacuum cleaner. This is crucial for achieving optimal plasterboard adhesion.
• Check for moisture: It's important to wait until the surface is dry before putting up the Plasterboard. Plasterboard's ability to adhere can be compromised by even a small amount of moisture, which can encourage mould and mildew growth.
• Remove any wallpaper or loose paint: Plasterboard installation requires the removal of any loose paint or wallpaper from the wall or ceiling. A putty knife or scraper will do the trick here.
• Repair any holes or cracks: Plasterboard shouldn't be hung until any holes or cracks in the wall or ceiling have been fixed. You can use filler or joint compound for this.

Plasterboard Measurement And Cutting

Plasterboard needs to be cut to the exact dimensions of the area it will be installed in. To make cuts, you can use a saw or utility knife.

Plasterboard must be measured and cut precisely to ensure a proper fit when installed on a wall or ceiling. Instructions for sizing and slicing Plasterboard are as follows:

• Measuring the ceiling or a wall: Measure the width and height of the wall or ceiling with a measuring tape. Put pencil marks where the dimensions should be on the sheet of Plasterboard.
• Cut the Plasterboard: You can use a utility knife to make cuts in the Plasterboard along the drawn lines. The board must be snapped with force along the score line. Keep adding points along the line until the board breaks. If you want perfectly straight cuts, score the Plasterboard with a straight edge.
• Make holes for the fixtures: To make holes in Plasterboard for electrical wiring, switches, and outlets, mark the desired locations on the board and cut them out with a plasterboard saw or a keyhole saw.
• Cut angles: Make a mark on the Plasterboard at the appropriate angle if the wall or ceiling has any. Snap the board in half along the scored line. Cut away any surplus using a plasterboard saw.
• Examine the fit:  After cutting the Plasterboard to size, ensure it fits snugly on the wall or ceiling. If additional trimming or sanding of the board's edges is required, do so now.

Plasterboard installation will go more smoothly if measured and cut precisely to fit snugly against the wall or ceiling.

Fitting The Plasterboard

Attach the Plasterboard to the surface (wall or ceiling) with nails or screws. Plasterboard needs to be installed correctly to ensure it is flush and stable.

It can be installed after the Plasterboard has been measured and cut to size. Plastering is installing a Plasterboard on a wall or ceiling using the right tools and methods. Plasterboard installation procedures are as follows:

• Apply adhesive: Using a notched trowel spread a thick layer of adhesive across the back of the Plasterboard. This will ensure the board has a strong grip on the ground.
• Placing the Plasterboard: Plasterboard should be pressed firmly into place after being positioned on the wall or ceiling. Check that it fits flush against the adjacent board or the wall/ceiling edge.
• Secure the Plasterboard: Plasterboard screws or nails should be used to fasten the board to the surface. Space the screws or nails every 0.5 inches (15.0 mm). Put the head of the screw or nail just below the Plasterboard's surface.
• Cut and shape to fit around obstacles: Prepare the wall for painting by cutting and fitting the Plasterboard around any pipes or corners. Cut the Plasterboard with a keyhole saw or a regular saw.
• Repeat the process: The process should be repeated with the remaining plasterboard sheets, with a gap of about 2 mm between each layer this time.

Plasterboard can be successfully attached to a wall or ceiling if it is fitted with care during installation.

Finishing The Surface

After the Plasterboard has been set up, the surface can be finished to make it uniform and smooth. For example, jointing, taping, and sanding.

Plasterboard needs to have its surface finished to look smooth and polished. To prepare a surface for painting or wallpapering, you must first fill any gaps or holes caused by screws or nails, then sand it smoothly. Plasterboard surface finishing involves the following steps:

• Fill the gaps: Apply the joint compound with a wide plastering knife to the spaces between the sheets of the Plasterboard. Coat the joint with the compound, making sure to get all of the crevices. Use the plastering knife to even out the compound, then wait until it dries.
• Fill the screw/nail holes: Fill the holes left by the screws and nails with the same jointing compound using a smaller filling knife. Make sure the hole is completely covered by applying a small compound. Use the filling knife to make the compound as even as possible, then wait for it to dry.
• Sand the surface: Use a sanding block or sandpaper to achieve a uniform finish on the Plasterboard. Even out the screw/nail holes and the joints with some sandpaper. Avoid tearing the Plasterboard by sanding carefully.
• Apply a sealer: The Plasterboard must be sealed before it can be painted or wallpapered. Doing so protects the surface from absorbing moisture and improve the paint or wallpaper's ability to stick to it.
• The wall should be painted or wallpapered: Paint or wallpaper can be applied after the sealer has dried. Always refer to the manual and employ the correct equipment and methods.

Plasterboard's surface needs to be finished properly before it can be painted or wallpapered so that it looks finished and professional.
