This type of plasterboard is ideal for walls and ceilings in homes, offices, and other buildings where noise reduction is necessary.

3. Fire-Resistant Plasterboard

Fire-resistant plasterboard is made with additives that make it resistant to fire. It is perfect for use in areas where fire protection is necessary, such as kitchens, garages, and other areas where there is a higher risk of fire. This type of plasterboard is available in various thicknesses and can provide up to 120 minutes of fire protection.

4. Thermal Plasterboard

Thermal plasterboard is designed to provide insulation to walls and ceilings. It is made of a core material that is sandwiched between two layers of standard plasterboard. This type of plasterboard is perfect for use in colder climates and can help reduce heating costs.

5. Corner Protection Plasterboard

Corner protection plasterboard is designed to protect the corners of walls and ceilings from damage. It is available in various thicknesses and can be used to reinforce corners that are prone to damage. This type of plasterboard is perfect for use in high-traffic areas, such as hallways and staircases.

The transition from traditional plaster to modern drywall or plasterboard has been a significant improvement in the building industry. Plaster was the primary material used for covering walls and ceilings before the introduction of drywall. However, plaster was a time-consuming and labor-intensive process that required expertly honed techniques and skills. The process involved several steps, including measuring, mixing, spreading, and polishing the plaster. The plaster also needed time to dry, which could take days or even weeks, depending on the thickness and the tightness of the area.

Putting Up Plasterboards: A Step-by-Step Guide

Before you start the installation process of drywall or plasterboard, make sure you have all the necessary building materials and tools. This includes the plasterboard itself, compound, screws, a drill, a saw, a measuring tape, a level, and safety gear such as gloves and goggles. It’s also important to ensure that the area where you’ll be installing the plasterboards is clean and free of any debris or obstacles.

Installing the Plasterboard

1. Measure the area where the plasterboard will be installed and cut the plasterboard to the required size using a saw.
2. Once the plasterboard is cut, apply a thin layer of compound to the back of the plasterboard.
3. Lift the plasterboard and mount it onto the wall or ceiling using screws.
4. Repeat the process until the entire area is covered with plasterboard.
5. Use a level to ensure that the plasterboard is straight and even.
6. If needed, cut small holes in the plasterboard to accommodate wires or pipes.

Finishing the Job

1. Once the plasterboard is mounted, apply a layer of compound to the seams between the plasterboards.
2. Use a trowel to spread the compound evenly and smoothly.
3. Allow the compound to dry completely before sanding it down to a polished finish.
4. Depending on the desired finish, you may need to apply multiple layers of compound and sand it down in between each layer.
5. If you’re looking to reduce noise, you can add insulation between the plasterboards before installation.
6. For a seamless exterior, you can use mineral or gypsum boards that are mounted using a slurry of paper and water.
7. Once the job is complete, you can enjoy the benefits of plasterboard such as its sound insulation, affordability, and easy installation process.

Expert Tips

  • Experienced professionals may use different techniques and methods depending on the job and the type of plasterboard being used.
