Step 1: Prepare the Surface
Before installing insulated plasterboard, it’s important to prepare the surface to ensure a smooth and secure installation. Follow these steps:
Inspect the wall
Start by inspecting the wall to identify any damage, cracks, or uneven areas. Fix any noticeable issues with the wall before proceeding with the installation.
Remove any existing wall coverings
If there are any existing wall coverings, such as wallpaper or paint, remove them to expose the bare surface. This will help the insulated plasterboard adhere better to the wall.
Pro tip: Use a scraper or putty knife to remove stubborn wallpaper or hardened paint.
Clean the surface
Thoroughly clean the wall surface to remove dust, dirt, and any other debris. Use a brush or a vacuum cleaner to ensure a clean working area.
Note: A clean surface is crucial for achieving optimal adhesion between the wall and the insulated plasterboard.
Remove old plaster or wallpaper
Before installing insulated plasterboard, it’s important to remove any old plaster or wallpaper from the walls. This step is necessary to ensure a smooth and even surface for the new insulated plasterboard to be attached to.
To remove old plaster, you will need a hammer and chisel. Starting at the top corner of the wall, gently tap the chisel behind the plaster and pry it away from the wall. Continue working your way along the wall, removing the plaster layer by layer. Be careful not to use excessive force, as this can damage the underlying structure.
If the walls are covered with wallpaper, you will need a wallpaper scorer. This tool has small blades that make small cuts in the wallpaper, allowing water or a wallpaper stripping solution to penetrate and loosen the adhesive. Score the entire surface of the wallpaper, taking care not to press too hard and damage the underlying wall.
After scoring the wallpaper, apply a wallpaper stripping solution or warm water mixed with wallpaper remover to the surface. Allow the solution to soak into the wallpaper for the recommended amount of time specified on the product label.
Once the wallpaper has loosened, use a wallpaper scraper or putty knife to gently lift and remove the wallpaper from the wall. Work in small sections to avoid damaging the wall surface. If there are stubborn areas that refuse to come off, reapply the wallpaper stripping solution and repeat the process until all the wallpaper has been successfully removed.
After removing the old plaster or wallpaper, be sure to thoroughly clean the walls with a mild detergent and water. This will remove any remaining adhesive or dust and provide a clean surface for the installation of the insulated plasterboard.
Repair any damaged areas
Before installing insulated plasterboard, it is important to inspect the existing walls for any damaged areas. This includes cracks, holes, or any other imperfections that could compromise the integrity of the plasterboard installation.
Start by cleaning the damaged area to remove any loose debris or dust. Use a scraper or sandpaper to smooth out any rough edges or surfaces. Make sure to wear appropriate safety gear, such as gloves and goggles, when working with plasterboard or repair materials.
Crack repair
If you notice any cracks on the wall, they will need to be repaired before installing the insulated plasterboard. Use a scraper or utility knife to widen the crack, creating a V-shaped groove. This will help maximize the bonding surface for the filler material.
Next, use a filler compound specifically designed for crack repair. Apply the filler using a putty knife, making sure to press it into the groove firmly. Smooth out the surface with the putty knife and allow it to dry completely. Once dry, sand the surface until it is smooth and flush with the surrounding wall.
Hole repair
If you have any holes in the wall, they will also need to be repaired. Small holes can be filled with a ready-mixed filler compound. Use a putty knife to scoop up a small amount of filler and press it into the hole. Smooth out the surface and allow it to dry before sanding it down.
For larger holes, it is best to use a patching plaster or a pre-made plasterboard patch. Cut the patch to fit the size of the hole, making sure there is a slight overlap around the edges. Apply a thin layer of patching plaster or joint compound to the back of the patch and press it firmly into the hole. Smooth out the surface with a putty knife and allow it to dry before sanding it down.
Once all damaged areas have been properly repaired and the surfaces have been sanded down, you can proceed with the installation of the insulated plasterboard.
Clean the surface thoroughly
