How to dry line walls
Dry lining, also known as plasterboard or gypsum board, is a popular method for improving the insulation and appearance of walls. It involves attaching a layer of specially designed plasterboard to an existing wall, creating a smooth and even surface. Dry lining is a cost-effective alternative to traditional plastering, and it also provides additional benefits such as sound insulation and moisture resistance.
Before you start dry lining your walls, it’s important to gather all the necessary tools and materials. You will need plasterboard sheets, a utility knife, a measuring tape, a straight edge, a screw gun, screws, corner beads, jointing compound, sandpaper, an adhesive, and a taping knife. Make sure to wear protective gear such as safety glasses, dust masks, and gloves.
The first step in dry lining walls is to measure and cut the plasterboard sheets to fit the desired area. Use a utility knife and a straight edge to score the front of the plasterboard, then snap it along the score line. Once you have the correct size, use a screw gun to attach the plasterboard to the wall, making sure to leave a small gap between each sheet to allow for expansion. Secure the boards by placing screws along the edges and at regular intervals in the middle.
After all the plasterboard sheets are in place, you will need to fill in any gaps or joints between the boards. Apply a coat of jointing compound over the joints and corners, making sure to spread it evenly with a taping knife. Smooth out any excess compound and allow it to dry. Once dry, use sandpaper to smooth the surface, and apply another coat of compound if necessary. Finally, you can paint or decorate the plasterboard as desired to complete the dry lining process.
Preparing the Walls
Before starting the dry lining process, it is important to prepare the walls to ensure a smooth and successful installation. Here are some steps to follow:
|
Inspect the Walls: Before adding dry lining, carefully inspect the walls for any signs of dampness or structural issues. Address any problems before proceeding with the installation. |

Plan the Layout: Determine the layout of the dry lining sheets before installation. This will help ensure a balanced design and efficient use of materials. |
By properly preparing the walls, you can create a solid foundation for the dry lining installation, resulting in a professional and long-lasting finish.
Clearing the Area
Before you begin the process of dry lining your walls, it’s important to clear the area to ensure a smooth and efficient workflow. Here are a few steps to help you prepare:
1. Remove Furniture and Decorations
To avoid any damage or obstructions, start by removing any furniture, decorations, or other items from the room. This will provide you with the necessary space to work and prevent any unwanted accidents.
2. Protect the Floors
Next, cover the floors with a protective layer such as a drop cloth or plastic sheeting. This will help protect your floors from any dust, debris, or potential spills that may occur during the dry lining process.
Note: If you’re not able to remove furniture or belongings from the room, consider covering them with plastic sheets or moving them to the center of the room and covering them with drop cloths to minimize the risk of damage.
By clearing the area and preparing the space properly, you can create a clean and safe environment for the dry lining process.
Removing Wall Hangings
Before you begin the process of dry lining your walls, it’s important to remove any wall hangings or decorations that may be present. This will not only make the process easier, but it will also help to protect your wall hangings from damage.
Here are some steps to follow when removing wall hangings:
| Step 1: | Start by carefully removing any frames or pictures from the walls. Use a flathead screwdriver or a similar tool to pry the hanging hook away from the wall. Be sure to support the frame or picture as you remove it to avoid dropping and damaging it. |
| Step 2: | If you have any shelves or other wall-mounted decorations, remove them using a similar method. Use a screwdriver or appropriate tool to unscrew the brackets or supports from the wall. Again, be sure to support the item as you remove it. |
| Step 3: | For any adhesive-based wall hangings, such as stickers or decals, carefully peel them off the wall starting from one corner. Use a hairdryer on a low heat setting to soften the adhesive if necessary. Take your time and be gentle, especially if the wall has been freshly painted. |
| Step 4: | Once you have removed all wall hangings, inspect the walls for any remaining adhesive residue or marks. You can use a mild detergent mixed with water to clean the walls if needed. Be sure to let the walls fully dry before moving on to the dry-lining process. |
By following these steps, you can safely remove any wall hangings and prepare your walls for the dry-lining process.
Repairing the Walls
Before applying the dry lining to your walls, you should first ensure that any existing damage has been repaired. This will help create a smooth and even surface for the dry lining installation.
Here are some steps to follow when repairing the walls:
| 1. | Start by scraping off any loose or peeling paint, as well as any old wallpaper. Use a scraper or sandpaper to remove these imperfections. |
| 2. | If there are any holes or cracks in the walls, fill them in with a suitable filler compound. Apply the filler with a putty knife and smooth it out evenly. Allow the filler to dry completely before moving on. |
| 3. | If there are any large gaps or damaged areas, it may be necessary to use a patching plaster. Apply the plaster using a trowel, and follow the manufacturer’s instructions for drying times. |
| 4. | Once the repairs have dried, lightly sand the patched areas to create a smooth surface. This will help ensure that the dry lining adheres properly. |
| 5. | If necessary, apply a primer or sealer to the repaired areas. This will help improve the adhesion of the dry lining and create a more even finish. |
By properly repairing the walls before installing dry lining, you can ensure a high-quality and long-lasting result.
Filling Holes and Cracks
Before you start the process of dry lining your walls, it’s important to properly fill any holes and cracks in the existing wall surface. This will ensure a smooth and even finish once the dry lining is installed.
Materials Needed
To properly fill holes and cracks, you will need the following materials:
- A filler compound (such as a ready-mixed filler or a powder filler that can be mixed with water)
- A filling knife or scraper
- A sandpaper or sanding block
- A damp cloth or sponge
- A bucket or container for mixing the filler compound
Step-by-Step Process
Follow these steps to fill holes and cracks in your walls:
- Clean the area around the hole or crack with a damp cloth or sponge to remove any dirt or dust.
- If the hole or crack is deep, use a filling knife or scraper to partially fill it with the filler compound. Press the filler firmly into the hole or crack, ensuring that it is completely filled.
- For smaller holes or cracks, you can apply the filler compound directly with a filling knife or scraper.
- Smooth the surface of the filler compound using the filling knife or scraper, ensuring that it is flush with the rest of the wall.
- Allow the filler compound to dry completely. Check the manufacturer’s instructions for drying times.
- Once the filler is dry, use sandpaper or a sanding block to gently sand the surface of the compound until it is smooth and even with the surrounding wall.
- Wipe away any dust or debris with a damp cloth or sponge.
- Inspect the filled areas for any remaining imperfections. If necessary, repeat the filling and sanding process until the surface is completely smooth.
By properly filling holes and cracks in your walls before dry lining, you’ll create a solid and flawless base for the installation of dry lining materials.
Smoothing the Surface
After installing dry lining on your walls, it is important to smooth the surface to ensure a professional finish. Follow these steps to achieve a smooth and even surface:
-
Prepare the Surface
Before smoothing, remove any loose paint or wallpaper from the surface using a scraper or sander. Fill in any cracks or holes with filler and sand them down until they are smooth. Clean the surface to remove any dust or debris.
-
Apply the Skim Coat
Once the surface is prepared, mix a skim coat plaster according to the manufacturer’s instructions. Apply a thin layer of the plaster to the wall using a trowel, working in small, even strokes. Smooth the plaster using a plastering float or trowel, ensuring an even thickness across the entire wall.
-
Sand the Surface
Allow the skim coat to dry completely, following the recommended drying time. Once dry, sand the surface lightly with fine-grit sandpaper to remove any imperfections or unevenness. This will help create a smooth and level finish.
-
Prime and Paint
After sanding, wipe away any dust with a clean cloth. Apply a coat of primer to the newly smoothed surface, following the manufacturer’s instructions. Once the primer is dry, you are ready to paint your walls, creating a seamless and polished look.
Remember to take your time with each step and work diligently to ensure a smooth surface. By following these instructions and having patience, you can achieve professional results when dry lining walls.
Applying the Dry Lining
Once the walls have been prepared and the insulation has been installed, it’s time to apply the dry lining. Here are the steps to follow:
| Step | Procedure |
|---|---|
| 1 | Cut the plasterboard panels to the required size using a utility knife. Make sure the edges are clean and straight. |
| 2 | Apply adhesive to the back of the plasterboard panels using a notched trowel or a adhesive gun. Make sure to cover the entire surface evenly. |
| 3 | With the adhesive applied, position the plasterboard panel onto the wall, making sure it is flush and level. |
| 4 | Secure the plasterboard panel to the wall using drywall screws. Space the screws about every 200-250mm along the edges and 300-350mm on the rest of the panel. |
| 5 | Repeat steps 1-4 for each plasterboard panel, making sure to leave a small gap between them to allow for expansion. Use plasterboard adhesive as needed to fill any gaps. |
| 6 | Once all panels are installed, use joint tape to cover the seams between them. Apply a layer of joint compound over the tape using a trowel, smoothing it out as you go. |
| 7 | Allow the joint compound to dry completely, then sand it down lightly with fine sandpaper to achieve a smooth finish. |
| 8 | After sanding, apply a second layer of joint compound, feathering it out to blend with the surrounding surface. Repeat the drying and sanding process as needed to achieve the desired finish. |
| 9 | Once the joint compound is fully dry, the walls are ready for painting or wallpapering to complete the look of the room. |
By following these steps, you can successfully apply dry lining to your walls and enjoy the benefits of improved insulation and a clean, finished appearance.
