Materials And Equipment For Plastering
Before you begin your plastering journey, you must familiarise yourself with the tools and materials required for the job. Here’s a comprehensive list of must-have tools for successful plaster installation:
1. Hammer
A reliable hammer is a fundamental tool for any plastering project. There are two types of hammers commonly used in plastering:
- Claw Hammer: Useful for removing sections of plaster and reattaching or removing loose lath.
- Drywall Hammer: With its curved head and hatchet-like end, this tool is ideal for cutting through drywall and plaster sections.
2. Handsaw
A sharp handsaw is indispensable for projects involving wood lath. It’s also beneficial for removing pieces of old wallboard when preparing for new installations or refurbishment work.
3. Spackle Knife
A spackle knife is crucial for smoothing cracks and uneven areas before applying new plaster. It ensures that the final result is polished and free of bumps or chips.
4. Bucket
A durable five-gallon bucket is necessary for mixing plaster. Ensure it’s strong enough to withstand repeated use, as plaster is heavy, especially when mixed with water.
5. Utility Knife
A sharp utility knife is needed to open plaster mix bags, score walls, and cut drywall patches. Keeping the blade sharp enhances both safety and efficiency.
6. Paddle Mixer
A paddle mixer is a drill attachment that simplifies mixing plaster. It helps blend wet and dry ingredients swiftly, ensuring a consistent mixture for your project.
7. Bucket Trowel
A bucket trowel with a slanted handle and wide working surface helps scoop plaster from the bucket without making a mess. It’s ideal for breaking up dry ingredients before mixing.
8. Hawk
A plaster hawk is a flat, rectangular tool that holds wet plaster. It helps transport the plaster to the wall more efficiently, making it easier to load your trowel evenly.
9. Trowel
A 12-inch rectangular trowel is the key tool for applying plaster to walls. A well-maintained trowel with sanded edges will leave fewer lines and create a smoother finish.
10. Paint Brush
A 4-inch heavy-bristled paintbrush is used for smoothing rough areas during the plastering process. It’s also useful for cleaning tools like the mixing paddle and trowel.
11. Plumb Bob
A plumb bob checks the vertical level of walls, ensuring that the surface is aligned correctly.
12. Floating Rule
This tool ensures the surface is level between plaster applications, providing a professional finish.
13. Sponge
A damp square sponge is used to smooth the plastered surface, evening out the texture for a flawless result.
14. Tube Level
A tube level is a clear water-filled tube used to ensure that the upper portion of the plastered surface is even and parallel.
15. Spirit Level
A spirit level ensures that your walls are straight and balanced, a vital tool for achieving a professional finish.
Step-By-Step Instructions For Plastering A Wall Like A Pro
Now that you have the necessary tools let’s walk through the process of plastering a wall step by step.
Step 1: Preparation
Before you begin plastering, it’s important to prepare the area. Follow these steps:
- Lay down a dust sheet to protect your floors from plaster dust and debris.
- Ensure the wall is dust-free, especially if plastering an older surface. Remove any loose debris and dirt.
- Apply screen tape to any cracks or holes in the wall. This helps ensure that the plaster adheres evenly and prevents cracks from reappearing.
Step 2: Paint The Walls With PVA
Apply a PVA solution to the walls first to ensure the plaster adheres well. PVA helps regulate the drying process, allowing the plaster to set evenly.
- Mix one part PVA with four parts water and apply it to the wall using a roller or brush.
- Ensure even coverage and wait for the PVA to dry before applying the plaster.
Step 3: Mix The Plaster
Follow the manufacturer’s instructions to mix the plaster correctly.
- Wear a dust mask when handling dry plaster powder.
- Pour water into a container and add plaster while whisking until it reaches a smooth, custard-like consistency.
Step 4: Apply The First Coat Of Plaster
It’s time to apply the first coat with the plaster mixed and the walls prepared.
- Scoop the plaster and apply it to the walls using a hawk board and trowel.
- Start from the lower left corner and work your way up, using upward strokes to create an even surface.
- Apply minimal plaster and use heavy pressure on the float to smooth out the surface and prevent flaking.
Step 5: Smooth And Skim The Wall
After the first coat dries for about 20 minutes, use a trowel to smooth out any bumps or ridges.
- Smooth the edges of the wall and focus on difficult areas like the corners and along the ceiling.
Step 6: Scrape The Wall
Before applying the second coat, lightly scrape the surface with a devilling float. A regular kitchen fork will do the job if you don’t have a devilling float.
Step 7: Apply The Second Coat Of Plaster
Mix the plaster slightly thinner than before for the second and final coat and apply a 2 mm layer to the wall.
- Work methodically, ensuring that the plaster is even across the entire surface.
Step 8: Polish The Plaster
Once the second coat has dried slightly, it’s time to polish the plaster for a smooth finish.
- Spray the walls with water and use the trowel to smooth out imperfections, working from the edges toward the centre.
- Run a clean float along the surface to achieve the final polished look.
Step 9: Final Touches
Once the plaster is dry, sand down any rough spots and ensure the surface is smooth.
- If painting, apply an undercoat to seal the plaster before applying the top layer of paint.
- If wallpapering, apply an adhesive layer to ensure the wallpaper adheres properly.
Decorating With Paint And Paper
Now that your walls are plastered, you’re ready to decorate! If you plan to paint, apply an undercoat to seal the surface before applying the final colour. Use a high-quality adhesive to ensure a smooth and durable finish for wallpaper. Either way, your newly plastered walls will be the perfect canvas for your design vision.
