Fitting Drywall Plasterboard and Plastering

Undertaking a home renovation or construction project often involves installing drywall plasterboard and applying plaster. Also known as gypsum board, drywall is a popular choice for walls and ceilings due to its ease of installation and smooth finish. Plastering adds a protective and decorative layer. This guide provides detailed instructions for fitting drywall plasterboard and plastering, ensuring a professional end result.

Section 1: Tools and Materials Required
Gather the following tools and materials before starting the installation:

• Drywall plasterboard sheets
• Drywall screws
• Screw gun or drill
• Tape measure
• Utility knife
• Straight edge or T-square
• Drywall saw
• Joint compound
• Drywall tape
• Plastering trowel
• Sandpaper or sanding sponge
• Primer and paint (optional)

Section 2: Preparing the Work Area

• Remove any existing wall coverings and inspect the studs or framing to ensure they are in good condition.
• Clean the area to remove any debris.
• If there are any electrical outlets or switches, turn off the power and remove the outlets.

Section 3: Fitting the Drywall Plasterboard

1. Measure the installation area and cut the plasterboard sheets to size using a utility knife and straight edge. A typical sheet size is 1200mm x 2400mm.
2. Position the plasterboard sheet against the studs so that the edges meet in the center of a stud.
3. Use drywall screws to secure the plasterboard to the studs, placing screws every 400mm along the studs and 10mm from the edge of the board.
4. Install the remaining plasterboard sheets, ensuring tight butt joints between the edges.

Section 4: Plastering

1. Apply a thin layer of joint compound over the seams and screw heads using a plastering trowel.
2. Place drywall tape over the seams, pressing it into the joint compound.
3. Apply another layer of joint compound over the tape, feathering the edges to blend with the surrounding area.
4. Allow the joint compound to dry completely, which may take up to 24 hours, and then lightly sand the surface for a smooth finish.
5. Apply a second coat of joint compound, feathering the edges even further.
6. Once the second coat is dry, sand the surface again and apply a third coat if necessary.
7. After the final coat dries, sand the surface to achieve a smooth finish.

Section 5: Finishing Touches

1. If desired, apply a coat of primer to the drywall.
2. After the primer dries, paint the drywall in your chosen color.
3. Reinstall any electrical outlets or switches.
4. Clean up any remaining dust or debris.

Conclusion
Fitting drywall plasterboard and plastering are achievable tasks with the right tools and some patience. Following this step-by-step guide will help you achieve a smooth and professional finish, enhancing the value and appearance of your home.
