Plastering mistakes

1. Choosing the Wrong Type of Plasterboard

Selecting the right type of plasterboard is crucial for the success of your project. Plasterboard comes in various types, including standard, moisture-resistant, and fire-rated options.

Using the wrong type can lead to problems such as mould growth in wet areas or insufficient fire protection in crucial parts of the building.

Always match the plasterboard to the room’s requirements, especially in bathrooms and kitchens where moisture levels are high.

2. Improper Measuring and Cutting

Accurate measurements and precise cutting are essential to ensure a perfect fit and seamless finish. Errors in this stage can result in gaps, uneven joints, and wasted materials.

Use a reliable measuring tape and a straight edge to mark your cuts.

Always double-check your measurements before cutting to avoid costly mistakes. For intricate cuts around fixtures, take your time to measure multiple times.

3. Plastering Mistakes: Incorrect Attachment

Securing plasterboard to the framing correctly is vital to avoid future problems like cracks and warping. Use the appropriate screws and spacing as recommended by the manufacturer.

Typically, screws should be spaced every 200mm along the edges and every 300mm in the middle of the sheet.

Over-tightening screws can damage the plasterboard, while under-tightening can lead to loose panels.

4. Poor Finishing Techniques

A smooth, professional finish requires proper jointing and sanding. Skipping steps or using poor techniques can result in visible seams and an uneven surface. Apply joint compound to all seams and screw holes, then tape over the seams.

Once dry, sand the surface until smooth. For a polished look, repeat the process of applying compound and sanding at least two to three times.

Dust management is also important; use a vacuum sander to minimise dust spread.

5. Using Inappropriate Tools

Using the correct tools is essential for a professional finish. Invest in quality tools like a T-square for measuring, a utility knife for cutting, and a power drill for securing screws.

Poor-quality tools can result in inaccurate cuts, improperly secured plasterboard, and a substandard finish.

Good tools not only improve the quality of your work but also make the job easier and more efficient.
