Whether you're a DIY enthusiast or a professional tradesperson, this guide will explore the steps and techniques to master gib fixing.

Grasping the Fundamentals

Before delving into any aspects of gib fixing, it’s essential to understand the basics. Gib boards come in various sizes and thicknesses, each suitable for respective purposes. Use a standard gib board with a 10mm thickness for wall and ceiling applications. Thicker boards, like 13mm or 16mm, are typically employed in areas that require soundproofing or impact resistance.

Choosing the size and thickness of the gib board based on your project’s requirements is essential. Also, consider the conditions that could impact how well the gib board performs, like changes in humidity and temperature. If you’re unsure, consult one of many reputed gib fixers in Auckland to better understand.

Tools and Supplies

You need the right tools and supplies to become skilled at fixing gib boards. According to well-known gib fixers, here’s a list of items you’ll need:

  • Gib board: As mentioned before, select the size and thickness based on your project requirements.
  • Stud finder: This tool helps you locate wall studs or joists, which are crucial for securely attaching the gib board.
  • Screws: Use high-quality screws designed explicitly for gib fixing. These screws should be 5mm longer than the thickness of the gib board to ensure a secure hold.
  • Drill or screwdriver: These tools drive the screws into the gib board.
  • Utility knife: You’ll need this tool for cutting the gib board to fit around obstacles, like windows, doors, or electrical outlets.
  • Compound and tape: These products fill gaps between gib boards and achieve a seamless finish.
  • Sandpaper: It helps smooth out the joint compound after it has dried.

Preparing the Surface

Before installing the gib board, it’s essential to ensure you properly prepare the surface, which means removing any existing wallpaper, paint, or loose plaster. Ensure the surface is clean, dry, and free from dust or debris. Also, check for any issues or damage you must address before fixing the gib.

Marking the Studs

Studs are metal supports that form the framework of a wall or ceiling. It’s essential to accurately locate and mark the studs for attaching the gib board. To find them, you can use a stud finder or tap lightly on the wall until you hear the sound of a hollow one. Once you’ve located the studs, mark their position on the wall or ceiling using a pencil or tape.

Cutting and Installing Gib Board

Measure the dimensions of the wall or ceiling where you intend to install the gib board. Use a utility knife to cut it to fit correctly. Ensure that your cuts are clean and straight for a smooth finish. Starting from one corner of the room, place the gib board against either wall or ceiling while ensuring its edge aligns with your stud. To attach the gib board to the studs, use screws. Place them approximately every 200mm along the edges. Keep them at least 300mm apart in the center.

Be careful not to tighten and damage the gib board while using a screwdriver or drill to drive the screws. Continue this procedure for the remaining gib boards, ensuring a fit between boards. Leave a 2-3mm gap between each board to accommodate expansion and contraction.

Taping and Jointing 

After installing the gib boards, it’s time for the next step. Apply compound to fill the seams between the boards, ensuring all gaps are covered. Then, carefully place self-tape over the wet joint compound, pressing it firmly into position and smoothing out any bubbles or wrinkles. Allow the joint compound to dry completely before proceeding, which typically takes 24 to 48 hours, depending on humidity levels.

Dry and lightly sand down the compound for a smooth and seamless finish. Repeat this taping and jointing process if additional compound layers are needed, thoroughly drying each layer before moving on to the next one.

Adding the Final Touches

Once the joint compound has dried and you’ve smoothed it with sandpaper, it’s time for the finishing touches. Use compound to fill in any remaining imperfections or gaps and sand again if necessary. When you’re satisfied with the smoothness, you can move on to priming and painting the gib board to complete your project.


You can become skilled at fixing gibs by following these steps and techniques to achieve professional results. Remember that practice is vital, so be bold, start with smaller projects, and gradually tackle more complex ones. With time and dedication, you’ll soon become an expert in gib fixing.
