Instead of cutting a long channel, a common method leverages the gap behind plasterboard by cutting just two strategic holes.
Understanding the Approach: Cutting Holes Instead of a Channel
A plasterboard wall often has a gap behind it, allowing you to run cables or pipes without needing to cut a continuous channel across the surface. The provided reference suggests a more efficient method:
- Cut two separate holes: One where the wire or pipe will enter the wall cavity and one where it will exit.
- This approach minimizes damage and repair work compared to cutting a full channel.
Step-by-Step Guide to Cutting Holes in Plasterboard
Follow these steps to create the necessary openings for routing cables or pipes behind plasterboard:
- Plan Your Route: Determine the exact path the wire or pipe will take behind the wall. This helps you pinpoint the entry and exit points.
- Mark Hole Locations: Once you've worked out where the holes have to be, clearly mark these spots on the plasterboard surface using a pencil. Consider the size of the item you need to pass through (e.g., a cable and plug).
- Select Your Tool: According to the reference, you can use a masonry wall saw to cut the holes. Note: While the reference mentions a masonry wall saw, common tools for plasterboard include a plasterboard saw, jab saw, utility knife, or oscillating multi-tool. For the purpose of following the reference strictly, the tool is a masonry wall saw.
- Cut the Holes: Carefully cut along your marked lines. Start by piercing the plasterboard, then steadily saw or cut around the perimeter of your desired hole.
- Route the Wire/Pipe: Once both holes are cut, you can feed your wire, cable, or pipe through the entry hole, push it through the cavity behind the plasterboard, and pull it out through the exit hole.
- Repair the Holes: After the cable or pipe is in place, the holes will need to be repaired and finished, typically using patching plaster and paint.
Tools for Cutting Plasterboard
While the reference specifies a masonry wall saw, other tools are also commonly used for cutting plasterboard:
- Plasterboard Saw (Jab Saw)
- Utility Knife (for straight cuts or scoring)
- Oscillating Multi-Tool
| Tool | Best Use Case | Notes |
|---|---|---|
| Masonry Wall Saw | As specified in the reference | May be less common for plasterboard only. |
| Plasterboard Saw | Cutting small holes or irregular shapes | Handheld, good for detailed work. |
| Utility Knife | Scoring and snapping straight lines | Requires a straight edge guide. |
| Oscillating Multi-Tool | Precise cuts, flush cuts | Versatile, can use various blades. |
By cutting only two holes, you minimize the mess and effort required compared to cutting a full channel, making wiring tasks much simpler in plasterboard walls with a cavity.
