How to cut plasterboard
Plasterboard is a versatile and flexible product that can be used in many construction projects from DIY to large industrial jobs. To cut plasterboard you can use an ordinary saw but a saw with fine teeth would be best to ensure a clean cut. Sawing plasterboard is the best way to cut the product but be prepared for the chosen tool to get blunt and have a spare to hand!
How to cut a straight line in plasterboard
- Measure the cut you need to make by working out where you need the line and drawing a rough guide with a pencil
- Hold a spirit level over the pencil marking on the plasterboard and push it down firmly so it stays in place
- Use this straight line to cut a shallow mark into the plasterboard with a Stanley knife or something similar
- Use this a guideline and cut the plasterboard all the way through with a saw
Check the progress of the cut regularly to ensure it’s staying where you’ve marked out.
How to cut a hole in plasterboard
- Measure the cut you need to make as accurately as you can
- Mark out the cut with a pencil
- Use a plasterboard hammer to bang 50mm inside one of the cut lines (this line will let you insert the blade of the saw to begin the cut so it’s a crucial step)
- Insert the saw into the 50mm deep line and begin cutting
Check the progress of the cut regularly to ensure it’s staying where you’ve marked out.
How to dispose of plasterboard
Plasterboard is classed as non-hazardous waste but it cannot be accepted at landfill sites. This is due to the gypsum inside. It reacts with bio-degradable products to emit a toxic gas! For large projects, you can get plasterboard-only skips and waste bags where all offcuts can go but for small projects and DIYers then contact a local waste collection or recycling company. Many of these companies will offer to collect plasterboard or you could take it to them.
Be sure to check in advance where you can dispose of excess plasterboard in your area, and always choose the option to recycle if you can.
