How Do You Cut High Impact Drywall?

Like cutting regular drywall boards, the first step to cutting high-impact drywall is to take safety measures and plan your cut.

However, high-impact gypsum drywall boards are unlike regular drywall boards. High-impact drywall panel boards are heavy and wide; cutting them requires more skill. 

Hence, the cutting technique for high-impact drywall isn’t as straightforward as cutting the regular drywall board.

In cutting high-impact drywall boards, a pro tip is first to cut the front side of the board. The backside of the drywall has a paper cover that doesn’t allow a smooth cut. 

Also, the backside of the high-impact drywall panel is quite brittle and crumbles when applying cutting tension.

Therefore, ensure to mark and cut the front side of the drywall board before proceeding to do the same with the backside. 

Another pro tip in cutting high-impact drywall to access plumbing is that cutting always begins from the side edges. 

It will help if you begin your cut from the visible edge of the drywall board for a clean, smooth cut. 

Plus, a cut from the side walls makes the work appear neat; it is a lot less damaging than cutting from the surface of the drywall. 

The steps below will come in handy in cutting high-impact drywall boards.

  • The easiest way to cut high-impact drywall is by scoring the panel with a cutter or utility knife using a straight edge as a guide. 
  • For large panels, lay them on an even, smooth surface. 
  • Cut the drywall panel from the side edges according to your markings and outline. 
  • Note that the cut must just be enough to plunge through the paper cover of the drywall on the other side.
  • With a correct cut, a little pressure will cause the panel to break through the cut line.
