Marble is among the most beautiful and desired natural stones on the planet. There are several varieties with beautiful and distinctive veining. Natural stone is frequently utilized in house construction, especially countertops. This article should walk you through the process of cutting marble.

How to Cut Marble Countertop

Compared to stones like granite, this porous stone is considered a soft substance. Cutting marble is difficult for practically everyone, even seasoned DIYers. Not only is the job more challenging than usual, but any mistakes you make might destroy the pricey material. Patience and the right blade are essential to avoid harming the marble, which may be costly to repair. However, this seemingly impossible process becomes much more achievable with the correct equipment and a little know-how.

What You Need

A wet saw is the best tool for cutting marble.

Yet, wet saws are costly and specialized tools that most DIYers do not own. Hence, unless you rent or buy a wet saw, the circular saw is the next best tool to utilize.

  • Circular Saw
  • Diamond Blade
  • Grease Pencil
  • Measuring Tape
  • Masking Tape
  • Rigid Foam
  • Plywood and Sawhorses

Because you will be utilizing a standard circular saw rather than a wet saw, most experts advocate making your own water source.

To keep your saw cold, you will need the following:

  • Water Supply and Garden Hose
  • Clamps

Also, utilizing this procedure results in a little rough edge following the cut.

To smooth down the edge, you will need the following:

  • Sandpaper
  • Orbital Sander

Step I – Be Ready for the CutMarble Color

The first step is to place the marble slab. Place a sturdy sheet of plywood over two sawhorses to make a work table.

On top of the plywood, place a 2-inch-thick sheet of rigid foam. It provides a softer surface for the marble to sit on, preventing damage.

Place the marble slab carefully on top of the rigid foam.

Making your measurements is just as crucial as prepping the marble.

Then, use masking tape to tape off the edge that you will cut. It decreases the possibility of the cut marble edge becoming damaged.

Then, measure and make your markings on top of the masking tape.

Lastly, get your circular saw ready for the cut. Because you are not using a wet saw, aim the garden hose so that a trickle of water flows over the front of the blade.

Clamp the hose in place to keep it from moving during the cut.

Step II – Making the Cut

Run the circular saw slowly through the designated region. Don’t rush, and take your time. Ensure that the hose’s trickle of water continues to cool the front of the diamond blade throughout the cut.

Step III – Edge Sanding and Finishing

There is a significant probability that the cut you just made will have a rough edge.

Remove the masking tape and use your orbital sander to smooth off the edge. Work your way up from rougher to finer sandpaper.

Work your way up from 40-grit sandpaper to 400-grit sandpaper for the most excellent finish possible.

Bring In the Pros

It’s impossible to dispute that learning to cut marble countertop is scary.

Nevertheless, it’s actually rather simple with the correct tools and expertise. Even though a wet saw is an optimum tool for the job, the circular saw procedure mentioned above will get the work done securely and effectively.

Just keep your cuts to a few inches at most, and bring in the countertop installation pros for full-seam cuts to avoid cracking or shattering the marble slab.
