Natural stone is often used for countertops and tiling.Proper safety equipment and a wet saw are required to cut marble.The marble should be marked with a pencil where you want to make the cut.If you want to prevent chipping or breaking the slab, make a small slice on the backside and then cut the front of the marble.You can cut marble at home if you have the right tools and preparation.
Step 1: Rent or purchase a wet saw.
The diamond blade ensures a smooth, clean cut, and a wet saw is the best option for cutting stone slabs.Renting may be more cost-effective than buying a saw if you only need to cut marble for a few jobs.Buying your own saw may be more convenient and economical if you are planning multiple home improvement jobs.It’s important to get the right wet saw.If you’re cutting marble that is more than 15 inches in diameter, a wet saw will not work.If you want the best saw for the job, ask an employee at the store.If you’re cutting a thin slab, you can use a circular saw with a diamond blade.A new wet saw can cost as much as $300.Renting wet saws costs about $35 a day or $100 a week.Diamond crystals on the blade of the saw help cut dense and strong items.
Step 2: Before you use the saw, read the instruction manual.
You may hurt yourself if you don’t know how to use the saw safely.The set-up instructions and safety warnings on your particular model are slightly different.You can easily and safely cut the marble slab if you know the ins and outs of your model.
Step 3: The saw needs to be connected to a water supply.
The blade must remain wet in order to keep it cool.The marble can be cut wrong if the blade gets too hot.Depending on your model, you may have to fill up the water tank or connect the saw to a hose.You can find exact instructions on how to connect the water supply to the saw by reading your instructions.
Step 4: To prevent scratches, put the marble on a piece of foam.
A large piece of foam can be purchased from a craft supply store.As you cut your marble, use this to keep it flat.The marble gets scratched up when it’s moved across the platform of the saw.Attach the foam to the piece of plywood to make it easier to cut.Wait for the silicone to dry and attach the foam to the wood.If you want to cut at a comfortable level, you can lay the board on a saw horse.The marble should be the size of the foam.If you don’t have foam, use a non-abrasive surface.
Step 5: A mark on the marble is a guideline.
To mark the marble, use a pencil.If you want to make sure your line is drawn straight and accurately, use a ruler or tape measure.You can use the mark as a guideline while cutting it with the saw if it is easy to see.Alternatively, use a piece of tape to mark the marble.If you want to see the line on a dark piece of marble, this is a good idea.
Step 6: Water should be poured on the blade to lubricate it.
If you want the saw to be completely covered, fill a cup with water and pour it over the blade.The saw gets wet when you turn it on, so you don’t have to use a lot of water.
Step 7: Gloves will help you avoid cutting or slicing your hands.
The risk of cutting your fingers when slicing marble is mitigated by the use of safety gloves.For example, choose a pair of gloves made from canvas.
Step 8: Wearing safety earmuffs protects your ears from noise.
Before you use the saw, make sure you wear a pair of earmuffs.When the blade pierces through the marble, you will hear a loud noise.This noise may damage your hearing since you are standing very close to the saw.Earmuffs are worn when using a jackhammer or lawn mower.
Step 9: Flyaway pieces do not hurt you if you wear safety goggles.
One of the marble flyaways could end up in your eye if you use a wet saw.Make sure your eye is protected when you wear goggles.
Step 10: Don’t wear open-toed shoes or loose-fitting clothing.
If you wear baggy shirts or pants, the extra fabric could get caught in the saw and cause serious injury.Wear clothes that fit well.Keep your toes covered to prevent cuts from marble.For example, wear boots or sneakers.
Step 11: It’s a good idea to tie up long hair.
Long hair can get caught in a blade.Medium-length hair can be secured with a headband or an elastic hair tie.
Step 12: Align the piece of marble with the blade.
The correct side depends on your saw.The marble should be lined up with the right side of the blade.The slab may be cut too short if you use the wrong side.The blade cuts off about 8 in (0.32 cm), so make sure the piece you’re using is from your scrap side.If you want to know which side of the blade is correct, cut a piece of marble.Don’t let the marble move while you cut it.Soft pads are a good option for keeping your marble in place.
Step 13: The marble should be cut slowly and carefully.
The faster you move the marble through the blade, the more likely it is to break.Make your cuts slowly and let the machine do the work for you.Slow down if you start to see smoke.Pull the saw back a little before you begin the next small section.If you want to see how cutting at different speeds affects marble, make a few slices on a practice slab.
Step 14: Make a 1–3 in cut with the back of the marble facing up.
The marble should be cut with a piece of foam.Feed the marble slowly into the saw until you reach about 1–3 in, and then stop.The cut on the back of the marble is important.The end of your tile may break if you don’t do this.
Step 15: Continue cutting the rest of the marble slab after flipping it over.
Once you’ve made a small slice to the back, turn the slab over so the finished side faces upwards.Make your cut on the other side of the slab.To make sure your cut is clean and even, continue cutting the rest of the way through the slab.You don’t need to flip the marble and make 2 cuts if you’re cutting a very thin slab of marble.Use a diamond circular saw blade to make a single cut.
Step 16: After you make a cut, turn off your machine.
When not in use, keep your saw turned off.Whether you are working on a project or cutting marble, do this.When you are ready to make the next cut, turn it off.
Step 17: Dry or wet fine-grit sandpaper can be used to clean up jagged edges.
There may be jagged or sharp pieces on the edges since the diamond blade cuts the marble so smoothly.If you want to manually smoothen the edges, use wet or dry sandpaper.The first thing to do is to use 120-grit sandpaper to make the edges softer.You’ll scratch the marble if you use a coarse sandpaper.You can wet your sandpaper by holding it under your faucet.It may be easier to sand the stone surface with wet sandpaper.Try using an angle grinder to smoothen the marble.If you use a machine, you may have less control over the process.An orbital sander is an option.
Step 18: Take care of your workspace and wet saw.
Once you’re done, wipe down your surfaces with a clean rag and all-purpose cleaner, sweep your floor of any dust, shards, or remnants, and wipe your saw down after it’s cool.Keeping your workspace clean between uses helps prevent injury and keeps your items in good shape.Follow your instructions to drain your water tank.
Step 19: Add finishing touches with a grinder and diamond wheel.
You may want to make further adjustments once you’ve cut the marble into the shape you want.You can cut holes with a grinder.You can make sink cutouts.Bevelled edges can be created.
