How To Cut Sandstone Pavers – Is it effective?

Deciding on the most effective way to cut and shape your sandstone pavers will depend on the following:

  • The amount of sandstone paving slabs that need to be cut
  • The width of the paving slab
  • The angles of the cuts needed
  • The tools needed

The most important question is how you will cut each of your paving slabs and this will be decided by the amount of cuts you need to make. Unless you need to make minor adjustments to a small number of the slabs then a hammer and chisel may suffice. In most cases though you will find that you will need a power tool with the most popular option being either an angle grinder or a masonry saw ( also known as a wet saw). If you want to cut down the pave stones, then you should know the äärekivi paigaldus hind along with the cutting. It will increase the knowledge about the installation and restoration of the stones. The working of the saw is better than the other methods at the place.

For most home projects where the amount of cuts needed are not excessive a 9” angle grinder will suffice

The bigger more industrial wet saws will only offer a real advantage if you have large amounts of straight

edges to cut to make and you may also find that it will be cheaper to buy a non-branded angle grinder that to hire a wet saw for a day. When cutting curved edges you will also find that an angle grinder allows more freedom to cut a curved angle as you want.

The best blades to use when cutting paving slabs

There are only 2 real options when it comes to choosing a blade , masonry or diamond blade.

Masonry blades: Are usually cheaper but they will wear down fast and the more it wears the smaller it gets making the cut depth smaller. You may find yourself having to flip the paver to eventually get the depth you need.

Diamond Blades: will cost more but they last longer without wearing as much making your cuts quicker with less effort. They’ll also stay sharper for longer again making your job easier.

Whichever blade you decide to use you will want to try and preserve the blade for as long as possible without having to replace it. To do this always cut in one direction, from left to right or vice versa. Running the blade back and forth won’t get the job done any faster; all it will do is wear your blades out.

Don’t put any extra pressure on the blade, you won’t get there any faster and just wear your blades out. Instead allow your angle grinder to do the work; your job is just guiding it while it cuts.


Measure twice cut once, is a saying we’ve all heard before, but we’ve heard it for a reason and that is it makes sense. Double checking your lines to make sure you’re right, means

You won’t waste paving slabs

You won’t waste time having to recut

You won’t waste your blade on cuts that are of no use.

Don’t forget the joint

This one has caught me a few times; if you have left an even joint between each of your paving slabs it’s important that you calculate this into the slabs that you need to cut and always measure twice and cut once! If you are cutting a piece that is 600mil wide and your joint is 15mil then you will need to measure and mark a line that is 585mil wide.


Once measured your lines can then be marked, you will want to use something that will give a clear definable line. Using a pencil means you will need to sharpen it every 5 minutes. Instead try a steal nail or a piece of flint like slate. Now using a straight edge use a ruler or the straight edge of a hand saw Cutting sandstone pavers

Now that you’ve ready to start cutting the first thing to think about is how to position the paving slab.

Flat: Laying your paving slab either on a bench or on the ground will make sure you have a plumb cut. Positioning the slab on a bench will allow you to clamp and secure the paving slabs in the safest position possible.

Angled: if you are a little more experienced in using an angle grinder you can the lay each of the pavers on a slight angle and then cutting straight down with the angle grinder will leave you with a slight undercut. Having this undercut will make it easier to lay each of the pavers. Having this undercut means that you will spend less time straightening and levelling off any jagged edges. Instead you are left with a neatly cut straight edges that will hide any unsightly braking points.

Making the first cut: Making the first cut is the most important but is also the hardest. Once the first guide line is made you will just need to the angle grinder through each subsequent cut until you are between a half and 2/3rds of the way through the paving stone.

If you are having difficulty making the first cut straight you can use a piece if steel to help guide the angle grinder while it cuts Breaking after a cut

Once you have made a cut to the required depth you can now make the final break. Now using your lump hammer firmly hit the paver on the opposite side of your cut. The force you exert through the use of the hammer will then look for the point of least resistance and this will be through the previous cut you have made. If you cut was deep enough you will end with the perfect break almost every time. And if your initial cut used the undercut method the time you will need to finish the stone will be minimal.

The method above is most effective with straight lines, if you are cutting curved edges it is wise to take the time to fully cut through each end of the curved end while cutting still cutting the centre at least half way through.

  • Safety
  • Cutting sandstone pavers will create a lot of dust and shards of stone. You will need a
  • Dust mask
  • Goggles
  • Gloves

Hose pipe

To keep the dust that is created to a minimum run water over each of the pavers as you cut them. Soaking each of the paving stones before you cut them will also help to keep the dust down
