Preparation for Cutting Sandstone
A professional prep is important as you can prevent material wastage, you get smooth edges to improve water drainage and aesthetic finishes, and also you get accurate cuts that simplify laying sandstone paving with straight joints.
- Selecting the Right Blade: Diamond blades are recommended for natural stones. A continuous rim ensures cleaner cuts.
- Safety: Use Ear and eye protection, gloves, and dust masks.
- Wet Cutting: For grinders or circular saws, wet the cutting line to reduce dust and cooling.
- Solid and Stable Base: Stabilise the slabs on an even and rigid surface like plywood or saw sawhorse.
- Mark Your Cuts: Use chalk or a pencil to mark before you cut.
Measuring and Marking
When it comes to how to cut a paving slab, follow the rule of thumb, “measure twice and cut once,” for your paving project.
- Plan the desired layout by placing your slabs on the visualised spacing.
- Measure precisely and also account for the joint spacing of 5mm to 10mm.
- Use a straight edge by snapping chalk lines for long cuts.
- Use adjustable-angle squares for precise cuts.
Methods of Cutting Sandstone Slabs
How do you cut sandstone slabs? There are a number of methods you can use when you ask how to cut Indian Sandstone. The best way to cut Indian sandstone slabs depends on the project you are tackling.
Wet Saw Cutting
This method is used for precise and straight cuts on large slabs.
- Align the slabs with your mark.
- Start cutting slowly and steadily. Do not push aggressively.
- Rinse the slab between cuts to clear debris.
Curricular Saw Technique
It is used for straight cuts when a wet saw is not available. It also works for smaller slab sizes.
- Use a diamond masonry blade.
- Cut shallow passes like 5 to 10mm depth before you start full-depth cuts.
- To maintain line accuracy, keep the straight edge guide
Angle Grinder for Curves
It is beneficial for curves, notches, and cutouts. In short, it is perfect for custom shapes in tiles or slabs.
- First, mark the curves clearly.
- Use a lighter granite blade.
- Make successive shallow cuts.
- Tap with a hammer and bolster if needed.
- Smooth the edges with a rubbing stone or a fine grinding disc.
Block Chisel and Hammer
If you are cutting paving slabs by hand, this method works best for rough straight cuts or breaking of edges. It is ideal for rustic finishes or thick stones.
- Score your slab edges on both sides.
- Tap your chisel gently along the score line.
Edge Finishing and Rubbing
When you cut your natural stones, the edges can be rough. Use edge finishing techniques like:
- Rubbing: Polish the sharp flares of the stone and chamfer edges.
- Angle Grinder: Light feathering for a softer cut finish.
- Sandpaper Pads: Progress from 80 to 120 grit to smooth the edges and blend in cuts.
Tips for Clean Break Lines
If you would like to have clean break lines, follow the tips below:
- Ensure that your blade choice is correct and you go with a slow feed speed.
- Keep your cuts wet. If you are cutting large stone slabs outside, use a garden hose.
- Choose a stable platform and support the slab to prevent vibrations.
- Let the blades do their work. Do not force cuts as it can crack your slab.
Common Mistakes to Avoid
Avoid the following mistakes during paving stone cutting, in order to have a clean outdoor space you can enjoy for years without worrying.
- Putting too much pressure can cause chipping or irregular edges.
- Using incorrect blade types that can chip your stone. The blades must have a continuous rim.
- Cutting sandstone slabs dry is a no-no, as it generates excessive dust and heats the blade.
- Skipping safety can be life-threatening. Eye, ear, and lung protection is non-negotiable.
Working with Angled Cuts and Corners
It is complicated to cut paving slabs for the angled edges or corners. Do this for precise cuts, especially if you are laying Sandstone slabs like Kandla Grey or Raj Green and want to avoid expensive mistakes:
- Template the odd shapes with cardboard first.
- Snap chalk lines along the inside cuts.
- Start with shallow passes before you make deep cuts.
- Use an angle grinder or block splitter to finish corners accurately.
Post-Cutting Maintenance
After you cut your slabs, do this:
- Let your slabs dry fully before sealing them.
- Clean all the dust and grit before laying them in the decided layout.
- Smooth the edges with rubbing stones.
- Seal the sandstone pavement within 2 to 4 weeks to protect it from permanent staining and weathering.
Eco-Friendly Disposal
After cutting the sandstone paving, you need to take care of the pieces left behind.
- Collect the stone cut-offs for garden use.
- Recycle the unused pieces when available.
- Sweep your area thoroughly in order to avoid onsite hazards and accidents.
