Though there are multiple methods of cutting concrete siding, you still need some special tools at your disposal. You can either use shears, the circular saw with an appropriate blade or even a shock utility knife in some cases. The cleanest, safest and most efficient way of cutting concrete siding is by using a carbide bladed utility knife
Tools and Materials Needed:
- Measuring tape
- Utility knife
Step 1 – Take Measurements
Take the measurements you need to cut the concrete. Make sure you double check them before starting any cutting. Mark the cutting line using pencil on the back of the concrete siding. To do this, use a straightedge to draw a line across the entire width of the sighting, starting from the market the edge.
Step 2 – Score a Line
Using the utility knife with carbide blade on it, score a line along the guideline that you marked. Ensuring that the surfaces flat unstable, place the cutting line over the edge of the workspace. You should now be able to snap the plank along the side.
Step 3 – Use the Rasp
Use a heavy duty metal rasp to smooth the edge along the cut line.
