How to Cut a Concrete Patio

Cutting a concrete patio can be accomplished by using several techniques. The quickest and most practical way is by using a gas-powered concrete saw. These saws can be costly to purchase, but are available for rent at do-it-yourself stores. The rental saws will come conveniently equipped with a blade for cutting concrete. Another technique for cutting concrete is to use an abrasive masonry blade or diamond blade in a circular saw. These blades are best for small jobs or when you need to cut concrete at an angle.

Things You'll Need

• Concrete saw
• Abrasive masonry blade or diamond blade
• Safety goggles
• Safety gloves

Instructions

1. Measure and place lines at each end of the concrete to determine where cuts are needed. Use a chalk box to snap straight lines, ensuring straight cuts.

2. Prep the concrete saw per manufacturer directions. This may include checking the oil, filling the saw with gas, and checking the saw and blade for any defects that may cause damage to the saw or harm to the operator. Some concrete saws require water for cooling purposes and will include a water hose hook-up.

3. Start the saw and slowly start a cut on the line. Hold the saw parallel with the cut so that the blade does not bind. Using this technique will also ensure a straight cut.

4. Follow the line in a smooth, controlled fashion. For smaller cuts, you can also use a skill saw with a masonry blade to slice through concrete. This is a much slower way of cutting concrete, but it is a great technique for cutting angles for edging purposes.
