While answering, we shall also go through the buyer’s guide in brief so you know how to arrive at an easy decision.

Which saw blade to use for composite decking?

Any circular saw blade that has 40 teeth or more will do the job well. The number of teeth on the blade is a crucial factor since it leads to better accuracy of the cut and the speed with which they are made. Having a blade with fewer teeth may cut faster but will result in rough finishes.

What else will I need other than blades when cutting composite decking?

Other than the blades, you will require a tape measure for easy measurement, a pencil, or chalk to mark the cut-away, and, lastly, and most importantly, eye and ear protection. If you’re using premium cutting blades you may not have to wear eye protection since they produce minimal debris but it is advised nevertheless to be on the safer side.

How long does it normally take to cut composite decking?

The answer to this depends on multiple factors. First, one has to take into consideration the complexity of the deck design. Secondly, one has to consider the blades that are being used. Thirdly, one has to take into account the level of expertise of the user.
