We’re building an igloo! Wait, I mean an outdoor kitchen!

What happens here

Begin by marking the desired cut lines on the lightweight aerated concrete (AAC) block using a speed square and a pencil. Ensure the lines are straight and accurate for a clean cut. Once marked, position the block securely on a stable work surface, such as sawhorses. Using a Makita circular saw equipped with a suitable masonry or diamond blade, carefully cut along the marked lines. The cutting process will generate a significant amount of fine dust, so appropriate personal protective equipment is essential.

Goal: Precisely cut AAC blocks to size
