Cut a bunch of bricks in half. The half bricks will line the parameter of the porch deck. We line up the bricks along the parameter so as to count how many we need. Mortar will be added to hold them in place.
That circular saw with diamond chip blade cut all the brick, concrete, and tile in this porch project. You can get very straight cuts with it if you have strong hands and arms. We'll never rent a wet saw again.
How do they make diamond chip circular cutting blades so cheap? My blade does not have expansion slots so it warps sometimes if it gets very hot, but it works okay most of the time. If I get another one you can bet it will have expansion slots.
