Lay the boards out in the position you want them installed. The boards should be placed parallel, two points apart.
Space each board 1/4 inch a part. This allows for proper water drainage along with wood swelling and expansion due to climate changes.
Place each 2-1/4 #7 trim-head screws into the proper bolts and fasten them.
Adjust the depth of the carbide-tipped saw's blade to the thickness of the boards.
Mark the carbide-tipped saw's cut with a piece of white chalk.
Scrape the edges of the positioned deck boards.
