Use construction adhesive on every treadApply a bead of construction adhesive to each stringer notch before setting the tread. This prevents squeaks and adds rigidity — a tube per stringer is cheap insurance against annoying creaks down the road.

This is a material estimate only. Actual lumber needs may vary based on cutting accuracy and wood quality. Always buy a spare stringer board in case of layout mistakes on the first cut.
