But larger is not always better when builders are constructing a home or adding a room addition. Then attach the sister joist using three 16d common nails driven every 16 in. Previous step next step.

Using the wall as a guide to keep the first joist straight use the nail gun to secure the first joist at the end of the bearer near the wall. Now you re ready to secure all the joists to the bearers. A plywood subfloor will bridge any minor waves in the existing floor and leveling compound would help too. Fix the first joist.

Driving 16d common nails in old hard wood is difficult.
