How to build an interior wall on concrete.
The tops of cement block walls are typically capped by applying a layer of mortar embedding metal reinforcement strips then covering the wall with solid concrete cap blocks.
Use an impact driver to drive a 3 tapcon screw through the wood and into the floor.
Insert shims between the joists and wall as necessary to make the wall fit snugly.
Be sure to wear safety goggles when hammering masonry nails into concrete.
Make sure joints between cap blocks are filled with mortar and smoothed with the finishing tool.
Measure out from that nail to where the other face of your wall will be and place another nail.
Walls are built from the ground up.
Cut pressure treated 2 x 4 boards to length and lay them along the chalk line.
Thread and hand tighten a nut onto each anchor.
Align the wall with the chalk snap lines that indicates its position.
Slide a washer over each anchor.

Space attachments every 12 inches using two at a time.
Cut four or five two by four blocks each perhaps 10 to 12 inches long and insert them between the end studs on.
Other nails have a thick shank that sometimes has spiral ridges for improved holding power.
