How to Frame on a Cinder Block

When constructing a house or large building project, it will be necessary to frame on a hard surface. The most typical scenario is framing on cinder blocks. Cinder blocks are sturdy, so they provide a good base for the framing process. The size of the structure and number of beams or columns being used will determine the duration of the framing process. Framing does not require the use of any power tools other than a simple drill, so the actual process is not overly burdensome.

Things You'll Need

• Sill plate
• Thin galvanized steel
• Bug shield
• Hammer
• Framing nails
• Drill
• Caulk
• Washers
• Nuts
• Wrench
• Screws
• Plywood
• Floor joists
• Rim joists

Instructions

1. Place the sill plate on top of the cinder blocks and drill a hole slightly larger than the cinder block's anchor bolts.

2. Lay the thin galvanized steel on top of the wall, and put the foam bug shield on top of it.

3. Connect the sill plate to the anchor bolts with nuts and washers, using the wrench.

4. Hammer the floor joists to the rim joists perpendicularly, using the framing nails, then attach the rim joist to the sill plate.

5. Glue the plywood to the floor and caulk the top of floor joist, using an adhesive. Screw plywood to the floor at perpendicular angles.
