Nailing Furring Strips to Concrete Block A Step-by-Step Guide
Furring strips are thin strips of material, typically made of wood, that are utilized to create a level surface for attaching other materials or to provide a framework for insulation. When dealing with concrete block walls, furring strips can help to overcome the challenges posed by the existing surface, making it easier to install drywall, paneling, or other finishing materials. Nailing furring strips to concrete block can sound challenging, but with the right tools and techniques, it can be accomplished effectively. This article will guide you through the process of nailing furring strips to concrete block walls.
Tools and Materials Needed
Before getting started, it’s essential to gather the necessary tools and materials
1. Furring Strips Standard wooden furring strips (usually 1x3 or 1x4 inches). 2. Masonry Nails Choose nails specifically designed for concrete or masonry to ensure they hold securely. 3. Hammer or Pneumatic Nailer A hammer can work, but a pneumatic nailer with concrete nails makes the job easier. 4. Measuring Tape For accurate measurements and spacing. 5. Level To ensure that the furring strips are straight. 6. Stud Finder (optional) Useful if you want to locate any existing framing behind the concrete blocks. 7. Drill with Masonry Bit For pre-drilling holes if necessary. 8. Safety Gear Safety glasses and gloves to protect yourself while working.
Steps to Install Furring Strips
Step 1 Measure and Mark
Begin by measuring the height of the wall where you plan to install the furring strips. Typically, the strips should be installed vertically, spaced approximately 16 inches on center. Use your measuring tape to mark the positions of the strips along the concrete block wall using a pencil.
Step 2 Prepare the Furring Strips
Cut the furring strips to the desired height, allowing a slight allowance for your flooring if needed. Ensure all cuts are straight to provide an even surface for the next layer.
Step 3 Pre-drill Holes

For easier installation, especially when using masonry nails, pre-drill holes in the furring strips where you intend to place the nails
. If you are using a pneumatic nailer, this step can often be skipped.Step 4 Position the Furring Strips
Using a level, position the furring strip against the wall at your marked location. Ensure that it is level and adjust as needed. If necessary, you can secure the strip temporarily with a couple of screws to hold it in place while you nail it down.
Step 5 Nail the Furring Strips
If using a hammer, begin nailing at the top of the strip and work your way down, ensuring consistent spacing of nails (every 24 inches is commonly recommended). If using a pneumatic nailer, align the strips and fire the nails in at consistent intervals. Make sure to drive the nails deep enough so that the heads sit flush against the wood.
Step 6 Repeat
Continue this process by installing additional furring strips, ensuring they are level with one another. Use your measuring tape and level regularly to maintain uniform spacing.
Step 7 Inspect and Adjust
Once all furring strips are installed, conduct a thorough inspection to ensure that they are securely fastened and level. Make any adjustments as needed.
Conclusion
Nailing furring strips to concrete block walls is a straightforward process that can significantly improve the insulation, aesthetic, and functionality of a space. By following the steps outlined above and using the right tools, you'll create a solid framework for your wall finishing materials. Whether you’re preparing for drywall installation or simply seeking to improve your basement or garage, adding furring strips is an excellent way to enhance your project. Happy building!
