Nailing Furring Strips to Concrete Block A Comprehensive Guide
When it comes to building or renovating a space with concrete block walls, one often overlooked yet essential step is nailing furring strips to these surfaces. Furring strips serve as a framework for attaching drywall, insulation, or other materials. They are particularly useful in creating a level surface and helping to enhance insulation or aesthetic features in a room. Here's a step-by-step guide to nailing furring strips to concrete block.
Understanding Furring Strips
Furring strips are thin strips of wood or metal used to create a level framework against a wall, ceiling, or floor. In the case of concrete block walls, furring strips provide a surface to which you can attach drywall and other finishing materials.
Tools and Materials Needed
To get started, you’ll need several tools and materials - Furring strips (typically 1x3 or 1x4 boards) - Concrete nails or masonry screws - A hammer or drill - Level - Tape measure - Chalk line - Safety goggles
Preparing the Wall
Before you can attach the furring strips, make sure the concrete block wall is clean and free of debris. If there are any loose pieces of mortar, remove them to ensure a smooth surface. This will help the furring strips sit flush against the wall.
Measuring and Marking

Using your tape measure, determine the spacing for the furring strips. Generally, strips should be placed 16 to 24 inches apart, depending on your project. Use a chalk line to mark vertical lines on the wall where the furring strips will go, ensuring that they are plumb (vertically straight).
Attaching Furring Strips
1. Position the First Strip Start at one end of your marked line. Align the furring strip with your chalk line and use a level to ensure it is straight.
2. Nailing Options You can use either concrete nails or masonry screws to secure the furring strips to the wall. If using concrete nails, use a hammer to drive the nails into the furring strip and into the concrete block. If opting for masonry screws, drill pilot holes through the furring strip and into the block, then secure the screws with a drill.
3. Securing Additional Strips Continue this process for the remaining furring strips, using your tape measure to maintain consistent spacing. Make sure each furring strip is level before securing it.
4. Final Check Once all the furring strips are in place, check to ensure they are secure and level. This will provide a solid framework for your next steps, whether you’re installing insulation, drywall, or other materials.
Conclusion
Nailing furring strips to concrete block walls is a straightforward process that enhances the functionality and aesthetics of your space. With the right tools and some careful measuring, you can create a sturdy base for your interior finishes. Whether you're a DIY enthusiast or a professional contractor, mastering the technique of attaching furring strips is a valuable skill that will serve you well in your building projects.
