Remodelling a room like a basement may include dealing with a breeze block wall that needs sprucing up to make it look less like breeze block and more like an interior wall. Breeze block can often be found in basements and create an aesthetic problem when trying to make them a warm and liveable space. For an easy and inexpensive solution, you can install drywall or panelling on top of interior breeze block walls by attaching furring strips onto which you lay the new wall material.
Clean the wall to remove all dirt, grease and loose concrete material. Allow the wall to dry thoroughly.
Caulk any cracks in the breeze block surface to provide a smooth, even surface.
Measure the length of the furring strips you will need to fit horizontally along the floor and ceiling, and the height of furring strips you will need to fit vertically along the wall.
Cut furring strips to the right length to fit along the top of the wall and the bottom of the wall.
Cut enough furring strips to fit vertically 16 inches apart, centre to centre.
Mark the wall to guide positioning of the vertical strips.
Pre-drill pilot holes in the furring strips as recommended by the manufacturer with a wood bit to accept the screws. Set holes about 24 inches apart.
Position the furring strip along the ceiling horizontally and drill through the strip and the breeze block with the masonry bit to a depth of 1 1/2 inches. Vacuum out the hole to remove all loose debris to allow the fastener to hold to solid material.
Insert the tapcon screw and secure into the breeze block with the power screwdriver to hold tightly. Continue to the end of the wall. Repeat to attach the bottom furring strip at the floor.
Position vertical furring strips on the wall following the marks you made. Drill to a depth of 1 1/2 inches and vacuum out.
Insert screws into the holes and tighten with the screwdriver. Continue to the end of the wall.
Align panelling or drywall along furring strips and secure with nails.
According to HomeAdditionPlus, you can add rigid foam insulation panels between the furring strips to give additional insulation to the wall. (see reference 1) According to FamilyHandyman, you should keep additional drill bits on hand in case of breakage. (see reference 2) Breeze block is a very hard surface that can cause bits to break easily.
You should deal with moisture problems before installing new drywall or panelling over breeze block. Seal cracks with water-sealing concrete patch material and put up a moisture barrier to keep the moisture from ruining your new wall. Wear goggles when drilling concrete and sawing wood to protect your eyes.
