The Knowledge of Cover Exterior Cinder Block Walls

Place vertical boards along the wall to connect the strips. Cut more furring strips to the size you used previously. Line these boards up with the edges of the wall, chalking straight guidelines as needed for the installation. Drill and screw these boards to the cinder blocks. Apply more vertical strips about every 16 in (41 cm) to create a framework for the vinyl siding.

Remember to install vertical boards around each door and window to complete the furring “frame.” These components need to be framed in order to waterproof them properly. Measure and cut the vinyl to fit evenly over the wall. Run a tape measure from the top edge of the upper furring strip to the bottom of the lower one. Add an extra 1⁄2 in (1.3 cm) to your measurement to account for overlap.

Then, cut the vinyl panels evenly to fit over the height of the wall. Use a circular saw with a plywood-cutting blade to trim the panels. Remember to wear goggles, earmuffs, and a dust mask to keep yourself safe while operating a saw. Attach a vinyl starter strip below the bottom furring. The starter strip is a slotted piece of trim used to hold the vinyl to the furring board.

Position it so it extends about 1⁄4 in (0.64 cm) below the lower furring. Place 1⁄4 in (0.64 cm) galvanized siding nails in the slots pre-cut in the starter to pin it in place. Look for vinyl siding kits online or at your local home improvement store to get all the components you need. Alternatively, buy the parts separately to suit your wall.

If you’re working around doors and windows, get more vinyl starters. You need corner pieces and J-channel pieces to connect them together. They attach to the furring boards the same way the starter does. Lay vinyl panels from the bottom of the wall to the top. Position the first row of vinyl panels over the starter strip on the bottom of the wall.
