Before applying the furring strips to the MDF board, we waxed the wood to create that vintage and aged look.
To attach the furring strips you’ll need some wood glue, pneumatic nail gun and an air compressor.
If you don’t have access to these tools you can use a good old hammer and nails.
(You can skip using any tools altogether if you want. Add a fair amount of wood glue to each furring strip and secure each board into place using large clamps. Allow the wood glue to fully cure before removing the clamps.)
Begin with the horizontal pieces. Apply a strip of wood glue along the edge of the MDF, line up the furring strip, keeping it flush with the vertical edges of the MDF and secure into place with the pneumatic nailer.
Repeat this for both the top and bottom horizontal pieces.
Then line up the vertical side pieces, apply wood glue and secure into place.
