Use a wide paintbrush to paint the Besser blocks. Using your construction adhesive, secure three blocks on top of each other in a horizontal position. Expose only the holes in the top block. Repeat this to create four separate sets of three blocks. Use cement filler to fill the gap between blocks.
Sand the timber well for a smooth finish and apply varnish.
Move the blocks to their final position. Use your construction adhesive to glue two sets together for one side of the bench and repeat for the other side. Glue a single block in a vertical position on top of the back set on both sides for the backrest.
Insert the timber pieces into the slots of the Besser blocks. Add cushions to style your outdoor bench.
