After staining, allow around 15 minutes for the wood to soak everything in.
After this, wipe off all the excess stain using a rag.
Seal it using a polyurethane coating.

Next, moving on with the cinder blocks, arrange them appropriately where they will fit together.
Let it dry overnight.
After drying overnight, paint the cinder blocks using exterior paint (Valspar storm coat exterior).

Moving on with the upholstery.
Cut a 1/8 x 4x8 sheet of fiberboard using a handsaw.
Clean up all the sharp edges using the sandpaper sponge.
Lay down the fabric with the foam cushioning and fiberboard on top.
Wrap the fabric around, then secure it to the fiberboard using a staple gun.
Finish stapling both sides and ends before moving on to the corners.
Hammer the staples to extra secure it.
Place the foam cushions on both cinder block benches to finish.
