Conclusion

There are a few different ways to finish off the concrete block walls for your shed. One way is to simply caulk the joints between the blocks and paint the entire surface. This will give you a nice, clean look that is easy to maintain.

Another option is to use a concrete sealer on the blocks. This will provide a more durable finish and will help to protect the blocks from weathering.
