Sealing the Block Walls

6 photos · basement

The other half of the basement is original cinder block — egress window, slab floor, and a corner that was actively wicking moisture. Rather than fight it with framing and drywall that'd just rot again, I cleaned it, sealed the block, painted everything white, and put a gray sealer on the slab. Honest storage and laundry space. Lets the block breathe.

  5. Under-stairs got the same paint-and-seal treatment. Now it's actual usable storage instead of a damp triangle. After

  6. Other side of the block room, same finish. Not fancy — but dry, clean, and easy to keep that way. After
