The basement is being cleaned up–but it is still a basement. It has tools, workbench, etc. The outside was recently water “proofed” and additional drainage added along the foundation.
The block is messy on the inside. There was some spalling, and there has been other damage that has occurred in the past 80 years.
I have some thinset left over from my bathroom project. After getting rid of the loose stuff on the surface, is there any reason why I could not use the thinset to get a smoother surface?
I was then going to paint it with some leftover waterbased paint, just to brighten the place up.
