I have a frame house that sits on about 4' of split-face block. The house is 30 years old, and I was pressure washing the block to re-seal it. Noticed a number of gnarly cracks like this one:
- I'm hoping this isn't caused by the pressure washer (going at about 1600psi, moving quickly enough to get the grime off)
- Is this something I can just seal with an epoxy or caulk (material-appropriate), or do I need to tuckpoint / replace the mortar?
