My new-to-me house has cinder block construction on the older portion of the house. There are some stair-stepped cracks in the block.
I can see where previous cracks have been caulked and it appears that there have been some more extensive repairs that required more than caulking. I cannot see any areas right now that need extensive repairs. All of the cracks are hair-line as shown in the photos.
1) Is caulking the best way to seal up these cracks? If not, what is?
2) If caulking is the best way, what kind of caulking should I use?
I've attempted to insert photos. Thank you!!!
