We live in a old cinder/concrete block home that we rent. I have had to change the curtain rod over a large window and I used masonry nails. Well, I want to change the rod and the curtains. My question is should I use masonry nails or is there a better option. This house has many nail scars and I don't want to cause more.
Also, is there an advantage to putting up drywall over concrete walls?
Again, we have a mold problem on the inside of the house around the outside walls. Does seem mean we have foundation problems? There is a crawl space underneath.
I second the Tapcon recommendation. Especially with concrete block, rather than pounding in a big fat nail you drill the correct size hole and then thread in your Tapcon screw. They will have a whole section of them at HD including the drill bits.
