What to do? Who to call?
Hi, this is my first post and somehow it seems ironic that I can't even figure out which forum I should post this question into.
I live in Alberta Canada and have purchased a 1930 bungalow similar to one I owned for over a dozen years. I also live in a very hot market so there could be no conditions such as having the house inspected but having had one before I was not feeling too concerned as many things are similar. Have no fear, just for peace of mind I am going to call in an inspector but it may not be until fall. I'm also pretty experienced when it comes to fixing old house things now but this one has me wondering.
The issue is the basement walls are spalling. I truly believe it's decades old but it looks bad and I would like to fix it. There are some rather large areas (like 5 or 6' by 4 or 5' and maybe 1/2" deep). Someone painted over some areas, others are exposed but cleaned (no loose stuff) and still other places need some cleaning to get back to solid concrete. There are no signs of water damage or moisture. It does look like previous owner tried some sort of cement in a couple of spots, but didn't do it right or had the wrong cement and it's not adhering.
I know someone who said she got her basement (which was similar) skim coated 30 years ago and it's been fine. What she can't remember is who she called. I have no idea who does this type of work or who I should be consulting about it. So if I am looking in the yellow pages, where would I look?
Better yet, can I fix this myself? I have done a bit of reading but it usually applies to a horizontal surface so I am not sure if this is the same. It seems to indicate I need to clean all the loose stuff away, use some sort of adhesive or bonding agent and a product (one I have heard of when it comes to horizontal surfaces) like TopNBond. Meanwhile, I am not sure I am getting the right information and do not want to do this twice or worse, make it worse.
Please, any advice is appreciated.
