Controlling Moisture in my Shop

One of the big draw backs of the space I am using for a shop is the total lack of climate control. I have said in one of my last post that it is like an above ground basement, let me explain that statement, what I have is a block building with a brick face and a concrete floor with no windows or doors except the main entry door. There is no heating or air conditioning and it seems to sweat moisture around the wall and floor joint. With no windows I also have no air circulation except the fans I have placed to keep it moving in a around the shop.

Now I know I am going to have to address the heat, but I still have six months to work that out, and with the wall being 12" of cement and brick it stays fairly cool although damp and with two fan constantly moving air ti has been comfortable, but a dehumidifier would help to at lease keep moisture levels to a decent place to store wood and build furniture and on my list of must haves, I am just trying to find a used one before buying new.

I am also considering painting the walls with a moisture blocking paint made for block walls like Dryloc, and cleaning and caulking the seam between the floor and wall with a hydraulic blocking caulk made for wet basements to try to stop any water that may be getting in that way.  This would help stop the walls from sweating and collecting on the floor around the shop where I have been seeing most of the moisture. The I would like to seal the floor with a good cement floor sealer.

 I could go all out and fur out the walls with some 2x3 and put up some 1 1/2" solid foam board and cover it with plywood or OSB, but since I rent this space I really think my money right now is better spent else where, like on wood for projects. I really don't want to turn this into a project where I build a great shop, but a shop where I build great projects.
