Margaret glue will be your best friend (liquid nails) but you can rent a nail gun made to shoot nails into concrete. Depending on the weight of the ship lap you're planning on using will determine whether or not you'll need to rent a concrete nailer.
I have a nail gun that is supposed to work on concrete but still find it difficult for it to hold a nail. Unfortunately, the condo is all concrete and so hard to hang things on walls, I'm afraid glue wouldnt hold, but thanks for your reply
Hello Margaret! Here's one person who put up furring strips and then a plywood wall over their concrete wall. You could use water proofing on your concrete wall first and then insulate as well if you did it this way.
Thank you so much, not sure I am that handy but it looks like a great solution
here is another idea for you
How To Install Shiplap Over A Concrete Wall
You would need to fir the wall out with 1X2 firing strips. Add foamboard insulation if you want. Then nail the ship lap to the firing strips.
Here's some tips
Hi Margaret: You could use Liquid Nails or QUIKRETE® Polyurethane Construction Adhesive if you don't want to nail the furring strips to the walls, then proceed with the foam board and nail the ship lap to the furring strips. Before attaching the foam board, make a mark where the centre of the furring strip is, above each furring strip on the ceiling, or on the floor, so you will know where to nail the ship lap. Good luck
