hi gang.
living in a condominium from the early 50s and have replaced the floor in one room and now need to install new moldings. the tricky part is that the walls are made of quite porous concrete so nailing or screwing is not an option, but then I thought I would use adhesive. I was thinking of buying pl600 but I'm not quite sure if that's the right choice.
another tricky thing is that the exterior wall is basically like an S, it feels like. It was probably perfectly straight by 1940s standards, but now there's a centimeter difference in depth at both edges and in the middle of the wall, so it needs to be a super fast-drying adhesive.
grateful for help!

List nails work in lättbetong, if that's what you have? Flat, blunt, wedge-shaped nails that come in white lacquer or brass-colored. If nailed in at an angle in opposite directions, they also lock each other. Complement with PL400 if it doesn't adhere well.
I think it's some form of concrete plaster on the outermost layer. It seems to be very porous anyway...
I installed moldings in a 1940s house with a similar construction and it worked quite well with nail plugs. This assumes that you have painted moldings so that you can fill over them. Because the nail plugs are quite large.
Those who installed the original moldings in the 1940s nailed them with hand-forged nails. It apparently works because they are conical.

Yes, when I pulled out the old strip, they were held with nails that were completely square. That's what I call a nail! 
I'll try with nail plugs. I'll get back to you if it doesn't go well.
Thanks for the help, gang!
