When you say wooden slat wall "get up", do you mean something that a person could wear, or otherwise move around in, or an actual stationary wall? For plain old walls and such, I actually have access to some really decrepit looking old fence pickets, but I've seen artistic haunters make good facsimiles out of cardboard strips. Cardboard would, of course, be much lighter to set up and move, and if your haunt is entirely inside, you won't need to worry about the elements(I produce a hayride, so I think about wind and rain a lot).
If you're looking for something that can be worn and will flex with an actor's movements, you'll probably want to find some foam rubber, probably 1/2 inch thick or so, and paints that will:
a.) Stay on,
b.) Flex with the foam and
c.) Not destroy the foam.
That probably means latex, which fortunately is easy to come by. You can even get mismatched buckets on the cheap(relatively) and have them tinted to the colors you like.
I hope some of this helped. Once I know more about exactly what you're looking for, I'll be happy to help you get the look you're going for.
Howdy to all on the boards, by the way! I have a mild parenthesis addiction, so I hope my writing style isn't too distracting.
