Any suggestions for attaching wooden baseboard to Gysum wallboard where the wallboard is attached directly to a cement block fire wall.(no studs) I suppose I’ll have to use a construction adhesive. What’ll work best?

DC,
Any general purpose adhesive should work, even white glue. The trick is to keep the trim in place while it sets up. For that I use dab's of hot glue between breaks in the adhesive. Doesn't take much, but you do have to work fast with the glue gun.

I had that situation once where someone had drywalled over ceramic tile in a bathroom. HO asked me to fix the baseboard that was coming off the wall. I used liquid nails and pressed it to the wall with 2x4's and jacks pushing against the opposite wall.
Had to do this recently. I have a large collection of 1x1 and 1x2 of various sizes, and I just cut a bunch of it to the appropriate lengths, i.e. room dimension plus an inch or so. Use short chunks of scrap wood against the opposite wall and against the face of the trim to avoid denting it, and then spring the sticks into place. Pay attention as you go and put the sticks where the trim seems to ride away from the wall.
There are some very fast setting adhesives out now that will allow you to place the board and it will stick right away - remember the hammer getting glued to the ceiling comercial?

This may be a good use for Loctite's Powergrab. Assuming the wall is free of bows and dips, no bracing should be needed. Panel adhesive would also work, but the advantage to the Powergrab is that it cleans up with water.

Carpenters glue will work. Any overspill will wipe off with water. Shoot some 18ga 1¼" pins on an angle to keep the base in place till the glue sets up.
If you are hand nailing, use a construction adhesive like PL-200. If you press the glued base to the wall and then pull it off for about 15 minutes, the surface will become tacky and act somewhat like contact cement when you stick it back on the wall. A small nail here and there on an angle should keep the base tight till the glue sets.
Another option:
PL-Premium is a polyurethane based glue, polyurethanes need water to set-up. If you wipe the back of the baseboard with a damp sponge and put the glue on the wall the set time will be reduced significantly. Polyurethanes are waterproof and ideal for damp locations.

I'm with Gord. Use pins at an angle.

Another vote for angled pins to hold the base while the glue dries. I call it the "dovetail nail technique." It gets a laugh, but it works!Bill
