Excited, have benchwork up for my first layout other than Christmas. The top is half inch plywood covered with one inch insulation board. Is there a way to cover the seams in the board or do I just not worry about it? No gaps, just seams. Thought I would ask before I paint it flat medium brown! Thanks for any responses!

If you like to scenic, the seams will stand out unless you put on several layers of ground foam, preprinted roadway or some structures.  Although I use all three on my layouts, not everything gets covered.  I prefer the exposed areas to be smooth, so I fill and sand smooth with joint compound (spackle).  To fill larger gaps I start with painters caulk then smooth with joint compound. 

What do you mean by insulation board ?  I used Celotex also called soundboard.   The paper fiber board, not foam.   This is how I covered the seams.   I had some old white cotton bed sheets,  cut into 3 inch wide strips.   Mixed white glue and water, brushed glue mix over the seam,  soak the cotton strips in the glue mix.  Then carefully spread the strips over the seam, careful not to get wrinkles or bubbles,  brush on some more glue mix, let dry.  Then paint with earth color brown.  The seams are hard to see.  After adding ground cover they are totally gone.

Thanks for the reply Steve! I used the green insulation board from Lowe's, same as the pink and blue stuff. Thinking I will paint as is, start landscaping etc and then hide with tape anywhere not covered by something then paint over it and sprinkle ground cover! The only trouble with a first layout is you know you're going to make rookie mistakes and you drive yourself crazy trying to think of everything! I am sure this isn't the last question I ask here as things progress! LOL

Thanks for the replies! This forum is truly a blessing for neophytes like myself! Richie I have never seen brown duct tape, where do you get it?

WalMart has cheap stuff in the Office supply section in colors. 

Tape just makes two more smaller lines. Fill it with a narrow bead of caulk and finger it flat.
