seams on pink board

I duct taped my seams and added scenery over that. That was seven years ago, and it still looks fine.

I used caulk on my seams, as long as the gap isn't too large this works well. Im not sure how detailed you are making your layout but secenry materials i.e. ground foam, grasses weeds etc make seams disaapear quickly. I actually painted the foam right before I would scenic an area that way the material could stick to the wet paint. The next day or so I would spray it with the white glue/water mixture to finish securing it.

I use spackling compound between the joints.  Then I paint the base coat with latex paint.  Then spray diluted colors to "stain" the rocks and finish with a dry brush of white.  Makes great looking rocks.  Or just cover the area with dirt or ground foam. Check out a guy on you tube by typing in "thebige61"  he does an entire clinic on foam.

I use 3" wide masking tape. Then I paint everthing with brown latex paint. My scenery goes on top of this. It's quick and easy and doesn't show.

I used duct tape and applied scenery right over it, sand and fine ground foam then coated it with 50/50 water and elmers glue with no problems.

I use plaster cloth.  Some people here like to paint the foam.  I like to cover everything in plaster and use washes to get my color.  Duct/masking tape will not work for a rock face.

Use adhesive drywall tape.

 

 

 

Thanks all. Big help, will try to plan ahead as the railroad marches on! Seams there are many many details to consider. ( pun intended)

I am with wsdimenna. I used the adhesive drywall tape (looks like a net) and then put joint compound over it and smoothed it out. I even used it to even out a small change in elevation between one portion of our layout and another. Then painting it the same color as the rest of the foam is easy breezy.

Wsdimenna, what did you use for ground cover for the path in your pic?

the adhesive drywall tape is covered with fusionfiber tinted brown. This was followed by stones and deadfall pressed into fiber. Earth blend and  pasture blend from scenic express was used for green areas. The gravel road is scenic express ballast on fiber tinted brown.

 

Sometimes I leave a space between the foam bases. The combination of adhesive drywall tape and dry fiber with ground covers can be flexed without cracking. Makes it easy to install.
