While the brick paper was drying I used 3M Super 77 Contact Cement to glue a 3′ scale strip of the foundation paper to each wall panel.  After this had dried I first painted the brick a brown color, using a PolyScale paint.

This became a problem later when I attempted to wash the brick with the white paint for the mortar.  Wiping this off ended up taking most of the brown paint with it.

I ended up moving on to installing the rest of the brick paper, but later painted the foundation a gray color later as the brown did not look good with the color of the brick.

I cut the brick paper to the correct height and length.  By carefully measuring I was able to score the back of each angle so that it would lay correctly.  The time spent doing this was well worth the effort as it took form made with cardboard walls and made it impossible to tell once the paper was in place.  I used the 3m contact cement to stick it in place, after I had masked the foundation and insides.
