So I continue to slowly move along with the groundcover. I made some more progress last night, and it appears that the sections I did (including fixing the areas that had turned white) are working OK. For this section it would appear that moving slowly is the best approach, and using as little glue as possible (in this case Pledge Floor Care Finish, formerly known as Future). In the past I've done the usual 'flood the ballast' approach without any issues except on my layout.
The AC is keeping the humidity down at home, so I don't think that's the issue. As I glue down the foam in other areas of the layout I'll use wood glue instead of a water soluble glue and maybe that will help.
The basic process is relatively simple. The track was spray painted with Rustoleum camouflage in place. I don't bother protecting the railheads or turnouts. I just use a brightboy to clean it once the paint has dried. I haven't had any issues with the turnouts that a little cleaning with a scalpel, dental pick, or file doesn't fix.
The ballast is a mix of Scenic Express light limestone mixed with a little charcoal grout to make it a little darker. I sprinkle that and some real dirt using my fingers for placement. I follow John Nehrich's recommendation for a well defined ballast line, although instead of masking with tape (which I think leaves a bit too much of a recognizable edge), I just use a piece of cardboard as a mask, held just a little bit off of the layout to give a defined, but slightly 'fuzzy' edge. I also sprinkle on a little Woodland Scenics fine ground foam for a little variation.
I'm really happy with the results so far, so I'll keep working through the occasional white glue incidents. It's annoying, but hopefully I'll only have to deal with it once.
Well, twice since I've already taken everything out once!
Glad I found this! Excellent! Can't wait to put this to good use!
