I've been playing around with various options for yard ballast.
The "cinders" I've been using isn't quite doing it for me.
I did a little online searching and came across the use of "sanded grout" as a ground cover. I liked the visual results I saw in the photos. So I bought a box and started playing with it.
I found that just bonding it down with water and relying on the integral bonding agents to be inadequate. Thin Weldbond left a shiny surface which was not acceptable.
So I bought a jar of Acrylic Matt Medium. Thinned it about 3-1 and this is the result.
I'm not sure where to go next with this. Can I even cover this or do I have to rip this section of track up and start again?
I've never heard of this happening with Matt Medium. WTF?
