Ballast
Ballast
As SB said in another topic that he wanted to know what my technique for ballasting was, here it is. I use grano dust that has been sieved to get the small bits out. Then this is mixed in a 1:2 ratio with cement (one part cement to 2 parts grano dust). This is laid dry, using a old paintbrush to get the ballast into place. Then using a spray bottle, spray on water with a bit of outdoor PVA, making sure that all of the ballast is wet, you can tell from the cement. Then just wait for it to harden. I use normal cement but I've heard rapid setting is better for this job.

Ah, thats probely by my first effort didn't work, I used fishtank gravel that may have been too big. Probebly should of mentioned that my dad sieves the big bits out as well as the small bits, but I thought it didn't make that much difference. My dad does most of the ballasting on my line
