Fixing ballast around card buildings
« on: September 11, 2017, 09:48:06 pm »
I'm putting down ballast (actually ash) around the track and general ground area next to a card engine shed I've already glued in place. My query is how best to fix it in place in a way that doesn't cause water to soak into the building and distort it (I had this issue before with my station platforms when I used the PVA/water from an eye dropper method).

Does anyone have any suggestions on how to fix the ash ballast?

I don't fix my buildings down but once in place, I use a small flat paint brush to bring neat PVA up to the edge of the structure. Being undiluted I find the glue wont run.

If a second coat of whatever material is needed and once the first coat is dry, I simply repeat the process.

I saw this earlier today Oz time, and refrained from replying because I didn't really know! I've fixed ash and scatter materials right up to heaps of glued down buildings, but when I thought about it, they were all plastic!

The only card one I did was a scratchbuilt affair painted with Humbrol enamels, so it was immune to the pva/water mix.

Your idea of the neat pva is a good one, Dave!  :thumbsup:

Thanks Dave. I think I'll try to make a "paste" from neat PVA and ash and work it in around the building and surrounding area.

If you hadn't fixed them down yet, I've seen a suggestion to cover the bottoms in cling film and put them temporarily in place while you ballast.
Since they are fixed down, can you put a small 'shim' of plastic against the edge of the building to protect it? Thin plasticard, or a lemonade bottle?
Try on something scrap first.

So, I made a paste of PVA and ash and spread it around the building, then using the dropper method to fix the rest in place. Came out OK I guess but it was a bit messy working that stuff.

Looks pretty convincing. Are you a heavy smoker?😆
I'm not sure if life is passing me by, or trying to run me over.

I think you've done a very good job. Captures the filthy character that those places used to have very well indeed.  :thumbsup:
