Guys,
I'm looking to buy some PVA glue for Ballasting.
A lot of the stuff I see is described as washable.
Does that matter? A suggestion of what to get would be helpful.
Cheers 🍻
My favourite is Wickes' own brand. It works fine when diluted for ballasting, scenic scatters etc. and for actual woodworking I find it's slightly "stickier" than some other brands :) To be honest any of the stuff in a typical DIY store is probably going to do the job. I don't worry about whether it is "waterproof" or not, it still works.
if its waterproof, it will be difficult to lift track after its set.
You can always soak the non-waterproof with paper towels to soften it.

I've not had a problem, though I only ever lift track to totally replace a damaged point or something - not with any intent to try and re-use the track. I'll cut through the rail, soak the ballast and lever up the piece to be removed.
I prefer Woodland Scenics Scenic Cement. Pre-mixed, with a wetting agent built in, very easy to use, excellent application with a dropper. Thoroughly recommend it.
Thanks guys.
I have some Gorilla wood glue.
I don't have a massive amount of ballasting to do, so hope I could use this.
Thanks.
I can't say I've noticed any difference between the tackiness of PVA glues - at the moment I have UHU, but the Migros-branded and Ponal glues before were just as creamy.
Important is to dilute (between 1:3 and 1:4) and add a drop of washing-up liquid to reduce the surface tension. I also wet the ballast with a fine spray of water, also with a drop of washing up liquid, before starting. The PVA then soaks through the ballast without creating craters. I use a hypodermic needle rather than a dropper for finer control.

Thanks for the help.
I'll practice on a 6" offcut of track before I go all in. There's a short section into a tunnel I can do first, so I can put the hillside over it.
Cheers 🍺
