Sorry to hear about your ballasting woes Nick. I've always used a 50:50ish mix of water to bog standard PVA, with a touch of washing up liquid. Adjust the thickness of the mix until it flows and soaks nicely. I place and shape the ballast, mist with water and then drop on the PVA mix. Takes a day to dry solid.
Never had a problem with it being conductive (almost sounds like the glue you have used was formulated for static grass use). I use Woodlands Scenics ballast which is ground up from nuts (or something) but means the result adds very little weight to the board compared to stone. An advantage of the PVA is that applying drops of water afterwards will soften the glue and enable the ballast to be easily removed.
