Green Scene Matte Medium--ballast adhesive?

[Crepello]

Having run out of PVA I resorted to neat matte medium for a ballast repair (Woodland Scenics fine); it seems to have the ideal properties and is presumably just diluted PVA anyway. I did forget to use a drop of detergent but seem to have got away with it. Could it be the answer for ready-mixed ballast glue?

I use that. I've never got dilute PVA to work.

I mist some alcohol over the work and then add the glue (Scenic Cement?) with an eyedropper at the side. The misting keeps the spray from moving the ballast around. (I scrounged a mister bottle from my wife's hairdresser.) I try not to spray glue over the rails.

When I do scenery (ground foam) I use the larger sprayer from WS and worry less about displacement.
