Not getting the results expected from a static grass applicator? The problem may be the glue being used.
Aside from a good applicator for static grass, an often overlooked aspect of getting the perfect finish is the adhesive used.
Picking the wrong glue can result in static grass lying dead and flat, looking more like wet dog hair than beautiful grass flowing in the wind. Or even having fibres that aren’t held in place and float off at the slightest breeze, typically on your rolling stock, track, models and figures.
There are lots of glues available so which is the best glue to use?
However, PVA by itself is too thick, the individual fibres will struggle to break its surface tension and instead fall flat. Worse, as they build up, they will end up being pushed into the glue and become matted.
Even when the fibres do break the tension and get into the glue, it’s too gloopy and the fibres can’t move and stand up as the charge pulls at them.
What’s needed is something to reduce the surface tension, diluting and improving its consistency.
And the secret sauce…
Over the years and layouts, I’ve found a 50/50 or 1 to 3 glue-to-water ratio to be a good mix for static grass. To this, I then add a few drops of Isopropyl and then stir it up before applying it to the baseboard or mini-figure base.
With that done it’s just a case of scattering the static grass using your preferred applicator. With this adhesive and the secondary wire placed touching the glue near where you want the grass, you should find it stands up much better and remains in place longer.
