In this video, modeler Martin Tärnrot discusses the creation of grass-covered ground surfaces on model railroad layouts. This will include a look back at techniques of the past and what is done currently. Before the static grass that modelers commonly use today, grass was made from fake fur. To color this fake fur, Martin uses a toothbrush with an artist acrylic or oil paint in green. To apply it to the layout, he cuts out the piece he needs and glues it down onto the layout with a wood glue. He hides the cloth the fur is connected to by tucking it under another element of the layout. For a more realistic result, he varies the color and size of the pieces.
For the static grass method, it is helpful to have a static grass applicator that transfers electrostatic voltage to the grass. Martin’s trick is to not fill the applicator all the way full. Vacuuming after application with the static grass applicator will tidy up the site where the static grass is laid, since the application is not very accurate. Before vacuuming, Martin puts a sock over the nozzle to collect the vacuumed grass to reuse later. About 20% of the grass truly gets stuck on the glue, so vacuuming the excess will greatly reduce waste. Static grass is available in a range of colors, thicknesses, lengths, and finishes. Martin reminds modelers that bent grass is poor quality and should be returned. He goes on to demonstrate high-density application of grass.
