I needed to make a relatively large expanse of station yard and road on my new layout Valdieu-Lutran. I decided that chinchilla dust, a form of powdered sepiolite clay, would be a good base. I initially tried to stick the dust to the baseboard using diluted PVA but this was unsuccessful because the clay did not stick well. After the glue had dried the dust easily rubbed off.

I therefore undertook some experiments to find the most effective method of sticking the chinchilla dust.
I tried wallpaper paste, Aleene
I have used Chinchilla dust quite a bit for texture. It stuck ok for me with PVA but then I put other things over it such as a mixture of paint, PVA and wood filler (I am modelling WWI mud). I used it in brick dust too. I use my trusty tea strainer for scattering and then my USB vacuum to take up the excess once it is dry.
PS Good job!
