I also used it to make water in my rivers. Once ground cover is applied, it looks fine - the little bit at the left, both between the tracks and below the bridge, was added to take advantage of glue run-off from ballasting and adding the rip-rap to the bridge approach tracks. It can be painted or stained: I started to paint it using full-strength interior latex paint, but found that thinning the paint with an equal amount of water made it much easier to apply while still giving decent coverage, and the paint will, of course, go a lot further. I apply it to the screen with a drywall knife, then use a cheap 2" brush to smooth out the knife marks before it sets, dipping the brush often and liberally in water. Once cured, and with the risers removed, I can lean on it without worry, a good thing, as this scene is fairly deep. Here's a semi-finished area, with Durabond 90 (90 minute setting time) applied over aluminum window screen, supported by temporary wood risers. There's a little more info on it here: HERE It can be sanded somewhat before fully cured, but it's very hard and durable (non-sandable) once cured. Other advantages are that it can be mixed to various consistencies without affecting the setting time or strength, and can be applied in as thick or thin an application as is required, without noticeable shrinkage or cracking. It has a catalyst which causes it to set in a predetermined time, and there are several setting times available. I use Durabond patching plaster, from Canada Gypsum (also available from U.S.
