This afternoon, the bottle of gloss medium arrived, so I poured it over the creek bed, thickness somewhere between 1/16" and 1/8". This stuff ("pourable gloss medium") is a bit thinner than the stuff I used previously, but it was still pretty thick and I had to work it along the edges to get it to level out. We'll see how it looks when it's dry!!

Before the pour, looking back towards the temporary dam at the edge of the layout:


And the pour:

Well if that's any indication on how the flow looks and dries like that. It could be a home run Dave!!!

I agree, as long as the "run" isn't to the "home" through some invisible pinhole and thence down, down, down....

This should create a very nice base for whatever wave action you decide to add later on.

Best wishes for a great cure!

Well, there are some cracks in the pour, and it didn't self-level very well. It's A Good Thing this is not the final coat.

I once used a thick pour of gloss medium to make a pond and it too cracked in the process of drying. I was hoping you would have better luck. Still, it sounds like you have a plan. It will be a very dramatic scene in the end.

You can see some of the extensive cracking and shrinkage here.


My plan is to do another pour of the gloss medium, just to fill in the cracks. (Another bottle arrives tomorrow.) Then I'll do translucent paint on top of that, and let things dry thoroughly before doing a Magic Water pour for the main coat. A little unevenness in this layer won't be a problem, it'll just look like "water turbulence effects" underneath the clear Magic Water (I hope!)

I'd consider waiting a week or so for the white bits to cure out, and then reevaluating. Your overall Plan sounds good to me, but keep the coats thin!

Best wishes!

As Pete said keep the coats thin. The cracks occur because the drying from top to bottom is different. Thinner coats dry more evenly and shouldn't crack.

The white parts are still moist and probably somewhat soft. Cleaning a Gloss Medium surface with water can re-moisten it enough to get cloudy, but not outright white. Filling in cracks is going to produce more thick/thin sections. I hope it works, but I'm a little afraid that your cracks may be filled with more cracks.

Dave,

That looks like what happened to my pond. Id give it lots of time to completely cure.

Dave,
Hm... two part mix for the gloss medium?
Anyway let everything cure until the cloudiness goes away. You have a lot of bubbles in there also. Try exhaling across the pour to pop the bubbles next time. Pour a very thin layer to fill the cracks. Let cure and go from there.

Worst case scenario... tear the river bed out and start over... Yep... done it... and it hurts... or... very turbulent water flow if you can live with it.

AFAIK the carbon dioxide (exhaling or from a flame) is specific to epoxies like Enviro-Tex.
