Still ... I once did a pour of realistic water (the other product) and it literally took over three weeks to become clear. I have used water effects in several places and it always goes on white and eventually dries transparent to translucent.

Of course, there is always the drastic measure of scraping it off, Personally I would wait a while first.

I think that your gloss medium trick would work. You might want to use more than one layer, tinting only the bottom ones. Our local small river (about 200 feet wide) often runs brown during spring runoff. One can see a short way below the surface. Our large river (the Hudson) is more transluscent but still brown.

11. CREATING WATERFALLS

Modelling waterfalls can be a task fraught with frustration and heartbreak. Because of the nature of the feature it is difficult to model, but it can be done, well almost any way!

Here are three methods I have used to produce a reasonably realistic model of a waterfall.

Clear silicone sealer is spread onto a sheet of glass to form a long thin strip, the width of the required waterfall. If the glass is smeared with Vaseline or petroleum jelly before the silicone is added it will be easier to remove. Once the silicone has dried, peal it from the glass and you now have a waterfall. The silicone strip can be glued in place with a blob of silicone in the prepared area with the smooth face inwards. Adding a touch of full gloss varnish to the waterfall and adding some off-white foam at the base of the drop will give your waterfall a better appearance.

Another method, which also uses silicone sealer, is to reinforce the strip longitudinally with thin clear plastic filaments. When I used this method to produce a waterfall, I obtained the filaments from an old T.V. light that consisted of a spray of thin clear plastic fibres illuminated by a coloured light. The reinforcing produces a hint of vertical fall in the waterfall and also gives the silicone some body so that it is easier to handle.

A simpler method is to glue clear plastic strips into position and to coat them with full gloss varnish. If the varnish can be poured into the river above the falls and let run down and over the falls it does produce a good representation of a waterfall. Again add white water and ripples below the falls to give the correct effect.



Good luck with modelling your water.
