Storm The Castle Diorama Part 7 : The Moat, Water Effects!

In this part of the tutorial we do water effects! We make the moat around the castle. And we use Lexan and Medium Gloss Gel. It is an easy process and you just need a few basic supplies.

I also have a video tutorial you can watch. It is at the bottom of this page.

Back to the this diorama home page


Here is a look at the completed Moat.

The Castle and the Moat


The Moat


Materials and Tools Needed for this Project:

  • Polycarbonate sheet - How big and how thick depends on the size of the water you are doing. 1/8 inch thick is usually adequate. I used a 48x36 inch sheet because this moat is so large.
  • Blue, Black and White Paint
  • Medium Gloss Gel
  • Various cutting tools for cutting the polycarbonate and the foam terrain


Sheets of polycarbonate


You can get polycarbonate sheet (clear plastic sometimes called Lexan) just about anywhere including the Home depot. It comes in different sizes and thicknesses.


Overview of what we are going to do:

We will measure the lexan sheet and cut it to size, oversized for the moat. Then we wil cut it. And then cut away the foam so we can lay the lexan moat right into the foam. This gives us a nice water level. Before placing the lexan sheet into place we will paint it.

This picture gives you a really good look at what we do in this tutorial. See how the pink foam has been cut in half? And see how the sheet of painted blue lexan has been placed. That is the water level.


Ok, the first thing we need to do is measure and cut the lexan to the desired shape. I laid the full sheet of lexan right over the moat, covering it all.

Placing and measuring the lexan


Then I marked the lexan with a marker. Going around the water way with about an extra two inches all the way around it.


Cutting the lexan

Then I cut the shape right out with a lexan cutting tool. You can also do this with a jigsaw or hacksaw. But take your time and be careful, it is easy to split and crack the lexan.

There you go! The Moat is cut.
