When I make a pond for a model railway layout I prefer to use a piece of glass to represent the water as the material has a highly reflective surface which can easily be cleaned to restore its lustre. I apply very light pressure when cleaning the glass to minimise the risk of breaking it.
In my experience a model pond constructed using resin can go dull after a while as micro scratches build up on the surface when it is cleaned. I find that this is also the case when transparent plastic is used to make a miniature water feature.
Water features such as ponds and lakes tend to sit at the lowest level within the landscape which is why I wanted to enable the piece of glass to sit slightly below the rest of the railway layout scenery.
Filler was used to bed the glass into the surrounding landscape and allowed to dry.
I painted the filler with green emulsion paint. When the paint had dried I applied green scenic scatter to match the surrounding model scenery.
Rounford Halt is one of my N gauge scenic model railway layouts. To see more model railway layout baseboards I have designed and built visit my website www.brianford.co.uk.
