The canal or wharf retaining wall has now been painted. I used low-tac masking tape to mask off the painted groundwork before painting the stone wall in various greys then drybrushed and washed the stones prior to painting the wooden strakes or rubbing strips. I had seen in some reference photos that the stones were both highly worn and colourful and I have tried to copy these features. Finally the green algae was added with washes of dilute acrylic paint.
The cast iron metal waste outlet (copied from one I had seen in the Droitwich Canal) was painted in various rust effects. At the same time the iron mooring rings were painted in the same mix and rust staining was added along the wooden strips with both paint and powders.
