Using House Render to make Cliffs/Cutting Walls

 

To make simulated cliffs /cutting walls, I use Acrylic House Render coloured with an Oxide which is applied over fibre cement sheeting, preferably over the rough side for better adhesion.

Method;

• Make a dry mix of the render and some oxide (amount used can be varied to give the desired colour) 
• Add water to make a paste similar consistency to cement mortar used by bricklayers 
• Wet fibre cement to slow down water absorption from render to stop it from crumbling. 
• Trowel render onto the fibre cement while the backing was still damp. 

Optional; acrylic paint washes can be applied to dry render to give different shades and to break up the colour.

The render can also be applied over polystyrene.
