Introducing eco-friendly paint

New to us is Graphenstone – a range of paints composed of natural elements. For those who are concerned of the health implications of ordinary paint, Graphenstone is the solution. Among preventing mould growth, these products will also aid in purifying the air of indoor environments.

They have a beautiful variety of colours available to view in store – and better yet, we can mix the paint for you on site.
