New developments with Graphenstone Four2Four Primer

And why you should consider using a tinted primer when redecorating...

Graphenstone  mineral paints

Graphenstone has launched three coloured primers.

What colour primer should I use?

Undercoat and primer paint is necessary to achieve a full depth of colour. Coloured primers play a significant role in the overall finish of your surfaces; in general, your primer choice will help you get from your current surface colour to your chosen colour with a lot more ease. Darker primers yield deeper, darker colours, and white primers will give you brighter hues. Now that you know how primers affect your final paint shade, it's time to pick a primer and get to work!. 

Graphenstone primers are designed to help even out the surface of walls and timber before overpainting with eggshell paint. Four2Four premium primer is a bonding agent suitable for any common surface, ideal for indoor and outdoor use.

Four2Four Primer is available in White, Light Grey and Dark Gray - 1 litre and 4 litres.
