At MGN Builders Merchants, the Colour Mixing Lab gives you precision colour on demand. Using certified Dulux Trade and K Rend systems, we mix exact shades with batch consistency for interiors, exteriors, and rendered façades.

We can also mix any BS, RAL, or standard colour to order — with no minimum order quantity. Many mixes can be prepared and collected the same day, ensuring you get the paint you need without delays.

Available in-store at our Orpington, Woodford, and Romford branches, serving London, Essex, Kent, the South East, and beyond the M25.

How It Works

1. Bring your reference – arrive with a picture of a house, a BS or RAL colour code, or any standard brand colour code. Our machines will scan or match it with precision.
2. Choose your system – Dulux Trade for interiors/exteriors, BS/RAL for custom colours, or K Rend for silicone render topcoats and masonry.
3. Pick a shade & finish – bring a colour code, sample, or select in-branch from our extensive colour libraries.
4. We mix & label – certified machines ensure colour precision is guaranteed; each batch is barcode-labelled for easy re-ordering.
5. Collect in-store – many bases and BS/RAL mixes are available within minutes, ready the same day.
6. Need it delivered? – we can also arrange fast delivery direct to site or home, ensuring your project keeps moving.
