Not just natural, but effective too. There are lots of eco paints on the market but very few with really good technical products to back them up. Auro primers are an important first step in an effective natural paint system. The emulsion smells lovely, the wood finishes are all water-mixed and all the ingredients are from renewable sources. Great stuff. Please remember that the colour chart below is just a rough guide. Just click on any colour to take you to an Auro sample in that colour.
