We were approached by Chatsworth Estate 2 summers ago to see if we could colour-match their eponymous blue. They had previously had problems with the quality of the paint supplied by their existing supplier, as well as incorrect information on the addition of zinc white.
The blue paint they were supplied always lost its blue and turned grey over time. The great team at Ottosson Färgmakeri easily changed this to make sure that paint was made using the highest possible earth pigments and making sure cobalt blue was used instead of ultramarine (which bleaches by exposure to UV light).
Ottosson also make sure that zinc white is always added to the paint in the factory, to get the best anti mould-growth properties. Order the paint here.
"Oricalcum linseed paint is tremendously easy to use and very cost effective; it reduces our maintenance cycle, application time in labour and cost in joinery repairs."
