The biggest change to modern paints is the development of water-based enamels.
Oil-based enamels are extremely high in VOC's - up to 350gms/L - which is why they are so smelly and are a major source of environmental air pollution. Using modern water-based enamels makes a huge difference to the health of the painter, the occupants of a house, and to our environment.
Painted Earth offers a water-based acrylic enamel MUROBOND Pure Aqua Satin. This contains 37.96g/L VOC which is a lot lower than any oil based enamel, and doesnt leave any lingering fumes.
