Linseed oil paint offers a healthy, durable alternative to acrylic products. Ottosson’s product is manufactured at their facility in Genarp, Sweden, which was established in the late 1980s. The technique used in making their paints, however, dates back to the 16th century. Cold-pressed raw linseed oil and natural pigments are ground in a triple-cylinder mixer, incorporating the pigments evenly into the linseed oil. The result is a linseed oil paint that creates a breathable, easy to maintain surface that doesn’t peel or bubble up.

*NOTE: Ottosson Linseed Oil Paints contain zinc oxide, a natural fungicide. It adds hardness to the paint finish and is a necessary additive in several North American climates. Zinc requires a warning label due to potential aquatic toxicity under Swedish law. When disposed of responsibly and used as directed, it poses no threat to the health of humans or the environment

Graphenstone has updated traditional lime paint formulas with their product by adding graphene, a material made from carbon. Graphene lends the paint extreme strength, durability, and washability. Additionally, the use of lime creates a paint that is not only free of harmful substances, but one that also actively improves indoor air quality by absorbing toxics and CO2. The white interior and exterior paint have a Cradle to Cradle Gold certification.

This product meets HML's criteria for low embodied carbon in part because of its use of renewable energy and CO₂ absorbing ingredients. As the product is produced in Spain, shipping can negate it's low emission score.

*NOTE: Recently, researchers have raised health concerns about graphene. According to the manufacturer, Graphenstone uses Nano Fibers of Graphene (NFG), which has a larger structure that is not harmful to human health.
