Graphenstone’s lime-based paints represent a breakthrough in sustainable building materials. Made with artisanal lime and infused with graphene, these eco-friendly paints not only provide a durable and attractive finish but also improve air quality by absorbing CO2 as they cure. The alkalinity of the paints naturally inhibits pathogens while resisting mould, mildew and bacteria. Whether you’re working on an entire building or a small in-home painting project, Graphenstone’s natural lime-based paints actively purify the surrounding air as they cure, with significant CO2 absorption occurring within the first 30 days of application.
Lime plays a crucial role in CO2 absorption due to the lime cycle, one of nature’s best-known examples of chemistry. The term “lime” refers to products derived from burnt (calcined) limestone, such as quicklime (calcium oxide) and hydrated lime (calcium hydroxide). Limestone, a naturally occurring sedimentary rock, consists of high levels of calcium and/or magnesium carbonate. When limestone or chalk (calcium carbonate) is burnt in a kiln, it turns into quicklime and releases carbon dioxide.
Adding water to quicklime produces hydrated lime. This unique ability of processed limestone products to return to their original chemical form is key to their effectiveness. In the lime cycle, carbon dioxide from the atmosphere or industrial processes reacts with hydrated lime, converting it back to limestone. Graphenstone paints utilise this natural process to absorb CO2 as they cure (the majority occurring within the first 30 days following application), contributing to air purification and environmental sustainability.
Incorporating Graphenstone’s CO2 absorbing paints into your projects not only enhances the aesthetic and durability of your spaces but also actively contributes to a healthier environment. By choosing these innovative lime-based paints, you are supporting a sustainable future and promoting better air quality in your living and working spaces. Explore the benefits of Graphenstone’s environmentally friendly paint solutions and join the movement towards a greener, cleaner world.
