Limestone is the raw material at the core of the Graphenstone range. We use lime made in wood-burning kilns, producing remarkable whiteness and purity with the same method as the mid-nineteenth century. The lime cycle is 100% natural and produces a paint base with unique qualities. Lime is highly alkaline with a pH of 12, ensuring it is profoundly antibacterial. Graphenstone paints are therefore naturally proofed to fungal growth, mould and bacteria - no more dark spots in the corners of bathrooms and kitchens. Even insects won’t land on our paint. In addition to minimising mould, the lime cycle is also a powerful tool for air purification, soaking up harmful gases and controlling humidity. Resultantly, Graphenstone paints help to maintain superb indoor air quality that alleviates allergies and battles bacteria.

For exterior paints such as masonry paint, Graphenstone’s nanotechnology edge brings a host of advantages in durability and finish. The graphene infusion ensures our paints are uniquely elastic and flexible, so they are much more resistant to cracking than ordinary exterior paints. Graphenstone masonry paints are so elastic; they can stretch to accommodate for heat expansion/contraction that may cause hairline cracks in other paints. Graphene also brings remarkable abrasive durability to Graphenstone exterior paints. Thanks to this, they’re the first ‘Class 1’ strength natural paints in history. This refers to their performance in the classic quality control ‘Rub Test,’ which determines how long a coating lasts under constant rubbing stress. Graphenstone external paints, therefore, have unmatched resistance to external weather conditions and are also far more washable paints. We provide a 5-year guarantee for all exterior paints but expect a far significantly longer life span. Our oldest case studies - the Cathedral de Panama, for example - have gone a decade without needing repainting.
