Hamstone
Orange-yellow Jurassic Somerset limestone dried, crushed, sieved.
Additional information
Our Hamstone Dust is a premium, crushed limestone aggregate sourced directly from the iconic quarries of Somerset. Renowned for its distinctive warm, honey-gold hue, this dust is an essential component for any conservation professional or homeowner looking to achieve a seamless aesthetic match with traditional Hamstone masonry.
Unlike synthetic pigments, using genuine Hamstone dust ensures that your lime mortars and renders possess the same geological DNA as the host stone, maintaining both the visual integrity and the breathability of the building.
