Drymix Coarse is suitable for general building and pointing work applications where the joint and bed size exceeds 10mm. Explore Drymix Medium for laying blocks or bricks with smaller joints. Appropriate for various project types, including conservation, renovation, or sustainable construction.
Drymix Coarse prefers masonry with a degree of suction, so masonry units such as engineering bricks may be more challenging to work with.
A 25kg bag will produce approximately 15 litres of mortar and fill roughly 1.5m² of joint. The width and depth of the joint will influence this estimation. On-site trials are advised for the best yield indication for your specific project.
