Tarmac Buxton Lime and Cement has made two additions to its White Peak range of traditional lime products.
The first is Natural Hydraulic Lime (NHL), which can be used to produce lime mortar for internal and external work. It combines the traditional benefits of lime with a relatively fast set and early strength. NHL will set in damp conditions, and sets further over time. Products are available ranging from mortar classes 1-4 for internal work, external pointing and render and masonry building in sheltered areas to mortar classes 7-10 for work in exposed areas such as chimneys or copings and below the damp-proof course.
The second, a lime putty, is designed to produce slower-setting lime mortars, plasters and renders. This allows for small movements of buildings before the final set. It is suitable for restoration and conservation work, and no water is needed.
