Roundtower NHL 3.5 Grey & White

Roundtower NHL 3.5 White is a highly versatile, natural hydraulic lime binder, ideal for external plasterwork, rendering, pointing, and general masonry applications. With a clean, bright finish, it is especially suitable where a light or colour-matched mortar is required, such as on stonework, fair-faced brick, or decorative lime render finishes.

Produced to EN 459-1 standards, Round tower NHL 3.5 White provides a balanced combination of strength, breathability, and workability, making it the preferred lime binder for new builds, solid wall construction, and restoration projects where slightly higher strength is needed compared to NHL 2.
