Prompt Cement

Key Features & Benefits:

• Extremely Rapid Setting: Sets in minutes, ideal for rapid repairs, casting, and creating sharp architectural details. The set time can be controlled with the addition of a citric acid retarder.
• Authentic Historic Finish: Provides the warm, variable beige/ochre tones characteristic of original 19th-century renders and stuccos.
• Highly Breathable: A high vapour permeability allows the building fabric to breathe, preventing trapped moisture and ensuring the long-term health of the structure.
• Sympathetic to Old Masonry: Its lower strength and greater elasticity make it the perfect partner for softer historic bricks and stones, avoiding the cracking and spalling caused by modern cements.
• Natural & Sustainable: Fired at lower temperatures than Portland cement, it has a lower carbon footprint and contains no plasticisers or synthetic additives.
• Incredibly Versatile: A single material for a multitude of tasks, from renders and plasters to pointing, bedding masonry, and marine applications.

Ideal For:

• Restoring or creating external stucco and render on Georgian, Victorian, and Edwardian buildings.
• Running in-situ architectural mouldings like cornices, string courses, and window surrounds.
• Rapid repairs to historic stone, brickwork, and masonry.
• Pointing soft or delicate brickwork and stonework.
• Applications in damp environments such as cellars, basements, and marine construction.
