Roman Stucco premixed render

Lime green Roman Stucco is based upon Roman cement, a traditional binder invented around 200 years ago. Using this, we have created Lime Green Roman Stucco, a contemporary product that sets rapidly, with a fine texture and an innate strength which ensures it can be cut, carved and shaped with remarkable detail. It is suitable for matching historic “Roman cements” including the repair and replacement of decorative mouldings, cast elements and plain render.

Coverage Approximately 1.7kg per mm of thickness over 1m². One 25kg bag will cover approx. 1.45m² at 10mm thick. This does not include any allowance for wastage..

Application guidance

Application: onto clean and dry background, not water proofed. Repoint masonry as required with the correct mortar. Adequately dampen dry or high suction surfaces beforehand, for best adhesion apply a slurry of neat natural cement and water prior to application.

Each coat must be applied to the previous once while the previous is still damp working "fresh on fresh". Typically leave no more than 2 hours between coats.


Mix in drum mixers or by mixing whisk. Carefully add clean water, between 4.5-5 litres per 25kg bag and mix for approximately 5min. Prompt mortar will rapidly set, typically within 30 - 50 mins, depending on temperature. Do not use in temperatures less than 5 ºC or over 30ºC.

Please note these are not stock items and have to be ordered from the factory, which may incur a 10-14 day lead time
