Roman Stucco Exterior Wall Render

A fast setting Roman Cement based decorative render. Can be used in the repair and replacement of decorative mouldings and cast elements as well as plain rendering.

Stucco has been historically used as an exterior wall render to create highly detailed and decorative finishes on building facades, such as those on the many fine Regency houses of Cheltenham, Hastings and Leamington Spa.

Lime green Roman Stucco is based upon Roman cement, a traditional binder invented around 200 years ago. Using this, we have created 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.

These characteristics mean Lime Green's Roman Stucco is specified for high profile projects such as the refurbishment of Osborne House (Queen Victoria and Prince Albert's family home on the Isle of Wight) and the recent re-development of King's Cross in London.

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.
