Coverage

Roundtower have been manufacturing lime putty (non hydraulic lime) since 1999, initially for the restoration of Cor Castle.

Although traditionally this type of mortar was used internally and externally, today it is generally used for internal plasterwork & cornice etc, pointing, bedding and renders in sheltered areas.

Roundtower lime putty has been allowed to mature for at least 1 year before being tubbed into 20kg tubs. Storing the lime putty in airtight containers allows the putty to mature and any un-slaked particles will have sufficient time to slake. The longer the putty is allowed to mature the better the finished product. Traditionally in Italy the best quality work was carried out using lime putty allowed to mature for generations.

The best method of manufacturing a lime putty based mortar is to mix the ingredients in a mortar mill. The resulting mortar is of a high quality and very workable. No extra water should be necessary during the mixing process.

Lime putty offers the best flexibility and breathability of any lime mortars.

Roundtower lime putty is used to manufacture lime wash, traditional lime mortars and plasters.

We supply lime putty in 20kg tubs. It is also available in ton bags.

We are happy to manufacture specific lime putty mortars for a project should this be required.

The production of lime putty is a hazardous procedure and should only be carried out by suitably trained personnel. This is not a procedure to be carried out on site where the work cannot be monitored and controlled.

Health and Safety – Lump lime (calcium oxide) is a caustic alkaline. When it comes in contact with eyes or skin, it will cause a chemical burn. Wash the affected area with a solution of sugar water immediately and seek medical assistance. When working with lime the operative needs to wear personal protective equipment (eye protection, gloves, overalls and dust mask).
