RJ3.01   PURE LIMEWASHe

PRODUCT DATA SHEET

DESCRIPTION:

A traditional natural permeable paint for the internal decoration of lime putty plaster, soft brick, limestone, and porous building materials. It does not 'dry' like a modern paint but 'sets' by reaction with atmospheric carbon dioxide in the presence of moisture. Exterior grade Casein Limewashe should be used on less porous hydraulic lime plaster.

Environmental Consideations Limewashese are environmentally friendly products made with natural sustainable ingredients. They contain no VOCs, no petrochemical based ingredients, and no lead. Water-based.

APPEARANCE:

 Matt surface coating. Colours are darker in tone when wet.

COLOURS:

20 "C8" colours + White.
18 "Classic" C7 colours + 9 "Italian" C7 colours.

AVAILABILITY:

 5 litre and 15 litre. Limewashese are mixed to order, but can normally be supplied within 48 hours.

SHELF LIFE:

Pure Limewashe has UNLIMITED shelf life kept in sealed containers. Protect from heat and frost.
Note: Casein Limewashe has a limited shelf life.

COVERAGE:

 Approx. 4m2/litre/coat depending upon texture and porosity of surface.

HEALTH & SAFETY:

 Alkali pH 13. Eyes, open sores, cuts and skin must be protected. See Safety Data Sheet RJ 5.03A.

OBSERVATIONS:

Pure Limewashe is used for the decoration of internal porous surfaces. It should not be used on non-porous surfaces, cement renders, gypsum plaster, timber, or surfaces painted with anything other than limewash. Sample trials should always be carried out to assess compatibility with substrate.
Pure Limewashe should be protected from drying too quickly, and from frost before carbonation. It may brush off on clothes. For Internal Use Only.
Casein Limewashe (RJ3.02) adheres better to less porous surfaces. It is much less likely to brush off on clothes.

Coloured limewashes are made using natural earth pigments. Variations due to these pigments and differing porosity of surfaces are inevitable. Much of the charm of a traditional finish is its lack of uniformity with subtle variations of colour and tone.

PREPARATION:

Pure Limewashe requires a surface which is firm, clean, and porous. It can be applied to new lime putty plaster before it has fully dried and carbonated as the permeable nature of a limewash permits carbonation of the plaster beneath to continue.
Pure limewashe can be applied to previously limewash painted surfaces, but should not be applied to other paint types. Previously limewashed surfaces should be thoroughly brushed and washed with a wet sponge to remove dust, dirt and all loose chalky material that is removed readily. Any algae or mould must be treated with an algaecide or fungicide and thoroughly washed off with clean water. Do not use proprietary fungicides containing water repellents. Make good and fill with a compatible filler.
Pure limewashe must be applied to damp surfaces. Lime plaster, porous stone and brick must be thoroughly moistened with a mist spray prior to application.

APPLICATION:

 Pure Limewashe must be thoroughly mixed, preferably with a mechanical whisk, to ensure even distribution of pigments and ingredients immediately before and during use. Limewashing can be messy, and floors etc. should be protected. Protective clothing and goggles must be worn and great care taken especially when limewashing ceilings. Surfaces must be damp. Porous pre-wetted surfaces will need mist-spraying during application to ensure that the limewash does not dry too quickly. Apply the limewash to the damp surface using a brush, not a roller, working it into any cracks. It is applied in thin coats - limewash appears transparent on application and care must be taken to avoid thick build-up which will craze on drying out and may obscure detail. Normally, 3 coats are required, occasionally more. Each coat must be protected from drying too quickly by regular mist-spraying, and a reasonable time (normally at least 24 hours) allowed between coats. It is important to re-moisten the previous coat with a fine mist spray prior to the application of the next coat.
