Ready to use Factory prepared hemp fibre re-enforced fat lime skim plaster with mineral aggregates. The material is lightweight, has good coverage anti-splash and good bonding characteristics.

The material is suitable as a finish coat over ‘Hempire Scratch Coat’ on internal surfaces.

Milled and finely screened whole hemp, high calcium lime, mineral aggregates and water supplied as a pre-formulated paste which requires some agitation before use.

A solid light weight fibre re-enforced material combines masonry and organic qualities. The material has good breathable, insulating, thermal mass, flexible and hygroscopic qualities.

20 kg bags, 250 kg tubs and 1000-kg pallets.

Can be stored for up to 1 year in air sealed package. Seal bags for re-use.

The product undergoes an in-house monitoring, using a quality management system which conforms to current international standards.

Applied manually using steel plastering trowel. Spray gun can be used but superior finish achieved manually. Use only clean water without admixtures.
Use an electric hand mixer and mix thoroughly before application.
Can be applied at thicknesses of 3-8 mm.

Internally only: Use steel float for fine finish.

Do not apply below 5 degrees centigrade. Maintain temperature above 5 degrees centigrade in winter months.

Use only Hempire Lime Wash or other breathable paints. See Slaked Lime Putty sheet.

Suitable for a wide range of substrates. Background to be stable and dust free. Highly absorbent surfaces to be dampened beforehand.

Internally: Care most be taken to reduce humidity during drying phase. Provide adequate ventilation or heat and de-humidification. Failure to provide ventilation can lead to temporary surface mould growth.

High humidity and non-absorbent substrates will increase setting time.
Plaster benefits from working and compression with steel float.
Lime is a caustic material with abrasive mineral components: take care to protect finished surface from lime staining and scratching by covering and/or cleaning as work progresses.
In renovation work mineral staining may sometimes occur. In this unlikely event consult a painting expert to achieve a breathable finish.
In renovation work, strip non-breathable renders from wall, rake out non breathable pointing, provide adequate drainage around building and ensure breathable floor is installed to avoid forced migration of rising damp in walls. Where adequate steps have been taken allow time for walls to gradually dry out.
Do not not use in damp basements.
