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

The material is suitable as an insulating foundation coat on internal and external surfaces.

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

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 10-20 mm.

Internally: For textured finish, finish with steel float or for smooth mat finish use Hempire Skim Coat.
Externally: To finish apply Hempire External Render, Hempire Lime Wash and Hempire Weather Coat. See also Hempire External Render System sheet.
Apply second and subsequent coats as soon as base coat is firm.

Use only breathable paints internally and externally.

Suitable for a wide range of substrates. Background to be stable and dust free. Highly absorbent surfaces to be dampened beforehand. Use mesh and fixings on smooth board surfaces.

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.

Externally: Avoid work below 5 degrees centigrade. If winter work is essential, close in work area by erecting scaffold, membrane, and thermostatically triggered heating to maintain a temperature  above 5 degrees centigrade. During hot dry weather use water liberally on substrates and finished plaster to prevent crazing and re-work with wooden float.  When plastering on breathable boards, take extra care to avoid board becoming saturated prior to application.

Use bell cast at base and drip-line above openings.
High humidity and non-absorbent substrates will increase setting time.
Plaster benefits from working and compression with wooden/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. 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.
Artisan finish can be achieved by hand see website.
Do not not use in damp basements.
Do not use within 150 mm of outside ground level.
