EcoMortar Premixed natural hydraulic lime building mortars

St Astier Natural Hydraulic Limes (NHL)

Premixed mortars for building, rendering and finishing in a variety of colours

See: COLOUR CHART

The absence of cement, ashes, gypsum and other pozzolanic additions together with its other qualities, make EcoMortarhighly suitable for repair and conservation work on traditional, vernacular and historic buildings. In new build the properties of EcoMortar will allow joint free construction, dispersion of condensation and will accommodate small settlement movements.

Ecofriendly characteristics:
- High vapour exchange qualities
- Produced with lower energy than cementitious mixes
- Re-absorption of CO2 in curing
- Will not deteriorate timber
- Possibility of recycling the materials used in building
- Elimination of painted finishes

G granulometry from 3mm to 0.08 for pointing, dubbing out, first and main coats on renders and rough finishing coats. For bedding mortars (10mm joints) use type CG.
F granulometry from 1.18mm to 0.08 for fine joints work, plastering and smooth finishing coats on renders. Available in a wide range of colours. When used as a finishing coat make sure that the backing coat is straight, dry and sufficiently hard to accept the finishing coat.
For Roughcast and Harling coarser granulometry is available on special order.

Packing: 35 kg. Bags
Preparation: in ordinary drum mixers (mix for about 5 minutes) Water addition: EcoMortar G : 4.0 litres - 4.5 litres per bag of 35 kg EcoMortar F : 4.5 litres - 5.0 litres per bag of 35 kg.

Application: on clean and dry background not water proofed. Dampen adequately dry or high suction surfaces. Protect against strong rain, frost, drying wind or direct strong sun until sufficient hardening has occurred. See "Protecting Lime Mortar".

Application by spray gun: possible. Please consult us. See also: "Applications & Good Working Practices - Working with Ecomortar"
