See: COLOUR CHART
The absence of cement, ashes and other pozzolanic additions together with its other qualities, make EcoMortar highly 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.
- 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
