Description
Properties
- Made exclusively from natural hydraulic lime (NHL)
- Compatible with old masonry
- Highly water vapour permeable
- Free from calcium sulphate
- High adhesion
Areas of Application
- External & internal -
: First stage harling coat to stabilise and homogenise the masonry substrate prior to levelling with Secil Reabilita Cal RB
Coverage
- A 25 kg bag will make up 16 litres of mortar when mixed with water to the consistency for harling (5 litres of water per 25 kg bag). This gives coverage of approximately 5 m² at an average thickness of 3 mm
