M120 – ALL-ROUND MORTAR Product
The range of applications for the Jahn M120 is what gives it its name but it is particularly suited for levelling rough and slightly damaged surfaces, sealing hairline cracks in stony substrates and for modelling work.
As with all Jahn mortars, M120 is a mineral-based, single-component mortar that is supplied ready to mix with water. It has a porous structure and is high frost, moisture and salt resistant.
Benefits:- Can be applied on all mineral, stony, absorbing and load bearing structures
- Multi-purpose
- Ready to use – no one site chemistry leading to inconsistent repair
- Environmentally friendly – no toxic or synthetic components
- Salt and moisture regulating
- Non-shrinking
- Easy to apply
