Mortar in paper sack for group arrangements

Mortar to create cable and combination insulation in solid walls and ceilings. Suitable for pumping, pressing and for manual installation. Adding approx. 6 litres of water to 20 kg of dry mortar produces about 20 litres of workable compound.
In dry, frost-free rooms, the dry mortar can be stored for at least 12 months in closed original containers.
