ZeroPlus Mortar is a mix of fine-ground sand, cement and other ingredients specific to Porotherm use:
• Mixed locally to laying, it allows for thin joints which still achieve full strength after 24 hours
• Unlike traditional mortar, which is often limited to use only when the temperature exceeds 3°C, ZeroPlus is able to be used from 0°C, allowing constructors to minimise weather related delays
• Each 15kg pack requires just 3.6 litres of water and will lay 1 No. pack of blocks when applied by roller
Ensure the first blocks are level, horizontal in both directions and ensuring there are no lips between the adjacent blocks. This is the most crucial stage of the process, as it determines the accurate alignment of each of the subsequent build storeys, and the speed and accuracy of the construction as a whole.
