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
