The majority of HMG paint and powder products have a 12 month shelf life from time of delivery when
stored in original sealed containers in appropriate dry conditions (40–75% relative humidity and
15–30 °C) regardless of batch number/date of manufacture. There are exceptions to this statement as
some products have a six month shelf-life from date of delivery such as Crystalseal and HMG
Concrete Sealer for example.
Further information and specific product shelf life can be found on individual product Technical
