40-100/50 PMB must be heated before use. For best results, use a heating kettle with an indirect heating system such as hot oil. Ensure that 40-100/50 PMB doesn’t exceed 200°C and that the oil does not exceed 230°C. When hot, pour either from a watering can or direct from the melting kettle via a pressure fed heated hose with a special nozzle. The 20kg cardboard kegs are not suitable for placing on or over direct heat (i.e. gas or wood fire).
For a 40mm vertical joint face and a 2mm coated thickness of 40-100/50 PMB: 0.08kg of 40-100/50 PMB seals approximately one linear metre of joint or a 20kg pack seals approximately 240 linear metres of joint. For overbanding, apply at a rate of 0.5kg / m2
