A hot melt applicator heats and maintains a joint sealing material within a precise temperature range by first flowing the material through coils located in a heat exchange bath where the material is brought to the intended temperature and viscosity. The coils convey the material to a storage tank maintained at this precise temperature range wherein the material resides for a period of time sufficient to remove certain entrapped gases such as air. Thereafter the material is dispensed to its intended area of use. The dispensing means may comprise a hose arrangement maintained within the prescribed temperature range by heat exchange coils which use as its heat exchange medium, fluid from the heat exchange bath.
