A system for distributing liquid coatings such as epoxys and urethanes onto a substrate base. The system includes a hose for transporting the liquid coating material from a storage container to a spray gun. A heating element within the hose heats the liquid coating material to facilitate transport and distribution of the liquid coating material. The heating element contacts the liquid coating material and can be activated by electrical resistance heating or by other techniques. By placing the heating element directly in contact with the liquid coating material, long line cooling losses are avoided, and heating energy is efficiently transferred to the liquid coating material immediately before distribution. Sensors along the hose length can monitor the liquid coating material temperature at different positions, and heating control over different hose sections can be controlled to efficiently accomplish optimum liquid coating material temperature before the liquid coating material is sprayed. Two part liquid coating materials can be separately transported through distinct, internally heated hoses and combined with a mixer at a position near the spray equipment.
