Theoretical and Practical Spreading Rates given below are also expressed in Square Meters per Litre and Litres per Square Metres.

Spreading rates can also vary with the type of application e.g. spray, brush or roller. Practical spread rates are determined by a loss factor which is affected by weather conditions, and the surface roughness or profile especially with spray application.

These spreading rates are equated against the given typical dry film thickness (D.F.T.).

Spreading rates must not be confused with coverage and therefore for costing purposes and quantities it is advisable that the relative Data Sheet be consulted to establish the required number of coats to be applied against the recommended film thickness.
