Match the volume solids of the paint to be applied with the desired dry film thickness to get the theoretical spreading rate

Note: These values are calculated for a coating appled to a perfectly smooth and non porous substrate. Actuall values may be significantly lower depending on the porosity and profile of the substrate.
