Interior Painting Guide Coating systems for normal exposures

This table will help the specification writer select the best detailed specifications for normal exposures such as schools, hotels, apartments, stores, etc. as well as light, moderate, and heavy duty industrial specifications.

It has been designed from the specification writer's point of view; starting with the information the specifier has—the material and the surface. The specifier can choose the coating’s generic type, the finish desired, the surface preparation necessary, the appropriate primer, and the number of topcoats necessary to achieve a satisfactory coating system.

Surface preparations as shown are minimums and should be upgraded if necessary because of the service or environmental conditions. For additional data on the indicated surface preparation, turn to pages 2 through 4.

Note: standard alkyd and epoxy coatings will chalk on exterior exposure.
