Something important to remember whenever painting ceilings, walls or any paintable surface:
- All unpainted surfaces must ALWAYS be primed.
- Priming previously-painted surfaces are handled according to the topcoat selection and will be required, depending on the existing paint coating on the surface / substrate.
Here are some basic rules to remember:
Repainting a previously-painted surface which has been painted with a water-based paint:
- Enamel Paint – depending on the condition and quality of the water-based paint used before, a primer may be required because low quality paints may need consolidation with a penetrating primer.
- Water-based Paint: No primer or undercoat needed.
Repainting a previously-painted surface which has been painted with an enamel paint:
- Enamel Paint: No primer BUT undercoat required.
- Water-based Paint: No primer BUT undercoat required.
