Primer is an important step in all painting projects, although sometimes neglected. Primer is essentially a layer of material, covering stains or discolored points on surfaces. It also works well in hole-sealing and provides a consistent adhesive base for paint.
If you skip the primer, you will likely need more coats for sufficient coverage. However, the results may not be satisfactory as the result may turn out patchy, and the paint may not stick as well to the original surface.
Nowadays, the market offers an array of primers, and the question is how to choose the best one.
