Should I sand primer before painting? This is a question that often arises among both novice and seasoned painters alike. When embarking on a painting project, one might ponder the necessity of sanding the primer layer prior to applying the final coat. How does the texture of the primer affect the adhesion of the subsequent paint layers? Could it be that sanding promotes a smoother finish, allowing the paint to adhere more effectively? Conversely, is there a risk of damaging the primer, leading to potential complications in the painting process? Additionally, what type of sandpaper should be employed for such a task? Is it better to use a finer grit to refine the surface without compromising its integrity, or does a coarser grit yield more beneficial results? These considerations may greatly influence the overall quality and longevity of the paint job, prompting the need to carefully evaluate the pros and cons of sanding primer in preparation for painting.
