Selecting the correct abrasive paper is crucial for achieving a smooth, paint-ready surface on gypsum board. This material, typically made with aluminum oxide or silicon carbide grit adhered to a paper backing, facilitates the removal of imperfections such as joint compound ridges, bumps, and uneven textures after installation. The choice of grit size, ranging from coarse to fine, directly impacts the final result.
Employing the appropriate abrasive paper offers several advantages. It ensures a professional finish, reduces visible seams, and enhances paint adhesion. Historically, coarser grades were initially used for rapid material removal, followed by finer grades to refine the surface. This technique, now standardized, significantly improves the aesthetic appeal and longevity of the finished wall or ceiling.
