Drywall is a popular building material that is used in construction to create walls and ceilings. When installing drywall, it is common to use sandpaper to smooth out any rough edges or uneven surfaces. However, choosing the right grit sandpaper can be confusing. In this article, we will explore what grit sandpaper is best for drywall and why.
What Grit Sandpaper is Best for Drywall? The grit level of sandpaper refers to the number of abrasive particles per square inch of the sandpaper. The lower the grit number, the coarser the sandpaper, and the higher the grit number, the finer the sandpaper. For drywall, the recommended grit range is between 120 and 220.
120-grit sandpaper is the coarsest grit that is recommended for drywall. It is ideal for removing excess joint compounds and smoothing out rough surfaces. However, it can leave noticeable scratches on the surface, which is why it is recommended to follow up with finer grit sandpaper.
220-grit sandpaper is the finest grit that is recommended for drywall. It is used for smoothing out any remaining rough patches and creating a smooth, even surface. It is also ideal for removing any sanding marks left by coarser sandpaper.
Why is Grit Size Important? Using the wrong grit sandpaper on drywall can cause damage to the surface. Using too coarse of grit can create deep scratches that are difficult to repair while using too fine of grit can result in a surface that is too smooth and does not adhere well to paint or wallpaper.
It is important to start with a coarser grit sandpaper and gradually work your way up to a finer grit. This process helps to ensure that all rough patches and imperfections are smoothed out while avoiding unnecessary damage to the surface.
Conclusion When it comes to sanding drywall, choosing the right grit sandpaper is essential for achieving a smooth, even surface. For the best results, it is recommended to use sandpaper in the range of 120 to 220 grit. Starting with a coarser grit and gradually working up to a finer grit will help to ensure that all rough patches and imperfections are smoothed out without causing damage to the surface. By following these guidelines, you can achieve a professional-looking finish for your drywall project.
