While drywall sandpaper is ideal for sanding joint compound and plaster, it is not suitable for the initial sand skimming process. Sand skimming requires applying a thin layer of joint compound or plaster to create a smooth surface, and drywall sandpaper is too abrasive for this purpose. It may remove more material than necessary, resulting in an uneven surface.
Alternatives to Drywall Sandpaper for Sand Skimming
Instead of drywall sandpaper, professionals typically use specialized tools like a taping knife or a drywall trowel for sand skimming. These tools allow for precise application of the joint compound or plaster and help achieve a smoother finish without the risk of removing excess material.
The Final Sanding Stage
Once the initial sand skimming process is complete and the joint compound or plaster has dried, it is necessary to perform the final sanding stage. This is when sandpaper, including drywall sandpaper, can be used. The purpose of the final sanding stage is to eliminate any remaining imperfections, such as minor ridges, bumps, or uneven spots. Drywall sandpaper can be an effective tool during this stage, as its abrasiveness can smooth out the surface further.
While drywall sandpaper is not suitable for the initial sand skimming process, it can be used during the final sanding stage. For the initial application of joint compound or plaster, it is best to use specialized tools like taping knives or drywall trowels to achieve the desired smoothness. However, for achieving the final flawless surface, drywall sandpaper can be a valuable tool. Always keep in mind to choose the appropriate grit size of sandpaper for the final sanding, ensuring a professional finish for your sand skimming project.
