When it comes to refinishing hardwood floors, sanding is an essential part of the process. However, choosing the right grit sandpaper can be confusing, especially for those who are new to refinishing hardwood floors. In this article, we will discuss what grit sandpaper is ideal for refinishing hardwood floors and why it's important to choose the right one.
What Grit Sandpaper to Use for Refinishing Hardwood Floors?
The grit of sandpaper determines how rough or smooth the surface will be after sanding. For refinishing hardwood floors, the ideal grit sandpaper to start with is 36 or 40 grit. These grits are coarse and are used to remove the existing finish, stains, and scratches from the surface of the hardwood floors. The coarser grits also help to level out any unevenness or warping in the floorboards.
After sanding with the coarse grit sandpaper, the next step is to use finer grit sandpaper. For the second sanding pass, you can use 60 to 80-grit sandpaper to remove the scratches and marks left by the first pass. This grit range is also good for removing any remaining stains and finishes from the surface of the hardwood floor.
For the final sanding pass, use 120-grit sandpaper. This grit is finer and will help to create a smooth surface that is ready for staining or finishing. It is important to note that if you are staining the hardwood floors, it is recommended to skip the final sanding pass with 120-grit sandpaper. This is because the pores of the hardwood will close up, preventing the stain from penetrating and resulting in an uneven finish.
Why is it Important to Choose the Right Grit Sandpaper?
Choosing the right grit sandpaper is crucial when refinishing hardwood floors. Using the wrong grit can cause damage to the surface of the hardwood floors and can result in uneven sanding. For example, using grit that is too coarse can leave deep scratches on the surface, while using grit that is too fine will not remove the existing finish and stain.
Moreover, using the wrong grit sandpaper can lead to more work and expenses. If you use a grit that is too fine, you may need to sand the hardwood floors multiple times, which will increase the time and cost of the project. On the other hand, using grit that is too coarse can damage the surface of the hardwood floors, leading to the need for repairs or replacement.
Refinishing hardwood floors is a time-consuming and challenging process, but it can be rewarding when done correctly. Choosing the right grit sandpaper is an essential part of the process, and using the wrong grit can lead to more work and expenses. Starting with a coarse grit, such as 36 or 40, and progressing to finer grits, like 60 to 80, and finally, 120, will help to create a smooth surface that is ready for staining or finishing.
