Sanding hardwood floors is a multi-step process. Although none of the steps are rocket science, you should follow them carefully for getting a nicely finished hardwood floor. Let’s explore the step by step process for sanding hardwood floors.
For refinishing a hardwood floor, you will have to sand over that floor multiple times. You need to sand the floor at least four times using a finer level of sandpaper each time for getting a smoothly nice hardwood floor. So, the first step to take is to determine the sequence of the grit of the sandpaper.
Unfortunately, there is no fixed sequence of grits because every floor is different. You have to choose the sequence according to the condition of your floor. There are 7 different sanding grits for sanding floors, but you will not need all of them for your floor.
Now, the choice of your initial grit should be determined by the condition of your floor. However, you should start with the 36-grit if you’re confused about the condition of your floor. If it does not work, go for the coarser grits gradually.
Drum sanders are the most effective sanding tools for sanding wood floors. Use the drum sander to sand all the part it can reach on your floor with the initial sandpaper grit you determined to use for sanding hardwood floors.
Use the edger to sand all the edges that the drum couldn’t reach using the same grit you used with the drum sander.
After sanding with different grits, vacuum the floor every time you change the grits. Otherwise, the pieces of sanding grit paper will make scratches again and again. These coarse particles can ruin your sanding with the finer grits of sanding discs.
After vacuuming, use the drum sander again with the finer grit according to the sequence of grits you determined in the first step.
Use the edger again to sand all the edges that the drum couldn’t reach using the same grit you used with the drum sander for sanding hardwood floors.
Don’t forget the step 4. Every time you change grits, you must vacuum. Then repeat steps 5 and 6 until you have reached the 80-grit sandpaper.
If you still feel that there are some scratches left on the floor, sand them with the 100-grit sandpaper to get a smoother floor.
There will be some places that are still not sanded because the edger is round and you cannot reach the corners with it. You can use carbide scrapers for sanding the corners but they are expensive. Carbon steel scrapers will save you some money and they work well if you sharpen them after using. You can also use sanding sticks to sand the corners of your floor.
Even if you work for hours, don’t forget to check for scratches or edges. Even though you used the 100-grit, you may miss some tiny part of your floor. So, check it again.
Use a clean, lint-free textile to remove all the dust from the floor. You can also use a dry microfiber cloth to clean the surface.
Sanding hardwood floors is not an easy task. However, it won’t seem much difficult if you follow the above-mentioned steps carefully. Sanding wood takes a lot of concentration. So, being attentive is also necessary to be able to follow the steps for sanding hardwood floors.
