Concrete flooring is very practical in some areas of the house. But like expensive floorings, a concrete floor should be regularly cleaned and smoothened out. This can be done by sanding. Sanding is a lot of work and time-consuming, which is why if you want to do this yourself, you have to be really ready. To make sanding a little more bearable, this article will guide you through.
- Remove all furniture items. You need to clear the entire area before sanding, so move all items to the room closest to the area you need to sand. This can exhaust you physically, so do this a day before you intend to sand. It is best to have some help.
- Clean the floor. After clearing the area, take some time to remove as much loose dirt and debris as you can from the floor. Do this by either sweeping or vacuuming. Then continue on by mopping the floor with Trisodium Phosphate (TSP). Mix 1/8 cup of TSP with a gallon of water and a quart of bleach. Then dip the mop into the cleaning mixture and run it on the entire floor. Do this repeatedly if necessary. Wait for a few days for the floor to completely dry.
- Begin sanding. You must sand the floor in stages. Initially, you have to sand using 50 to 80-grit sandpaper. Your goal here is to level the pitted areas as much as you can. Run the sandpaper or power sander on the entire floor area, focusing on the uneven parts. Remember to sand only in one direction. You might have to repeat sanding around five times or until the floor is smooth. Change the sandpaper if necessary.
- Switch to a fine sandpaper. At this stage, you can use a finer sandpaper, preferably 300 to 700-grit. A fine sandpaper will gradually enhance the look and feel of the floor, making it even smoother and shinier. Following the same direction, pass the entire area with the sandpaper or sander.
- Do the final sanding. Your concrete floor is now more appealing. But to create the best possible finish, you have to sand one last time with a very fine sandpaper. At least 1,500-grit will work. Again, run it on the entire floor area, making sure not to press it too hard against the floor. After the final sanding, your concrete floor will look shiny and polished.
- Apply floor polisher. Not only will a polisher improve the floor’s finish, it will also protect it from dirt. So make sure to use a polisher after sanding. Then finish it off by buffing. If you prefer, you can also stain your concrete floor. This, of course, will take extra days to complete.
Use a pair of protective eyeglasses and mask when sanding your concrete floor to prevent dust particles from going into your eyes and nose. Use gloves as well, especially if you are sanding with your hands. Also, wear comfortable working clothes, so you can freely move your body. Sanding is a physically demanding job, and resting once in a while is necessary to prevent fatigue.
