For doors, vents, windows, and some other things you can’t move ensure to protect them with plastic sheets and secure them with painter’s tape so that they won’t be covered in dust.
Make use of pliers to get rid of any staples or nails. If you notice any loose wooden boards, make sure to nail them down appropriately. Inspect the floor for some minutes to look out for any existing damage. Deal with any observed scratches and holes with a putty knife and wood filler.
Allow it to dry completely and then wipe the floor with a dampened cloth to get rid of dust and the uneven surfaces. Apply a hardwood cleaner to the floor for thorough cleaning. After you are done cleaning, let it dry fully before proceeding.
- Put on protective equipment
Before going deep into the work, your safety is important. Wear your goggles, dust mask, gloves, and earplugs to protect yourself from dust and noise. Sanding results in a lot of debris in the air, increasing the risk of inhaling hazardous pollutants. Open your windows to allow sufficient ventilation and a great means to disperse the dust.
- Use the right sandpaper
Next, choose the right sandpaper for your orbital sander. Refinishing an old hardwood floor will require you to remove old stains, paint, or varnish. To effectively do that, you will need fairly coarse sandpaper. You need a minimum of 20-grit sandpaper to remove paint and a minimum of 36-grit sandpaper to remove varnish and shellac.
You will be able to use finer sandpaper, like 100-grit sandpaper as you proceed to finer finishing. So, ensure to get ready various types of sandpaper for this task.
- Sand the floor
You are now at the stage of doing the real work. First, attach the sandpaper to the orbital sander. For the first stage of sanding, start with the coarsest grain, that is, 30 to 40 grains. Make use of finer grain sandpapers as you proceed with the stage of sanding to achieve the smoothest finish by the end.
You will need various kinds of sandpapers based on the previously applied finish on your wood floor. For example, you will require 20-grit sandpaper to remove the finish if your hardwood floor has a top coat of paint. Varnish on the other hand needs 36-grit sandpaper.
Now, position the orbital sander on your floor to align the grain along the length of the hardwood boards. Do not angle the sander so you won’t end up having marks on your floor. Select the point of the floor you will start sanding based on the shape of the room. You can decide to start at the center of the room.
While sanding, move the sander in a similar way to a lawnmower. Carefully sand the wood patch by patch without leaving any area unattended to. You can go over the same patch many times to get an even and smooth surface.
- Vacuum and Mop the floor
Sanding a hardwood floor generates a whole lot of dust in the air. Before you can go ahead and finish the floor, cleaning the floor is a necessity. Get a good vacuum to suck up all found dust. Then, thoroughly mop the floor or use a damp cloth to wipe away the residue.
- Seal and finish the floor
Technically, a good hardwood floor does not need to be sealed. But, leaving your floor exposed especially in the face of high traffic would dull your wood floor quickly. If you are sealing your wood floor, make use of an oil-based polyurethane sealer for the hardest-wearing surface. You can go with a water-based sealer for areas with limited traffic.
You can apply the sealants using a paintbrush or a high-density foam roller. Work with gloves to avoid skin irritation. Allow the sealant to dry for about 48 to 72 hours after spreading them evenly on the floor.
How long does it take to sand a floor with an orbital sander?
It takes about 2 to 4 days to sand a hardwood floor with an orbital sander per room as opposed to 1 to 2 days with a full sanding kit. If your floor is flat and in good condition, it might not take up to that time.
