Sanding a wood floor will involve a number of steps. It is important to follow these steps because it is easy to mess up and having to spend more than what you had earlier planned. Following these steps will help in avoiding some common problems people encounter when sanding the floor. These steps are to guide you throughout the process; however, hire the professionals Floor Sanding Brisbane – Floor is safer.

Determine the grit sequence

Refinishing a floor will mean sanding the floor many times. People doing this for the first time think that you just use one grit of sandpaper over the floor one time and they are done. Sanding will take at least four passes, with each having a finer level of sandpaper. The most difficult part of this process will be determining the perfect grit starting pass for your floor.

Assess honestly, sand appropriately

One mistake that many people make when sanding for the first time is timid sanding. This is where the floor that has been sanded looks dingy because the sanding was not aggressive enough. You will need to do an honest assessment that will enable you to know the amount of work needed. Knowing it will make it easier to accept that time and effort is needed.

Floor Sanding Process

Grit testing

If you think that your flooring is in good condition, consider testing using a 36-grit belt on the drum sander and use it on a small area (choose an area that is not in good shape) If the floor is in bad shape, consider testing with a 24 grit. If it doesn’t work, try out more aggressive combinations until you find the ones that will give you clean wood when you reach 36-grit.

Choosing your Abrasive

You will need around four sanding passes, but you have flexibility on the abrasive you will be using for the first one. You should choose a small area and see how the grit you are starting with performs. You will then increase the grit because the more you increase the smoother the surface sanded. You should always remember that 60-grit and 80-grit were designed to remove the finish – its role is smoothing out scratches.


The next process is sanding the floor, and you will need to start with the drum sander. Use the edger to sand areas that the drum could not reach. You should use the same grit whether you are using the drum or the edger. Once you are done sanding, vacuum or sweep the rooms that have been sanded. Repeat this using different grit until you achieve the smoothness you are looking for, and this can sometimes be more than four times. You should finish with 100-grit if you are planning to stain the floor or if the surface you are sanding is maple.

Finally, use a buffer or pole sander over the surface at 100 or 120-grit. This will put a uniform scratch pattern on the entire floor surface.

The above process is simple, following it will go a long way.
