Hardwood Floor Buffers

Not to be confused with hardwood floor sanders, buffers used by professionals are Hardwood floor buffer used for several purposes. This is not a machine that can effectively refinish a floor. Instead these oscillating machines (run in a circular motion) are used more after final drum or belt sanding has been done. They are also used between finish coats.

Smooths Out Drum Sanding Roughness

For example; a red oak floor has been drum sanded with progressively finer grits starting at 60 and up to 100. Next comes the floor buffer that runs in a circular motion. Prior to the first coat of finish, professionals insert a new screen to smooth out any sanding patterns the bigger machine has created. Though they are not highly visible at this point, they will become magnified with the application of any finish without using this process.

Screening Between Finish Coats - Improves Finish Adhesion

Floor buffing machines are also used between finish applications. Once any finish coat has cured (will vary on type of finish and relative humidity) the machine is brought to the floor again; this time to smooth out any roughness (photo above) from the first finish coat. The first will always be the roughest feel as more liquid is absorbed into the grain. In this step a used screen is often used that will create less noticeable swirl marks. An added purpose of the screening procedure is to improve finish adhesion.

Disc machines run at low speeds, typically in the 175 RPM range. Many machines do not have dust collection equipment with the dust concern being valid, but will not be

as troublesome from what the drum sander creates. For any type of work performed with these machines it’s always recommended to consult with the manufacturers finish specifications as some will vary from others.

Not Easy To Operate At First

In some cases floor buffers are also used for stain application, but should really be left up to a professional. These machines can take some getting used to for those with no experience. When starting they’ll often kick or pull to one side or the other. Our suggestion is practicing with a buffer pad if you’re so inclined to use one. Simple suggestions such as starting with the handle at waist height. Raising the handle will move the machine to the right, while lowering will bring it to the left.
