How to Sand a Wood Floor like Professional Timber Floor Sanders and Polishers

Would you like to polish and sand your floor just like professional timber floor sanders and polishers? We know your answer will be a big YES. Well, let us tell you that in this blog we are going to tell you that secret, no matter whether you have hardwood, softwood, herringbone parquet or strip board floor there are some simple basic guidelines that you must follow to get professional results when sanding a wooden floor.

First of all, preparation is vital, ensuring all the staples or nails are punched down will give a much better appearance and result but will also reduce the risk of sparks getting into the dust bag creating a fire hazard. What sandpaper to start with? Dependent on the condition of the floor (commercial or domestic environment) it may be required to start with a coarse grit such as a 24 or 36, you must, however, check the composition of the floor! Some wooden floors are termed engineered which means there is a real wood layer on top of a cheaper ply or softwood backing, the top layer can vary dramatically from 1mm up to 10+mm which means you must be careful when using coarse sandpaper not to go through the top layer of real wood.

Once you have determined the composition and condition of the wood floor you will need to start the sanding process using the correct grade of sandpaper. It is the success secret of most of the professional timber floor sanders and polishers.

If you are sending a strip floor that seems a little uneven work on a 15-degree angle from left to right along the grain of the timber, this will give you a flatter finish to the floor as you move through the grit ranges. Make sure you walk at an average pace when using a belt sander, too fast and the drum will not have enough time on the floor and too slow will result in an uneven cut. Having completed a 36 grit pass with the belt sander the next grit to move to will be a 50 grit (never jump more than two grit ranges!), you should now alter the angle that you passed on the previous grit, try 10 degrees the other way whilst still moving left to right.

Once the edges and corners are completed, now get ready for the final passes of grits on the belt sander. It would be recommended to pass with an 80 grit sandpaper, you will be running along the grain of the boards now to obtain a nice smooth finish. Once completed a final pass with the 120 grit to ensure a beautiful ultra clean smooth finish to your floor.

Now you have done wood floor sanding it is important you vacuum the floor prior to polishing, please make sure not to scratch the floor with the vacuum.

Your choice of finish should be decided on the type of traffic over the floor, is it a commercial or domestic environment and what the maintenance of a wood floor entails dependent on the finish. Lacquer is a popular finish with a lot of variants, also oils, wax oils and anti-slip finish in sensitive areas.

We hope that by practicing the above guideline you will be able to do it like a professional.
