Assessing The Floor Before Sanding

Before performing any sanding operation, the condition of the floor must be assessed to ensure it’s in a condition suitable for sanding operations. This may entail assessing vertical movement at end-matched boards or joints, the gapping at the board edges, signs of any moisture, the degree of cupping in the boards and if there are any indicators of high moisture content. Any issues spotted should be put in writing and provided to the appropriate personnel so that the right course of action can be taken.

Preparing for Sanding:

Punching Protruding Nails And Filling Nail Holes

Before the sanding process can actually commence, make sure that all the nails on the floor are punched at least an inch below the surface of the floor boards. Any nail that’s not properly punched can potentially damage your sanding equipment and derail the sanding process as well. Punches nail holes can afterwards be filled with an oil or non-oil based filler. An oil-based filler may bleed oil into your timber and consequently affect the color of the wood surrounding the nail hole. Moreover, the color of the hole filler should be carefully selected so as to reduce any visual impact on the filler used.


Prior to sanding, the floor needs thorough cleaning to ensure that it is free from grit, debris and dirt. If not removed, these particles can cause deep and uneven scratching on your timber floor surface thus requiring extra sanding to remove. To begin with, the floor should first be swept followed by intense vacuuming with more attention to floor sections that are not effectively cleaned through sweeping such as corners or window sills.

It is essential that you remove any materials that could potentially impact on the floor coating or sanding process. Extra care should also be taken with the silicone-based sealants that could have dropped onto the floor. These products could be widely spread during the sanding process thus compromising the bonding between the timber and its coating.


During the entire timber floor sanding and finishing process, it’s important that access to the area of work remain restricted. Any trades working around or in the section can wet the floor, generate dust, walk over the floor, introduce silicone based sealants and essentially contaminate it. Clear instructions must be given to the occupants or owner regarding the access of the area and opening of windows that could blow dust over the sanding area.
