Light Sanding Wood Floor and Re-varnish

The essence of floor sanding work is removing the top layer with all the dirt, grime and small damages, so that a fresh layer of wood is revealed underneath. However, the whole process is a lot more and is usually done in several stages.

Floor repairing

Before the actual sanding takes place, the floor needs to be inspected and any loose or damaged floorboards made good – re-fix loose boards with headless nails and replace broken ones (we usually use reclaimed timber that matches the colour of your floor).

Gap filling

Although not a must, most people opt to have this done, as it gives equal finish to the floor. The other benefits of the gap filling is that it insulates the floor and prevents dirt build-up between boards.
Small gaps (up to 5mm) are usually filled with a mixture of resin and dust from the initial sanding. Although the most cost-effective method, this is also the shortest to last, since, once the mixture dries, the resin shirks with time and either falls below the boards, or you vacuum it out.

The more expensive, but also the longer lasting method is to seal with timber fillets that are cut to size and glued into position. As fillets move with the boards during seasonal expansion of the wood, this repairing method can have your floor filling last for decades.

Wood floor sanding

This is usually also done in stages – a coarse grade sand paper is used to strip away old sealant and paint, then a finer grade sanding papers, to give the floor a smooth and even finish and prepare the floor for sealing. With the professional machinery we use, sanding is nearly dust-free.


Another optional operation – a staining can give your floor the desired looks – whether all-natural or a colour that matches your room’s décor. Stains are now produced environmental-friendly and completely safe


Whether you chose to stain the floor or not, it will require finishing with a protective sealant. This also comes in different choices – varnish or oil.
Varnish (laquer) is usually applied on heavily used floors, as it is a durable sealant. However, since modern varnish is made of polyurethane (which is, basically, liquid plastic), it will eventually crack and peel.
Oil is manufactured from natural materials. Unlike the varnish, which is applied ON the wood, oil penetrates into the timber and doesn’t crack/peel. It is easy to maintain and can be re-applied when needed, without having to sand the floor anew.

Note that wood sanding is also applicable for wooden counter tops.
