Finishes: A Full Guide 

At Floor Sanding, we source the best quality wood floor finishes to ensure the longevity of your beautiful flooring. Our professional and experienced technicians will start by assessing the condition of the floor before taking action. Floorboards that are damaged will be removed and replaced using planks of the same wood species and colour. If we cannot find an exact colour match, we will use the appropriate stain to ensure it has the same hue as the rest of the wood flooring.

1. Sanding

To begin, the site must be clear to create enough space for the machinery. If certain furnishings cannot be removed e.g., large sofa, heavy cabinet etc., then they should be placed on one side of the room. Carpets and floor coverings must also be removed, and any loose nails should be secured or removed to prevent them from nicking the sandpaper or damaging the machines.

Once the room is ready, sanding can begin! We at Floor Sanding evaluate the grade of the wood before deciding on the grit of the sandpaper – this decision is very important to ensure the desired results are achieved. Sandpaper grit is labelled by number, where the higher grits represent smaller, finer abrasives that are used to create a smooth glossy texture. To simplify things, we have added a table with the key details.

In terms of selecting the appropriate sanding machine, our technicians will make that decision on the basis of the size and shape of the site, as well as and condition of the wood.

2. Gap Filling

To create a seamless appearance,  you may choose to fill any gaps that have developed in between the floorboards. This process is optional as some enjoy the character that gaps can give to a floor. If you do decide to fill in the gaps, several options are available: resin filling, solid wood strip and rubber strip. A resin filling involves combining sawdust gathered during the sanding procedure with a clear resin to create a paste. The paste is then administered using a small spatula. Alternatively, appropriately sized slithers of wood can be glued or nailed down to fill gaps or holes. Rubber strips are the least recommended method however they are also an option to consider. For a full, detailed guide please check out our Gap Filling page.

3. Staining

If you want to change the colour of your wood flooring, it is best to use a high-quality stain followed by varnish, as opposed to a coloured varnish. At Floor Sanding we offer a range of exciting colours to enhance and elevate the appearance of your wood flooring.

To apply a stain, simply add it to a rolling tray and use a roller to employ a thin, even coat. It is recommended to apply a total of 1-3 coats to deepen the colour of the wood. Please allow time for each coat to dry before adding the next. A dry rag can be used to absorb any excess product.

4. Finish

To complete the job, a lacquer varnish or oil-based finish is applied to create a protective layer over the wood floorboards. Lacquer and oil finishes are manufactured in a variety of sheens and colours. When deciding on which finish to use, it is important to take into account the style and level of protection you want to achieve. For stained flooring, a clear lacquer is best. To apply the finish, a clean dry rag or rolling brush can be used to apply thin, even layers. Again, ensure each layer dries before adding the next.

Another factor to consider is the gloss level of the finish. Once more, this is a personal style decision that our helpful and experienced technicians can support you with. We offer matte, satin, semi-gloss and high gloss finishes in clear and coloured hues.
