Wooden floors can be among the most beautiful features of your house, providing a natural, organic and permanently fashionable floor.
Because you want to keep them that way, you will naturally want to take action when you see signs of damage or decline. Issues like warping are caused by excess moisture from below and need the underlying problem addressed, but dents and scratches are problems you can tackle directly.
The big question is whether sanding is the best way to fix surface damage of this kind. The answer is that it is sometimes, while on other occasions there are alternatives.
For example, Homebuilding.co.uk advises that the best time to sand a floor is when the surface is generally in good shape but is dull or has scratches and dents. It also creates a new surface that can absorb colour, so it is the right thing to do if you want to stain it, as well as to smooth it before adding a new coat of paint or varnish.
However, it noted, stripping the wood may be required if there are several layers of paint or varnish, or if there are some features that could be lost through sanding.
There are other considerations too, such as whether you have a solid floor or an engineered wood floor, as the latter is a thin layer of wood and can only be sanded a couple of times, so if you can find an alternative, this is wiser in that situation.
For example, it is sometimes possible to fix dents made by furniture or high heels using water. This involves taking a wet cloth, rinsing it slightly, placing it over the dent and then running a steam iron over the cloth.
What this process does is cause the wood fibres to absorb the warm water, which then evaporates as the heat rises. This soaking causes the fibres to expand, reversing the contraction applied by the weight that caused the dent. Thus the dent pops out.
Sanding can be a very effective way of fixing problems and preparing the surface for a new coat. But it is not always the best or only solution.
