A closer look at Neptune

IsoGuard®’s a timber treatment oil that we developed to help protect your wood from spills and marks without masking its natural texture and character. Put simply, it makes life better for your furniture, and hopefully for you too. Any exposed timber (in other words, unpainted) in our collections will be finished with IsoGuard®, whether it’s flooring, indoor or outdoor furniture. But you’ll need to top it up every few years.

How it works

IsoGuard® doesn’t just coat wood – it penetrates the surface and bonds with the fibres, acting as a barrier against anything that might stain it. It can repel water, and most other household liquids from wine to cordial, and leave the surface unblemished, but only for a time (up to four hours). It’s tough, but not bombproof.

The finish

Because IsoGuard®’s almost invisible, your wood still looks and feels as though there’s nothing there unlike most varnishes and lacquers - just like the version for indoor wood. It’s more breathable though, so it’ll adapt to protect outdoor furniture in different weathers. And it has a UV filter to stop timber from fading in the sun.

How to use it

Applying IsoGuard®’s easy - each tin comes with clear instructions, so you’ll know exactly what to do and when. For more on how IsoGuard® works, have a read of our detailed guide.

Just so you know

Always throw away your used IsoGuard® cloth by dunking it in water and putting it in an airtight container while it’s still wet. Leaving an IsoGuard® cloth unwashed, in direct sunlight, or putting it straight in the bin can lead to spontaneous combustion.
