The joy of osmo oil – let’s do wood some good!
This article about the uses of Osmo oil for treating wood, was written by Traditional Painter for Stafford, Martin Dunn. As a former college lecturer and assessor, he has a great deal of indepth information to share.
Osmo oil on interior timber, worktops and furniture
Over the last couple of years I have been using more and more Osmo oil on interior timber, worktops and furniture. The product I turn to the most is the polyx-oil original interior wood finish, which comes in both a clear satin matt and matt finish plus tinted versions (more later).
It’s a hardwax oil which combines all the advantages of oils and waxes in one product ie it goes on like a traditional varnish or oil but gives the appearance and durability of a wax. It is resistant to water, dirt, wine, coffee etc and is microporous, so will not crack, peel or blister. I think a lot of people will know it as a natural wood floor finish.
At the moment I have been using the rapid version of the polyx-oil which is touch dry after 2-3 hours (dependant on conditions) and re-coatable in aprox 6 hours. The original needs overnight drying.
The property I have been working on has just had a loft conversion, and because of regs needed fire doors fitted on all the stairs and rooms leading off from it. They also fitted a new bannister and spindles which the customer wanted matching to a piece of furniture.
How to apply Osmo Oil to new timber doors
1 – The bare timber doors receive a first coat applied with a slightly worn natural bristle brush (don’t use a new one, you will spend most of your time picking bits of bristle or the tip ends, the flags, from the applied osmo oil). You could also use a synthetic brush or even a painting pad, but I prefer natural bristle for this.
2 – I DO NOT sand any wood until I have put the 1st coat on and let it dry. The reason for this is two-fold. I don’t want to scratch the bare timber because the product will raise the grain when applied, so I ALWAYS rub down after the 1st coat to remove any nibs and flatten the raised grain. (Remember to follow the grain of the wood when rubbing down and use either a fine sanding pad or some 240 grade finishing paper.)
3 – The second coat is applied – and thats it!
No thinned primer coats; no 3 coats to build it up; no top coats of wax applied by rags or mops when finished.
The bannister and spindles received 2 coats of matt woodstain in antique pine, followed by 2 coats of Osmo Oil. As I said, the client was trying to match the new installation to some existing furniture.
Different sheen levels for clear finish on timber
The customer went for a satin matt finish in the Polyx Oil, but it is available in a matt finish as well. If you wanted a totally flat matt finish, I would probably look at the Polyvine products which have a “flatter matt” finish.
Coverage of Osmo Oil
It only needs 2 coats to bare timber, and goes a long, long way! To give you an idea, on the stairway there were 10 doors – both sides had 2 coats – plus the bannister and spindles. The first coat, being on bare timber, soaked up more product than you would expect if oiling a previously coated surface, yet all this work was completed with just 2.5 litres of Osmo Oil!
Osmo Oil for worktops
As a specialist kitchen painter, I also offer clients additional options for upgrades, and Osmo do a specific product called “Top Oil” for worktops, which I have successfully used. So, after stripping existing coatings back to the bare surface, I apply 2 coats in the same way as described above for doors. It needs to be left overnight to dry between coats.
Osmo Oil for slate, tiles and furniture
Osmo Polyx-oil can also be used on slate and non-glazed ceramic tiles as well as furniture. It also meets European regs for safe use with children’s toys, plants and animals ( although I don’t think they would look that good coated in wax??!!!)
So with this product, we can get away from traditional “brittle” varnishes and wood stains (Like I said, they do a tinted wax oil too, for interiors.)
Osmo oil also offers a natural alternative to other wood treatments such as linseed oils, danish oils, teak oils and the highly effective but often overlooked tung oil – they all still have there uses though.
Osmo oil – Not just for floors.
Paints and Interiors are Osmo stockists and we are very impressed with the product knowledge of Ben, the owner. The overall level of service is also top drawer, from advice to orders to delivery, so well worth dropping in online, if you are in the market for Osmo wood care products.
(See other Trade Corner associate suppliers, like Paints and Interiors.
These are a select group of companies we know professionally and can recommend wholeheartedly to Traditional Painter readers on the basis of their exceptional service and ethos.)
