Osmo Wood Protector (4006) is suitable for any interior wood particularly susceptible to blue stain, including wooden flooring, window frames and wooden panelling in moist environments, such as bathrooms. It is also suitable for exterior wood for which an absolutely ecological, biocide-free impregnation is desired.

Please Note: Osmo Wood Protector is compatible with all commonly used glues and putties with the exception of products containing Silicon.

Please be advised that the 125ml tins are printed in German only. For application instructions refer to the Application section below.

Ensure the wood surface to be treated is clean, dry and frost-free (moisture content max. 18%).

New Wood

  1. New smooth or freshly sanded wood can be degreased with white spirit if required

Old Wood

  1. Old paints and lacquers must be completely removed
  2. Remove any surface traces of mould, algae or moss with a scraper or stiff brush
  3. Treat areas affected by mould, algae and moss with a suitable mould and mildew cleaner
  4. Clean old microporous (oiled) finishes thoroughly by lightly sanding and wiping down with white spirit
  5. Fill small cracks, larger joints or holes with a suitable Osmo wood filler

Always do a small test area before starting any project and follow the manufacturer's instructions on the tin at all times. Stir thoroughly before use and periodically during application. If possible, apply the first coat to all sides of the wood before installation to offer the best all-round protection.

  1. Apply Osmo Wood Protector thinly and evenly along the wood grain with a Osmo Soft Tip Brush, Osmo Premium Microfibre Roller or a lint-free cotton cloth
  2. Apply to all sides of the timber before installation where possible
  3. Allow for good ventilation whilst drying

Osmo Wood Protector is designed as a pre-treatment before the application of an Osmo interior finish or Osmo exterior finish. Any top coat (except One Coat Only or Fence and Garden Stain) should be applied within one week of using Osmo Wood Protector (4006).

Please note: Water-based stains and other water-based products cannot be used on top of this product.

If it does what it should do I will be happy by Stephen

As per instructions used this as the first coat because my doors lead into kitchen area and this product is recommended. Also used this on all the other doors to keep them the same shade in case the wood oil did not darken the same. Easy to apply but keep room well ventilated.

Easy to apply and doors the job by Neil Wilkinson

Water beads on the worktop now instead of soaking in and leaking marks. Makes a massive difference around the sink. I put 3 coats of top oil on after.

Second time purchasing this - very happy again! by Mr GRB

Not much to say really - works great in conjunction with what ever tinted hard wax oils your using. I usually apply the Hard Wax Oil first then once it's dried and been used for a few weeks then sand in the direction of the grain very lightly to key the Hard Wax Oil finish then apply a thin coat of the Wood Protector - works great!

So far so good by Liz Ch

Used this as a 1st coat on oak worktops around the sink and window areas. Blended in to 1st coat polyx on other areas. Topped with polyx for 2nd and 3rd coats. Used to prevent blue bkack staining which can happen to oak if water penetration. Have to say the way the polyx has finished the surface, theres a totally waterproof finish anyway, so they don't appear to have needed this, but only time will tell....

Great stuff by Jamie Cross

First time using this product, it darkened the oak more than anticipated which may be down to my lack of research however it does give a great colour and protect well as I've already found out!

Just the job for my wooden ceiling airer by Jane B

As always, the Osmo products are brilliant. A little goes a long way so although expensive to buy you get a lot of coverage.

Only time will tell if this protects my brand new oak drainer against rot. In combination with Osmo Top Oil my oak drainer should last forever -- I'll let you know how its looking in 10 years.

Nice addition to the range by Pete

Very different from Polyx Oil. Different formulation - presumably better suited to protection. Final finish with Polyx oil on top was excellent.

Was recommended to me i would recommend to anyone by David Crease

the best... honestly. was recommended to me by a carpenter of 30 years. now having used it i can say it is better than danish oil, or linseed or any other worktop oil you care to try. my builder was also really impressed with it. goes on perfectly. now the wood shows zero signs of marks since using this. excellent.

Easy to apply and so far seems to be doing its job by Sue Hilton

We were renovating our 15 year-old oak butchers block kitchen worktops which were looking very patchy. The area around the taps behind the kitchen sink had gone black owing to the amount of water which had splashed on to it and then soaked in over the years. Having sanded it all down that area still looked slightly darker than the rest but applied 2 coats of the wood protector hoping that it would stop any further damage. We then applied 2 coats of Osmo Top Oil 3058 which enhanced the worktop without making it too dark or orangey. The area behind the sink still gets splashed but the water just stays on the top and can be wiped off so not penetrating the wood. Really pleased with the result.
