Osmo WR Base Coat (4001) is an exterior wood preservative that require protection against blue stain (EN 152), wood rot (EN 113) and wood-destroying insects (EN 46). It can be used on most exterior wooden surfaces including windows, frames, roller shutters, doors, pergolas, trellis and garden furniture.
Wood to be protected must be dimensionally sound and stable and not in direct contact with the ground.
Always do a test area before starting any project to check suitability and compatibility. Stir well before use. Osmo WR Base Coat is ready to use and does not require thinning.
Please Note: This product is not for use on wood which comes into direct contact with food or animal feed. Also not for use in living spaces or habitable rooms. Do not use in immediate proximity of any kind of water.
The product is a very good one which is appropriate for the job of protecting the wood without destroying its natural look. Its performance in UV screening and waterproofing the wood finish is all that was expected of a product of this quality.
Again aplied with a foam roller for speed - went in good and deep !
Fine. No problems to apply. Container was covered in German writing. I need a translator to decipher what was said on the tin.
i found this rather thin,so care should be taken in its application.
The Osmo base coat is easy to apply by brush and soaks into the wood for first stage protection. You must put a top coat of an oil based product on top (I used the Osmo UV protection oil on cladding that I want to retain the colour of) but the base coat is the right first stage treatment.
After spending hours researching which wood preservative to use I decided on Osmo WR4001 with a clear top coat for my log cabin. The product is easy to apply. Only concern is every where on the internet states a single coat but the tin states for best results 2 coats. Purchased from wood finishes direct who offered an excellent service. They were very informative and helpful. I will definitely be using them to purchase my top coat.
Easy to apply and completely colourless. Too early to say if it provides the protection promised.
Have not used it yet; am still rebuilding my decking. However using it as a base coat on my new decking should make be great for added longevity of the overall structure.
It is extremely runny so covering up any surfaces nearby is essential. It drys quickly but it is essential to have cleaned off any ingrained dirt before application as it will not soak through that! I am yet to see what the Osmo top coat looks like but having used Osmo products for several years I am sure it will look great
See my more detailed comments for Osmo Country Colour Dove Blue for a garden Playhouse project.
Provides the base to allow the finishing coats to do their job.
good product works well.
Went on well and the finished job (this base coat then the Osmo UV Protection Oil Extra) looks excellent. The door looks very good and it looks like it will be well protected.
If you use this under osmo paint, the finish lasts for 15 years, well so far.... Painted every 4 to 5 to refresh and the cabin is still perfect.
I have used a number of OSMO products over the years and have always found their quality to be excellent. Being easy to apply, low odour and giving long term performance value.
Look good at the moment, time will tell
Applied this before applying Osmo one coat only HS plus on to blasted hardwood bench slats to give them extra protection. Definitely need amount suggested as the wood does absorb it as you brush it on.
Ordered the quantity on the basis of the stated coverage rate. There is something wrong with the stated coverage rate i.e. it is far too low. As a result I ended up with twice as much as I needed. Annoying as it is not cheap.
Thank you for your feedback. The coverage calculators are there as a guide but many woods will take differing amounts. For example a rough sawn wood will absorb considerably more than a piece of wood sanded with a 240 grit sandpaper. And Pine will absorb more than Oak. There are many factors to consider, however if we find that this occurs more often we will get in touch with Osmo directly to discuss coverage details. If there is anything further that I can help with please feel free to get in touch.
All the Best Sam.
