In this video Jay from Wood Finishes Direct will explain what to consider before buying  Osmo Door Oil.  

Door Oil FAQ 

Can I use a wood oil on my interior veneered doors? 

Products such as  Osmo Door Oil (3060) have been specially designed for use on veneered internal doors. It gives interior doors a tough, durable, clear, satin finish. Always check the door manufacturer’s guidance before treating veneered doors as in some cases, it may invalidate the warranty of the door. 

Looking for advice on how to treat Oak veneer doors? 

Interior Oak veneer doors can be treated with either a wax, oil or varnish. Using a clear  door oil will enhance the natural grain and character of the wood, they will also slightly darken the wood to give it an almost damp-like appearance. Using a clear wax such as  Fiddes Supreme Wax Polish will keep Oak veneered doors looking natural but offer less protection than oils and varnishes against scratches and scuffs. 

For durability, varnishes offer the best protection. For ease of maintenance and repair from minor scratches, scuffs and scrapes, we recommend using a door oil or wax. Always check with the door manufacturer’s guidance before applying a finish to a door. 

Before you Buy – Osmo Door Oil transcript.  

Hey I’m Jay from Wood Finishes Direct. In this video we will be highlighting what you may wish to consider before jumping into finishing your doors with Osmo Door Oil. A little tip for you, it is so much easier to finish a unhung door with all handles and other furniture removed and any size adjustments made, Trust me, you’ll thank me later!. So, Grab your door and follow me. 

Firstly, what is Osmo Door Oil? A highly durable, professional grade, protective finish made from natural oils for all softwood and hardwood internal doors. Suitable for solid wood, engineered and veneered doors.  

Not all doors are made the same, the doors you typically will be looking at finishing will either be engineered or solid wood. What’s the difference? Well, Solid wood doors are exactly that, made from a solid piece of wood. Next engineered or veneered doors are made around a core of an engineered non-natural material, typically MDF with a real wood thin layer over the top.  

We’ll start with a very handy little test called the water test. The logic behind this test is simple, it helps us establish whether the door is bare or previously treated. All you need to do is apply a drop of water onto the door and leave it for 30 seconds. If the water beads, then the wood contains an existing finish. If the water soaks completely you can move straight onto application! It’s genuinely that easy. 

For engineered doors like the one in front of me, they typically come unfinished and ready to go. So normally I’d recommend giving them a light rub down with a finishing pad to help smooth out any rough areas from the laminate. Do be careful around edges with sandpaper as you can, if too rough wear though the veneer, and no one wants that. 

With a solid wood door that’s been previously finished its best to sand through the grits up to p120, and always with the grain. Properly executed sanding makes all the difference when finishing as this will not only remove old finishes but open the grain so the oil can penetrate and protect the door fully. The results from improperly sanded surfaces? This ranges from patchy finishes to swirl or scratch marks. Of course, both of these results aren’t a catastrophe as you can always sand and refinish. 

Over application isn’t uncommon with Door Oil but is avoidable by using the P.A.R.S.E. Method 

Prepare properly – sand the wood to P120 

Apply thinly – always working with the grain 

Remove excess – using a microfibre cloth 

Sand lightly – abrade the surface with a finishing pad once dry 

End coat – Apply and leave to dry 

Nice and easy 

Osmo Door Oil comes in two variations, the Satin 3060 that enhances the grain and offers a soft sheen and the Raw 3033  that helps maintain an untreated look that looks great on Oak. Doors in rooms such as kitchens and bathrooms can be treated with Osmo Wood Protector 4006 for additional protection prior to oiling. This base-coat is only recommended for use on doors being treated with the clear-satin door oil. The base-coat will enhance grain to some degree which goes against what the Raw is designed to achieve.

Interior wooden doors top tips on care and maintenance 


  1. I have an old leaf dining table which looks to have solid timber legs and border around the table edge. The top has been veneered with a nice looking grain. The leaf has had little use so shows the deep rich colour it had when new. It looks like it had a varnish finish. I can easily remove the varnish on the leaf and most is already gone from the rest of the top.
    However is Polyx®-Oil suitable to finish thin veneer? I know it will be great for the legs and border. But not sure about the best treatment for the veneer.

    • Hi Allan, I would recommend a small test area with the Polyx on the veneer as it can soften the glue and delaminate the veneers. If the veneers are ok after the drying time then it hasn’t affected the glue. Hope that helps!!

  2. Hi,

    I have purchased Jeld Wen Mackintosh doors that are oak veneer as well as some other doors that are not branded. I also purchased osmo raw oil but am hesitant in applying this to the doors as I have read oil can delaminate the veneer.

    Please can you advise me on how to protect my doors, should I use stain or oil? What will be best for my kitchen and bathroom doors which are also oak veneer?

    I look forward to hearing from you.


    • Good Afternoon,

      Thank you for your enquiry. Veneered doors are shrouded in vagueness. The main reason for this is the type of glues used to bond the fine veneers onto the core of the door. Some door manufacturers use water-based glues and some manufacturers use solvent-based glues. It is important that when you receive your doors that you follow the manufacturers guidelines as to what they recommend for finishing.
      The manufacturers carry out extensive testing on their veneers to ascertain what type of product can be used. If a product is used that is not recommended by the manufacturer this can lead to the softening of the glues and delamination of the veneers.

      If the paperwork that you receive with the doors states that you can use a penetrative oil please consider this one;

      If the paperwork states that you can only use a water-based product then please consider this one;
