At A Glance...

  • Ideal for use on new oak and tropical hardwoods – perfect for dense wood species
  • Penetrates the wood fully and protects from within
  • Extremely thin oil which saturates the wood, literally feeding it from within
  • Easy maintenance – no sanding or stripping
  • Replaces the natural oils lost from the wood and will not blacken the timber
  • Suitable for interior and exterior use

Deks Olje D1 is a saturating wood oil which feeds the wood to replace lost oils. It drives out any moisture and air present in the wood and fills the pores with oil. This enriches and stabilises the wood to provide long-lasting protection to both interior and exterior timber. It does not form a film on the surface of the wood but protects from within so it will not peel or crack. Deks Olje D1 is a clear oil which gives a clear matt finish enhancing the natural beauty of the wood and it is easy to maintain with no sanding or stripping.

Deks Olje D1 has been optimised for dense, oily and difficult to impregnate woods and can be used on horizontal and vertical surfaces. It provides protection against humidity and its effects as well as against damage from UV rays. If applied in marine environments it can be applied both above and below the waterline. It can also be used as a primer for conventional singles pack coatings and decorative finishes. For an intense high gloss finish topcoat with Deks Olje D1 with Deks Olje D2.

Always read the Deks Olje D1 Technical Data Sheet before using and follow the instructions carefully.

Surface Preparation

Surfaces must first be clean, dry and free of dirt, grease, grime, mildew and previous coatings. Treat any mildew with a 50/50 bleach/water solution. Scrub the solution on to the surface and allow it to stand for 10-15 minutes. Then rinse thoroughly.

After stripping and cleaning, allow the wood to dry for 2-3 good drying days before applying Deks Olje D1. D1 may only be applied to bare wood surfaces or a weathered wood surface that was previously finished with Deks Olje D1. All other finishes must be completely and thoroughly removed first. If necessary sand the surface after cleaning and/or stripping (100 grit paper).

New wood

Interior – Sand wood with 100 grit paper to open the pores, dust off and degrease the surface with methylated spirits.

Exterior – Prepare as for interior wood or treat the surface with Aquanett and then neutralise with Net-Trol.

New wood surfaces have a hard shiny surface called mill glaze that prevents maximum penetration and bonding of any finish; sanding or treating the wood with Aquanett removes this, ensuring maximum performance of the finish.

Weathered wood surfaces (untreated)

Clean weathered wood with Net-Trol, to remove the loose wood fibres, dirt and other surface contaminants. If the wood is severely contaminated, clean it with Aquanett and neutralise with Net-Trol.

Previously oiled surfaces

All other oils or sealers must be completely and thoroughly removed with Aquanett and stripped surfaces neutralised with Net-Trol, before applying Deks Olje D1.

Previously coated surfaces (Paint, Stain, Varnish, Waterproofers)

All previous coatings must be completely and thoroughly removed with Dilunett and stripped surfaces neutralised with Net-Trol before applying Deks Olje D1.

Note: Hardwoods including exotic hardwoods and woods rich in tannins (i.e. Cedar, Douglas Fir, Teak, Ipe) may darken with Aquanett and Dilunett. Neutralising with Net-Trol immediately after rinsing will lighten and restore the woods colour.

Application of Deks Olje D1 saturating wood oil

The secret of Deks Olje’s success lies in its saturation of the wood to bring about an even ‘matt sheen’ finish when dry. Start by applying Deks Olje D1 to an area that can be treated in about 15 minutes. As soon as the 1st application has penetrated (normally 15-30 minutes), apply a 2nd application. Then continue applying D1 ‘wet on wet’ until a uniform, overall saturation of the wood is achieved. The number of applications needed depends on the wood.

DO NOT allow Deks Olje D1 to become dry or touch dry between applications. Leave the final application for 30 minutes, then wipe over the surface to remove excess and puddled material with a rag soaked in Deks Olje D1 and rung out so that it is damp to the touch. If necessary occasionally ring out the cloth to keep it damp. It is important that as much D1 as possible is applied on the first day.

Deks Olje D1 must be kept ‘active’, this is done by the ‘wet on wet’ applications and the continual brushing over of the area, which assists and helps achieve maximum penetration. D1 has high penetration; its place is in the wood and not as a surface coating. Allow 3 days for D1 to set-up and dry, before use or in marine uses before putting the boat in service or continuing with Deks Olje D2. Temperature is of very little importance when applying D1.

Clean Up

Clean all tools and equipment with white spirits while still wet. If allowed to dry, remove with paint stripper. Wipe up any drips or runs immediately with a cloth soaked in white spirits. Dried Deks Olje D1 may be removed with Dilunett. Store and maintain equipment as directed by manufacturer.

Note: Any rags, steel wool etc. soaked in D1 may spontaneously catch fire if improperly discarded. Rags, steel wool etc. must be saturated with water after use or placed in a sealed, water filled metal container, before disposing of it with household waste.


Regular washing with Net-Trol will help to maintain the appearance of Deks Olje D1. It will gradually lighten over time due to exposure to the sun and UV rays. When the wood has lightened to a light grey colour, it is time for a maintenance application. Clean the surface with Net-Trol and then apply Deks Olje D1 until the wood is saturated and the finish restored, usually 1 or 2 applications will be sufficient.


Deks Olje D1 may soften some caulking. If in doubt consult us. The tannins and natural oils in woods such as Iroko impede the penetration and drying of finishes. These species of wood should be thoroughly prepared or allowed to weather for 12 months before applying Deks Olje D1. Contact us for preparation advice. If using on plywood – contact us first. Do not use Deks Olje D1 on thermo treated wood.

Things to Remember

  • Cover everything you do not wish to paint.
  • Apply between 5˚C and 35˚C.
  • Do not apply in direct sunlight or on to hot surfaces.
  • After spray application, always back-brush or back-roll to improve penetration and uniformity of coverage.

    Brilliant product! It does everything it says on the tin and more. So easy to apply and the finish is wonderful. Balcony railings look great. Can’t wait for some decent weather to be able to prepare and protect my balcony decking.

    Used on a 7 yr old ipe deck, cedar trellis and teak garden table, last cleaned & oiled several years ago, so were grey, weathered and dry. Seems an excellent product – happy with result. Not quite returned to original colours but good result considering. Covered more surface area than estimated. Pricey but worth it. Excellent delivery service with updates. Applied after using the net-trol cleaner (also excellent).

    On my ten year old IPE deck I was able to strip ten years of old oil etc with a two Part cleaner and then apply Deka Olje 1-. So much better than any other oil – very fine oil to penetrate the wood, not coat the wood. Easy to apply with a paint pad – great finish and also
    Most efficiently delivered next day – thank you

    We use a lot of different oil products in our joinery shop, and this is one of the better ones… does exactly what we expected and needed for a hardwood casement window build, with rich protection offered to the timber. We first used this product around 4 years ago on another window job for a house on the South Coast, and it still looked terrific when I saw them again 2 weeks ago.

    Used D1 on the inside of my log cabin walls. First removed the mill glazing by light sanding. Than applied a layer of wood preserver. Applying the D1 was a pleasure. Went on well with a brush and absorbed just fine. Used a foam roller to apply D1 on the wooden ceiling. It did take some 4 – 5 days for the smell of drying to be one but the results are great.

    Well worth the money, used to oil tropical hardwood deck, beats anything else on market for coverage and penetration

    I’ve used a lot of D1 on my garden furniture and it gives an amazing result. Has utterly transformed all my hardwood furniture and they look beautiful.

    You do have to make sure that you prepare the surfaces correctly using the right chemicals (dilunett / netrol) and that you leave the wood to dry properly before the D1 goes on and then leave the D1 to dry properly for at least 3 days out of the weather. I budget an approx 5 day end to end schedule for the whole process with much of it waiting for the wood to be ready. If you rush it you will not get the results you want.

    You also have to make sure that you get as much D1 into the wood as you can and that does take time but it is SO worth the effort.

    I will always use this product and I’ve also used Textrol which gives the softwood furniture an equally good finish.

    Deks Olje D1 – Wow a product that is fit for purpose! Thank you for bring this wonderful product into my life. I feel a little of an idiot really, clearly boats are often made using wood and I am a scuba diver, so to look for a product made originally for the marine world should have occurred to me sooner. Having tried and been thrilled with your metal rust conditioner, when I saw the oil was the same brand, I had the faith to try and wow its fantastic. I would tell anyone – YES BUY THIS PRODUCT ITS WONDERFUL and I kind of look forward to doing it again – how often can you say that! Now I am going to try the paint remover for anything but aluminum (Dilunett), I imagine I will be happy to finish that job no matter what. Lastly, thank you to the very nice man who confirmed if it says suitable for anything but aluminum I can assume its suitable for steel :).
