The Cuprinol brand is generally our first choice among paints and stains for the garden area, but not this time! Although it is still a great choice of different colours compared to the Ronseal brand, it just does not stand up to the test of time.

The Types Of Decking Treatments

With many decking oils available on the web or in your local DIY store, it pays to use an oil that’s right for your boards.

If you have new hard/softwood boards, then all the oils and stains featured in this article will work wonders and finish your project perfectly.

For older boards, then we would only recommend Ronseal because it soaks deep and will make your decking boards last longer! But, always make sure you have followed our guide to restoring your decking boards.

Decking Stains

Seem the most popular type of decking preserve but not always the best option!

If your decking boards are new and have never been varnished/stained before then, we would suggest decking oils.

But if you’re looking to top up protection or change the appearance of your older boards, then stains are the next best thing to using oils.

Decking Board Sealers

This type of wood protection will cover the outside of your boards and will seal your decking boards against water and the elements.

This option is less attractive because it will not show off the grain of the wood, which can be more appealing depending on the types of boards you have installed.

Decking Board Oils

The most undiscovered protector, generally people will cover their boards in stains and nonslip paints. But, using the best decking oils will make your boards stand out much better.

Oiling your boards bring out the grain and give your timber a more natural look.

Oil is absorbed deep into the boards, making them water-resistant and much better protected against all weather, especially in the UK.

What To Use When Oiling Decking Boards

The Application Options
The Application Options

There are a lot of gimmicks sold in local DIY stores in recent years.

If you’re looking for advice from an experienced decking installer, then we highly recommend you use an excellent natural brush.

Yes, it may take longer to cover the boards, but you will end up with a far better finish. Sprays, rollers and sponge devices will make your work look sloppy because you will get pools of product between the groves.

Oiling New Decking Boards

Decking Restored!
Decking Restored!

When you oil or stain your new decking boards for the first time, you must always:

  1. Clean any debris and sawdust
  2. Make sure all screw heads are below the surface
  3. Let your hardwood decking boards lay for a few days
  4. Softwood decking boards are ready to be treated straight away
  5. Let both hardwood and softwood boards dry out before oiling

These are straightforward tips to follow, but, if you treat decking boards when they are wet or even damp, they will not absorb the oils! When you have followed the simple advice above, then take your time and do not carry the whole tin of decking oil around with you, because mistakes happen.

Decant some into a jam jar or smaller container and dip your brush in making sure you do not drip any oil. Plan your method and oil every board individual until you move onto the next one.

Decking Oils FAQ’S

How often should I oil my decking?

Initially, you should oil your decking board 3 or 4 times. Once you have given your decking boards their initial oil, we recommend every autumn to keep them looking new.

Can I oil old decking boards?

Yes, once you have sanded and cleaned the boards, they will be ready for oiling. Make sure you apply 2 to 4 times on timber raw boards.

Can you use oil on both hardwood and softwood decking?

Yes, oils are great for both hardwood and softwood decking boards although hardwood boards will need a few coats initially because the timber is more compressed than softwood making it harder for the oil to absorb.

Should I oil the underneath of the boards?

If this is possible without unscrewing the decking boards then yes, this should have been done before the installation of the decking boards. But, if your restoring a decking project then you could unscrew the boards and oil the underneath. This will preserve them more making them last longer.

Can I use a roller to apply decking oil?

Yes, a roller will cover the decking at a quicker rate when compared to a brush. Although be sure not to let the oil puddle in the groves on the top of your decking boards.

  1. I have just had new decking boards installed on my old decking frame! The other boards have become rotten after about 6 years! The decking become rotten because of the pool chlorine I believe! Will the decking oils you have mentioned in this article waterproof against chlorine? Thanks

    • Hey Ziggy,

      Yes, these decking oils will protect the boards against chlorine in the water! They are great at sealing the boards and making them totally waterproof. If the boards are going to be wet for longer periods I would suggest applying these oils on a monthly basis.

      You should also seal the underside of the boards. This is because they can rot from underneath upwards.

  2. I use to just use a floor varnish for my decking boards but they deteriorated very quickly. I have now oiled them with Ronseal after following your guide on restoring old decking boards. I would like to thank the advice and recommendation I received from Wezaggle!
