Raised garden beds

How to treat wooden raised beds

Protecting your wooden raised beds from the harsh Irish weather is highly recommended to increase their longevity. To do so, there are a few simple and effective steps you can take.

Once your bed/s have been constructed, the best solution to offer the best protection is to treat them with a protective paint or oil finish. This will help to alleviate cracking and warping that occurs sue to weathering and UV rays.

You might decide to use pressure treated wood for your raised beds, which although does offer a little protection, will make little to no difference long-term. Regardless of the type of wood, we recommend you treat it.

Treating raised garden beds

Why would I use raised beds?

Using raised beds in your garden is an ideal way to either create interesting visuals for flowers or for splitting your garden up into areas for growing vegetables.

The best way to keep your beds looking better for longer is to treat them upon construction before filling with them with soil! If you are not constructing a new bed and already have one in your garden, we recommend removing the soil and cleaning the wood before application.

Using a high quality exterior wood treatment will maintain the integrity of the wood, ensuring a lovely space for plants and flowers to grow for many years to come.

How to treat wooden raised beds

We are proud to be able to offer a variety of products for exterior wood treatment. Some of our most popular are:


TextrolTextrol saturating wood oil enhances the natural beauty of soft and hard wood whilst providing a mildew-resistant finish. It has exceptional, long-lasting protection from the effects of moisture, weathering and UV rays.

Coats are applied wet-on-wet – meaning you save time as you do not need to wait for coats to dry during application.

As it is a saturating product, Textrol works by protecting the wood from within. This means there is no film on the surface of the wood and therefore will not peel or flake.


AquadecksAquadecks is a saturating, water-based wood finish that leaves a long-lasting, rich, matt finish suitable for use on hard and soft woods, as well as new or aged timber. It’s ready to use, dries quickly and has a low odour.

As Aquadecks saturates and stabilises the wood from within, it will not peel or flake.

It is available in 7 various shades and is easy to maintain with no stripping or sanding required. Simply clean the wood and apply a coat of Aquadecks.

Deks Olje D1

D1 Marine OilDeks Olje D1 is a highly saturating wood oil that 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.

Deks Olje D1 is a clear oil that gives a clear matt finish enhancing the natural beauty of the wood and it is easy to maintain with no sanding or stripping required.

As with our previous products, Deks Olje D1 does not form a film on the surface of the wood but instead protects it from within. This means it will not peel or crack.

  1. I am a member of a garden group We have 64 raised beds growing vegetables using scaffolding boards, they need replacing due to rot. Can you recommend any of your product that is safe to use and will not contaminate the soil in the raised bed or surrounding soil.

    1. Hi there John,

      Just a coupe of things to check before answering:

      – What wood are the beds made from?
      – How old is the wood?
      – Has the wood been previously treated?

      All the best,

  2. Thank you for your reply,
    We have 64 raised beds growing vegetables. We are looking for something that we can treat the wood that will not contaminate the soil.

    At the moment we are using scaffolding planks made from southern pine. About 75% of the planks will need replacing, either with Scaffolding plank or white deal planks does your product work with non treated wood or could we use your product on pressure treaded white deal wood to seal it from the damp soil


    1. Hi again John,

      For application on to new wood you would first need to prepare them with the use of Seasonite: https://www.owatrol.ie/product/seasonite/ initially and the after 9 months clean and finish them. Which finish you then use is really a preference of colour etc.
      Alternatively, you can remove mill glaze using Prepdeck:https://www.owatrol.ie/product/prepdeck/ / Aquanett: https://www.owatrol.ie/product/aquanett/ & Net-trol: https://www.owatrol.ie/product/net-trol/

      You could use H4 Wood & Stone: https://www.owatrol.ie/product/h4-wood/ if you want to protect without changing the colour, or equally Aquadecks: https://www.owatrol.ie/product/aquadecks/

      Understandably, you would just need to be careful when applying any finish but they shouldn’t have any issues with the soil.

      I hope this was helpful.
