Benefits of a dip-treated shed or workshop

What is dip treatment? 

  Dip treatment tank  

Dip treatment is the most common method of applying preservative to timber in bulk.

With this technique, all the wooden components that will make up the shed are dipped into a tank of either water-based or solvent-based preservative before the panels are put together. 


What are the advantages?



Dip treating achieves a similar result to brushing or spraying the preservative on to the shed, but is carried out in advance at the factory – saving buyers time and effort.

The dip-treating process is quicker, simpler and less expensive to carry out than pressure-treating (also known as tanalising). Labour and storage costs are lower, making this type of shed popular and affordable.



Dip-treated sheds typically come in a rich reddish gold colour. This is because the timber derives mostly from British redwoods, which can vary in tone. A cedar-red dye is therefore applied during manufacture to ensure that every plank of wood takes on the same colour. This will gradually fade until the timber is re-treated.

Wide choice

Because dip-treated timber is used to make the majority of sheds and workshops in the UK, there is a huge range of different shapes, sizes and specifications for buyers to choose from. We stock a wide variety of dip-treated sheds with both apex and pent roof styles, ranging from a 3X5 sentry type model up to a roomy 8X12 workshop with double doors.


Environmentally friendly

Forest Garden sheds are coated in water-based preservative, which is kinder to the environment than solvent-based treatments, is not flammable and has little or no smell.

Sheds that have been dip-treated are guaranteed against rot for 10 years, provided that they are re-coated annually with a suitable wood preservative. Re-treating your shed every year is essential to keep rot at bay, as well as to prevent the wood from drying out and warping.
