Best Options For Shed Treatment…

Garden Shed Treatments

When you have built your garden shed, it is essential to maintain it in a right way. When maintained and treated correctly, you can enjoy your garden shed for so many years.

It is highly recommended that you treat your garden shed within two weeks of assembly. It is possible to treat the shed panels prior to installation if you wish, this may be the best option if access to the exterior of the shed will be difficult once built.  If treating your garden shed, keep in mind that the colour of the preservative might appear slightly different because of the qualities of the wood. When selecting your treatment make sure that it is ideal for use on exterior timber.

When using treatments to garden sheds, it is essential that you must stipple it into the edges and gaps as this will assist in preventing water from seeping in.

Wood is an organic product and thus will alter with differences of humidity and temperature. If the weather becomes very dry, small cracks might appear in the wood grain. The cracks will usually disappear when the weather normalizes. The small cracks which are developed after a drought is unavoidable, but they don’t affect the load bearing capability of the garden shed.

Garden sheds are typically supplied as either untreated, dip treated or pressure treated, and a few manufacturers will paint the shed before delivery.


If you choose to purchase an untreated shed, then you will obviously be responsible for applying some kind of preservative.  No treatment at all can be the cheapest method of purchasing a shed, but bear in mind the cost of purchasing the preservative yourself and of course the cost of employing someone to apply.

You can opt to leave the shed untreated, but it will almost certainly suffer from rot and start decaying within a few months.

Dip Treatment

The majority of garden sheds on the market today have undergone a dipped treatment. This efficient kind of treatment, usually has an orange/red finish. It is also considered the cheapest and quickest way for manufacturers to treat their products.  Once completed each panel is submerged into a large vat of the chemical preservative for a few seconds. It is then removed from the vat and allowed to dry.

It is recommended that a dipped treated shed should receive a further coat of treatment once installed.

Pressure Treatment

Pressure treatment uses a chemical preservative that is forced deeper into the grain of the timber under the pressure of the vacuum.  Each length of timber undergoes the procedure before being made into shed panels. This method is widely recognised as the most reliable way of preserving timber. Anti-rot guarantees with pressure treated garden sheds could be more than 15 years.
Aside from, longevity, the most significant advantage of this kind of treatment is that you never have to use another preservative all through its lifetime. However, it is advised that a waterproof coating be applied to the shed, as the timber is not impervious to water.

Tanalised timber is the same as pressure treated timber. Once treated the wood is usually coloured green. This colour does fade over time and with a little sunlight. If you would prefer a different coloured preservative or to paint it, make sure that the shed panels are dry and clear of dirt before doing so.

Pressure treated sheds are the most expensive sheds due to the cost of the tantalising process. However, with no further treatment required and a guarantee of up to 15 years, it may well be worth the money.
