Naturally, you want your summerhouse to last as long as possible in optimal condition. To ensure this, it will have to be protected from the sun, wind and rain. But what’s the best way to do this? If you want to keep your summerhouse in perfect condition, you should treat both the inside and outside. There are two widely used and effective ways to protect your summerhouse from the elements.

Prevent mould and fungi growth


The best protection for your summerhouse is boiler pressure impregnation or spray impregnation. If you opt for spray impregnation, it is important to also stain the exterior of your summerhouse. Both types of treatment ensure that your wooden summerhouse becomes water repellent and is protected from mould.


The difference between boiler pressure impregnation and pretreatment and staining


Pressure treatment
With pressure treatment, the impregnating agent penetrates deep into the wood. But how exactly does this process work? A vacuum is first created in a boiler, after which the boiler is filled with the impregnating agent. Once the boiler is full, pressure is built up in the boiler. This pressure forces the impregnating agent into the wood. This seals the wood, offering optimal protection from the elements.

A downside to boiler pressure impregnation is that the wood may become slightly warped. This can make it more difficult to assembly your summerhouse. On the other hand, your summerhouse will be ideally protected from the sun, wind and rain and will not require future treatments. This is the best possible protection for your summerhouse. The use of boiler pressure impregnation prevents a breakdown of the wood structure.

Pretreatment and staining

Another commonly used treatment for wooden summerhouses is a combination of pretreatment (spray impregnation) and applying a layer of stain to the exterior. The best method is to pretreat all parts of your summerhouse with spray impregnation before assembly. This ensures that all parts are protected that are not accessible after assembly, such as the tongues and grooves of the wall sections. Pretreatment protects your summerhouse from mould.

For additional protection of your summerhouse from the elements, it is advisable to stain the outside after assembly. This will keep your summerhouse protected for around five years, after which you will have to stain it again.

What should you consider when opting for spray impregnation and staining?


There are two very important factors to consider when choosing treatment products for your summerhouse. Firstly, they need to have moisture-regulating properties because wood tends to warp when exposed to the elements. Secondly, the products need to be suitable for outdoor use on wood.

Impregnation is much too much work

You may be under the impression that this is far too much work for you to handle. Some suppliers of summerhouses can take this work off your hands, such as www.lugarde.com .
