Even with the choice of wood one can argue: untreated pine, moreover, in a thickness of only 18mm (standard) shows no means "extremely weather-resistant." Better a resin richer wood such as larch would have been.
I strongly recommend to impregnate the components prior to assembly or oiled, depending on what is a rather. But you should remember that the sandbox is constantly exposed to the elements, therefore prefer even get involved too much than once too little. Here it does every regular Imprägniergrund (possibly in combination with a maintenance oil).
What is still noticeable negative the lack of ground.
Here Abbhilfe must be created in the form of a film (if the sandbox is not moved), or better yet by preparing a bottom (tip: Impregnated "3-layer panel" cut to size, including 2-3 strips of oak with the underside fortified barrier cardboard (bitumen sheet, besanded), the plate comes out of the water. When sealing the sandpit down (base plate), one should remember that the cover is not waterproof, the rainwater so shall have the opportunity to run. From tarpaulins I advise because this water (in the form of condensation water on hot summer days after rain) "hold", which leads to decomposition of the wood.
The assembly is simple, everyone was supposed to get. I have replaced with stainless steel screws by the manufacturer of my confidence the supplied screws.
Conclusion: Expandable and post-treatment of vulnerable sandpit for the small - medium purse. Still better than plastic; therefore: 4 stars and Recommendation.
