Timber information
What are typical wood characteristics?
Wood is a natural and sustainable raw material. During the growth process each tree develops it’s own characteristic features. Typical wood features such as branches and grains make each piece of wood a genuine one of a kind. The distinctive natural features are deliberately accepted and do not constitute a defect.
Should I paint the wood?
No, you do not need to paint the wood. The wood used in our climbing frames is impregnated and therefore weatherproof.
Why high-pressure treated wood for climbing frames?
Wickey deliberately choses pressure-treated wood because of the many advantages compared to natural wood. The child- and environmentally friendly pressure-treated wood is also used in professional, public areas.
- No tedious sanding and annual painting
- Increases the life of the wood
- Protects against weathering, rot, mildew and fungi
- No expensive coating colour needed
- Saves time, effort and money

Salt efflorescence
- Superficial white to greenish spots
- Mixture of existing resin and ingredients of boiler pressure impregnation
- Fades over time due to the weather
Tip: Strongly affected areas can be easily sanded!

White spots
- During storage, superficial stains and mold may develop
- Not a health risk
- Fades over time due to the weather
Tip: Easy removal by wiping with a cloth!

Cracks and branches
- Branches, grains and pith are part of the characteristics of the wood
- Dry cracking is permitted according to DIN 4074
Tip: Cracks with ¼ of the length and ¼ of the width are statistically harmless!

Swelling and shrinking
- Volume change due to moisture absorption/drying is typical of the wood
- To ensure accurate assembly, not all wooden parts are pre-drilled due to wood movement
Tip: Unpack your wood immediately and let it dry for at least 2 days before assembly!

Impregnation
- Environment and child-friendly high-pressure impregnated wood (Tanalith E 3475)
- The impregnation solution is forced deep into the wood with water
Tip: Due to the impregnation, painting is not necessary!
