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

Impregnation Impregnation
  • Water is pressed into the wood through pressure impregnation
  • Due to the impregnation, painting is not necessary

The impregnation may cause the wood to be damp. It is therefore advisable to unpack it after arrival and let it dry for at least two days.
Pre-drill the holes before inserting the screws. This minimises the risk of damaging the alloy of the screws.

Salt efflorescence Salt efflorescence
  • Superficial white to greenish spots
  • Mixture of existing resin and ingredients of boiler pressure impregnation
  • Fades over time due to the weather

Strongly affected areas can be easily sanded!

White spots White spots
  • During storage, superficial stains and mold may develop
  • Not a health risk
  • Fades over time due to the weather

Easy removal by wiping with a cloth!

Cracks and branches Cracks and branches
  • Branches, grains and pith are part of the characteristics of the wood
  • Dry cracking is permitted according to DIN 4074

Cracks with ¼ of the length and ¼ of the width are statistically harmless!

Swelling and shrinking 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

Unpack your wood immediately and let it dry for at least 2 days before assembly!
