Wood

Which wood does FATMOOSE use?

Impregnated FATMOOSE wood made of pine or spruce is naturally and sustainably cultivated and is known for particular outdoor durability. It provides our products with a firm footing that ensures both fun and safety.

Is it normal that there are cracks, knotholes and green stains in the wood?

Wood is a natural product and no two trees are the same. Small cracks or knotholes are therefore perfectly normal. According to DIN standard 4074, the statics of the wood are not affected by cracks under a quarter of the length or thickness of the beam. On the contrary, they actually show that the wood is still working!

Why does the wood's volume change so frequently?

A little
In particularly moist or dry storage, it may happen that the wood expands or contracts somewhat. Not only is this harmless, it's actually good for the wood, as it helps it best withstand the weather and environmental factors.

My climbing frame has green/white patches on it. Is it mould?

If your FATMOOSE product has small white or green stains, there's no need to worry: It can happen that salts from the wood and the impregnation gather and escape onto the surface. You can confidently ignore these patches. If they still bother you, you can simply sand down the affected areas.

What does it mean when wood is impregnated or pressure treated?

Our wood is known for providing several years of playtime fun, and to guarantee that, we have to make the wood durable. That's why we impregnate it using pressure treatment. In doing so, preservatives are pushed into the wood at high pressure. This means that the wood is then protected against insects, fungus, rot and long-term contact with soil and water.

My wood is damp, is that normal?

In general, moisture is not a cause for concern: In our experience, it can take some time for the moisture that results from the impregnation process to totally disappear from the wood. 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.

Should a climbing frame be glazed and which wood glaze is the best?

You don't need to glaze or varnish our wood. The water-tight pressure treatment provides the best protection against the elements. If you really want to play it safe, you can of course treat the wood again with a special glaze certified according to DIN EN 71 Part 3. These glazes are safe for children and the environment.

Can the wood be painted or varnished?

If you want to freshen up or change your climbing frame a bit, go right ahead! To ensure your warranty is unaffected, you should however note the following when doing so: To maintain wood quality and lifespan, only use microporous varnishes and long-lasting paints that have been certified in accordance with DIN EN 71 Part 3. These paints will not harm your child and have been tested to ensure they are safe for children.
Tip: Sand the wood using sandpaper before painting. Not only does paint take better on a rough surface, but you'll also remove impurities on the top layer of wood at the same time.

What can I do about the green patches?

Due to the impregnation of our wood using pressure treatment and the fact that the wood is continuously working, it can happen that small patches of salt appear. You can easily sand them away or just leave them be if they don't bother you.

How do I counteract the swelling and shrinkage behaviour of the wooden play equipment?

If the wood gets damp or is stored for a long time, it can happen that its volume changes slightly. In order to avoid this, you should store it in a dry place and not for too long. After all, you don't want to keep your kids waiting for their brand new FATMOOSE playground equipment, do you?
