At Jungle Gym, we take pride in using high-quality, natural wood for our playground equipment. However, because wood is a natural material, it may show certain characteristics that are completely normal. These do not impact the safety, strength, or durability of your play equipment. Here’s what you might notice:
Cracks
Wood naturally expands and contracts with changes in temperature and humidity, which may cause cracks.
Cracks smaller than ¼ of the wood’s length or cross-section will not affect the strength or stability of your playground equipment.
Rough Surfaces & Splinters
Despite our careful selection, some parts may have rough spots or splinters, especially around knots or edges.
These are purely aesthetic and can be smoothed out with light sanding if needed.
Knots
Knots are natural parts of the wood where branches once grew. They add character to the wood and do not weaken it.
Small Holes (Insect Exit Holes)
Occasionally, you might see tiny holes where insects exited the wood. This is normal and occurs after the wood is cut, as it loses its nutritional value.
These holes do not affect the strength or quality of the wood.
Sticky Spots (Resin Pockets)
Coniferous trees like pine and spruce produce resin naturally. It may seep out, especially in warm weather.
To remove resin, try scraping it off with a brush or soft tool. You can also use a mild heat source or a resin removal agent. Be careful not to damage the wood’s finish.
Black Spots (Black Fungi)
Black spots can appear if the wood is exposed to moisture, leading to surface mould. This is usually not harmful if addressed promptly.
Keep your playground equipment clean and dry to prevent mould. If it appears, clean with warm soapy water or an anti-mold cleaner. Follow up with a waterproof sealant to protect the wood.
Discolorations (Douglas Wood & Hardware)
Douglas wood can darken where it contacts metal hardware, especially in moist conditions.
These stains are only superficial and can be lightly sanded away if desired.
Tips for Maintenance
Regularly clean your climbing frame to keep it in top condition.
Apply a clear, waterproof sealant to protect against moisture and mould.
If you notice any rough spots, light sanding can help keep surfaces smooth and splinter-free.
By understanding these natural characteristics, you can enjoy your playground equipment for years to come, knowing it’s built to last!
