What oil for sandpit using sienna micropro sleepers?

[matt901]

Hello, i've made a sandpit out of Sienna micropro sleepers. Online it says to use CN timber oil to seal it. Is that safe for use in a sandpit? What other options would you recommend?

Hi @matt901,

Welcome to the Bunnings Workshop community, it is wonderful to have you with us.

If the sleepers haven't been cut, then there is no need for any additional products, as they are pressure-treated so that the treatment penetrates to the inside of the timber. 

If there are cut ends, then this Ecoseal Tanalised Timber Treatment is a copper-based treatment that can be applied to the cut ends of the timber to add additional protection. It is, however, green-tinted and can alter the look of the timber slightly.

If the sleepers are entirely above ground, there is also this Tanalised Clear Enseal Timber Treatment, which can be used to seal the cut ends of the timber.

Let me know if you have any further questions.

Hi Jacob, thanks for the tips!

This is the sandpit I've assembled. Most of the cuts have another sleeper already on the end of it so aren't too exposed. How do you treat these ends?

 

Are there any non toxic and clear sealing solutions? I'm just a little worried of it leaching into the sandpit and garden as the ingredients of the ones you suggested look pretty toxic. 

Thanks!

Hello @matt901 

I suggest looking at linseed oil, tung oil and danish oil. These options are safe for use around plants, animals, and children since they don't contain harsh chemicals. Please remember to follow application instructions and that the oil must be fully dry before using the sand pit. Please keep in mind that some danish oils have additives so make sure your getting danish oil that is safe.

If you need further assistance, please let us know.
