Hi I've currently purchased some pine planter pots made from old pallets. They will be used under an alfresco but as they are on the edges of the paving they will still be exposed to natural elements, eg rain, sun and retic. I'm wanting to seal the timber with a natural finish as I like that rustic raw timber look but have no idea what product to use. I'm unsure if linseed oil or decking oil is best. I am considering to put some sort of garden plastic inside to help reduce rot and decay and I will also be drilling a draining hole as there are none at the moment. Also putting the pots on small wheels so they will be off the ground and easier to move. I'm unsure if the pallets used are treated or not. Any advice would be awesome!! 😄
Hello @emmz
Yes, you can use Linseed Timber Oil on the exterior of the wood. However, I still recommend using the bitumen sealer for the inside of the tub as it will be in contact with the soil.
If you need further assistance, please let us know.

this was the product I was referring too as my local bunnings never has pure linseed oil in stock... But yes I am using the bitumen sealer on the inside 😊
Hi @emmz,
As mentioned before, I recommend you use a hard coating and not an oil. Untreated pine is not suitable for exterior use, so your planters should really only be used in aa area protected from rain or indoors. Pine will begin to decay as soon as water enters it, and a hard coating will prevent that from happening. With an oil, you'd need to fully saturate the timber fibres to prevent moisture from entering. If you are slightly delayed in your yearly application of oil, the timber will begin to decay. If this was a treated pine planter, you be fine to use the oil, but as the timber is not treated you must prevent water ingress at all costs.
