How to treat Pine battens for external use?

RonaldAce

Hello Bunnings workshop.

I recently bought these pine battens to make an outdoor screen, thinking that I could easily apply some stain or varnish to protect & make them weatherproof. However I now realise that this may not be possible as they haven't been properly permeated like treated pine.

As a pre-coat I used Feast Watson timber primer . (saw on a previous thread here).

I was wondering if you could recommend a topcoat that will help with weatherproofing. But also not make it yellow like oil does.
Or is there a white wash I could use for this? ( I still want to keep some timber grain)
From what I have read, some/most Polyurethane clear coating also turns pine yellow?

I understand this is not the best timber for outdoor use and I should have done some homework before purchasing. But I don't want all this timber to go to waste.

Any advice would be greatly appreciated.
Thanks in advance.

Hi @RonaldAce,

I'd recommend going for Intergrain Ultraclear as it doesn't have the same honey-coloured hue as an oil-based product. However, yellowing over time was really an issue many years ago when oil-based polys would yellow extensively, but that's not so much of an issue now. Regardless, the Ultraclear water-based would be the clearest coating to apply over the Feast Watson 1L Timber Primer and won't yellow over time. Just make sure to coat all surfaces of the timber to ensure water can't enter their surface.

I'm not aware of any whitewashing products that would provide protection from the weather.

Please let me know if you have any questions.
