Re: Oiling a new merbau deck

Hi there, information looks handy, does this also include the pre oiled merbau?

I am gettya delivery Sun for an installation around pool next week.

Trying to avoid tannin bleeding into pool.

Regards

Re: Oiling a new merbau deck

Welcome to the Bunnings Workshop community @Jaylintara. It's fantastic to have you join us, and many thanks for your question about pre-oiled Merbau.

 

Our pre-oil Merbau comes with a priming coat of oil designed to protect the product until it is top-coated with your preferred product. You can read more about the coating in the product brochure. You will still need to let it naturally age or use a product like Intergrain 1L UltraPrep Timber Cleaner to strip its tannins before coating.

 

I suspect that you'll still see a significant amount of bleed from this tannin-rich timber as no ageing process has been done to it. This might be slower than a non-primed timber, but I believe it will still be evident.

 

Please let me know if you have any questions.

Re: Oiling a new merbau deck

Thanks Mitchell.

I'm happy to use the cleaner to speed up the process of tannin removal on surface. I'm more concerned with leaching from the last few rows and facia boards that hang over pool edge, will these turn my pool tea colour and stain my liner? Or will it not be noticeable in 55kl of water bring filtered?

Should I leave the last few rows off to avoid any tannin in pool?

@Jaylintara,

 

I'd suggest you treat and clean those boards prior to installation. I suspect the tannin leech will be diluted by the volume of water. However, I am concerned about the staining of your liner. Staining of liners seems to be a fairly common issue with installing Merbau up to or over a pool.

Re: Oiling a new merbau deck

Thanks again Mitchell.

I think I'll leave facia boards off until washed a few times with Tannin cleaner, I'm also going to staple builders plastic on underside of deck structure to create flashing between deck and pool coping, this should mitigate leaching into pool.

Re: Oiling a new merbau deck

That sounds like a very sensible plan, @Jaylintara.

 

Please keep us updated on your project, as it sounds like it will be a sensational build. We'd encourage you to start a discussion so our other members can follow along too.

 

Reach out if you need further assistance. We're here to help.
