teak deck reviver - silicone oil
« on: November 09 2024, 08:21 »
I have been investigating using silcone oil as a teak deck reviver.
It brings back the colour
It stops water penetration
It is does not evaporate.
It can be controlled "dosed" by using dilution with volatile solvents.
It penetrates the surface.

The only drawback appears to be that that prevents any further application of other products - nothing will stick to it.

Does any one have experience or thoughts on this idea.

Hi all,
I also don’t see the need to put other treatments on a teak deck than water and soda or detergent.. teak in itself is non-skid and putting all kinds of oil on it is only cosmetic but does more harm than good to my opinion.
Don’t use HP washers or hard brushes to damage the surface, gentle brushing in small circles and if heavy green sweet scotch brite will keep your deck amazing. On our previous Bavaria 300, the new laid teak deck still was very good after 20 years in use…
It is the downside of teakdecks (besides the high price and sustainability issues nowadays) is they require a lot of TLC… so that’s why we also don’t have teak anymore on our Bav41…

Sing shanties while cleaning, really helps!

Thanks Happy sailor

By soda do you mean Sodium carbonate (aka washing soda).
I have used oxalic acid to good effect. I am not sure that is all that good for the teak. Anyone have ideas.

The teak is only 3-4mm thick. Not what you would call a traditional teak deck.

Yes, I used cleaning soda. Off course a good rinse afterwards worked very well and protected the deck against green for a season.
I had the original Bavaria plywood/ teak laminate deck replaced with 6 mm teak and it lasted very well..

The very best treatment for teak decks is to flood coat it with Boracol 5RH, using a soft paintbrush.  This is an algaecide and a fungicide, widely used for wood preservation.  A lot of the "dirt" seen on teak decks is in fact mould, and the fungicidal properties of Boracol kill that off, leaving the deck looking clean without any scrubbing.  I used it for years on my Hallberg-Rassy, and it's also great for sprayhoods, etc.

Yes, nothing will stick to it...

Be sure what you are using as there are a range of types of silicone oils, mostly based on PolyDiMethyl Siloxane (PDMS).  Some used to treat fabrics have reactive chemistry added and are able to bond onto cellulose like cotton or wood.  Others are simple, unreactive oils which remain oily and mobile.  Unreacted oils will creep over time, from weeks to years onto areas where they aren’t wanted and can attract dirt and prevent paint or sealant adhering.
There aren’t many solvents that dissolve silicones well.  Paraffin is the most accessible one that works, or it can be thinned by emulsifying with water and a generous dose of Fairy liquid or similar.

Personally, I wouldn’t use boracol on the wood despite it being effective.  Such borates have been phased out of many consumer products because of the repo toxin risks.

I kept our cockpit teak looking good for a few years with sanding :o and oil.  Now we accept the inevitable and have let it silver.  Leaving it with a splash of patio magic in the spring shifts the winter algae and grime.  Salt water and rain take over the maintenance for us after that.

Boracol is indeed effective, but has minimal toxin risks - the amount used isn't huge, and once it's dried you're not likely to be unduly exposed to any toxins.  I used Boracol for years, and still use it today on my sprayhood (I now have a fake teak deck).  I started using it because it was recommended by Hallberg-Rassy, whose advice is generally respected.
