Teak decking - new - treat it or do nothing?

I have just finished renewing the teak in the cockpit of my Vancouver 28 - big job, but results really good. The question arises as to whether or not I should treat the brand-new teak 'decking'. A cleaner is obviously not required; maybe an oil to increase waterproofing? Anyone have any advice/experience? What treatment would be best and why? Regards. Jim Izzard.
 
Simply coat it several times a year with a flood coat of Boracol 5RH. It will stay cleaner and won't require any other attention apart from periodic washing with a sponge. Hallberg-Rassy recommend using Boracol on their teak. Some people will suggest using Patio Magic, which will do a similar job; it's cheaper, but Boracol is better, and it's what I'd use on new teak.
 
If you had the time or suitable crew you could treat with Semco - we use on just our rails and capping so less wear perhaps than cockpit sole but you will see some photos on this forum of results when used by Mobo on decks I believe .

What PVB said!
 
Semco seals the deck from water penetration, which reduces the effect of frost eventually causing the surface grain to splinter and break away, but more than three coats and it needs cleaning off with Wessex two pack.

My deck had spent its life in frost free Jersey, which meant once I cleaned it it came up like new, but I do prefer to keep it sealed even for the work this generates and I personally would use it on a brand new teak deck. It also locks in the golden colour, although I know some do prefer the silvered look.

Boracol or Patio Magic is still required to keep the algae at bay.
 
I know of one owner who oils his teak decks annually: after 30 odd years they are in remarkably good condition for their age but very dark. Personally I prefer Patio Magic or Boracol twice a year, then just gentle washing regularly. Semco and similar sealers can look very good, and probably protect the expensive wood, but need regular re-application.

Patio Magic (from Brintons) is NOT the right stuff. It is not for wood - read the label. The correct stuff for wood is Brintons Moss and Mould Cleaner (MMC) professional. It is designed for wood as well as stone.

There'll be a lot of people on here who'll disagree with you! :rolleyes:
 
Patio Magic works fine. I suspect that Boracol might last a bit longer, but the difference is not great and Boracol is quite a lot more expensive.

Modern teak is mostly plantation grown and quite soft - damned environmentalists stopping us raping the rain forests! A couple of coats of Semco seems to help seal the grain and reduce the rate of wear and tear.

Having just bought a can for my patio, the label does not have that list, it excludes wood, where as the bottle of MMC Pro does.

Anyway - I called them and they say they are both OK on wood, just that MMC is stronger.

So I bloody well wrong - again....... :disgust:

Boracol or Polycell 3in1 mould killer from B&Q. Easier to get hold of than Boracol and seems to work just as well. I do it twice a year.

Polycell 3-in-1 Mould Killer used to contain the two active ingredients found in Boracol - benzalkonium chloride and disodium octaborate. However, it was reformulated about 10 years ago, since when it has no disodium octaborate in it, only benzalkonium chloride. So Boracol is still the product of choice.
 
Patio Magic. Once a year mix 4:1 water to Magic.

Patio Magic ...

Does it work - for me Yes

Is it cheap and easy - for me Yes

Does it also work on GRP, Fenders, Ropes, Awnings & Covers - for me Yes

Do I get a session on the patio at home from the same container - No

I get two sessions after the boat has been thoroughly sprayed.

That is until the EU ban it.

maybe, but I have used it for the last 13 years or so with good effect. A couple of years ago I bought boracol which works just as well but is not so nice to use as its stickier. I didn't notice any improved performance from the boracol, both stop the teak going green, kill mould which is then washed off by rain and sea so no further deck treatment is needed. The important thing to avoid is scrubbing it.
 
I bought some Iron Sulphate that I have used at home on some moss on my driveway. It is a powder that I mixed with warm water in a garden sprayer . Relatively cheap.
Unfortunately there has been rain shortly after two applications which must have reduced its effectiveness . However the moss is gradually looking black rather than its previous bright green.
Not sure I dare try it on the boat.
