Which SABA product ?
Which Construction sealant ?
How would the above react to an oily wood eg Teak ?
The SABA Product is SABA Seal One Fast. In UK you can get 600ml sausage for around £20.00. You also need to buy the bigger sausage gun.
The cheaper option is Tradeseal MS/HS available from www.thegluepeople.co.uk
at £7.20 per 290ml tube. As far as I can see, this has exactly the same properties as Seal One Fast.
Certainly SABA is good for teak (as I have not tried the Tradeseal I could not comment except to say that I would be surprised if it was incompatible). There is also the question of whether to de-grease and prime. It is generally assumed necessary with 'new' teak and not on 'old' teak. As mine was 'oldish' I compromised and just used the SABA primer. Time will tell if I have made a mistake!
My main problem was, although the boat cost around £400,000 to build (46 ft steel cutter ketch) and was built by a highly regarded organisation, the deck was a bit of a bodge. Planking was plain (or flat) sawn, not quarter sawn which meant the erosion had left huge undulations. Fortunately the depth of timber was such that I could plane and sand it evenly. In addition I discovered that only one in five of the eroded teak plugs I removed actually had a screw underneath it! Fortunately the deck was thoroughly sealed to a ply sub-deck so it was no great structural problem but certainly highlighted the fact that you cannot always believe what you see.
My other boat is a 1963 Hong Kong built all teak Cheoy Lee Vertue - now, with her, there are NO shortcuts!
Hope this helps.
