Caulking for teak

[Bogan 8]

What's the best stuff for caulking between teak planks in a cabin side?

 

My father has an old bridge deck launch with varnished teak cabin sides and has tracked down a significant leak to the seam between to wide planks of teak. The seam has been previously filled with some sort of sealant, probably a silicone one.

 

Cheers

there are two options, that are really four

 

- terason lm280 from atl

 

Or there are three choices with sika. 290dc ( quite thin viscosity ), 295 dc ( mid range viscosity and good uv ) and 552 ( good all round )

 

You will need to sand the area clean, then acetone wash it, then 205 cleaner, and timber primer. it makes a huge difference to the life and sealing/bonding of the deck caulking. prep is every thing with it.

If the plank edges are straight you might be better off splining the seam, especially if it is old, stable teak. It'll look much better varnished than a caulked seam and be less prone to the movement which would crack the varnish. Unless the seam is very open a spline 4-5mm wide and 1/3 - 1/2 the depth of the seam should do. If appearance is also important inside, you may want to spline that side also.

if it's had silicone anywhere near it this is probably the best plan of attack
