The fee for that service was based on a standard 15% of the cost to the teak, this in effect was offset by the use of our very fine cutting saw blades, many rip teak to size with a 4mm blade, the cost in sawdust needs to be seen after a few hours ripping a teak decks slats. It was not long before teak deck slat buyers were asking what black inlay caulk to use, we became stockists of Dow-Cornings 797 and sold 1000s of tubes over the years.
The black caulk is Dow-Corning 797, this I have used myself for decades and never had a bad tube, its weather and UV proof, will take heat to plus 150c and cold to minus 50c, its stable and needs no primer.
We can also do colours such as stone, white, grey etc, due to the fact that it has a 12month shelf life we will only buy in to your order and on a minimum of 12 x 310mm tubes, which is one carton, It is highly cost effective and works. We can also recomend it for sticking in glass or Lexan type windows on cabin side, no primers or fastners will be required .
Note, Dow-Corning now brand the 797 grade as 813, tests have been done at the factory for a local superyacht builder where a white deck caulk was required, the tests prooved that the product is suitable for this use.
