YM Senior - Painting around steel keels
Posted: Tue April 20th, 2021, 2:54 pm
Hi All,
So I am in the process of painting the hull and applying copper coat to it.
I have already sanded down to bare wood and was very happy to see that apart from some small areas that seemed to already have been treated before, there was no visible signs of rot damage.
I have not taped over the seams but I did apply a coat of epoxy to the bottom of the boat straight to the wood. After this I applied my first coat of Hempels light primer (2 part paint). I am looking at applying one or two more coats.
For the steel keels I stripped and sanded with an angle grinder and after that cleaned with white spirit and painted with rustins rust converter. Afterwards a coat of Hempels light primer. will apply more along with the hull.
My concern now is how to treat the junction between the keels and the hull. At the moment it seems to have a flexible caulking of some kind. It does not crumble if I scratch it with a blade and it is still elastic, but I am unsure if I should paint with epoxy on top of it.
I have some Sikaflex Black 291i and I am tempted to try and push the existing unknown caulking in and applying Sikaflex all around the keels to know I have a sound seal that I can then paint on top.
But I am unsure if it makes any sense to paint on top of this connection. Will there be much movement in such a small boat/ small keels?
Previously it was painted over.
Please see image attached (mind that the epoxy is wet and it makes all look quite dark and bad...), the junction is above the steel plate that takes the bolts and the plywood board that sits against the hull, about 2mm high.
Any thoughts? Thanks!
