What type of sealer should I use?

[ianqv]

Dear Members of the Parish

I wonder if someone out there could advise....

I wish to pick out and refresh the sealer between my keel and the fiberglass hull.
Would anyone know if there is a particular type of sealer that I should use?
I've looked around the local chandlers... but can't find anything.

As always.... many thanks

Ian

Hi Ian

I have always liked Sikaflex 292 for underwater jobs - it is very sticky so should adhere well.

Right on Malcolm .

Ian , I have used the same sealer (sikaflex) on my keel/hull joint ,.........3 years ago , still going strong.
Before that I have tried Tec7 , no good , it came off after one season.
Nevertheless Tec7 is ok ,from my own experience anyway , but it needs to be sandwiched.

I confirm Malcolm´s and Sailblue´s choice: sikaflex 292.

However, for optimal adhesion, do "invest" in a bottle of Sika-primer, whatever you sikaflex. It comes in a aluminium bottle.

It is a siruppy, virtually clear, but not cheap liquid that you apply on the prepared (degreased and cleaned) surface with a brush. Leave to dry for minimal 30 minutes and then apply your sikaflex.
