Hi,

Which of the Sikaflex products would be best for repairing a seaping hairline failure of keel sealant until we can re bed completely. The idea is to simply scrape out the material around the failed sealant, dry and replace-although stating the obvious, the sealant is on the outside of the boat and underwater.

Cheers,

Tony
 
Saba 750 xl from marineware.com in southampton, its a structural adhesive / sealant or you could use marineflex from marinemastics.com in waterlooville as temporary fix then use their marine seall 033 product which i know alot of people here rate.

I forgot to mention i attached my Centaurs keels with the former, no primer or special cleaners required just a wipe with acetone. Couldn't stomach the limb money wanted by Sikaflex for the special little bottles of cleaner and primer at £40 a pop then 4 or 5 tubes at £30 a pop for sika 292.

Had the keels attached and swinging free courtesy of a box cradle i made for my boat with a couple of simple jigs to measure lateral movement and in the three months the boat sat there no movement whatsoever so a big rog super thumbs up for saba sealants.

Tec7 is the sealant you want http://www.tec7.ie/

It's half the price of sickaflex, available in builders merchants around the country, and more importantly, seals perfectly well in wet conditions. Drying out a hull keel joint will be difficult! So tec7 is the answer
 
I had a weep from a rudder post securing stud. With the boat ashore I simply removed the nut and washer and kept dribbling Captain Tolleys leak seal in around the stud over several days until no more would run in. Although it took quite a bit to start with, when the seal was filled the leak stopped and after two seasons hasn't come back.
 
Forget SIkaflex get some CT1 sealant from tools direct .o.uk same price no solvents food quality 1000 times better and I have been testing it for quite a while now and it has not failed even underwater sealing a hole in a yacht under way

+1. CT1 or the cheaper and easier to find alternative polymer sealant/adhesive Tec7. Polymers are versatile and work in the wet, even underwater!

tec7 is the same as CT1, but cheaper, in bigger packs, and available from most good builders merchants.

Swindleries don't stock it in my experience as it's cheaper than sicka, and more effective in all the owner maintenance tasks I can think of.
 
I mostly use the cheaper alternatives to Sikaflex 291, particularly PU40 from Toolstation that appears to be an almost identical product. I have used some of the hybrid polymers like CT1 but find that they do not have the strength of Sikaflex.
