On the data sheet on Sikaflex's website
https://usa.sika.com/content/dam/dms...flex291-us.pdf they have a cure rate chart. For a 5mm thickness bond. They say it will take two days to cure at approx 75 degrees/ 50% RH, but in the next column on the same datasheets it says to not totally immerse in
water for one week. I was under the impression from some online comments you can go back in the
water quickly. Maybe I misunderstood and should have done a bit more
research so little confused with that...
I just installed two thru hulls with it today and will do the third tomorrow morning. I estimate that the maximum thickness of Sikaflex for my application could be around 5mm in some places. I beveled the opening of the hole in the
hull at 45 degrees to create a thick o-ring seal between the fitting and
hull. Thickness between the side walls of the fitting and the hull are maybe 2-3mm thick. The thru hulls do sit flush against the hull though so less than 1mm thickness there. Im using it
California and its been pretty much 75degrees and 50%+ RH here all week.
So do i have to wait a week to let it cure before going back in the water or two days, according to the cure chart? Hoping someone who really knows this stuff can clarify this for me...
Thanks
