Sikaflex removal

Does any one know the best way the remove sikaflex 291 from the transom.

Had to remove my launch wheels to do some work and want to put them back on with fresh sealant but have a load of the old stuff to remove first.

Can anyone help

Jake

Funnily enough I'm just swapping transom wheels on my one week old SIB and cursing that I used Sikaflex as it's bond was strong enough to pull off the transom paint under all the fittings where I used it.

A couple of places I found I could rub it off with fingers but where it had a good bond a scraper was needed and this is where it pulled the paint up too.

The makers tech sheet says it all... "Once cured, the material can only be removed
mechanically.".

Or with really cheap baby wipes, the cheaper and the less likely to go near a baby the better!

One wonders what you were doing with a baby wipe to your boat to have found that one out

Never tried it, but would a bit of heat from a hairdrier or heat gun work. It helps when using a scraper on many other glues and sealants I know of.

I can confirm that baby wipes are one of the few things I've found that can remove Sikaflex from skin.

When you have young kids there is never a pack of Baby wipes too far away, and you do discover how useful they are, so much so that even though the kids grow up there is always still a use for the baby wipes.

Little off topic but not that sure we will have this problem in the future. I have recently used
the new eco SIKA 291 I cure and its sticky yes, but i don't think it is even close to as strong bonding as the old one? is it only me or anyone else noted the same?

You could always try the Purflex equivalent if Sika has gone downhill.

Once the worst has been scraped off I find acetone helps to get rid of the remnants

Scraper, baby wipes and if needed, acetone it is then.
