Sikaflex removal

[glenn2926]

Afternoon, does anyone know of an easier way to clean off sikaflex than elbow grease?

No... ive never found anything that will remove it once set other than mechanical..

From Sika >>

In terms of removing cured Sikaflex®, this depends entirely on where it is applied. However generally speaking, cured Sikaflex® can only be removed mechanically ie a sharp knife, vibra-saw, cheese wire – or abrading it off with a sander.

Thanks Andy, that’s what I thought. Looks like I’m back to rubbing. The thing that seems to work best is just rubbing it with my finger. The skin is getting a bit thin now.

Silicon remover will soften it, then use a blunt chisel.

Ive had the stuff covered with that diesel , white spirits , cellulose thiners
And other solvents for days.. made next to no difference... and then theres the worry about the solvent might do to the structure

I found brush silicon remover on it just leave a few mins and the Sika comes off a lot easier, then wiped with meths to clean the solvent off, no damage to GRP. Also found a bit of silicon remove on the cheese wire when cutting the fixing off helped.

I usually use a sharp chisel, with great care, and then rub off the thin film left. A blade wider than the silicone strip reversed is usually best. A sharp blade cuts the stuff off.

I use one of my wife's wooden washing line pegs .works a treat lol.

Well that was fun. Anyway the afternoon was not wasted. I used the plastic applicator that comes with car body filler to scrape off the sikaflex. This worked very well as the plastic does not damage the paint work. It was a little time consuming to say the least but all is good now.
I do have another window to remove and reseal and will take extra care when refitting with cleaning off the excess sikaflex before it cures.
Thanks for all the ideas from you all.

I dont normally use pu adhesive to install windows skylights etc..
As long as your surfaces are cleaned and sound a non setting mastic is the normal stuff to use..
Something like this if the link works..
