Old Sikaflex 295 UV to New 295

[sylibertas]

One of the bridgedeck "windows" of my cat has developed a small leak that is due to the debonding of a short (1/2') section of the seal between the lexan window and the fiberglass frame (probably poor lexan edge prep by the factory). The original seal is Sikaflex 295 UV and I would like to clean up the debonded area, etch the edge of the lexan window (acetone?, the Sika primer is way too messy) in this area, let it dry and then inject fresh Sikaflex 295 UV into the gap. Anybody ever try anything like this? Does Sikaflex stick to old Sikaflex? I've had great success with their products, but their website is the most user-hostile I've ever come across.

I hope you fixed your problem I am not surprised there were no replies to your question.

Sikaflex say there is nothing to remove their products 261 or 291 295 except by mechanical means only cutting/grinding. Long thin sharp blade, grinding wheel, (wheel not appropriate for your application)

They have a cleaner Remove - 208 that will remove it before it has cured. and also Remove - 208 hand /towels wipe.

On forums I have even read of baby wipes being used but I think that must have been used on un - cured Sikaflex if it worked at all personally I would try to use a good self amalgamating tape take it round the top edge completely so it all looks the same you can buy it in various colours. Sikaflex reckon you can sand their Sikaflex never tried it myself, that would clean it. don't forget to mask up
