What do users say? AI-generated summary

Users find that Sikaflex 11 FC seals effectively and provides strong adhesion. It is often recommended for sealing exterior frames and gaps, and for withstanding harsh weather conditions.

  • I have used it in a storage shed with panels that I built in 2021. I also put it on the PVC frames for sealing, and around every hole and gap all around. The shed is at an altitude of 1,400 m with a lot of snow in winter! Guys, I open the door and I don’t even find a spider! After so many years, it’s the best thing I’ve tried!

  • Great caution. Always wear dishwashing gloves. It stuck to my hands and it doesn't come off.
    In the end, it came off with the polyurethane solvent I bought for 4€
