Sikaflex-522 weather-resistant, UV-stable, adhesive sealant (new version of Sikaflex-521 UV and Sikaflex-221i) 300ml black

Great product came recommended, used this to fix a pipe top on my camper, clamped it overnight for the best results

We have used this extensively on our campervan to seal installations such as the roof vent and solar panel cable entry gland. It’s easy to apply, provides a good colour match with our roof vent and solar panel cable entry gland, and so far has been waterproof. For the price it’s really not worth messing around with cheaper alternatives.

Good for the job and easy to use with the a good quality gun

Sticks stuff together, smells great

very strong glue, great value for money, ive used it during my camper conversion

Sadly my 21 year old car developed a leak from the roof due to a rust hole around the sunroof! After much research I chose this product to seal the hole and for good measure all around the sunroof - it is asking a lot really because as you know a huge metal area that gets extremely hot in the sun, then cold is subject to extreme thermal stress and expansion.I am glad to report that it worked perfectly and still is almost one year on with no signs that it will fail either. The flex in the sealant and UV resistance made this the right product for me, also being clear it hardly shows at all - not that one can care too much when driving a 21 year old rust bucket VW!!

High quality sealant with the flexibility for the movement in a caravan.

Sikaflex is one of the top products for seali g caravans and done it's job well caravan is sealed up for another while
