Review: Excellent for campervan - Great adhesion and sealant, perfect for sticking campervan batons and really all things camper. I tested this by laying a piece of 2 x 1 on van metal floor and came back the next day to see what it would take to pull it off. Well it took about minutes bashing it with a hammer and edge tools. It was really, really stuck on there. Where i could used this stuff and screws for absolutely going nowhere fit, especially if anything was being mounted.

## Questions & Answers

**Q: Can this be applied over existing silicone**
A: I always clean old stuff of first then apply

**Q: Can you use for roof rail sealant for VW micro camper(caddy)?**
A: I would use it as I repaired my roof to gutter seam with it and have had no issues yet and that's a couple of months ago

**Q: We need to reseal our whole motorhome around all the joints etc. How many packs of this would we need? The Moho is 7.5m long. Thanks**
A: Depends upon what size gaps you’re going to seal. Very sticky, I’d start with two and smooth it in. You could always get more if needed.

**Q: Can silka522 be overpainted**
A: Overpainting. Sikaflex®-522 can be best painted within the skin formation time. If painting process takes place after the sealant has built a skin, adhesion could be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 prior to paint process.

### ⭐⭐⭐⭐ TRUSTWORTHY STUFF.
*by P***. on 17 July 2026*

Sika Sikaflex-522 Caravan & Motorhome Adhesive Sealant.Used this many Times and always moan that its too expensive, but it does the Job without letting you down.You have to Clean with degreaser and Alcohol the surface and work very Quick (certainly in this Heat Wave) and make sure it goes Down Once,as your not going to move it. Only use were it Touches the Roof,(use polysulphide Tape to build up in the Ridges and stick down).Keep it weighted down overnight before you hit the Motorway at 70 mph and it will stay on without Drilling Holes in your Roof,that will leak eventually.Good Stuff.
