What sealant (1 Viewer)

[Reallyretired]

I have a loose bit of sealant on the roof of the Rapido in the joint between the front roof moulding and the main flat roof section.
What sealant would the expert panel recommend. Some sort of sikaflex suggests itself but which one?

Are you going to Peterborough? I have 3 tubes of Sikaflex 221 up for grabs:

Afraid not going to pboro but is that the one I need?
I would like to fix pronto as off to France next week. Booked on impulse an hour ago from C a nterbury c&cc site. Can only be away 15days but can go again mid May.

I can't see why it wouldn't work fine for your purpose, the below Sikaflex link gives details of it's application:

I can post them if you want, shouldn't cost much.

Sikaflex 221 is more of an adhesive than a sealant. Also make sure whatever you use is in date.

I would use Hodgesons flexible caravan sealant. Its a flexible non-drying sealant only, ie not an adhesive. Available from any good caravan accessory dealer.

I Have used sikaflex 512 adhesive and sealant with very good results and would recommend it. If you had occasion to remove the cover strip on the ceiling inside as I did once, to reseal the aerial fitting, you would see that the joint has filled and sealed with a white rubbery material which is similar to or even may be Sikaflex 512. This is the same stuff you can see in the joint when you are outside on the roof.

I've used Puraflex 40 successfully after recommendation from @Terry.

Although Sikaflex has been around a long time and is without doubt a good product, but there is these days a lot of cheaper competition... I have used the excellent Tec7 for some time which is basically an M7 polymer based Adhesive, it can be used as a sealer but not recommend where flexibility is required......for sealer situations you can use a Butyl flexible sealer or
Geocel Silicone Rubber sealer which most yachting/boat yard's in this district use
