Fantastic sealant that's easy to apply, sticks to all sound substrates and totally durable.
Great, easy adhesion to all plastics, wood and metal substrates, where it touches it sticks to and is easily smoothed over to that perfect concave profile. The Sikaflex 512 is a better adhesive but difficult to profile. this 221 really is a great replacement for a more expensive alternative product.Read full review

Great product just what I needed to fix my awning rail to my Bongo. No need to drill holes in it so no water leaks. Job done

Sikaflex
This stuff is pretty good. I’ve been using it on a recent fibreglass project and it adheres the pieces together very nicely…the only drawback is that it takes so long to cure…24-48 hours….if time isn’t a factor then this stuff seems great. Fortunately I’ve just stuck my pieces and left them for another day to work on. Read full review

Sikaflex 221 general use
Been using this for twenty years on & off. Brilliant strong stuff. Worth the extra over the normal diy stuff - lots of data a available on the web. My latest was fixing alloy angle brackets onto concrete posts (without drilling holes ) to carry vine wires.Read full review

Fix it ONCE with this stuff
Recommended to me years ago by auto mechanics.... lots of other products will do the job but years down the road my job will still be solid... I trust these guys. It’s the tolerance of vibration that sets this product apart from all others imoRead full review

Sikaflex.
This product is superb to use on Camper vans for sealing purposes. However, the metal casing which contains the product WILL rupture. I have purchased six of these and every tube has ruptured. Make sure you wear gloves unless you want sealant ridden hands for three days.Read full review

Easy and practical
I used Sikaflex when fitting new roof vent in motorhome. Found it very easy to use and it seals well.

Excellent sealant
Recommended by my Eriba dealer this sealant/bonding is perfect for sealing and bonding holes and trim on the caravan.
Only thing to watch it seems to 'go off' in the tube quicker than normal mastics.Read full review
