Sealant for poly / rotamoulded kayak

Post by tommfuller » Mon May 23, 2011 4:06 pm

Hi Folks,

I need to seal around some bolts and screws I've put into a poly kayak, any reccomendations for what sort of sealant I should use? I hope the compression on the fitting should provide quite a good seal but I'd like to make it as good as possible. I know most glues don't stick to poly - are there any that do? If not I'll just need to rely on some sealant forming a plug the right shape as it goes off.

Cheers,

Tom.

Ive used Stikaflex to seal the bullkheads on my boat.

Also had a couple of leaky screws where the foot rests bolt in.

I filled the hole and drove the screw home, the sealant forced out acts like a sealing washer.

Alternatively some neoprene washers if you can get them would do the job.

Valley supplied me with Sikaflex 291 to repair a poly kayak, its what they use in the factory.
