Anybody used Butyl instead of silicone

[Pagetslady]

Hi everyone I am having the tread master replaced on my Westerly Corsair, once it is finished I will have to refit all the deck fittings that I have removed, I really don't want to spoil the new tread master with Sikaflex so I am considering using Butyl tape seems a much more controllable product your opinion on this would be very much appreciated thank you in advance.

Butyl is a good sealant and fine for that job. Sika is not silicone (which is not suitable) but an adhesive/sealant that sets and will be just as effective as butyl. No need for it to be messy if you mask around the fitting.

Butyl tape is excellent - used it for bedding skin fittings, bedding P bracket, bedding windows and deck fittings.

Big fan of it but personally would not use below the waterline

Sika is a company which makes sealants, including silicone sealant.

I will be having to take my windows out this winter (Alloy frames with glass) The butyl rubber between frame & glass has gone hard & cracked up & they are starting to leak. They are 11 years old. Not impressed!

It's the only thing I use for deck fittings.

+1 for butyl above the waterline

Butyl for me too on deck fittings and windows/hatches and no problems over the last 7 years. Again I would not use below the waterline, prefering Sika for that, but that's just a personal opinion, it might be perfectly acceptable for those fittings too.

Sika "what?" they make a lot of products. Probably Sika 291.

I’ve used Arbo GZ tape and Arbo BR in a tube. Both have worked fine for me.

I bought generic double glazing butyl tape off eBay, seems fine. Arbormast is the top brand but the stuff in the tube although fantastic for the job gets absolutely everywhere.

Another for arbo br in a tube. I use it above and below the waterline with no problems.
