What adhesive?

[Shiver Metimbers]

I need to secure the gas pipe from the gas locker down to the lounge as it is just flapping about. I am looking at gluing 30/40mm squares of 13mm ply to the inside of the hull and secure the pipe to this using screws and pipe clips. What would be the best adhesive?

Thanks in advance.

I use epoxy for almost everything nowadays. It sticks to most things that boats are built from. Expensive but lasts forever; you will need to thicken it with microspheres or cellulose fibres to turn the resin into a gap filling adhesive and colloidal silica to make it nice and thick so your pads don't slide off before the adhesive dries. West System is the most popular and most expensive or try SP 106 made by Gurit - cheaper, but most chandlers stock the additives by Wests. You need to be fairly quick to use it unless you get a slow acting hardner.
Or you could just try Araldite which is an already thick epoxy.

Any polyurethane goo will do.Polisulphide sealant is also good.Male sure the surfaces are clean,stick the ply squares in place and hold them with tape while the sealant cures.Usually takes 24hours.

I've used car body filler with perfect results. Sets quickly in warm weather (too quickly sometimes) esp if you are generous with the hardener. Can be warmed cautiously with a hot air gun if cold. Warm, hold inplace for a couple of minutes and its fixed!

But for the need to hold for hold for 24 hours Id go with the suggestion to use a modern polyurethane adhesive from a cartridge gun. Evostick "Serious stuff" ?

Hot melt glue gun ? Got one, never used it yet though!

I use serious stuff on woodwork. (The exterior grade)
As for sticking stuff in, car filler is a good idea, as is epoxy or araldite, i have a glue gun that i use, but should really only be for temporary fixing as the bond isn't that strong.
I use it to hold mini-bulkheads and stuff in place while i glass/bond them in!

I fixed my gas pipe in the same way as you are proposing using Plastic Padding Fibre Glass Filler - the green stuff in a tube that you mix with the hardener. It's thick enough to hold the wooden blocks in place whilst it sets and is very convenient to mix up the right amount to fit your work rate. This is probably not the 'best' product. West System epoxy with microfibres would be stronger.

I roughed up the base of the blocks and the surface of the hull (after cleaning) with course sandpaper to help ensure a good bond. The pipe was then fixed to the blocks using copper pipe clips.

How about "Quick(Five minute)" setting "Araldite" epoxy, two pack (in the one gun)? Works for me!

No more nails or equivalent will also work well.
