Check the expiry date of your expanding foam...

Yes, that is an deliberately obscure title as clickbait... but bear with me.

I have an old three legged tubular metal equipment rack in the shed, and had an idea to employ it by filling the voids in the tubes with expanding foam to deaden the ringing and perhaps make it usable.

It did not go to plan... Having spent 2 hours cleaning hardened foam out of the applicator gun, I squished the foam liquid in only to have it eventually dribble out of the tubes, partially expanded in places, in others just smeary fluid, making a horrific mess of the kitchen table, the floor and me. Now have a headache from the solvent fumes.

Expiry date of the tin of foam was 2015!

If you need to clear expanding foam from nozzles or the top of the can, just soak them with meths. I've had old cans that worked fine.

Yes you should always test it somewhere safe to make sure its ok first.. I usually alway do this, even with new bought stuff as its a pig to clean off.

Sounds like me when I dug out my old silicone dispenser to redo the bathroom. Surely if you use half a tube doing it, you can expect to save the other half to redo it 5 years later?

They just make stuff to throw away these days and make you buy more, not like when I was young when everything lasted forever.

Like Summer holidays when I was at primary school

no doubt things are mostly made to a price, and even more so to a time scale now. if its guarenteed for 2 years it will last 25 months

Really don't know what to say to that. Oh yes I do - £2.50 a tube

The people who sell expanding foam will also sell foam gun cleaner - it comes in an aerosol tin and fits onto the gun. A short blast clears the old foam double quick. Squirted onto unwanted foam, new or old, that shit will dissolve immediately

You're thinking of the cheap crap, I'm talking about the TOTL branded quick setting non mildew variety. I think it was £8.99 or something.

I sealed my bath with the "cheap crap" (the same stuff I use for upvc windows) but spent large on a decent extractor fan. That was about 5 years ago, still looking good No black spots or anything
