Expanding foam

[lenallen]

Any help please, I have a large tin of expanding foam ( a small amount has been used ). It looks like I never cleaned the nozzle good enough because I cant get any more out of it......Any Idea's how to get over this Please

Yes, throw it away.

It is more hassle to try and clean it than it is to buy another tin of the stuff. By its very nature it sets hard after being exposed to air, whic also includes the tiny pipe coming out of the tin itself.

You may be able to use nail varnish remover but the time it will take, dont bother, and next time use a smaller tin

For what it worth, there is a foam cleaner here

"Expanding Foam Gun Cleaner Aerosol is a specifically designed cleaner fluid for the cleaning of uncured polyurethane foam from foam applicator guns."

why dont they ever give you extra tubes with the cans of the stuff? is it perhaps because they know it clogs up and you end up throwing a half used can away and buying a new one.....no surely not!

A tip - when you use this stuff stuff a pipe cleaner down the long pipe, remove the nozzle and stick a couple of screws in the ends, and one in the small pipe on the top of the can when you've finished. That way you might be able to use it next time.

Alternatively buy a gun and some solvent and wash out religiously each time you use it, and never leave the can on the side for more than a few weeks as the pressure will go

Have you ever wondered why half the tins on the shelf at the hardware store are missing their tubes........?
