Hands up those who use adhesives and sealants regularly?
I would have said “as part of their trade” but, as it turns out, a snap poll round the boating world I live in sees them used in all sorts of places, by all manner of people, to do the most unusual of jobs!
For the most part glues and sealants tend to do exactly what they say on the tube or tin.
Well sort of.
That tiny writing, the bit I always have to squint to read, always says “Not suitable for” and a long string of “not to be used in conditions” seems to be industry SOP nowadays.
Now you’re probably thinking I’m going to list their uses and do’s and don’t.
Nope, not a chance, there ARE simply too many of them AND they tend to be country specific OR have different trade names.
Only my question is
“WHAT YOU GOING TO USE IF OR WHEN
YOU CAN’T SOURCE GLUES OR SEALANTS!”
Just think about it.
Chemical manufacturing may have been stopped by no electricity.
So once the stockpile of glues and sealants has been used up OR the shops aren’t trading as money can’t work for the same reason i.e. no electricity.
How exactly are you going to repair things if you are an avid glue and sealant user like me?
How did your elders “Do It”?
Animal products is a good source of “sticky stuff”.
Boiling down animal hides (rabbit hide produces a really “gooey” glue), bones, and tendons to produce a sticky ‘gelatinous like’ glue.
Only consider that glue is only a couple of boils up from gelatine and you find that as a binding agent throughout the food industry.
One word of warning, very few animal glues are waterproof.
Vegetable Glues aka Starch based goo.
My favourite is boiling down holly leaves.
This incredibly sticky goo is used for bird caps.
Just about any starchy food stuff can be reduced to a good glue.
Potatoes, rice, and wheat. Just boil, and keep on boiling.
OK, what’s next?
Resin from pine is good and has been used since “records began”.
It also burns even when wet.
Bees wax is better as a sealant and you can find that in bee hives (stings and all).
Stuff from combustion.
Burn green wood and it gives off a creosote tar.
That’s good as a sealant and preservative but is corrosive and flammable.
So that’s my knowledge expended about expedient glues and sealants.
So I’d appreciate some wisdom on other field expedient gooey type things.
Only nothing that needs “chemicals” or advanced techniques.
Think billy can and open fire sort of chemistry please.
