Every type of adhesive has its pros and cons; from simple wood glue to fiber-reinforced epoxy, they all have their proper use. Some adhesives act as a separate layer that applies a
gripping strength to the items via any imperfections in the surface, while others
actually soften the edges of the parts and meld them together, forming a type of chemical weld.
While all sorts of adhesives are currently available through the
normal course of commerce, that may not always be the case. The ability to make some of the more basic glues and pastes can be of great benefit to preppers.
One of the simplest is classic flour-based wallpaper paste, also
useful in crafts like papier mache.
- Combine 5 cups flour and 1 cup of sugar in a large pot.
- Place over low heat.
- Slowly add 1 gallon water, using a whisk to break down any lumps.
- Cook until nearly clear.
- Let cool to room temperature.
There are a variety of other adhesives that can be made at home. Particularly useful is a water-resistant glue made using pine
resin as its main ingredient.
- Collect pine resin (aka sap).
- Melt the resin. Try to not overheat it, as the compounds are destroyed the longer they're subjected to heat.
- Be careful! The resin can ignite if placed too close to open flame.
- Add 1 part powdered hardwood charcoal. This helps temper the resin and reduces its stickiness.
- Add 1 part filler material. This can be ground plant material (crushed to a fine powder) or animal droppings (dried and ground up). Sawdust, bone dust, or animal hair can also be used. The filler material helps strengthen the glue compound.
- To make the glue more flexible, add one part fat, tallow, or beeswax to the mixture.
- Mix thoroughly.
- After the glue hardens, it will resemble hardened glass (if beeswax or fat were added, it will be more elastic).
While some of the simpler adhesives, such as the flour-based
glue I mentioned above, are weaker and less permanent, others can provide a much longer-term bond.
I hope I don't sound tacky, but stick around for more tips
and tricks.
