Picture of Homemade Flame retardant

This is my first instructable, so please bear with me.  Many times in the course of building / re-purposing items for various projects I have encountered a need to add some level of flame resistance to certain elements of the project.

While this procedure won't make any items flame proof, it will minimize the probability of ignition significantly. In this tutorial I will offer a possible solution for flammability problems along with the recipe and the results from a quick and dirty experiment. This technique will only work for natural materials such as wood, cotton, jute, and paper or the like. It will not work for synthetic materials such as polyester, nylon, polypropylene or anything else that did not originally come from a plant or tree.

 

Step 1: What you will need

Picture of What you will need

Borax (sodium borate) laundry booster

A measuring cup

A 1 Tablespoon measuring spoon

An old sauce pan

A storage container

Some sort of applicator ( paint brush, spray bottle, etc)

 

Step 2: Procedure

You want to make a saturated solution

Boil 1 cup of water

Add 2.5 tablespoons of Borax to the boiling water

Stir until the Borax dissolves

Allow to cool to room temperature

Pour into storage container or spray bottle.

Step 3: Application

You can use a spray bottle or brush

Wet the heck out of the item to be protected. Make sure it is saturated.

If you run out of solution, make more, because the item has to be absolutely positively soaked.

When you think its wet enough, wet it some more

Allow to dry

Once the solution dries, it is very important to keep it dry as any water contact will wash the protection off.

Great instructable!
Most recipes include adding boric acid to the solution.
