Homemade mod podge is made with either a glue or flour base. The flour-based recipe requires cooking while the glue-based recipe only requires mixing ingredients together. Mod podge is an all-in-one glue, sealer and finish for decoupage projects.
The ingredients for glue-based mod podge are 8 ounces of glue and 4 ounces of water. The project also requires a jar with a tight-fitting lid. This recipe creates a matte-finish mod podge.
Empty the glue into a clean jar. A good tip to make the glue easier to pour is to place the bottle in the microwave for 20 to 30 seconds prior to pouring it out. Once all of the glue is in the jar, add the water; stir to combine. If a shiny finish is desired, 2 tablespoons of water-based varnish can be added. Close and shake the jar.
The ingredients for flour-based mod podge are 1.5 cups of flour, 1/4 cup of sugar and 1 cup of cold water. A jar with a tight-fitting lid is also needed. Place the flour and sugar in a pot, but do not turn on the stove. Add the water, and whisk thoroughly to mix the ingredients together and remove clumps.
Turn the stove on to medium heat, and continue to stir. Do not let the mixture boil. If the mixture becomes too thick, add some water.
To create a shiny finish, add 1/4 teaspoon of oil to the mixture as it cooks on the stove. Let the mixture completely cool before pouring into the jar and sealing. The flour-based mod podge should be stored in the refrigerator since it is made of natural ingredients and can rot.
