Wheat paste is a glue that can be made from common materials. Prepare 1 cup (2.4 dl) of very hot water. Make a thin mixture of 3 tablespoons (45 ml) of white flour and cold water (just enough to wet all the flour and make it liquid enough to pour). Pour the cold mixture slowly into the hot water while stirring constantly. Bring to a boil. When it thickens, allow to cool. Smear on like any other glue. For slightly better strength, add 1 tablespoon (15 ml) of sugar after the glue is thickened. After using a portion, reheat the remaining in a covered jar or container to sterilize it for storage or keep refrigerated. If wheat flour is not available, other flours will work.

Other variations[]

  • Rice paste (Mix one part rice flour and six parts water. Heat while mixing to a smooth consistency.)
  • Acacia tree gum
  • Sylvian Kimour reports from the Democratic Republic of the Congo that cassava flour works even better than wheat flour, which is very expensive there.

In 1990, the University of Washington measured the holding power of various adhesives:

Adhesive Peel Test
Rice Paste 7.9 lbs
Wheat Paste 8.1 lbs
White Glue (full strength) 7.5 lbs
White Glue (diluted 1:1 with water) 8.1
