Polyvinyl acetate adhesives are also known as PVA glue. The glue is usually white, though the yellow glue that is sold as carpenter's glue is the same thing. The fact that PVA glue does not create fumes and that it can bind a wide variety of substances have made it a popular choice among teachers and craftsmen alike.
PVA glue is used in schools frequently enough that is also referred to as school glue. Since it dries clear, it is an easy way to apply glitter to a craft project. It works well with construction paper, cotton balls and fabric. PVA glue can bind wood, vinyl, and most other craft material. When mixed with approximately 3/4 cup of water, it can be used to make the paste needed for a papier-mache project.
PVA glue is not only good for creating a craft project, it can also be used to make that project shine. A PVA glue varnish will help protect the surface of a craft without leaving a sticky residue. Mix one part water with three parts glue. Use a paintbrush to coat the craft. The mixture will look white when it is first applied, but it will dry clear.
Many bookbinding companies use PVA glue to bind their books. PVA glue is flexible, meaning the bindings will not turn brittle and crack easily. Therefore, the books will last longer. Because PVA glue is water soluble, it can be cleaned off easily. If glue spills on the book during the binding process, it is not automatically ruined. The one downside to using PVA glue to bind a book is that it does not dry quickly. The book needs to be clamped together after the glue is applied to achieve the best results.
PVA glue has some uses that may be surprising to some people. It can be used to protect cheese from fungi and humidity. It can be used as a gap filler when it is combined with sawdust. When diluted, it can be used as a sealant. One problem with working with plaster is that it can dry out too quickly. Using PVA glue as a sealant on the plaster will decrease the rate at which the plaster absorbs moisture, thus extending the length of time it can be manipulated.
