What is Polyvinyl Acetate Adhesive? (with photos)

Polyvinyl acetate adhesive, commonly used in woodworking projects, is a type of glue that can be purchased by the bottle.

Polyvinyl acetate, also known as PVA or PVAc, is a synthetic polymer or plastic. It is more specifically classified as a thermoplastic, meaning it melts at high temperatures and has certain properties, such as being elastic and flexible at room temperature. Polyvinyl Acetate Adhesive is a glue that contains this compound. Many common types of glue, including standard white glue or school glue, contain this material. Yellow carpenter’s glue, commonly used in woodworking projects, is also a polyvinyl acetate adhesive, as is the similar white wood glue. PVA glues are considered very easy to use as they can be cleaned with water, are safe to handle without gloves or other skin protection, and do not give off dangerous fumes, but they do not hold up well in damp or wet conditions.

PVA glue, which does not contain acid, is often used to make glues.

A polyvinyl acetate adhesive works best on porous materials such as wood, paper and cardboard, and is also recommended when gluing vinyl and leather. Many PVA glues are white and are used for a wide variety of purposes, such as making collages, paper crafts, and woodworking projects. These adhesives are acid-free, making them especially suitable for projects such as bookbinding, where an acidic adhesive would deteriorate the paper.

Carpenter’s glue can be safely handled without gloves.

Yellow carpenter’s glue is commonly used for both do-it-yourself home construction projects and woodworking projects such as furniture making. This glue retains its yellow color when it dries, while a white adhesive dries clear. White PVA glue also has a longer drying time than yellow glue. Both work well for most types of wood, but do not always provide a strong bond if the wood is oily, such as teak. The water content of the adhesive can also cause some types of wood, such as beech, to become warped.

PVA is sometimes used to affix paper cut designs to craft projects.

In order for a PVA glue to form as strong an adhesive bond as possible, the user must work at room temperature, ensure good air circulation and apply pressure to the materials being glued, for example using staples. This type of adhesive is not suitable for use in places where it will be exposed to moisture or water. It should also not freeze, as this will cause the glue to lose its ability to form a strong bond.
