PVA glue, or polyvinyl acetate glue, is a popular adhesive used for various crafting and woodworking projects. It is a white, water-based glue that dries clear and is known for its strong bond on porous materials like paper, wood, and fabric. PVA glue is non-toxic and easy to clean up with water, making it a safe choice for both children and adults. This type of glue is often used in schools, homes, and workshops due to its versatility and effectiveness. Once dried, PVA glue becomes flexible and can withstand some moisture, but it is not waterproof. For outdoor projects, a waterproof variant is recommended.
