Is Elmer's glue waterproof

Elmer's glue is not waterproof; it is water-soluble and can dissolve or weaken when exposed to moisture. However, there are specific products in the Elmer's line, such as Elmer's Carpenter's Wood Glue, that are labeled as water-resistant or waterproof for certain applications. For projects requiring waterproof adhesion, it's best to choose a glue specifically designed for that purpose.
