White glue is a water-based adhesive, which makes it easy to dilute with water for a more fluid consistency. However, this same property can make it vulnerable to exposure to water. The long chains of molecules that make up PVA glue are held together by hydrogen bonds. When these bonds come into contact with water, they break down and cause the glue to lose its adhesive properties.

While white glue is somewhat water-resistant, it cannot withstand prolonged exposure to water or complete immersion in water. Therefore, if you need an adhesive that provides long-term protection against exposure to water, white glue may not be the best option.

You can boost the water-resistance of white glue in a number of ways. One method is to mix it with other substances that enhance its waterproofing capabilities, such as silicone sealant or acrylic paint. Another method is to apply a sealant on top of the dried glue using products like varnish or clear polyurethane spray.
