What is the best glue to use for Outdoor Swimming Pools Spas and Pool Equipment Plumbing

Many may not realize that adhesive color can be customized for specific applications. To avoid confusion, we recommend using model #711 Gray glue and P70 Purple primer for swimming pools, spas, and outdoor projects. This recommendation is based on insights gained from tens of thousands of inspections, making it the best practice for chlorinated environments and outdoor use.

For leak-proof results, our proven choice is gray glue paired with purple primer. This combination ensures reliability and virtually eliminates the need for warranty service calls due to leaks or faulty plumbing connections.

Our application method involves thoroughly priming, with approximately 10 to 50 rotations around the ends of both pipes, always starting with the female fitting first with primer then last with glue. This approach ensures optimal surface preparation for bonding.

Using the specified glue and primer allows for pressure testing within 2 to 10 minutes, depending on ambient temperature. In cooler conditions, allow 10 minutes or more, while warmer temperatures may permit testing as soon as two minutes.

Apply both products generously, but avoid excessive use of glue. The glue serves as more of a lubricant, while the primer functions as the true adhesive. Priming thoroughly with minimal glue application often results in better outcomes as the primer is melting the plastic allowing it to fuse with itself once dry.

For large-scale pool projects, anticipate needing approximately 1 gallon of each product, plus an additional quart for refills. When used consistently, glue and primer should maintain an ideal consistency—similar to yogurt for the glue and wine for the primer. If the adhesive dries out, it may become less effective.

We advise against using clear glue and primer. These products lack visibility, making it easy to miss a proper connection, leading to potential “dry joints.” According to swimming pool leak detection specialists, missing glue joints are among the top three causes of leaks.

Lastly, clear adhesives tend to degrade under UV exposure, especially outdoors. Over a period of 10-20 years, they can lose their effectiveness, leading to leaks—commonly seen on outdoor swimming pool equipment pads.
