Description

Plumber's Goop is applied directly to the material that needs to be sealed, and a small amount is usually sufficient. It is clear and waterproof when dry, and maintains a flexible feel. Unlike other sealants, it does not turn yellow after time. Goop is able to withstand temperatures as low at minus 40 and up to 150 degrees Fahrenheit, and is acid-resistant. As the toluene evaporates over time, the Goop will shrink.

Dilution

The remaining Goop left in a partially used tube can harden, but it can be easily brought back to its normal state by mixing in some more toluene, which you can purchase at paint, hardware and hobby stores. Goop can be diluted with toluene until it reaches the consistency you need for a project. For example, sealing two water pipes together for plumbing requires full-strength Goop, but bonding a delicate glass piece might need a highly diluted mixture.

Application

It takes up to 72 hours for Plumber's Goop to fully dry and bond, but for many uses one to two hours is sufficient time. Humidity and air temperature affect the drying time. Several thin layers can be applied to a project, but each layer should have three to four hours to dry. According to Eclectic Products, Plumber's Goop is best applied when the temperature is between 50 and 90 degrees Fahrenheit.

Hazards

Vapors from Plumber's Goop are harmful to the respiratory system, so it should only be used in a well-ventilated area. It may also be irritating to skin and eyes if it comes in contact with them. You should wash your hands after every use. Goop is flammable and should be kept away from an open fire, sparks or heat. Smoking, eating or drinking around Goop is not recommended by the manufacturer.
