As a professional plumber with years of experience, I have encountered numerous situations where the wrong type of putty was used for a plumbing project. One common mistake that homeowners make is using plumber putty instead of silicone putty. While both types of putty serve a similar purpose, they have distinct differences that make them suitable for different applications. First and foremost, it's important to understand that silicone putty hardens and dries completely, while plumber putty always remains relatively soft and malleable. This means that when using plumber putty, you will have a more flexible seal that can easily be removed if needed.
However, this flexibility also means that it's not suitable for projects that require a firm, solid seal that doesn't move on contact. A common example of this is caulking around a shower or bathtub. In these areas, you want a seal that will not budge or shift when in contact with water or moisture. This is where silicone putty shines. Unlike plumber putty, it has a drying time and requires approximately 24 hours to fully cure.
This means that it will form a solid and durable seal that can withstand exposure to water and moisture. Another important difference between the two types of putty is their reaction to air. While silicone putty hardens when exposed to air, plumber putty does the opposite - it becomes brittle. This means that if you accidentally leave plumber putty exposed to air for too long, it will lose its malleability and become difficult to work with. In contrast, silicone putty will remain pliable until it is exposed to moisture. So, what happens if you do end up using plumber putty for a project that requires a solid seal? Well, it's not the end of the world.
There are ways to remove plumber putty, but it will require some extra effort. One method is to use a hair dryer or heat gun to soften the putty and make it easier to remove. However, this can be time-consuming and may not always be effective. As a professional plumber, I always recommend using the right type of putty for each specific project. This not only ensures a proper and long-lasting seal but also saves you time and effort in the long run.
So, before starting any plumbing project, make sure to choose the right putty for the job.
