How long does plumber's putty take to dry?

What is plumber’s putty?

Plumber's putty is a convenient and versatile sealing compound widely used in plumbing to create a watertight seal around fixtures and pipes to prevent leaks. It works by filling in the space between two surfaces so water cannot penetrate.

Most often, you'll see it used to seal the space around drains, faucets, sink basket strainers, and pop-up drains. Once in place, plumber's putty prevents water leaks and helps to stabilize fixtures.

Plumber's putty is usually sold in plastic tubs. When you open the container, you'll see a gray substance that's soft and malleable. The putty is primarily derived from organic clay mixed with ingredients like talc, limestone, and linseed oil to ensure it can be easily shaped and molded to the user's specifications.

How to use plumber's putty. 

It's easy to use plumbing putty as long as you follow a few simple steps:

1. Clean the surfaces where it will be attached. If there's any existing putty, it's crucial to scrape it off thoroughly so the new putty can get a clean seal.
2. Create a putty rope. Scoop some putty from the container and roll it into a rope. As you're rolling the putty, try to keep the shape consistent, so one area isn't thicker than another.
3. Apply the plumber's putty. Once you have an even rope, wrap it around the base of your faucet, drain, or other plumbing component. After you have evenly applied the putty to the area, press it gently into place.
4. From there, apply the plumbing part as required. Install the part or piece that needs to be sealed. If the putty squishes out, that's ok.
5. Let it sit. Once the putty has been applied and the part is in place, it's best to give it at least 10 minutes to cure, particularly if you're in a cold area. This waiting time ensures your putty molds to the proper shape.

When to use plumber's putty (and when not to). 

Plumber's putty is ideal for many plumbing-related applications, including any situation where a pliable, non-hardening sealant is needed. Because the putty does not harden but remains watertight, it can be modified over time if adjustments are required.

However, it should never be used on threaded pipes, as it may interfere with proper sealing mechanisms like rubber gaskets or washers. Additionally, plumber's putty is not suitable for use with materials like granite, marble, or plastics because it will affect their integrity and cause long-term damage and stains.

In situations requiring a rigid, long-lasting seal, other products (like silicone or pipe thread sealant) are more appropriate.

Mistakes to avoid when using plumber's putty.

Using plumber's putty is fairly intuitive, but it's still possible to make mistakes. Here are a few to avoid:

• Using it on threaded joints. Avoid using plumber's putty on threaded connections, as it can interfere with the proper function of gaskets and washers in those areas.
• Applying putty to incompatible surfaces. Plumber's putty is unsuitable for use on materials like granite, marble, or plastic, as it could cause discoloration or damage. 
• Neglecting to tighten connections. Plumber's putty is not a substitute for proper tightening. After application, ensure all fixtures are securely fastened.
• Using as a permanent or pressurized sealant. While effective, plumber's putty is not suitable for permanent or pressurized seals. Instead, opt for silicone or other appropriate sealants for long-term, high-pressure connections.
• Skipping cleanup. Failure to quickly remove excess putty after installation can result in an untidy appearance. It can become more challenging to clean the longer it stays in place.
• Improper storage. Seal the container tightly after use to prevent the putty from drying out. This will help it maintain its pliability for future applications.
