When it comes to bathroom repair materials, plumber’s putty often sits at the top of the list—but it behaves very differently from what most people expect.

Article Breakdown
What Is Plumber’s Putty?
Let’s start with the basics. Plumber’s putty is a soft, moldable, oil-based sealing material used to create watertight seals around plumbing fixtures. Think sink drains, faucets, or even bathtub drains. It’s been a staple in the plumbing world for decades, and for good reason, it’s affordable, easy to use, and incredibly effective when applied correctly.
Here’s a little backstory: The first time I used plumber’s putty, I was helping a friend install a new kitchen sink. We were both DIY novices at the time, and let’s just say the learning curve was steep. I remember rolling the putty into a long, thin snake and applying it to the drain flange, only to second-guess myself moments later. Was I supposed to wait for it to dry? Did I need to let it cure overnight? Spoiler alert: I didn’t, and everything worked out just fine.
Does Plumber’s Putty Dry?
Here’s the big reveal: plumber’s putty doesn’t dry. Instead, it stays soft and pliable indefinitely. This is what makes it so effective, it remains flexible, allowing it to adapt to the slight movements and shifts that naturally occur in plumbing fixtures over time.
Why Doesn’t It Dry?
Plumber’s putty is oil-based, which prevents it from hardening like silicone or other sealants. This unique property makes it ideal for creating temporary or semi-permanent seals that can be adjusted or removed later.
When Is It “Ready” to Use?
While it doesn’t dry, you can use plumber’s putty immediately after application. Once you’ve applied it and secured the fixture (like tightening a drain), the seal is essentially good to go. There’s no waiting period, no curing time, just instant functionality.
Step-by-Step Guide to Applying Plumber’s Putty
Applying plumber’s putty is straightforward, but there’s an art to getting it just right. Here’s a step-by-step guide based on my own experiences (and a few early mistakes I’d prefer to forget).
Step 1: Gather Your Tools
Before you start, make sure you have everything you need:
- A tub of plumber’s putty
- A putty knife or plastic scraper
- A clean cloth or paper towel
Step 2: Prep the Surface
Clean the area where you’ll be applying the putty. Dirt, grease, or moisture can interfere with the seal, so take a moment to wipe everything down.
Pro Tip: If you’re sealing a sink drain, make sure the surface is completely dry. Even a little water can compromise the effectiveness of the putty.
Step 3: Roll the Putty
Scoop out a small amount of plumber’s putty and roll it between your hands to form a long, thin rope (about the thickness of a pencil). This step brought me back to my Play-Doh days as a kid, so satisfying.
Step 4: Apply the Putty
Place the rolled putty around the edge of the fixture, such as the underside of a sink drain flange. Press it gently to ensure it adheres evenly.
Step 5: Secure the Fixture
Position the fixture in place and tighten it according to the manufacturer’s instructions. As you tighten, the putty will compress, creating a watertight seal.
Step 6: Remove Excess Putty
Use a putty knife or your fingers to remove any excess putty that squeezes out around the edges. Wipe the area clean with a cloth for a neat finish.
And that’s it! Your seal is ready to go, no drying or curing required.
Plumber’s Putty vs. Silicone: Which One Should You Use?
One of the most common questions I get is, “Should I use plumber’s putty or silicone?” The answer depends on your specific project. Let’s break it down.
| Feature | Plumber’s Putty | Silicone Caulk |
|---|---|---|
| Drying/Curing Time | None | 24-48 hours |
| Flexibility | Stays pliable | Becomes rigid when cured |
| Water Resistance | Excellent | Excellent when cured |
| Reusability | Can be removed/reapplied | Permanent once cured |
| Best For | Sink drains, faucets | Shower edges, vertical surfaces |
My Take
I prefer plumber’s putty for fixtures that might need adjustments later, like sink drains. For permanent seals, especially on vertical surfaces, silicone is the way to go.
Common Questions About Plumber’s Putty
Let’s tackle some of the most frequently asked questions about plumber’s putty.
Can Plumber’s Putty Be Used on Plastic Fixtures?
Not always. The oils in plumber’s putty can sometimes damage plastic, so check the manufacturer’s recommendations. If in doubt, opt for a non-staining putty or silicone.
Does Plumber’s Putty Work Underwater?
No, plumber’s putty isn’t designed for submerged applications. For underwater use, silicone or epoxy putty is a better choice.
How Do You Remove Old Plumber’s Putty?
Scrape off the old putty with a plastic scraper or putty knife. If it’s stubborn, use rubbing alcohol or soapy water to clean the residue.
Pro Tips for Using Plumber’s Putty Like a Pro
Over the years, I’ve picked up a few tricks to make using plumber’s putty easier and more effective. Here are my top tips:
- Knead Before Use: If the putty feels stiff, knead it in your hands for a minute to warm it up and make it more pliable.
- Use the Right Amount: Too much putty can create a mess, while too little won’t form a proper seal. Aim for a rope slightly thicker than the edge of the fixture.
- Check the Label: Some plumber’s putty is labeled “non-staining,” which is ideal for materials like granite or marble.
- Test for Leaks: After securing the fixture, run water to ensure there are no leaks. If you spot one, tighten the fixture slightly or reapply the putty.
