When tackling plumbing projects, one material you’ll often hear about is plumber’s putty. You might be wondering, what is plumber’s putty? How does it work? And, more importantly, why do professional plumbers in Melbourne swear by it for sealing plumbing fixtures? 

This blog covers everything you need to know about plumber’s putty, its uses, and how it can ensure a leak-free and efficient plumbing system.

What Is Plumber’s Putty?

In simple terms, plumber’s putty is a flexible, moldable substance that’s used to create a watertight seal in various plumbing fixtures. If you’re installing a faucet or sealing a drain, plumber’s putty forms a strong bond that prevents water from leaking out of joints and connections. The substance itself can be easily shaped to fit around areas that need sealing.

It’s important to note that plumber’s putty isn’t adhesive. It doesn’t stick things together, but instead, it seals off gaps between surfaces. This ability to seal gaps without hardening over time makes it an indispensable tool for many plumbing tasks.

How Does Plumber’s Putty Work?

Plumber’s putty works by filling the tiny gaps between surfaces that need to be sealed. When applied to the area needing a seal, such as the base of a faucet or around a sink drain, the putty is compressed, and the excess is squeezed out. This process ensures that the putty fills every nook and cranny, creating a secure, watertight seal that prevents leaks.

What makes plumber’s putty great is its versatility. It doesn’t dry hard like some other sealants. Instead, it remains pliable for years, which is why it is perfect for plumbing installations. 

Common Uses of Plumber’s Putty

  • Sealing Faucets
  • Installing Sink Basket Strainers
  • Sealing Pop-Up Drains.
  • Shower Drain Installations

Why is Plumber’s Putty So Effective?

  • Long-Lasting Seal: The flexibility of the putty means that it can hold up for years without cracking or losing its sealing ability.
  • No Drying Time: Unlike other sealants that require curing time, plumber’s putty is immediately effective after application. There’s no waiting around for it to dry.
  • Easy to Remove and Reapply: If you need to make adjustments or repairs, plumber’s putty can be easily removed and reapplied without leaving any residue behind.

How to Use Plumber’s Putty

When using plumber’s putty, follow these steps for optimal results:

1. Surface Preparation

Before applying plumber’s putty, make sure the surface is clean and dry. Any dirt or grease can prevent the putty from forming a secure seal. 

2. Portion Control

Take a small amount of putty from the container. After using it, make sure to seal the container tightly to prevent it from drying out.

3. Kneading and Shaping

To make the putty easier to work with, knead it in your hands for a few moments. This warms it up and makes it more pliable. Roll the kneaded putty into a rope shape about half an inch thick. The size of the rope can be adjusted depending on the gap you’re sealing.

4. Application

Once you have your putty shaped, place the rope around the underside of the fixture you’re installing. Make sure there are no gaps in the rope, and press it firmly into place.

5. Compression

Once the fixture is in place, press it down firmly. The pressure will cause the putty to spread and fill the gaps, forming a leak-proof seal. You’ll notice excess putty oozing out from under the fixture, which is a sign that you’ve used enough.

6. Clean-Up

Use a clean cloth to wipe away any excess putty. Make sure that the area is neat and clean. The last thing you want is visible putty stains around your plumbing fixtures.

7. Final Adjustments

In colder conditions, wait for about 10 minutes after installation. Then, check if the fixture needs an extra twist or turn to ensure the seal is tight.  Cold weather can make the putty less flexible, so this step helps ensure a tight seal.

What Surfaces Should You Avoid Using Plumber’s Putty On?

Though plumber’s putty is a versatile and useful tool, there are a few surfaces on which it should not be used:

  • Plastic: Plumber’s putty should not be applied to plastic surfaces, such as PVC or ABS piping. It can cause damage or create an imperfect seal.
  • Porous Materials: Surfaces like marble, granite, and quartz can absorb the oil in plumber’s putty, causing stains that are difficult to remove. When working near these surfaces, use a stain-free plumber’s putty that doesn’t contain oils to avoid damage.

Situations Where You Need a Professional Plumber

Though plumber’s putty is an excellent tool for sealing joints and fixtures, it’s not the solution for every plumbing issue. Here are a few situations where you should call a professional plumber:

  • Pressurised Plumbing: If you’re working with pressurised connections or pipe threads, plumber’s putty isn’t suitable. You’ll need a more specialised sealant.
  • Large-Scale Installations or Repairs: If your plumbing issue requires a major installation or large repairs, it’s best to leave it to the professionals who have the right tools and expertise.
  • Persistent Leaks: If you’re facing persistent water leaks that plumber’s putty cannot fix, there could be an underlying problem like damaged pipes that requires professional attention.

Conclusion
