The Perfect Use Of Plumber’s Putty

The plumbers mainly apply the plumber’s putty on sinks, pop-up drains, and faucets. The other name for this component is “sink drain putty.” 

The plumber’s putty has been specifically designed to fix the specific plumbing issues. You can use it to stop small leaks, but it won’t be efficient in all situations, like sealing pipes with pressurized water. 

Plumbers also apply it before installing a faucet or sink since it saves effort and time. Plus, it protects the drain’s upper part because of its waterproofing qualities. The plumber’s putty is applied by simply rolling it to a narrow and snake-like shape.

Things To Consider Before Using The Plumber’s Putty 

You should consider two main factors before applying the plumber’s putty to your sink, faucet, etc.

1. Clean surface 

Before applying the plumber’s putty, you need to clean the surface and remove any undesirable particulates thoroughly. It’s because they can cause holes in the putty after some time. 

The best way to clean is by wiping the surface with a wet rag, then cleaning with a dry piece of cloth after applying the plumber’s putty. The cleaning process is essential, and you should never ignore it since it might bring issues later. 

2. Using Heat

As mentioned, the plumber’s putty is clay-like and quite soft. Therefore heat is quite important in its application. Before you apply the putty, you should ensure your hands are warm. 

You can warm your hands by simply rubbing them together for some time before applying the putty. 

What Makes The Plumber’s Putty Different From Other Sealants? 

The plumber’s putty is one of the most critical tools in the plumber’s arsenal. The tool is popular across the plumbing industry to perfectly seal leakages. 

However, the silicone caulk is popular today and performs the same functions as the plumber’s putty. The great thing about the putty is it’s easy to remove because it’s not adhesive. 

The tool also remains soft, and this makes it easy to remove. Even if it’s hardened, you can chip it away without a struggle. The silicone caulk is more effective; however, it’s a more permanent fixture. 

Therefore once applied, it is quite difficult to remove. The silicone caulk is also not dense like the putty. Being less dense makes it ineffective when it comes to filling significant gaps. 

You can use the silicone caulk on your sink or faucet, but removing it will be quite troubling. Therefore do not use the silicone caulk before knowing its consequences.

What Makes The Plumber’s Putty Bad For Pipes? 

The plumber’s putty is quite versatile; however, it is limited. Using putty on a plastic pipe is not a great idea. The putty is a petroleum-based product, and therefore it can break down the plastics’ chemical structure. 

The plastic material will certainly lose its durability after some time. The effect worsens when the plastic parts are under consistent tension and leaking. Therefore the best way of fixing the plastic pipes is by using silicone caulk.

How Soon Can You Use The Sink After Applying Plumber Putty?

People love the plumber putty because it is amazing and easy to use. After applying the plumber putty, you can immediately start using the sink or faucet. 

There is no waiting or drying time because the putty does not dry. It simply does its function of sealing the faucet, tap, and sink, and you can immediately use them after the application. 

Is It Possible To Use Plumber Putty Under Water

You cannot use putty for underwater applications. It’s because a plumber’s putty cannot form a bonding water-tight seal. 

The plumber’s putty has been mainly made for application on sinks, drains, and faucets. Their main function is to prevent water from seeping through.

Plumber’s Putty On Rubber Gasket 

The plumber’s putty is not recommended for sinks or drains with a rubber gasket. Plus, you should not apply putty if the flange is not metallic. 

The best option here is the silicone caulk. Always read the instructions and the directions before using plumbers putty on your drain assembly.

How To Use Plumber’s Putty

The plumber’s putty is a crucial and inexpensive material. Usually, it’s packaged and sold in small plastic tubs. 

To apply the plumber’s putty, you need first to shape it using your hand. Here are some of the steps to follow when applying the plumber’s putty. 

1. Create a putty rope  

Scoop a considerable ball of putty using your finger and roll it with your palms to create a rope. You can make a rope of any length, but its diameter should be slightly larger than the gap you want to fill.

2. Place The Putty Rope 

After creating a rope of your desired diameter and length, you can now place it on the part you want to seal. 

Placing it is quite simple; you can start from any point and work in a continuous loop. However, if you notice the rope is short, it’s best to start over and create a longer rope. 

3. Press It Into Place 

You need to press the rope and avoid deforming it gently, and it will prevent it from being loose when turning the part right side up. If you press the putty so flat in this stage, it will not seal perfectly. 

4. Install The Part

You need to install the part perfectly. The excess plumber’s putty will squeeze from the edges as you slowly tighten the part. It is good since it means you have used enough putty. 

You should continue tightening the parts until it’s perfect and wipe the excess putty with a piece of rag or finger. If the excess putty is still clean, you can put it in the tub for future use.

Conclusion

The plumber’s putty is a very crucial tool in plumbing. The simple tool comes with various great benefits, which is why plumbers love it. However, you need to know how to use it before purchasing. 

The putty is usually soft, and this makes it easy to handle. If the putty is hard or breaking, it means it is old and thus will not perform its functions well. The putty takes quite long to dry, and that’s between ten to fifteen years.
