## Plumbers Putty for Kitchen Sink: A Comprehensive Guide
### What is Plumbers Putty?
Plumbers putty, also known as glazing putty, is a pliable, oil-based sealant commonly used in plumbing applications. It consists of a mixture of linseed oil, calcium carbonate, and other ingredients that give it a sticky, putty-like texture.
### Purpose of Plumbers Putty in Kitchen Sinks
In kitchen sinks, plumbers putty serves two primary purposes:
– **Sealing Drain Assemblies:** Plumbers putty forms a watertight seal between the drain flange (or basket strainer) and the sink material, preventing water from leaking beneath the sink.
– **Mounting Kitchen Fixtures:** It can be used to secure fixtures such as garbage disposals, soap dispensers, and sprayers to the sink, ensuring a solid and stable connection.
### How Much Plumbers Putty to Use
The amount of plumbers putty required for a kitchen sink depends on various factors, including:
– **Size of the Drain Assembly:** Larger drain assemblies require more putty to ensure a complete seal.
– **Sink Material:** Different sink materials, such as porcelain, stainless steel, and composite, may require different amounts of putty for a secure fit.
– **Type of Fixture:** Garbage disposals and other fixtures vary in size and require appropriate amounts of putty to ensure stability.
As a general guideline, the following recommendations can be followed:
– **For Drain Assemblies:** Apply a 1/4 to 1/2 inch thick bead of putty around the rim of the drain flange. Use more putty for larger assemblies.
– **For Mounting Fixtures:** Apply a pea-sized dollop of putty to the base of the fixture and another to the mounting surface. Tighten the fixture securely.
### Applying Plumbers Putty
**Materials Required:**
– Plumbers putty
– Putty knife or spatula
– Clean cloth or sponge
**Steps:**
1. **Prepare the Surfaces:** Clean and dry the mating surfaces of the drain assembly or fixture and the sink. If the surfaces are excessively wet, the putty may not adhere properly.
2. **Form the Bead (for Drain Assemblies):** Roll out a 1/4 to 1/2 inch thick rope of putty and form it into a circular bead around the rim of the drain flange. Smooth the putty with a putty knife or your finger.
3. **Apply the Putty (for Fixtures):** Place a pea-sized dollop of putty on the base of the fixture and another on the mounting surface.
4. **Attach the Drain Assembly or Fixture:** Place the drain assembly into the sink hole or attach the fixture to the designated location. Tighten the assembly or fixture securely.
5. **Remove Excess Putty:** Use a clean cloth or sponge to wipe away any excess putty that may have squeezed out during installation.
### Tips for Using Plumbers Putty
– **Use Fresh Putty:** Avoid using old or hardened putty, as it may not adhere or seal effectively.
– **Knead the Putty:** Before applying, knead the putty until it becomes pliable and easy to work with.
– **Press Firmly:** Apply the putty firmly to ensure a tight seal and prevent water leaks.
– **Allow Curing Time:** Allow the putty to fully cure before using the sink to avoid disturbing the seal. Curing time typically takes around 4 hours.
### Conclusion
Plumbers putty is an essential material for ensuring a leak-proof and secure kitchen sink installation. By following the recommended amounts and proper application techniques, you can effectively seal drain assemblies and mount fixtures with confidence. Understanding the purpose and correct use of plumbers putty will help you maintain a functional and aesthetically pleasing kitchen sink.
