How to Remove Old, Hardened Plumber's Putty · Step 2 of 6
In this video
Once the putty has fully cured and is hard to the touch, sand the repaired areas. Use a medium-grit sandpaper (120-180 grit is recommended) on a sanding pad. Sand down the overfilled putty until it is perfectly flush and smooth with the surrounding tub surface. The goal is to remove all excess material, leaving only the putty that is filling the original chip.
Goal: Create a smooth, level surface
- Feel the surface with your fingers to check for smoothness. It should be indistinguishable from the surrounding tub.

FAQs
How long does it typically take to remove old, hardened plumber's putty, and how difficult is this project for a beginner?
This is a beginner-friendly project, but patience is key. For a single fixture, expect to spend anywhere from 30 minutes to a few hours, depending on how much putty is present and how hard it has become. The most time-consuming part is often patiently softening very stubborn areas.
What essential safety precautions should I take, especially when using heat guns and chemical solvents?
Always ensure excellent ventilation in your workspace to disperse fumes from solvents like acetone. Wear appropriate personal protective equipment, including safety glasses to protect your eyes and chemical-resistant gloves to protect your skin. Be extremely cautious with heat guns to prevent burns and avoid damaging surrounding materials.
Can I use a regular hairdryer instead of a heat gun to soften the hardened plumber's putty?
A regular hairdryer (like the Aoibox HDDB1448) might work for very thin or moderately old putty. However, for truly hardened or thick plumber's putty, a dedicated heat gun (such as the Genesis GHG1500A or Master Appliance VT-751D) is significantly more effective, providing the higher, concentrated heat needed to soften it thoroughly and efficiently.
The putty is extremely hard and won't scrape off easily even after heating. What should I do?
If the putty remains stubborn, reapply heat more intensely or for a longer duration directly onto the hardened areas, allowing the heat to penetrate deeper. After heating, let the area cool slightly before applying solvents like Goo Gone Pro-Power (2180A) or Acetone (Klean-Strip CAC18) and allow them sufficient time to soak in before attempting to scrape again.
