FAQs

Do I really need a heat gun, or can I just use a hairdryer to soften the old putty?

A heat gun like the Genesis GHG1500A is highly recommended because it reaches much higher temperatures than a hairdryer, which is crucial for effectively softening hardened plumber's putty. A hairdryer may not generate enough heat to make the putty pliable enough for easy removal. Using the right tool will save you time and effort.

What are the most important safety precautions I need to take when using a heat gun and mineral spirits?

When using a heat gun, always wear heat-resistant gloves and eye protection to prevent burns and protect your eyes. For mineral spirits, ensure adequate ventilation by opening windows or using a fan to disperse fumes, and wear chemical-resistant gloves. Always keep a fire extinguisher nearby when working with heat and flammable solvents.

How long should a beginner expect this project to take, and what's the typical cost?

For a beginner, removing old, hardened plumber's putty from a single fixture can typically take 1-2 hours, depending on how stubborn the putty is and the size of the area. The cost is minimal if you already own a putty knife; otherwise, the required tools and materials like the heat gun, mineral spirits, and rags can range from $50-$100, providing you with supplies for future projects.

What if the putty still won't come off easily even after heating and scraping?

If the putty remains stubborn, re-apply heat from your Genesis heat gun for a longer duration, focusing on smaller sections at a time to ensure thorough softening. You can also try different angles with your putty knife or gently use a plastic scraper if the surface is delicate. Patience and multiple applications of heat and solvent may be necessary.
