The Difference Between Taping and Putty Knives

Taping knives and putty knives may appear similar, but they serve different purposes. While you can use them interchangeably, it's often best to use each for its intended task. Understanding the difference between the two can help you maximize their effectiveness.

Taping Knife:

- Also known as joint knives, taping knives have wide blades designed for spreading joint compound over seams.

- Available in various sizes, typically ranging from 6 to 12 inches. Smaller sizes, like the 6-inch joint knife, are ideal for tight areas.

- Used for applying mud, laying tape, and finishing drywall. Blades are typically made of carbon steel, stainless steel, or blue steel, with stainless steel being the most common.

Putty Knife:

- Putty knives come in different designs but generally have a flat-edged blade. They can be flat or chiseled.

- The flat-edged blade is versatile, serving as a scraper and spreader.

- Chiseled edge blades are angled, allowing the tip to press diagonally, useful for various tasks.

- Putty knives are stiffer than taping knives, making them ideal for scraping old paint, wallpaper, and spreading spackle.

- Smaller putty knives are suitable for tight corners, while wider ones are better for larger surfaces.

Intended Use:

- Use taping knives for spreading joint compound smoothly over drywall seams, ensuring a finished look without bumps or bubbles.

- Putty knives are ideal for scraping away old paint, wallpaper, and applying spackle. They can also be used for drywall compound in a similar manner, as spackle is thicker.
