What’s your favorite way of applying putty? Do you use your hands or some specialized tools? However, you might apply it, scraping off the excessive materials properly is what leaves a smooth surface on your wood filler. The best tool for that job is a putty knife.

But before buying them, you need to learn some important factors about these knives. Below, find out how to choose the putty knife best-suited for your work and the details of some best-reviewed knives.

Putty Knife vs Scraper vs Taping Knife

Very often, people think of putty knives and scrapers as being the same tool. They also look very similar and often it gets hard to distinguish their application.

But in reality, they are different and their purposes also differ. Here, learn what is a putty knife used for and what tool to use for what purpose.

There are some tasks where you can use putty knives or scrapers as substitutes for each other. But if you are a perfectionist, your toolbox does require a putty knife. You can both scrape and apply plasters and other materials with this tool.

Putty knives are multi-purpose tools. They can be used for almost every task that you would have done with scrapers. Alongside, they can be used for other works such as wood filler application, smoothing dry-wall materials, scraping paints, etc. These knives come in versatile designs, with different edge shapes, handles, and materials. So a good-quality putty knife is a must-have for your toolbox.

Scrapers or paint scrapers, on the other hand, are old-fashioned tools but there are still some great uses for them. They are used for taking the paint off of something. They can also be used for removing excessive materials and smoothing off surfaces, but using scrapers require a whole lot of muscle energy.

Taping knives usually have a much wider blade and they cover a large area at one go. These are used for spreading compounds, usually on drywalls.

How to Choose the Perfect Putty Knife to Apply Wood Filler or Other Renovation Needs

Various kinds of putty knives differ in shapes and sizes. Choosing the right one takes much more than just looking at the brand name. Below, learn the factors that you need to know to choose the best putty knife.

Blade Material:

There are different kinds of blades- such as steel, plastic, etc. Steel blades are naturally more sturdy than other blades and they last longer. Plastic blades, on the other hand, are suitable for short-term projects.

Blade shape:

The blade shape depends on the application of the putty knife. Flat-edged blades are used for removing putty, whilst V or U-shaped ones are used for applying putty.
