What is the Difference Between a 1k and 2k Poly for Cabinet Refinishing?

Updated: Jul 5, 2023

What You Need to Know"Polyurethane (PU) wood coatings have become a popular solution for protecting and enhancing the look of wooden surfaces. Waterborne 1k and 2k PU coatings are standard options, each offering unique benefits and drawbacks. In this blog post, we'll take a closer look at the differences between waterborne 1k and 2k PU coatings so that you can make an informed decision for your next project.




Waterborne 1k PU Coating: Waterborne 1k PU coatings are single-component, water-based products that are easy to use and dry quickly. They provide a protective and decorative finish, making them an ideal solution for indoor surfaces not subjected to heavy wear and tear. With low fumes and a more environmentally friendly profile, waterborne 1k PU coatings are an excellent choice for anyone looking for an easy to apply solution.


Waterborne 2k PU Coating: If you're looking for a more durable and long-lasting finish, waterborne 2k PU coatings may be the right choice. These two-component products consist of a resin and hardener, providing stronger and more durable protection than 1k coatings. This does not come without its own set of challenges. Once you add a harder to the resin system, you will have a short window to apply the product before it hardens. This requires greater attention to detail when cleaning equipment to endure optimal performance on your next job.


Which One is Right for Your Project?

Choosing between waterborne 1k and 2k PU coatings will depend on your needs and requirements. If you're looking for a fast and easy solution for a wooden surface not subject to heavy wear and tear, a waterborne 1k PU coating may be the way to go. However, if you're looking for a long-lasting, high-quality finish that will provide maximum protection, a waterborne 2k PU coating is probably the better option.


In conclusion, both waterborne 1k and 2k PU coatings offer unique benefits and drawbacks, and the best choice will depend on the specific requirements of your project. Whether you're looking for a quick and simple solution or a durable and long-lasting finish, there's a waterborne PU coating to meet your needs.
