How Long Does It Take for Bondo to Cure?
I remember when I was first starting out with auto body repair, I was eager to get my hands on some Bondo and start filling in dents and scratches. But I quickly learned that Bondo doesn’t just dry instantly—it has to cure. And depending on the type of Bondo you’re using, the curing time can vary.
In this article, we’ll take a closer look at the curing process of Bondo, including the different types of Bondo and how long each type takes to cure. We’ll also provide some tips for speeding up the curing process and answer some frequently asked questions about Bondo.
What Is Bondo?
Bondo is a brand name for a type of auto body filler. It is a two-part epoxy that is used to fill in dents, scratches, and other imperfections in metal surfaces. Bondo is made from a resin and a hardener. When the two parts are mixed together, they create a chemical reaction that causes the Bondo to harden.
The Curing Process
The curing process of Bondo is a two-step process. In the first step, the resin and hardener react to form a solid. This process is called polymerization. In the second step, the solid polymer undergoes a cross-linking process, which makes it stronger and more durable.
The curing time of Bondo can vary depending on the type of Bondo you’re using. There are two main types of Bondo: regular Bondo and high-build Bondo. Regular Bondo is a general-purpose filler that is used for small to medium-sized repairs. High-build Bondo is a thicker filler that is used for larger repairs, such as filling in large dents.
The curing time for regular Bondo is typically 30 to 60 minutes. The curing time for high-build Bondo is typically 90 to 120 minutes. However, the curing time can be affected by a number of factors, such as the temperature and humidity.
Tips for Speeding Up the Curing Process
There are a few things you can do to speed up the curing process of Bondo. First, make sure that you mix the resin and hardener thoroughly. If the two parts are not mixed properly, the Bondo will not cure properly.
Second, apply the Bondo to the repair area in thin layers. This will help the Bondo to cure more quickly and evenly. Third, place the repaired area in a warm, dry place. This will help the Bondo to cure more quickly.
