After getting your supplies, you may start the blending course of. Begin by including a small quantity of Bondo to your mixing container. Then, add slightly little bit of hardener and blend completely with the paddle. The consistency of the Bondo must be just like peanut butter—not too thick and never too skinny. As soon as you have reached the specified consistency, you may apply the Bondo to the broken space utilizing the putty knife.
Mixing Bondo is an easy course of, however there are some things you want to remember to get one of the best outcomes. First, be sure you’re utilizing the proper ratio of Bondo to hardener. The perfect ratio is 100 components Bondo to 2 components hardener. In the event you use an excessive amount of hardener, the Bondo will set too shortly and turn into troublesome to work with. Conversely, in case you use too little hardener, the Bondo won’t set correctly and will likely be weak and crumbly. Second, be sure you combine the Bondo completely. If the Bondo isn’t blended completely, it won’t have the identical energy and sturdiness as it will if it have been blended correctly.

Totally different ratios of hardener to resin are used for various functions. For normal Bondo repairs, a 50:50 combine is often used. Nonetheless, for purposes requiring a slower curing time or a stronger bond, a decrease share of hardener could also be used, whereas the next share of hardener will end in a quicker remedy time however a probably weaker bond.
| Hardener Ratio | Objective |
|---|---|
| 10:1 | Slower curing time, stronger bond |
| 20:1 | Commonplace Bondo repairs |
| 30:1 | Sooner curing time, weaker bond |
Along with the hardener-to-resin ratio, the particular kind of hardener and resin used also can have an effect on the ultimate properties of Bondo. For instance, high-strength Bondo merchandise usually use a extra aggressive hardener, leading to a quicker remedy time and the next bond energy. Conversely, customary Bondo merchandise are formulated with a much less aggressive hardener, offering a slower remedy time and a weaker bond energy.
Step 4: Checking the Consistency and Including Filler if Wanted
After getting added the hardener, it is essential to combine the Bondo completely. Begin by stirring slowly and regularly growing the velocity because the combination begins to thicken. Purpose for a consistency that resembles peanut butter – not too runny or thick.
