After getting your supplies, you’ll be able to start the blending course of. Begin by including a small quantity of Bondo to your mixing container. Then, add somewhat little bit of hardener and blend completely with the paddle. The consistency of the Bondo needs to be just like peanut butter—not too thick and never too skinny. As soon as you have reached the specified consistency, you’ll be able to 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 bear in mind to get one of the best outcomes. First, ensure you’re utilizing the precise ratio of Bondo to hardener. The perfect ratio is 100 elements Bondo to 2 elements hardener. If you happen to use an excessive amount of hardener, the Bondo will set too shortly and turn out to be troublesome to work with. Conversely, if you happen to use too little hardener, the Bondo won’t set correctly and might be weak and crumbly. Second, ensure you combine the Bondo completely. If the Bondo isn’t combined completely, it won’t have the identical energy and sturdiness as it could if it have been combined correctly. Lastly, ensure you apply the Bondo to the broken space instantly after mixing it. The Bondo will start to set inside minutes, so it is advisable work shortly to get it into place.
Introduction: Getting ready for the Mixing Course of
Correct preparation is essential for profitable Bondo mixing. Collect all crucial supplies earlier than beginning:
- Bondo physique filler. The primary element, out there in varied formulations for particular purposes.
- Hardener. A chemical catalyst that promotes Bondo’s hardening course of. Sometimes is available in small tubes or bottles.
- Mixing paddle or spatula. A flat, versatile instrument for stirring and making use of Bondo.
- Mixing board or paper. A clear, disposable floor for mixing Bondo.

Selecting the Proper Hardener-to-Bondo Ratio
The ratio of hardener to Bondo is essential for correct curing. An excessive amount of hardener could cause a fast, brittle set, whereas too little may end up in a weak, unfinished remedy.
Use the next guideline:
| Bondo Quantity | Hardener Quantity |
|---|---|
| 1 tablespoon (15 ml) | 1/4 to 1/2 teaspoon (1.25 to 2.5 ml) |
| 1 cup (240 ml) | 2 to 4 tablespoons (20 to 40 ml) |
Step 1: Choosing the Proper Hardener and Resin
Step one in mixing Bondo is to decide on the suitable hardener and resin. The hardener serves because the catalyst and initiates the chemical response that causes Bondo to remedy. Totally different ratios of hardener to resin are used for various functions. For traditional Bondo repairs, a 50:50 combine is often used. Nevertheless, for purposes requiring a slower curing time or a stronger bond, a decrease proportion of hardener could also be used, whereas a better proportion of hardener will end in a sooner remedy time however a doubtlessly weaker bond.
| Hardener Ratio | Function |
|---|---|
| 10:1 | Slower curing time, stronger bond |
| 20:1 | Normal Bondo repairs |
| 30:1 | Sooner curing time, weaker bond |
Along with the hardener-to-resin ratio, the precise sort of hardener and resin used also can have an effect on the ultimate properties of Bondo. For instance, high-strength Bondo merchandise sometimes use a extra aggressive hardener, leading to a sooner remedy time and a better bond energy. Conversely, normal 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 steadily rising the velocity because the combination begins to thicken. Goal for a consistency that resembles peanut butter – not too runny or thick.
Checking the Consistency
To check the consistency, dip a putty knife or popsicle stick into the combination. If the Bondo does not stick or drip off the instrument, it is prepared to make use of. Nevertheless, if it is too runny, it is advisable add extra hardener.
