What You'll Learn
Mixing paint, activator and reducer by weight
Mixing paint, activator, and reducer by weight can be a tricky process, and it is important to get it right to avoid paint failure. The key challenge is that each toner has a different weight, so the ratio of hardener to reducer to paint will vary depending on the colour you are using.
To start, you will need a digital scale that can measure to at least tenths of an ounce. Put your container on the scale and zero it out. Then, add your paint, activator, and reducer according to the recommended ratio for your specific paint. For example, a standard mixing ratio for single-stage paints is 8/1/1 – that is, for every 8 parts paint, add 1 part thinner/reducer and 1 part hardener/activator.
It is important to use a container with straight sides and a flat bottom, such as a metal paint can, to ensure accurate measurements. Mixing cups tend to have tapered sides, which can result in inaccurate measurements and an uneven mix.
Some paint companies use computerized digital scales, which can help manage materials and correct any over-pouring of toner. However, these systems are expensive.
It is always critical to be accurate when mixing modern paints, as the amount of reducer and activator is crucial to the final product. Improper mixing can result in paint failure.

Using a gram scale to measure
While I could not find information specific to P-6100 paint, I did find general information about mixing paint with an activator using a gram scale.
Mixing paint with an activator requires precision, and digital scales are often used to ensure accuracy. It is important to note that volume and weight are two separate measurements, and using the same ratio for volume as for weight will not yield the correct mixture.
To mix paint with an activator using a gram scale, you will need to determine the correct ratio of paint to activator. This ratio may depend on the type of paint you are using and the ambient temperature. For example, if you are using urethane paint, the type of activator (fast, medium, or slow) will depend on the ambient temperature.
Once you have determined the correct ratio, you can use your gram scale to measure out the paint and activator. Place your container on the scale and zero it out. Then, add the paint to the container until you reach the desired weight. Repeat this process for the activator, adding it to the container until you achieve the correct weight ratio.
For example, if you are mixing SPI Epoxy primer and activator, you can weigh out half a quart of primer on a stick, record that weight, and then add the activator until you reach the desired total weight. This will give you a weight formula that you can use for future mixtures.
It is important to note that mixing paint and activator in a cylinder is crucial, as any other container with a varying width will result in an inaccurate mixture. Additionally, always stir the paint and activator thoroughly after combining them to ensure they are properly mixed.

Mix ratio of hardener to reducer to paint
When mixing paint, hardener, and reducer, it is important to follow the correct mix ratio to ensure the best results. The mix ratio will depend on the type of paint being used and the specific products involved.
For example, modern two-pack systems and solvent-based metallic colours are typically mixed at a ratio of 2:1 with a compatible hardener or thinner. This means that for every two parts of paint, you would add one part hardener. Water-based colours, on the other hand, usually require a different ratio, often mixed at a ratio of 10:1 with a compatible water-based thinner.
It is important to always refer to the technical data sheet supplied with the automotive paint to determine the correct mix ratio. This information can usually be found on the paint mixing stick or cup, which will have markings indicating the correct ratio. The type of paint will affect the ratio, so it is important to use the correct products and follow the manufacturer's instructions.
In general, the mixing process involves adding the paint to a mixing pot or cup, followed by the hardener and reducer in the correct ratios. It is important to allow the materials to settle for a few seconds before stirring them together. Once mixed, the product can be added to a spray gun for application.
It is worth noting that some sources suggest that mixing by weight can be challenging due to variations in the weight of different toners. Instead, it may be more accurate to mix by volume, ensuring that the ratios of paint, hardener, and reducer are consistent. This can be done by using a measuring stick or cup with marked ratios or by measuring the volume of each component in ounces or grams.

Mix by volume, not weight
When mixing paint P-6100 with an activator, it is recommended to mix by volume and not weight. This is because each toner has a different weight, so the ratio of hardener to reducer to paint will vary depending on the colour and weight of the toners used. For example, a mix of light-weight toners will require a different ratio than a mix of heavy-weight toners.
Mixing by volume can be done by pouring each product into a container until it reaches a certain level, and then mixing them all together. This method may be less accurate than mixing by weight, but it is still effective and results in less waste and cleanup. It is important to note that the standard mix ratio for clear coats is typically 4:1:1, with 4 parts being clear, 1 part being the reducer, and 1 part being the hardener or activator.
Additionally, it is worth mentioning that the pot life of the mixture should be considered. Pot life refers to the amount of time the mixture remains usable before it goes bad and starts to harden. Clear coats mixed with an activator and reducer typically have a shorter pot life than base coats, which do not require an activator.
Furthermore, the temperature during the application process is crucial. While warming the air can help the paint spray more evenly and evaporate correctly, it can also affect the crosslinking of the paint as it hits the cold metal. This can impact the curing process, which is activated by the hardener or activator.
In conclusion, when mixing paint P-6100 with an activator, it is recommended to mix by volume and not weight due to the varying weights of toners and the potential for inaccurate measurements when using weight as a metric. By mixing by volume and following the standard mix ratios, you can achieve effective results while also minimising waste and cleanup.

Pot life and usability
When mixing paint, activator, and reducer, it is important to consider the pot life and usability of the mixture. Pot life refers to the amount of time the mixture remains usable before it goes bad and starts to harden. Understanding the pot life is crucial to ensure that the mixture is used efficiently and effectively within its usable timeframe.
For clear coats, it is necessary to mix them with an activator and a reducer. The standard mix ratio is 4:1:1, with four parts being clear, one part reducer, and one part activator (also known as a hardener). This ratio can vary depending on the specific products and their weights, as each toner has a different weight. Therefore, it is important to follow the recommended mix ratio provided by the manufacturer.
Mixing by volume is generally recommended, as it is more accurate than mixing by weight. However, when mixing by weight, it is crucial to use a mixing bank system, where the computer already knows the weights of the products and compensates on the scale. This ensures an accurate mix ratio. Additionally, using a digital scale that reads to tenths of an ounce can help with precise measurements.
The pot life of the mixture can vary depending on various factors, including the temperature. For example, paint goes dormant below a certain temperature, affecting its usability. Additionally, the crosslinking of the paint may be impacted if the temperature of the substrate or part is too low, even if the ambient temperature is suitable. Therefore, it is important to consider the temperature during the mixing and application process.
It is also important to note that activators and hardeners from different brands may not be compatible with the paint. Therefore, it is generally recommended to use the same brand of paint and activator to ensure compatibility and achieve the desired results.
