Hydro Dipping Tanks: Tips and Tricks for Successful Dipping


Introduction to Hydro Dipping Tanks

Hydro dipping, also known as water transfer printing, is a fascinating technique used to apply intricate and decorative designs to various three-dimensional objects. It involves submerging the object in a tank filled with water and transferring a specialized film onto its surface. The film adheres to the object, resulting in a stunning and durable pattern. Whether you are a hobbyist or a professional, having a reliable hydro dipping tank is essential for achieving successful results. In this article, we will explore some tips and tricks to help you make the most out of your hydro dipping experience.

Tips for Setting Up Your Hydro Dipping Tank

Properly setting up your hydro dipping tank is crucial to ensure smooth and consistent results. Here are some tips to help you get started:

Choose the Right Tank Size

The size of the tank you choose will depend on the objects you plan to dip. If you primarily work on smaller items like phone cases or tools, a small-to-medium-sized tank will suffice. However, if you often dip larger objects such as car parts or furniture, investing in a larger tank is recommended. Ensure that the tank's dimensions accommodate the size of the objects you typically work with.

Consider Tank Material

Hydro dipping tanks are commonly made from either stainless steel or plastic. Stainless steel tanks are more durable and resistant to corrosion, making them ideal for long-term use. On the other hand, plastic tanks are more affordable and lighter, making them easier to maneuver. Consider your budget and long-term goals when choosing the material for your tank.

Ensure Proper Ventilation

Working with hydro dipping tanks involves the use of chemicals and paints, which can emit fumes. To ensure a safe working environment, it is important to have proper ventilation in your workspace. Install an exhaust fan or work in an area with good air circulation. This will help dissipate any potentially harmful fumes and keep you comfortable during the dipping process.

Substrates and Preparing Objects for Dipping

The type of substrate you choose plays a significant role in the success of hydro dipping. While many materials can be hydro dipped, some yield better results than others. Commonly used substrates include plastic, metal, wood, and ceramics. Ensure that the object you plan to dip is clean, free from dust, grease, or any other contaminants. Proper prepping is crucial as it allows the film to adhere smoothly to the object's surface.

Cleaning and Priming the Object

Before dipping, thoroughly clean the object using a mild detergent or degreaser to remove any oils or residues. This step ensures maximum adhesion of the film. Once the object is clean, consider applying a primer. Priming helps create a smooth and uniform surface, enabling the film to bond more effectively. Use a primer that is compatible with the material of your object, and allow it to dry completely before proceeding to the dipping process.

Introducing the Dipping Process

Now that your hydro dipping tank is set up, and your objects are prepped, it's time to dive into the exciting dipping process. Follow these tips for a successful and visually appealing outcome:

Activating the Film

Hydro dipping films come with a special water-soluble layer called the activator. This layer dissolves and activates the ink, allowing it to adhere to the object's surface. Carefully spray the activator onto the film's surface, ensuring that it covers the entire area. The activator should be applied evenly to avoid any patchy or inconsistent patterns.

Timing is Key

Once the activator has been applied, carefully submerge the object into the water tank. The timing of this step is crucial. If you leave the object in the water for too long, the film may disintegrate or become blurry. Conversely, if you remove the object too quickly, the pattern may not fully transfer onto the surface. Follow the instructions provided by the film manufacturer for the optimal dipping time.

Dipping Techniques

There are several techniques you can use while dipping to achieve different effects. Here are a few popular ones:

Immersion Dipping: This is the most common technique, where the object is fully immersed in the water tank, allowing the film to wrap around its entire surface.

Partial Dipping: In this technique, only a portion of the object is dipped into the water, leaving some areas exposed. This creates a unique two-tone or contrasting effect.

Pattern Manipulation: By manipulating the film's surface with tools like combs or rakes, you can create custom patterns and designs. Experiment with different tools and techniques to achieve the desired effect.

Rinsing and Drying

After the dipping process is complete, carefully remove the object from the tank, ensuring not to smudge or disrupt the transferred pattern. Rinse the object with clean water to remove any excess film or activator residue. Use a gentle stream of water to avoid damaging the pattern. Once rinsed, allow the object to dry completely before handling or applying any additional protective coatings.

Caring for Your Hydro Dipped Objects

To ensure the longevity of your hydro dipped objects, it's important to properly care for them. Here are some tips to keep in mind:

Avoid Abrasive Cleaning

Avoid using abrasive cleaners or scrubbing brushes on hydro dipped objects, as they can damage the pattern. Instead, use a soft cloth or sponge to clean the surface gently. Mild dish soap mixed with warm water is usually sufficient for cleaning.

Protect with Clear Coating

Applying a clear protective coating over the hydro dipped surface can help enhance its durability and prevent fading or chipping. Select a clear coat that is compatible with the material of your object. Follow the manufacturer's instructions for proper application and drying times.


Hydro dipping tanks provide a creative and versatile method for adding unique designs to various objects. By following the tips and tricks outlined in this article, you can set up your tank effectively, prepare your objects correctly, and achieve successful dipping results. Experiment with different techniques, substrates, and patterns to unlock your creative potential and produce stunning hydro dipped creations. Remember to prioritize safety, ventilation, and proper care to ensure a rewarding and enjoyable hydro dipping experience.
