How to Hydro Dip Rounded Parts

Hydro dipping allows you to apply unique graphics to almost any three-dimensional object. This entails objects of any shape, be it round, oval, square, or cubed. Dipping helmets, firearms, and gaming controllers uses a different technique from that used when dipping round objects. As you might have noticed in your quest to understand hydro dripping, this technique can be used for three-dimensional and other shapes. The key is to make sure the surface texture can absorb the ink printed on the film.

We recommend you scrutinize the sanding process for round objects for an even surface. More complex shapes require careful sandblasting for a final satisfying look. Below we explain the steps and things you should know when dipping round objects.


Keep in mind the item you’re hydro dipping will be fully submerged underwater. All electronic items should be stripped. The only remains should be the shell where the graphics will be imprinted. A round object’s preparation stage requires that you analyze the surface, observe safety features, and sand if necessary. If the item has any screws on it, remove them for uniformity of the film upon dipping. Make sure you paint your round object with the correct base coat for the film to look correct after the dip.

Dipping the object while having other attachments on it can alter the look and the symmetry of the pattern. For a professional look, we advise you to first plan how you will roll it. Rolling a round object is an improvised way to limit the errors you might experience when dipping the object the same way you would dip a flat item.

Cutting the Film

The size of the object you’re dipping determines the amount of film you’ll cut. Cutting a film slightly larger than your object’s size avoids waste and reduces the margin of error by preventing the emergence of bubbles. The film’s size should also be in line with that of the tub for convenience when dipping. Bearing the fact that this is a round object, the film’s size should give you the space to roll it. Tape the film to control it from rolling back in the initial shape it was packaged in.

Laying the Film on the Water

Make sure the tub dividers are pulled up far enough to give room for laying the film. Determine the side that faces down on the water by dipping your fingers into the water and touching a corner of the film. Hold the film for a few seconds, and the side that sticks to your finger faces down on the water.

Lay the film from corner to corner to avoid trapping air. Tighten the dividers to control the position of the film and prepare to spray the activator. Gently spray the activator evenly across the film to create a sleek and glassed out look over the entire film.


Gently dip your round object at an angle, slowly coming down at about half the object. Slowly turn the object to the remaining side and wrap it all the way around. The result will be a uniform pattern that goes all around the part. The trick is making sure the end of the pattern faces the backside of the object.

This is just but an insight on how to hydro dip a round object. Be sure to thoroughly consider the design of the object before dipping for a one of a kind look.
