Frequently Asked Questions

Does spray paint stick to Hydro Flasks?

Spray paint can adhere well to Hydro Flasks if the surface is properly prepped and primed first. Scuffing the surface before painting gives the paint something to grip. Using primer spray provides an extra bonding layer.

Is it safe to spray paint a Hydro Flask?

It’s generally safe if done properly in a well-ventilated area while wearing a respirator mask. Be sure to cover any parts you don’t want painted. Follow the usage directions on the spray paint cans.

How long does the new paint last?

The paint may eventually scratch, chip or fade over time with regular use. Properly prepping the surface and using a clear sealer helps extend the life. Avoiding scrapes and drops helps prevent chips.

Can I just use a paint brush instead of spray paint?

You can use acrylic craft paint with a brush, but it likely won’t go on as evenly as spray paint. The hand-brushed finish may have visible brush strokes. Spray paint is best for full, smooth coverage.

Is there paint made specifically for Hydro Flasks?

There are a few specialty spray paints like Plasti Dip that work well on metal and plastic. But many standard primer, color and clear coat spray paints sold at hardware stores will also work if applied properly.


Repainting your Hydro Flask can give it a brand new look and allow you to customize the color. With proper preparation, materials, and technique, spray painting your Hydro Flask is certainly doable. Just be sure to use caution and proper protective gear when spray painting. Consider the pros and cons first, and explore other options like skins, decals and engravings if you decide repainting isn’t for you. But if you want to change up the color of your Hydro Flask, go ahead and give repainting a try!
