In our opinion, the Krylon sealant is the best option for sealing your tempera paint and adding a layer of waterproofing to it. The spray is quick to act, easy to use, and very cheap considering how much of it you actually get.

It is applied via a spray system and you simply hold the sealant around six inches away from the surface that you have used your tempera paint on and then spray once the paint is dry. Try to get a nice even coat of the sealant onto your tempera paint and let it dry. Once the sealing agent has dried it will offer a protective, waterproof layer above your tempera paint.

There are a number of different Mod Podge formulas on the market these days but any of them should be able to get the job done with the red or yellow label Mod Podge usually being considered the best option. You will need a small bush to apply your Mod Podge on top of the tempera paint but the process is as easy as it sounds, dip the brush into the Mod Podge and then apply it to the tempera paint.
