Ok, I'm not the nodes master and I need to add a kind of slight foam (using a bump gradient) to a liquid created with the dielectric node but I don't know how to mix both shaders

Any help, please?

You can use f.e. TrueArt's Node Library > Tools > Flatten Material and then plug them to Tools > Mixer.

You can blend it with a material mixer directly but you'll get weird art effects. So what sensei said is a good option.
You could also render 3 layers, one with foam, one dielectric and a matte pass which could be controlled by a gradient or a weightmap.

Thanks to both

Because I had to do it inmediately I had to improvise so finally i did something similar what 3DGFX said but using a forced bump to make the foam appears through the matte but I see that the way "Magic" Sensei said works amazingly :)
