As an artist and a painter, there is nothing new here that I didn't already know or understand.
I had hoped he would zoom in more and identify the bonding precess of the latex particles.

Different types of paints bond differently. (oil, water colours, latex, acrylic, gouache, egg)

Acrylic is quite different than most paints as once the medium evaporates and the pigment binds, it cannot be redissolved.Once the barrier between the pigment particles is removed, the pigments bond to one another to become a larger particle, on and on until the paint is dry and the particles form one large piece of solid plastic - never again to be separated.

Water Colours have no binders in them at all so once the water evaporates, the pigment just drys on the paper. Re-introducing water again will lift the pigment again as the process starts over. (minus pigment particles that get caught in the tooth of the paper.)

Oil paints stick together in linseed oil and are bonded by the linseed. It causes a strong bond but oil paint can be dissolved again using the right solvents. A varnish is used not to adhere (or fix) the pigment but to both hide linseed imperfections and to protect the paint surface from scratches.

Latex paint is a rubber (unlike plastic acrylics) and the process for the drying is different again. Anyone ever watch a foam rubber pour?

With all the differences, this video gives a rather slim and elementary vision of what is going on. It's more a document of evaporation more than anything as we watch the water dissipate and leave the pigment behind to stack on itself.

I would really like to have seen the actual pigments bonding with each other. I would also have liked to have seen different paints in comparison.
