In an imaginary scenario, I paint with acrylics, let's say on canvas board or similar.
I don't use any fancy techniques, like impasto. Just the "normal" amount of paint and commonly used acrylic mediums.
I would like to know, whether I should be concerned about what these materials do when they get into the drain pipes (in the kitchen sink, or in the bathroom), when I wash out my brushes, and maybe some jars.
- I know that as soon as acrylic painting materials get wet and then get a chance to dry, they end up forming a solid substance.
- As far as I know / can imagine, drain pipes are not always soaked 100% in water, rather they have patches that get non-submerged from time to time.
Is it possible that acrylics materials could form dried-on layers within the drain pipes? That they could build up with time, decreasing the cross-section available for water flow?
Is this a valid concern? If yes, what could I do to mitigate it?
