Can I mix acrylic paint with latex paint?
There actually is no difference between latex and acrylic paints because there is no latex in latex paints. Let me explain. All water based paints today are referred to as "latex", even though there is absolutely no latex rubber in the formula. ... Better quality paints have more acrylic resins than vinyl.

The acrylic paint for walls simply are thicker with more teeny acrylic beads that bind together when the water evaporates. THey pull together and tighten creating a coated surface of plastic polymer. The liquids in the paint may have some additives to strengthen and thicken this process. The thinner the paint (cheaper) means the less polymer beads the paint has in it.  Thus making the issue of multiple coats to fill in the areas that the beads were spread apart. Pigments are the colors added to the medium (polymers &amp; Liquid). Curing in the case of Acrylics is simply a drying process that tightens and pulls the polymer beads together. No chemical change is needed other than evaporation. Its not oil based.
