The terms "latex" and "water-based" refer to a single type of water-based paint products, including primer and paint. This means that the base of latex paint or primer is water-soluble. In addition to water-based primer, there are oil- and shellac-based primers, both of which have bases that do not dissolve in water.
Then, is latex primer oil based?
Oil-based primers should not be used on masonry. Latex primers are water-based and ideal for prepping unfinished drywall for painting. They are more flexible and fast drying, and are less brittle than oil-based primers, making them less susceptible to peeling and cracking.
Also asked, is latex paint water based?
As opposed to oil-based paints, water-based paints (sometimes referred to as “latex paints” or “acrylic paints“) do not use solvents; the carrier for the pigment is primarily water. Latex paints also have a minimal odor and release significantly fewer VOCs during the drying process.
The major virgin latex paint constituents are resins (binder), titanium dioxide (pigment), limestone (extender), and water (thinner), which are mixed together until they form an emulsion.
