I am about to repaint a brick home that was painted in 2001. The paint has faded but held up remarkably well without chipping. How to I determine if the previous paint was oil based or acrylic?
Most likely it was an acrylic. There is a way to find out. I wrote an article about <a href="https://www.house-painting-info.com/kind-of-paint.html">how to figure out if your paint is acrylic (water based) or alkyd (oil based)</a>.
