I found a picture of a Fire place painted in a whitewashed style. I like it so much I want to do it to my fireplace but am unsure of how to do this. I asked at a painting store and they said it was a destressing method, where you paint on the paint and wipe off until you have the look you want. They were unsure of the formula if any for the paint but said I should use an acrylic latex paint. I may they said want to dilute it with water, but to practice on old brick. Do you have any suggestions. They did not know for sure so I am nervous, I need help from one who is sure.

 

If what you want is to see the brick but make it look old (time worn) this maybe what you want:
Fill a squirt bottle (16oz. or larger) with any flat latex paint thinned to a ratio of 14oz. of paint to 2oz. of water. Spray a small area of the fireplace with paint and pat it onto the brick with a very wet, warm sponge. Let it dry thoriughly. Do this to the entire fireplace.
Hope this helps.
