Rewind to when John is painting the bedroom…
“Hmm, maybe I can save some time and money by not priming. That’s an hour or so in time and no money spent on primer,” John mutters to himself. “Mmm but I do want a nice looking room. Fine, I won’t skip it.”
John primes the wall the same way he will be painting it.
A few months later…
John walks into his bedroom to grab the book he is reading. As he’s looking for it he thinks he sees something coming through the paint on his wall. He examines it closely. It’s just a smudge, so he doesn’t have to look up how to clean wall paint. He quickly rubs the smudge off.
John looks around the room for any other signs of wall paint damage. Nothing. Looks like priming before painting is a good idea after all.
He finds his book and goes back to the living room where his spouse is waiting, book in hand.
