Last year, I was advised at my hardware store to give a paint job to my house with a special paint, to protect the walls from severe rains allegedly forecasted for the season.
So I bought a few gallons of paint and
painted the outer walls, two hands of paint 21 days apart, because apparently that's what you should do with this paint, even though initial ads claimed one hand of paint would be 100% effective at avoiding fading of the color and crackling of the coating.
Turns out, just six months later, the paint starts to crack and the color has faded completely. I go ask for an explanation at the hardware store, and the clerk explains that even though the paint cracked and faded, It protected my walls from mold, and talks me into buying more paint to give a third hand of paint.
So I paint a third hand, and surely enough, six months later the paint has cracked again, and there's even traces of mold poking through the inner walls.
I went back to the clerk, furious, and complained about the paint. I got strongly rebuked, he went on a tirade saying I should trust the experts and that I'm a conspiracy theorist of some kind, all the customers in the store giving me the evil eye.
Turns out the paint has been ineffective because my neighbour, who's a rain-denier and an anti-paint, hasn't coated his outer walls with the same paint. Now the clerk has given me a booster paint plan, in which he'll have my walls painted every six months, but it seems I have to paint my kids' treehouse as well for the paint to be effective.
