"I accidentally posted the following under S-W Duration paint. It belongs under S-W SuperPaint
Less than two years after using this paint, there is mold and mildew on every trim surface. Turns out this 25 year warranty exterior trim paint didn't have a fungicide in it and no one at the store advised adding it. Our house was completed resided, including all new trim and new Anderson windows all of which started growing mold and mildew within a year of application and finger joints on new sills are swelling. I took the remaining paint back to the store and was promised a phone call that same day to set up an inspection. Had to place a follow-up call and finally received a visit a week later.
S-W has offered nothing but advice to pressure wash with bleach annually. A 25-year warranty is only as good as the company issuing it. It remains to be seen whether S-W stands behind their product and warranty."
