I am very lucky to have my studio in the backyard. The previous owners of our house had used the room as storage. It had a big sliding glass door that did not lock. We bought a French door set at Home Depot that has served me well and made the space more charming.
Unfortunately the muntins that divide the window are made of a plastic and have yellowed over time with the sun exposure. They were starting to bug me against the white of the doors (which are a vinyl door).
I decided to paint the muntins. I was told I could use a bonder to make the paint adhere better, but decided to see how it wears without that step. I can always repaint if it does not hold up. I used two of the little sample jars of Benjamin Moore Petunia Pink.
I like the pale pop of color and I think my concrete friends that guard the door are enamoured with the new look as well.
