I am about to repaint a porch floor that begins inside a glass-enclosed sunporch and extends to form a small ledge on the outside of the house.
Around 15 years ago I painted it with marine paint, and it seemed to hold up well.
Now, I'm told marine paint tends to get hairline cracks, although I haven't observed this.
What's the best type of paint to use in a situation like this? There is fairly heavy traffic on this floor.
