Hope someone has a suggestion for us !

A couple of years ago we had some water infiltration problems. We solved them by installing a french drain around the house. Since all the foundation walls were exposed and we didn't have insulation in the basement, -20C in the winter, we decided to spray it with polyurethane foam (outside foundation walls).

Our house is very warm in the winter which is really nice, but outside it looks horrible. We did paint it in order to protect it.

Is there anything we can put on it that would adhere or look better ??
One wall is fully exposed and the three others have about 3 ft exposed.

Suggestions ?

Thank you.
