Can the black aluminum balusters be painted? White would look better with our house.

Bev, The black aluminum balusters can technically be painted, but doing so would void the manufacturer’s warranty. Deckorators balusters come with a factory-applied finish, and altering that finish is considered a modification. If keeping the warranty intact is important, we recommend choosing balusters that are already available in the color you prefer. - Your Deckorators Team
