5-foot walls promote airflow and allow the horses to see over them. The roofs are composite shingles, which are much quieter than metal in the rain. The floors are rubber mats that are spiked into the ground, so the horses avoid ingesting any sand when eating
Spray paint: rubber door mat with a primer (any light color), base coat with black (allow dry time between coats). Use two coats of the Matte Heirloom White, allow a few days airing time outside. Use 120 grit sand paper on a small hand sander, sand to distress/aged feel.
