Agricultural silage covers and bale wraps are repaired and reinforced against the elements by an elastomeric coating applied directly to the silage cover after it has been filled with silage feed. The process involves applying a protective coating, typically an elastomeric acrylic coating, to the entire outer layer of the silage cover by spray coating after the coating material has been prepared. The final product is a silage cover with a permanent reinforced overall coating to assist in preventing additional tears and openings in the fabric of the silage cover and sealing holes and damage to the silage cover in an air-tight and moisture-proof manner, thereby protecting the silage feed.
