To finish strong, you need a leveling base coat with superior weather resistance to stop water before it enters your stucco or wall. Flexible, fibered SuperiorShield WeatherSTOP remains flexible, and weather resistant and embeds easily into Master Wall® mesh. WeatherSTOP is an alternative to a separate fluid-applied water barrier.

• WeatherSTOP blocks water before it soaks the stucco, keeping your building dry.
• Protects the stucco and keeps it safe and dry.
• Dry stucco doesn’t support mold growth.
• Bridges minor hairline cracks, flexible.
• Levels the surface, making the surface smooth for finishing.
• It can be used with Master Wall Mesh for even better crack resistance.
• Works with Master Wall Superior and Superior Elastomeric Plus textured finishes.
