Master Wall® Products:
- Superior Finishes are formulated with Dirt-Pickup-Resistant (DPR) polymers. Durable Superior Finishes are available in four textures and endless colors.
- Superior Elastomeric Plus Finishes feature elastomeric polymers to help bridge hairline cracks common in One Coat Stucco while keeping the crisp look of our Superior Finishes.
- Specialty Finishes to meet any need. Choose from ultra-smooth to metallic.
- Primecoat Primer seals the surface and increases the brilliance of the finish.
- Leveling Base Coats help fine-tune the surface of the OCS, making it smoother.
- WeatherSTOP Base Coat waterproofs the surface, helping to stop water penetration into the OCS.
- Bulltec Mesh primarily reinforces the OCS surface, adds tensile strength, and helps reduce and control cracking.
