Water Barriers and Flashings

Master Wall® manufactures Rollershield, Trowelshield and WeatherStop secondary water barriers for use with our systems. All are 100% acrylic formulations for long life and durability.

Rollershield is easily roll-applied using painting equipment and Trowelshield is the trowel-grade version with excellent body and workability. WeatherStop is our thicker trowel-applied water membrane that is mixed with Portland cement.

WeatherStop Flashing and Sheathing Tapes are peel and stick tapes that are repositionable at initial installation and develop strength over time. They are used with our Commercial Drainage EIFS or can be specified as part of our other systems.

Rollershield & Trowelshield Flashing Tapes are lightweight yet strong flashing tapes can be used both in the seams and to flash into openings or penetrations. When embedded into Rollershield or Trowelshield they offer both waterproofing and crack-bridging abilities.

DV Roll is a starter strip for drainage or venting. It is easily installed and comes in long rolls for ease of use.

Drainage Media features approved drainage mats for our Aggre-flex and stucco systems.
