Master Wall's SuperiorShieldWeatherSTOP TrowelOnAir/WaterBarrier doubles as both a leveling base and an effective weather barrier, streamlining installation by eliminating the need for a separate fluidapplied membrane. Water-based and easy to clean, it mixes readily with Portland cement to a trowelready consistency and provides coverage of about 200 - 220ft per 5gal. pail when embedding single-layer mesh, or 66 - 200ft with double-layer mesh. With a working time of roughly one hour, and dry time near twelve hours under standard conditions, it empowers contractors to keep projects on schedule while fortifying wall assemblies.
