Working Time: Does not affect normal working times.

Drying Time: Does not affect normal drying time. Do not fog walls treated with Stucco Ad-Liquid. Protect from rain and temperatures less than 40°F (5° C) for a minimum of 24 hours.

Application/Storage Temperatures: 40°F (5°C) to 110°F (43°C). Store out of direct sunlight.

Application Procedure

Temp: 40-110F (5-43C) • Working Time: 1.5 hr • Dry Time: 72 hrs at room temperature, working and drying time will vary with temperature and humidity.

Application Procedure
Job Conditions – Air and substrate temperature for application of Stucco Ad- Liquid must be 40°F (5°C) or higher and must remain 40°F (5°C) or higher for a minimum of 24 hours. Surface must be clean, dry, structurally sound and free of efflorescence, oil, grease, form release agents, paint and curing compounds.

Temporary Protection – Provide temporary and permanent protection to prevent water entry behind the stucco.

Proportioning – Proportions will vary depending upon use. Reference Master Wall® Cemplaster Fiberstucco specifications for warranted system
proportions. In general, the product will achieve minimal properties such as improved crack resistance with levels as low as one quart (0.95L) per 280# (127 kg) of mixed stucco. Substituting Stucco Ad-Liquid for water in the stucco mix provides optimal performance. Vary proportions to meet specific project requirements or contact Master Wall for recommendations.

Mixing – Use non-air entrained stucco mix. Slowly add Stucco Ad-Liquid to the mixture and mix for a short time (about 1 to 2 minutes) to avoid air

Apply stucco mix according to locally, regionally and nationally accepted practices to the specified thicknesses. When drying, Stucco Ad-Liquid forms a film or sheen that aids in the hydration of the stucco.

For Professional Results

Do not use with air entrained cement mixes or with air entraining admixtures.

Do not use where air circulation is limited.

Protect from extreme water exposure for a minimum of 24 hours.

Fogging the wall is not recommended when Stucco Ad-Liquid is used.

Do not use as a stucco surface primer or external bonding agent—use Primecoat or Roller-flex depending upon application.

Do not over mix.

Clean Up
Tools and equipment can be cleaned with soapy water when the stucco mixture is wet.
