Mixing Procedures
Since settling may occur, stir using a low speed (200 rpm or less)
power mixer for 30-60 seconds; do not over-mix and do not entrain
air.
Application of Product
Apply with a paint brush, 1/4" or 3/8" nap roller. Apply a thin, even
coat at a uniform coverage rate of 150-300 ft per gallon; do not allow
puddling. Allow product to set until dry to the touch (1 to 3 hours,
depending on ambient conditions and dilution) before applying
subsequent mortars, levelers, and cement tile adhesive.
Drying Time
Allow for MBP to dry before installation of tile or flooring products.
Minimum dry time for polymer modified mortars is between 15 to 60
minutes. Minimum dry time for self leveling underlayment is 1 hour.
Drying time may be longer depending on substrate and/or
environmental conditions. If MBP is directly exposed to ambient
conditions for 3 or more days, re-coat the area.

Store in a cool, dry area. Keep from freezing.
