Coverage	One 90. lb (40.8 kg) bag covers approximately 12 to 16 sq. yds. (1 0 to 14.5 m2) with hand application; 8 to 12 sq. yds. (6.6 to 10 m2) with machine application.
Surface Preparation	New portland cement substrates should be properly cured prior to application of Merlex Exterior Stucco. All receiving surfaces must be structurally sound, clean, free of dust, dirt, silicones, paint products, efflorescence or any other contaminant which could impair the natural bond. For hand applications the substrate should be dampened with clean potable water to control suction. Major cracks, holes, or voids should be repaired prior to application.
Mixing	Merlex Exterior Stucco should be mechanically mixed for approximately 15-20 minutes to provide maximum workability. For hand application 8 to 1 0 qts. (7 .5 to 8.5 ltr) of clean water per 90 lb.(40.8 kg) sack will be necessary. For spray application additional mix water may be required. Add approximately half of the required water to the mixer. With the blades running, slowly add the sack of Merlex Exterior Stucco. Allow ample time for initial mixing. Add remaining mix water and complete mixing to produce a smooth workable consistency. For best results, stop mixing after approximately 1 0 minutes, allow to sit several minutes, finish mixing (re-temper). Do not short mix.
Application	Merlex Exterior Stucco should be applied to an approximate thickness of 1/8" (3mm). For hand application: Apply stucco by trowel evenly to the substrate with enough pressure to ensure tight contact. Immediately double back with a second coat prior to floating or texturing. For spray application: Two coats are necessary. Apply the first coat over a dry surface to produce complete color coverage. When first coat has thoroughly dried (usually 24 hours), apply a second coat for texture depth and color uniformity.
Clean Up	Water and detergent. Clean spills and spatters before stucco dries.
Limitations	Do not apply if ambient temperature will fall below 40° F (4° C) within 24 hours. During periods of hot/dry weather moist curing may be necessary. Caution: Variations such as thickness and composition of substrate, surface textures, inclement weather, mixing and application technique, or addition of field additives may impair color uniformity. A 5-1 0% depth tolerance in color is normal. To gain higher color uniformity, apply Merlex Fogcoat bonding cement coating.
