Overview
  Add-A-PakThe Merlex Add-A-Pak Base and Packaged Color Stucco system uses Color Units, pre-blended, pre-measured formulations of mineral oxide pigment which are individually packaged in 1 lb. (.454 kg) cartons or heat sealed poly bags, to be mixed at the job site with the appropriate Merlex Stucco base.
Benefits
 
  • Eliminates waste.
  • Reduced inventory.
  • Faster availability of desired color.
  • 30 standard colors, custom colors available.
  • Bases include 16/20, 20/30, and Santa Barbara Finish.

Textures
  Merlex Add-A-Pak Stucco System can achieve all the textures available using Merlex Color Coat Stucco.
Substrates
  Merlex Add-A-Pak Stucco System will create an excellent bond to any properly prepared portland cement based surface.
Color Packs
  Add-A-Pak color units are readily available in 30 standard colors. Custom or non-chart colors are available upon request. Any Merlex color can be ordered as Add-A-Pak. The system provides the same high quality stucco finishes as preblended Color Coat, only the color is not integrally blended. Requires the addition of one Add-A-Pak color unit to each bag of base to achieve the proper color.
Bases
  The System uses two standard bases to achieve most colors: A Base (white portland cement), and B Base (grey portland cement). Other combination bases (C, D, & E) are available upon request to achieve unusual colors. Note: Base designation will be determined by the color that is selected and should always be properly coordinated.
Samples
  3" x 3" sand finish samples are immediately available in all 30 standard colors. Other colors, textures, and sample sizes may be ordered by special request. Merlex takes pride in its quick response time in processing your sample orders.
Coverage
  Coverage will vary depending on which type of stucco base is used and how it is applied. Follow the instructions on the appropriate Merlex Color Coat or Santa Barbara Finish Stucco product specification sheets.
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 containment 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
  Mechanically mix one 90 lb. (40.8 kg) bag of the desired Merlex base material to a stiff consistency until all lumps dissipate. Add all of the Add-A-Pak color units that will be required (1 unit per each sack of base) for the total batch to be mixed. Add enough water to sufficiently loosen the mixture and then add remaining sacks of base. Continue to mix for at least 20 minutes to provide maximum workability. Do not short mix.
Application
 

Application technique will vary depending on which type of stucco base is used. Follow the instructions as outlined on the appropriate Merlex Color Coat or Santa Barbara Finish Stucco product specification sheet.

Compatibility
  When the Add-A-Pak base and color system is selected it should be used for the entire project. Do not merge with premix stucco. There will always be a slight, but discernible, color difference.
Clean Up
  Water and detergent. Clean spills and spatters before stucco dries.
Packaging
  Add-A-Pak color units are packaged 30 units per case. Each unit is properly marked with the Merlex color number, base designation, and mixing instructions.
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. To gain higher color uniformity, apply Merlex FogCoat bonding cement coating.
