• Use MIMIC and/or Matrix for the full depth
  of the repair. Building out with another material
  may cause damage to the substrate and
  cracking of the repair mortar. Cracking of this
  type occurs because of the difference in the
  substrate materials (i.e. the material used
  to build out and the existing stone). 
   
• The precise addition rate of water
  is critical to maintaining consistent color.
  Establish a consistent method for measuring
  water and maintain it throughout the job. 
   
• In hot weather cure by misting with
  water 2 - 3 times a day or use burlene.
  Do not use curing agents or allow polyethylene
  or burlap to touch the surface of the repair,
  as this will cause whitening or changing of color. 
   
• Finishing technique will change the final color.
  A smooth trowel finish will be lighter in color
  than a shaved finish. 
   
  
• The texture of the repair mortar will be more
  rough the earlier it is shaved. Conversely,
  a fine finish is achieved by shaving late in the
  curing process. The more rough the texture
  the darker the color will appear. The more
  fine the texture the lighter the color will
  appear. The actual color of the product is
  not changing. It is the way light reflects off
  a texture that causes the difference.
  

• Surface preparation is critical successful stone
  repair. Most natural stone is highly absorptive and must be thoroughly saturated (SSD) prior to placing the repair mortar. 
   
• Mix only as much material as can be placed in
  15 - 20 minutes. Do not re-temper. Re-tempering
  can cause cracking and will affect the final color.
