  • Test adhesion after the coating has cured for 24 hours
    by using a knife to cut a crosshatch pattern (#).
    Refer to ASTM D3359 for proper test procedure.
    Use the tip of the knife to pull the edge of the coating
    from the substrate. If the coating comes off over half the
    squares the adhesion is not adequate. If the adhesion
    is not adequate, apply Conpro Point 5 to a new area and
    then re-apply the coating. Repeat the cross-hatch test. 
     
  • Coatings should always be applied to natural break points
    in the structure. If natural breaks do not exist, determine
    the best place to create a break or stopping point.
    Once work has started do not stop until the entire area
    within the break points is complete. 
     
  • Do not overlap coatings. Protect adjacent areas. 
     
  • Always keep a wet edge. This will minimize lap marks. 
     
  • Mix pails from different batches together to eliminate the
    possibility of color variation when an entire surface is visible. 
     
  • The precise addition of water from batch to batch is
    critical when using colored cement coatings. Establish
    a consistent method for measuring liquids and mixing. 
     
  • Over troweling of pigmented cements will affect
    color uniformity.

  • Preparation of horizontal surfaces
    is absolutely critical.
    Refer to the ICRI Technical Guideline 03732
    for complete information. 
     
  • Substrate preparation is critical to the long term
    performance of coatings. The wall surfaces must be
    clean of all contaminants, including paint, dirt, dust,
    loose debris, oils and sealers. 
     
  • Always apply a sample of the material to the structure
    to determine coverage rate and adhesion. 
     
  • Temperature and moisture in the substrate can affect
    the adhesion, drying time and color of coatings. 
     
  • Moisture in the wall is affected by direct sunlight
    and shade. The shaded side of the structure will
    most likely retain more moisture than the East
    and South facing sides.
