- 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.
