4. Carefully remove excess adhesive from around the edges
of the dolly with the included cotton swabs.
5. Allow to cure per the adhesive manufacturer's instructions.
The decision of when to cut around a dolly is dependent on the
specified standard, specification or contractual agreement. The
primary purpose for cutting through the coating is to isolate a
specific diameter test area. When the decision to cut into the
coating has been made, it is recommended to cut all the way
through to the substrate. As a minimum, it is suggested to carefully
cut away any excess glue from the dolly application process. This
typically prevents a larger area of coating from being pulled away
from the substrate, resulting in a higher pull-off pressure.
Cutting Instructions
1. Cut through the coating around the edges of the dolly with the
included cutting tool, removing any excess glue.
2. Clear away any debris from the cutting process.
NOTES:
- Cutting may induce coating surface flaws such as
microcracking that may alter test results.
- For coatings with strong lateral bonding, it is recommended to
cut completely through the coating down to the substrate.
Drilling Template
When testing very thick coatings, the optional drilling template
accessory may be preferred.
