FORTIS
coatings have been designed so they may be used anywhere in Australia under
most climatic conditions throughout the year.
However for best results, it is advised to follow the application
guidelines.
The
drying time of both epoxy and polyurethanes coatings can be influenced by:
- · Temperature
- · Humidity
- · Airflow
- · Film Thickness
- · Whether 2 pack or single pack
For
example, the recommended application window for single pack moisture curing polyurethane
(FORTIS coat519) is approximately 12 – 35oC and 40 - 80% relative humidity, with
an optimum temperature of 25oC and 60% relative humidity. A significant drop of application temperature
slows down the drying and curing process of the applied coating. This occurs in winter where temperatures are
below 12oC especially in the morning and late afternoon. Also the temperature on the floor can be
significantly lower than the surrounding air temperature and the temperature of
the coating material stored in a van overnight can be extremely low. As such the coating will perform differently. It is best to work within the recommended
application temperature. If you need to
apply under severe adverse conditions, specialist technical advice is
recommended.
The
FORTIS range of high end concrete and timber coatings meets these
specifications and more. The products include primers FORTIS PRIME520,
PRIME820 and coatings FORTIS COAT519, COAT526 and COAT527. Each has
properties enabling high performance in many heavy use flooring applications.
