Handle with care. Before and during use, observe all safety labels on packaging and
paint containers, consult HEMPEL Material Safety Data Sheets and follow all local or
national safety regulations. Avoid inhalation, avoid contact with skin and eyes, and do
not swallow. Take precautions against possible risks of fire or explosions as well as
protection of the environment. Apply only in well ventilated areas.

HEMPADUR MIO 47950
APPLICATION
CONDITIONS:
Apply only on a dry and clean surface with a temperature above the dew point to avoid
condensation. Use only when application and curing can proceed at temperatures above
0°C/32°F.
The temperature of the paint itself should be 15-25°C/59-77°F to secure proper application
properties. In confined spaces provide adequate ventilation during application and drying.
It is important that the surface is completely clean to ensure the adhesion. Any oil, grease, etc. to
be removed by suitable detergent.

Aluminium/zinc spray-metallisation which preferably are to be “sealed” with HEMPADUR 17940
or according to specification.
None, HEMPATHANE or according to specification.

REMARKS:
Weathering/
service
temperatures:
The natural tendency of epoxy coatings to chalk in outdoor exposure and to become more
sensitive to mechanical damage and chemical exposure at elevated temperatures is also
reflected in this product.
Application onto
non-sealed
aluminium/zinc
metallised surfaces
or zincsilicates:A proper mist-coat technique is necessa ry in order to avoid/reduce the risk of “popping” /
”pinholes”. Add up to 50% thinner depending on the actual conditions of application.
Recoating:
Maximum recoating interval:
HEMPADUR MIO 47950 may provide extended recoating properties if it is applied in a way that
allows a MIO structure to develop.
This may necessitate application of HEMPADUR MIO 47950-12130 in reduced filmthickness,
down to 50 micron/2 mils dry filmthicknesses. For such purpose, addition of 5-10% THINNER
08450 is recommended.
General notes on prolonged recoating intervals:
Besides the Note above about MIO, the following applies:
A completely clean surface is mandatory to ensure intercoat adhesion, especially in the case of
long recoating intervals. Any dirt, oil and grease have to be removed with eg suitable detergent
followed by high pressure fresh water cleaning. Salts to be removed by fresh water hosing.
Any degraded surface layer, as a result of a long exposure period, must be removed as well.
Water jetting may be relevant to remove any degraded surface layer and may also replace the
above mentioned cleaning methods when properly executed. Consult HEMPEL for specific advise
if in doubt.
To determine whether the quality of the surface cleaning is adequate, a test patch may be
relevant, however, this test patch should not be a final proof of the durability of the coating
systems.
