CEMTEC AL PU COATING
ALIPHATIC POLYURETHANE COATING
Any remaining material must be kept in tightly
sealed.
Before application, mix CEMTEC AL PU COATING
with a slow speed jiffy mixer for minimum 5
minutes. If mixed by hand, mix CEMTEC AL PU
COATING thoroughly until a homogeneous mixture
is obtained.
The first coat of CEMTEC AL PU COATING should
be applied at the rate of 0.2 ltr/square meter. For
best results, apply by airless spray. Roller or brush
may be used but care should be taken not to cause
air bubbles. Spread CEMTEC AL PU COATING

COATING is extremely abrasion resistant
compared to normal paints, making it ideal for use
in garages, workshops, machine rooms, etc. In
addition, the coating is resistant to chemicals
including alkalis, solvents and oil. CEMTEC AL PU
COATING exhibits a non-yellowing nature and it
is therefore highly recommended for exterior
applications. Generally used as a glazecoat for
flooring systems.
Limitations:
It is a moisture reactive material, hence containers
that have been opened should be used up within
two days. It forms a skin when exposed to air.
DIRECTIONS FOR USE
Some precautions need to be followed for
application of CEMTEC AL PU COATING.
Application should not be stopped part way across
an area and than completed several hours later.
