WEATHER RESISTANT
ACRYLIC PAINT PERFORMANCE WARRANTY
1.0 Coverage of Performance
Warranty
We ..................................
the paint Manufacturer hereby warrants that for a period of three (3)
years from the date of Practical
Completion, the paint system shall not be affected by the following
defects:
• Peeling
This condition is manifested when the
paint film peels away or detaches from the
substrate
• Cracking
This condition is manifested by any
visible cracking on the paint film other than that
caused by plastering cracks and
structural defects.
• Fungus/Algae Growth
This condition is established when
there is growth of micro organisms on the surface of
paint films which results in the
marring of the appearance of the paint film through
discoloration.
• Discoloration
This condition occurs when the coating
loses its original color in patches and excessive
discoloration appears.
In the event of the occurrence of any
defects covered under this warranty the Manufacturer shall
take rectification action at his own
cost.
Exclusion of Performance
Warranty
This warranty is subject to the
following conditions:
i) The applicator is to be approved by
the Manufacturer
ii) The Manufacturer reserves the
right to inspect and test the paintwork as and when
necessary.
iii) The substrate must not be
affected by seepage and constant dampness in the wall.
iv) If the walls are persistently damp
with a moisture content above 15% as per reading of
protimeter, this warranty, is not
valid. Such high levels of moisture will cause the paint to
fail and exhibit watermarks,
discoloration, peeling or flaking which are not covered by this
warranty. The onus is on the paint
Manufacturer to substantiate the evidence.
v) This warranty does not cover any
defect, damage or deterioration of the paint system
arising from the structural defects,
mechanical / electrical causes, physical knocks, job
damage, accumulation of atmospheric
dirt, stains on the paint system or repair work by
others without notification to the
Manufacturer.
vi) Claims for incidental or
consequential damages resulting from a breach of this warranty
are specifically excluded.
Procedure for Claims
i) Any defect claims shall be made in
writing and delivered by post or by hand to the
Manufacturer.
ii) A technical team from the
Manufacturer will be despatched to evaluate the nature of the
claim. Should their findings conclude
the defects as within the scope of warranty, then
the Manufacturer shall make good such
defects.
iii) Should the Manufacturer’s
technical team conclude that the defect falls under the
“Exclusion of Performance Warranty” or
other factors alien to the scope of warranty, the
Manufacturer will not be held
responsible for the claim.
iv) Should the Government disagree
with the conclusion of the technical team pertaining to
the defects in particular, then an
independent third party competent in such technical
evaluation shall be appointed to
investigate the disputed defects.
The appointment must seek prior mutual
agreement between the Government and the
Manufacturer.
The findings of the independent third
party shall be conclusive and mutually accepted
by the Government and the Manufacturer.
v) If the finding of the independent
third party are within the coverage of this performance
warranty, all cost shall be borne by
the manufacturer; otherwise such cost shall be borne
by the Contractor.
vi) All claims for the defects must be
received by the Manufacturer not later than 14 days
from the expiry of the warranty
period.
