c) New plaster or masonry surface must be allowed to cure and without moisture. Moisture test will be performed to determine the dryness of the surface of plastered masonry wall.
d) Oil and grease contamination should be removed using alkaline cleaner. After removal of the salts, wall should be clean thoroughly with fresh water and let it dry completely. Ensure the moisture content is below 5-10% prior to application of primer.

e) All defects in the surface of the substrata such as cracks, honey comb and angulation or surface imperfection for the cast-in-situ and plastered wall should be repaired with the approved repair materials prior to primer application.
f) Cracks less than 10 mm wide and holes not exceeding 10 mm in diameter shall be filled using a qualified epoxy filler or grout before applying primer/sealer to the surface.
g) Expansion and construction joints shall be cleaned and masked off prior to coating.
h) Surfaces with sharp corners and subject to immersion conditions shall be rounded by forming a fillet with approximately 25 mm radius using an epoxy grout.
i) Sealer/primer shall be use in accordance with the manufacturer’s data sheet and shall be spray applied in a thin coat except for touch-up repairs of small areas [less than 0.1 m²].
j) Paints shall not be used from a container showing a sign of leakage.
k) The painting will be applied after the full curing time of concrete in accordance to SAESQ-001.

l) New concrete must have a moisture content of 4% or less before the painting applications commence.
