The surface must be structurally sound and free of oil,
grease, dust and other contaminants which will affect
the bonding. Any structural cracks and potholes shall be
repaired with a suitable repair mortar from the Polycrete*
range of repair mortars. The surface to be treated should
be presaturated with water prior to application. However,
any standing water shall be removed prior to application.
Polyflex is supplied in two pre-measured parts which just
requires on site mixing. Do not mix more material than that
can be used within the pot life. Part mixing can be carried
out by mixing 3 parts of powder with 1 part of liquid (by
weight). Pour the liquid into a suitable container and slowly add the powder to the liquid. Mix the contents using a slow
speed drill (300-400rpm) fitted to a proprietary paddle
mixer till a homogenous, lump free and creamy consistency
is achieved. DO NOT ADD WATER TO DILUTE THE MATERIAL.
It is recommended to apply Polyflex in two coats to provide
a minimum thickness of 2mm. Each coat shall be applied
@1.8 kg/m2
which will give a dry film thickness of 1mm.
The coating can be applied with a stiff brush or by an airless
spray of nozzle size of 3-4mm and a pressure of 6-7 bar.
After the application of the first coat and whilst the coating
is still wet, embed a glass fibre mesh (Watertite CL 252 or
similar materials) at all corners and other joints for added
reinforcement. The second coat shall be applied after the
first coat dries off completely (6-8 hours @25°C, 50%
rh). For general protection against carbonation and alkali
attacks, the coating can be applied in minimum 1mm
thickness.
Yes. This can be applied on damp surface. But not on waterlogged area
No. Minimum 72 hours curing needed from the last coat.
Yes. It is a non-toxic product suitable for potable water applications
