POLYBIT® POLYFLEX COMBO Internal and external waterproofing of potable water reservoirs, anti-carbonation protective coating to exposed concrete structures, protective coating on structures exposed to sea water, sealing light aerated blocks, pre-cast joints, waterproof coating on roofs, domes, tunnels, swimming pools, lift wells, spillways, surge shafts, pre-cast slabs and other wet areas, permanent ponding.
Available pack size: 20kg
The surface must be structurally sound and free of oil and
grease, dust and other contaminants which will affect the
bonding.Any structural cracks or potholes shall be repaired
with a suitable repair mortar from the Polycrete* range of
repair mortars. Light mechanical grinding or high pressure
water jet cleaning of the concrete surface can be done to
remove any contaminants from the surface. The surface
to be treated should be presaturated with water prior to
application. However, remove any standing water from the
concrete surface just before applying the coating.
Polyflex Combo 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 only exact half the
quantity supplied on both components. Pour the liquid (2
cans) 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 until a
lump free creamy consistency is obtained. DO NOT ADD
WATER TO DILUTE THE MATERIAL AT ANY STAGE
It is recommended to apply Polyflex Combo in two coats to
provide a minimum thickness of 2mm. Each coat shall be applied @1.4 kg/m2 which will give a dry film thickness of
1mm. The coating can be applied with a stiff brush or an
airless spray of nozzle size of 3-4mm and a pressure of 6-7
bars. After the application of the first coat and whilst it is
still wet, embed a Watertite CL 252 mesh in all the corners
and other joints for added reinforcement. The second coat
shall be applied after the first coat dries. for 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 compatible with spray applied polyuethane foam
