moisture to cure..
Application Areas
- Waterproofing of Wet Areas in Bathrooms,
Kitchens, Balconies
- Metal and asbestos roofs
- Swimming Pool, artificial lakes and ponds
- Roof gardens , Retaining wall and foundations
- Auxiliary Rooms , Roofs/ Metal/ Asbestos, Terraces
and Podiums (to be protected with screed), etc.
- Can be coated only from positive side on
substructure
- Cut and cover tunnels
Method Of Application
- Allow fresh concrete to cure 28 days
- Concrete surface must clean, strong, free of all loose dirty materials, and dust free,
oil stain, wax, liquid
coating/paint, concrete curing agent, grease or other stains that would affect
waterproof coating adhesion.
- Concrete surface where there laitance, algae, mould, remove them with grinding machine
and clean surface
afterwards
- Prepare cement surface or mineral mix cement surface by cleaning by using grinding
machine or chipping
machine to remove all defect surfaces such as peel off surface, weak concrete, cavities,
etc. Do not use water
to clean surface to prevent accumulation of moisture. Use grinding machine or chipping
machine to
smoothen surface and remove all loose dirty materials, sweep off or use blower to blow
off dirt or vacuum
cleaner to suck in dirt.
- WARNING: Do not wash surface with wate
Repair Cracks & Holes
- For concrete surface with, weak concrete, peel off surface, hollow sound check from
knock at concrete
condition remove by grinding machine or chipping machine till reaching strong concrete
- For concrete surface with pinhole or honeycomb can be apply by using structural repair
cementitious mortar
CIS HYBRID POLYMER to fill in defects area, afterwards allow repair area to cure for 7
days prior to other
work
- For concrete surface with >3mm crack, groove U shape on crack area to big enough for
apply PU Sealant to
seal crack and allow to cure a day prior to working on area
- Clean concrete expansion joints and control joints of dust, residue or other
contamination. Widen and deepen
joints (cut open) if necessary. The prepared movement joint should have a depth of 10-15
mm. The width:
depth ratio of the movement joint should be at a rate of approx. 2:1. Fillet on joints
wall and floor
- For concrete wall and floor should be made fillet/chamfer with PU Sealant. Allow sealant
to cure for a day
prior to other work
- Any corners or angles should be cut.
- Apply a coat of CIS SUPERBOND PU 235 200 mm wide centered over all large cracks and
while wet, cover with
a correct cut stripe of the Geotextile Fabric. Press it to soak
- Saturate the Geotextile Fabric with enough CIS SUPERBOND PU 235until it is fully covered
- Allow 12 hours to cure.
Mixing
- CIS SUPERBOND PU 235 is premix product; stir content till a homogenous paste is form
prior to applying
- Do not add more water when mixing
Application
Pour the CIS SUPERBOND PU 235 onto the primed surface and lay it out by roller or brush,
until all surfaces is
covered. You can use airless spray allowing a considerable saving of manpower. After 12-18
hours (not later than
48 hours) apply another layer of the CIS SUPERBOND PU 235
- For demanding applications, apply a third layer of CIS SUPERBOND PU 235. Reinforce
always with the
geotextile fabric at problem areas, like wall-floor connections, 90º angles, chimneys,
pipes, waterspouts (siphon), etc
- In order to do that, apply on the still wet CIS SUPERBOND PU 235 a correct cut piece of
geotextile fabric, press
it to soak, and saturate again with enough CIS SUPERBOND PU 235
Finishing
- Allow 1st coat to dry 1 to 2 hours prior to applying 2nd coat perpendicularly, do not
add more water in
mixture when applying
- When applying floor to wall joint apply top coat at least 30 cm height above floor level
- Allow top coat to cure 7 days after applying application steps above prior to opening to
traffic
Coverage
1.2 – 1.5 kg/m2 total consumption when applied in two or three layers at 1 mm approximately
dry film thickness
