G4 POLYURETHANE
VARNISH “SEALER”
G4 Pond Seal is a “moisture
cured” one-component polyurethane, which forms a non-porous, tough, durable but
flexible seal.
Seals porous substrates such as concrete,
brick and porous stone.
G4 will not seal, lightweight block, these need to be cement rendered before application of G4.
In general it is advised that all substrates are
rendered below the water line.
G4 can be used at low temperatures, down to 0º C and
in areas of relative high humidity.
G4 cannot be used on bitumen but will not damage butyl
rubber liners.
G4 is easy and quick to use, simply brush on the
recommended coats in a day.
WORKING INSTRUCTIONS
Ensure cement render is clean, dry and porous – highly
trowel led ridged surfaces are not advised.
New render should be allowed to harden for 21-28 days
depending on conditions.
Reinforcing fibres in the cement render must be burnt
or sanded off before coating.
Repair cracks and damaged areas.
Apply first coat by brush, avoid thick coats and allow
to become fingerprint dry, or dry enough to walk upon
carefully, approx. 60-90 minutes depending on humidity.
Apply subsequent coats following the above
instructions.
Do not allow longer than 4 hours to elapse between
each coat, normally 3 coats of G4 standard are sufficient but on very porous or
rough surfaces a 4th coat may be required.
Rain will affect uncured G4 so make provision for
covering if rain is suspected.
Allow to harden for 72 hours before washing down with
clean water.
Then follow aquarist instructions.
CONSUMPTION
Varies slightly depending on porosity. On normal porous
cement renders:
G4 Standard 4 coats = 840 g/sq.metres
(for 4 coats).
CLEANING
Clean brushes and tools with cellulose thinners or
acetone; alternatively wash out in hot water and detergent and dry.
