- Re-New Surface: is a crystal that is mixed with water
at a specific ratio. The liquid is then used in cement and
washed sand to acquire a specific slump. Once the mixture
has been brought to the desired slump, it is placed on the damaged
concrete surface, and finished as desired.
- Re-New Surface: overlays may be placed on bridge decks,
sidewalks, curbs, and concrete road surfaces. They are
also used in multi-level structures since the overlays only need
to be thick enough to replace the deteriorated surface, therefore
not adding additional weight to the existing structure.
- Re-New Surface: overlays are slightly lighter in colour
than the regular concrete due to the lighter coloured sand being
used in mixture.
- Re-New Surface: overlays are freeze-thaw and salt-resistant,
and are also more flexible, making these overlays less apt to
cracking.
- Re-New Surface: overlays have up to 6700 PSI in seven
days at a mix of 3 to 1 (sand-to-cement ratio) by weight, in
a slurry mix (test
results).
- Re-New Surface: is available in 16
colours. Tests (CSA A23, 2-9C) show a compressive strength
of 2600 PSI at seven days.

- Re-New Surface Colour
Sealer: protects
the colour overlay against UV rays as the colour pigments are
organic and will fade without the protection. It makes the
overlay water-repellent, reduces straining, washes easily, is
non-slip, and is applied with a rough surface paint roller. It
covers 200 to 250 sq.ft. per gallon and should be resealed every
five to seven years, depending on surface wear.
- Re-New Surface Industrial
Sealer: is an elastomeric
liquid styrene eaylate that will protect the concrete surface
against oil, gasoline, anti-freeze and most chemicals, and it
will also prevent concrete dusting. It can be applied by roller
or trowel. This sealer bridges all cracks
that do not affect structural strength. This sealer remains flexible
on the surface, allowing it to bridge existing and new cracks
after application.
- If Re-New Surface overlays
have a downside, it is that it must be applied in a specific
way. If the instructions are not followed exactly, the overlay
could fail. Failures have been approximately 10 per cent
over the years, and these were at working joints where the overlay
was not cut, marked or placed exactly over the existing joint.
