DESCRIPTION: |
|
NEW 2 OLD - LPL is a
two component, 100% solids, structural epoxy adhesive
for bonding new concrete to old concrete in high
temperatures, or where long pot life and open time are
needed. Can also be used as a binder for aggregate to
create a mortar. |
|
USES: |
| Bonding of new concrete
to old concrete.
Filling voids and joints
in masonry.
Patching, repair.
Grouting dowel bars,
anchors, bolts, etc. |
|
ADVANTAGES: |
| Long pot life.
100% solids, conforms to
VOC regulations.
Moisture insensitive.
High strength.
Easy to apply. |
|
SURFACE
PREPARATION: |
| Surface must be clean
and free of any dust, oil, grease, laitance, curing
compounds or any other contaminants. This should be
achieved by sand blasting, water blasting or some other
mechanical means. New concrete surfaces may be acid
etched with muriatic acid and rinsed thoroughly. The
surface must be dry or damp, and must be free of
standing water. |
|
MIXING
AND APPLICATION: |
| Pre-mix each component
before combining. Mix thoroughly 2 parts component A
with 1 part component B by volume. Mix with spatula or
low speed drill with a mixing paddle. Be sure to scrape
the sides and bottom of the container during the mixing
process. Do NOT mix more than may be used in 60 minutes.
For bonding new concrete
to old concrete, apply mixed material to surface by
brush, roller or spray. Pour new concrete while epoxy is
still tacky. If NEW 2 OLD - LPL loses its tackiness
before concrete is poured, re-coat with fresh epoxy.
Epoxy mortar is produced
by adding up to three parts of clean, dry, bagged sand
by volume. Prime the surface with neat NEW 2 OLD - LPL
and apply mortar with a trowel.
For grouting dowel bars,
anchors, etc., clean all dust out of hole and grout with
neat NEW 2 OLD - LPL. |

LIMITATIONS: |
| Do NOT apply when
temperature is below 40°F.
Do NOT apply to latex
modified mortar or concrete. |
