Surface
pretreatment: The surface to be repaired must be clean, dry, and
free from fat or oil. Roughen the surface slightly by means of an abrasive
disc, a wire brush, a scraping tool or the like till all shiny patches have
disappeared. Remove all dust completely. Primary coat: Mix ELASTOSAL SPM primer
with RE hardener at a ratio of 100: 7 percent by volume. In a closed packing
drum the mixture remains usable up to 2 hours. Do not mix more primer than
needed. Apply the primer thinly by means of a brush. Apply two layers of
primary coat with absorbent grounds like textile belts, for instance. Let the
primary coat dry (at 20° C) for approx 30 min before applying the repair
filler. Supply of hot air will shorten the drying time. It is also possible to
use any other CR-based ELASTOSAL two-component contact adhesive as a primer, eg
ELASTOSAL H 20.
Application: Fill the
faulty spot with the putty speedily and evenly. The thickness per layer should
not exceed 10 mm. Let the filler dry up each time (approx. 8 h at 20° C and 10
mm layer thickness) till your finger does no longer leave an impression in the
surface. Hot air supply can can considerably shorten the drying time (approx. 3
h at 50 -60°C). Apply the filler repeatedly, each time after priming, if the
filler thickness exceeds 10 mm.
Sealing: ELASTOSAL
SPM primer serves also as a protecting layer. Mix the hardener RE as indicated
above at a ratio of 100: 7 percent by volume. Do not mix more sealant than
needed. Spread the sealant evenly over the surface of the cured filler by means
of brush. After a drying time of approx 1 h (at 20° C) the repair will be
completed, ie the repair spot has become loadable. With hot air supply the
curing time will be accordingly shorter. It is also possible to use any other
CR-based ELASTOSAL two-component contact adhesive as a sealant, eg ELASTOSAL H
20.
Note: For
constant loading the filler must be fully cured. After completion of the repair
the filler further hardens spontaneously. Curing is completed after approx 24 h
(at 20° C). An ambient temperature of at least 20° C is necessary for the
postcuring phase.
