APPLICATION INSTRUCTIONS
H&C ENDURAPOLISH Clear Liquid Hardener & Densifier,
should be used prior to application of H&C ENDURAPOLISH
Lithium Protective Finish for the ideal polishing system to
increase hardness and durability of the surface.
Apply H&C ENDURAPOLISH Clear Liquid Hardener and
Densifier under dry conditions. Air and concrete surface
temperatures should be above 50°F and below 95°F for 24
hours following application.
How to Apply: Stir thoroughly before and during application.
Do not shake or whip air into sealer, and do not reduce. Apply
with a pump up or HVLP sprayer evenly at the rate of
approximately 400-500 sq. ft. per gallon. Lightly broom out any
puddles immediately after the material has been applie
d.
Allow H&C ENDURAPOLISH Clear Liquid Hardener and
Densifier to remain on the surface for 20-30 minutes. DO NOT
LET ANY AREA DRY OUT during this time. Add more H&C
ENDURAPOLISH Clear Liquid Hardener and Densifier as
needed in order to maintain a uniformly wet surface. After
material has penetrated and is no longer glistening on the
surface, continue grinding and polishing to the intended final
surface profile and desired finish. If using a wet polishing
method, or on integrally colored concrete, it is recommended
to use an auto scrubber and water to remove residual slurry
between abrasive disc grits.
CLEANUP
Clean tools and any spills or spatters immediately using soap
and warm water. Clean hands immediately after use with a
waterless hand cleaner.
MAINTENANCE
Routine sweeping, mopping, washing and mechanical
scrubbing if floors with neutral pH cleaners / water is
recommended. Clean surfaces coated with H&C
ENDURAPOLISH Lithium Protective Finish using a mixture of 3
parts water to 1 part H&C CONCRETEREADY Cleaner
Degreaser. DO NOT USE Acidic or Citrus cleaners to maintain
the floor.
