TOOLS REQUIRED
• Natural bristle brush
•
Lamb’s wool or synthetic roller (3/8- to ½-inch nap)
•
Pump up sprayer (pressure 5 to 15 psi; tip Cone)
*Backrolling recommended after spraying
APPLICATION INSTRUCTIONS
Wait at least 24 hours after washing surface or after rain
before applying H&C® Natural Look Clear Sealer. Only apply
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: On horizontal surfaces, saturate in a single
application. Use enough material to keep the surface wet for
2-3 minutes before penetration. Broom or Back roll out any
puddles until excess material soaks into the surface. Dense
surfaces will only require a single application. Use enough to
completely wet the surface without creating drips, puddles or
rundown. Do not over apply. Test for application rate. On
vertical surfaces, apply the material from the bottom of the
wall upwards spraying so that it will run down the surface at
least six inches below the spray pattern. Typically, the surface
can be reopened to traffic in 1 hour and the surface should be
visibly dry.
Additional Coats: One coat of H&C® Natural Look Clear Sealer
is normally sufficient. Two coats may be required over bare
concrete for maximum protection. Allow a minimum of 4
hours dry time between coats. Apply second coat in a
perpendicular direction to the first coat.
SLIP RESISTANCE
Some surfaces such as inclined driveways, garages, steps, and
patios may require a slip-resistant additive for safety. If more
than two coats are applied, consider using a slip- resistant
additive in the final coat.
CLEANUP
Clean tools and any spills or spatters immediately using soap
and warm water.
MAINTENANCE
Clean light to moderately soiled surfaces with a 50/50
solution of a cleaner degreaser and water or with another
neutral-based cleaner, following the manufacturer’s
directions for use. Use the cleaner full strength for heavy
soiling, such as oil and grease stains.

*Standard test method
used to determine
nonvolatile content in
reactive masonry
water repellants - this
test adds a catalyst to
the water repellant to
measure total solid.
After testing, total
solids for this product
is approximately 4%.
Active Content: 7%
*NOTE: Active content
is a calculated value
based on weight
percent of siloxane in
the total formulation.
Some active content
will be consumed upon
reaction with the
substrate.
