READ ALL INSTRUCTIONS CAREFULLY BEFORE

SURFACE PREPARATION
Proper surface preparation is critical to performance. Allow
newly poured concrete to cure for a minimum of 28 days.
Sweep away all loose dirt and debris and remove any
vegetation. If necessary, use a wire brush or sander to
remove any loose or unsound concrete or masonry.
Remove any efflorescence with RockSolid Efflorescence
Remover (sold separately). Clean the entire surface,
including any oil or grease spots with RockSolid Heavy-
Duty Cleaner (sold separately). Scrub surface with a stiff
bristle brush or broom. Rinse thoroughly with fresh water.
Repeat as necessary to completely clean the concrete.
For proper penetration for maximum adhesion, use
Rust-Oleum Concrete Etch (sold separately). Follow label
instructions carefully. When etching is complete, be sure
to rinse 3 times with clean water and scrub with a stiff
bristle brush while rinsing.
Allow the surface to dry completely before applying
RockSolid Concrete Stain. Wipe your fingers over the
clean, cry concrete. If you see any dust or powder on your
fingers, repeat the scrubbing and rinsing until the surface
is clean. If your fingers remain clean, the surface has been
properly prepared and is ready for staining.
Existing coatings or sealers must be removed prior to
applying RockSolid Semi-Transparent Concrete Stain.
Test for a sealer by lightly sprinkling water on the surface
of the concrete. If the water droplets bead up rather than
soak into the concrete, then a sealer is present. The
sealer will have to be removed by an alternate method of
surface preparation, such as abrasive blasting or grinding.

SURFACE PREPARATION
WARNING! If you scrape, sand or remove old paint, you
may release lead dust. LEAD IS TOXIC. EXPOSURE TO
LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS
BRAIN DAMAGE, ESPECIALLY IN CHILDREN.
PREGNANT WOMEN SHOULD ALSO AVOID
EXPOSURE. Wear a NIOSH-Approved respirator to
control lead exposure. Clean up carefully with a HEPA
vacuum and a wet mop. Before you start, find out how to
protect yourself and your family by contacting the National
Lead Information Hotline at 1-800-424-LEAD or log on to
www.epa.gov/lead.
APPLICATION
RockSolid Semi-Transparent Concrete Stain is ready to
use. Do not thin. Apply only when air (ambient)
temperature is 50-90ºF (10-32ºC) and the relative humidity
is below 85% during the day and night. Do not apply in
direct sunlight. Do not apply if rain is expected within 48
hours. Avoid applying late in the day when temperatures
are falling. The formation of dew can interfere with proper
curing. Use in well ventilated areas.

To minimize overspray, properly mask adjoining areas
and avoid staining in windy conditions. Protect
delicate foliage from overspray. Apply using a
standard pump sprayer with an adjustable spray tip.

If using more than one gallon, intermix all cans of the
same product to ensure color uniformity. Stir
container thoroughly to mix product.

Use a brush to trim the perimeter and hard-to-reach
areas.

Fill the pump sprayer with product; then fully
pressurize the sprayer. Set sprayer tip to a fine mist
and apply in a circular or figure eight pattern 10-12”
from the surface, working is 6’ x 6’ sections. Start and
stop the sprayer just off the work area to prevent drips.
Do not pour the product directly on the surface or
allow product to puddle.
Apply just one color of stain to produce a uniform
appearance or choose multiple colors to create unique
combinations.

Lightly apply 1-2 base coat(s) to achieve 100%
surface coverage. Additional coats will result in a
more uniform appearance. Allow sufficient dry time
(approximately 1 hour) between coats and before
applying accent color9s).

If desired, apply accent color(s) over the base coat to
provide the desired level of contrast.

If desired, lightly mist the original base color over the
entire surface to further “soften” the look.

On smaller areas, use handheld trigger sprayers,
paint brushes, rags or sponges to apply the stain.
