.DESCRIPTION AND USES .
SEAL & FINISH is a ready-to-use, water base coating that
makes concrete surfaces easier to clean and resistant to
staining. A clear, low-gloss finish seals and protects new
or existing, interior or exterior horizontal concrete. It can
also be applied over or under other concrete coatings or
as a protective layer over concrete stains. The final gloss
will be determined by the initial porosity of the surface and
the number of the coats applied. Multiple coats will
produce a semi-gloss finish. SEAL & FINISH does not
require acid etching and can be touched up or recoated
with simple surface preparation. SEAL & FINISH is not
recommended for some areas. See Label Limitations for
details.

.TINTING SEAL & FINISH .
SEAL & FINISH can be tinted with up to 2 ounces of
universal colorant to produce a transparent colored
coating to simulate the appearance of stained concrete.
Because of its transparency tinted product must be spray
applied to avoid lapping. Spray apply using a garden-type
sprayer or airless sprayer with a small tip (0.011-.0.013)
set at low pressure. Mask adjacent surfaces to allow spray
application to all edges. Do not cut-in edges with brush or
roller. Do not back roll or back brush. Tinted finishes
should not be exposed to hot car tires. A final clear coat is
recommended over tinted product to increase durability.
After it has dried, tinted product cannot be easily touched
up without lapping and a complete second application
may be necessary to correct problems. Additional coats
will increase the opacity of the finish and significantly
affect the final color. Complete removal may be required to
repair or touch-up tinted finishes. Always test apply tinted
product in an inconspicuous area to evaluate the a
appearance, proper application rate and technique.
PRODUCT APPLICATION .
SURFACE PREPARATION
can be applied to horizontal concrete that is clean (free of
waxes and oils), non-glossy and dry. Scuff sand to de-
gloss existing coatings.
PRODUCT APPLICATION (cont.) .
Clean: Vacuum and damp-mop the surface. Use a
degreaser to remove oil or grease stains. Check for the
presence of wax on the surface by sprinkling with water. If
the surface turns dark as the water is absorbed it is free of
wax or sealer and can be coated. If not, a test area should
be applied to ensure adhesion or the surface should be
mechanically abraded.
Dry – If there is any doubt about the dryness of the
concrete, conduct a test by simply taping a piece of 4 mil
plastic sheet 18" by 18" on the bare concrete for 24 hours.
Be sure to tape all four sides. After 24 hours, check the
concrete for signs of moisture. The concrete will be darker
if damp. If moisture is found, allow additional drying time.
New concrete must be cured for 28 days prior to coating.
The surface must be thoroughly rinsed if applied over acid
stain or if surface was acid etched. Un-rinsed acid salts
may damage the coating and cause it to turn white.
COVERAGE
The spread-rate of SEAL & FINISH will vary with the
porosity and texture of the surface. Multiple coats of SEAL
& FINISH can be applied to increase the durability and the
final gloss.
APPLICATION
SEAL & FINISH is ready-to-use, no thinning is required. It
appears milky-white when applied but dries clear. It can be
applied by brush, 1/8” nap roller, pad or sprayer. Stir, do
not shake. Apply an even, thin, wet coat maintaining a
wet-edge to avoid lap marks. Work from a container and
do not pour product onto surface to spread. Stop
application at expansion joints, walls or breaks defined
with masking tape. Do not allow product to puddle. Glossy
surfaces are slippery when wet. Mix anti-slip additive into
SEAL & FINISH to increase slip-resistance in traffic areas.
CLEAN UP
Clean hands and tools with soapy water. Drips and runs
that have dried may be removed using a strong solvent
within 24 hours after application. After that time sanding
may be necessary.
LIMITATIONS
Do not use on flagstone, clay pavers or other non-porous
materials. Chemicals contained in some car tires may
cause coating to lift. Most tire marks can be removed with
commercial cleaners. SEAL & FINISH is not
recommended for areas exposed to gasoline, hydraulic
fluids, heavy fork-lift traffic, cooking oils, or for application
to kitchen counters, bar tops, glazed tile, or to exterior
vertical concrete/masonry walls. SEAL & FINISH does not
