.DESCRIPTION AND USES .
OKON
®
Seal & Finish is a ready-to-use, water-based
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.

.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, the tinted product must be
spray applied to avoid lapping. Always test apply the tinted
product in an inconspicuous area to ensure that the
desired expectations are met.
PRODUCT APPLICATION .
SURFACE PREPARATION
OKON Seal & Finish can be applied to properly prepared
horizontal concrete surfaces. Concrete surfaces must be
clean, dry and sound prior to application of the product.
Remove all waxes and oils using a commercial degreaser.
Scuff sand soundly adhered previous coatings to remove
gloss.
Vacuum and damp-mop bare concrete surface. 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.
PRODUCT APPLICATION (cont.) .
Concrete surfaces must be completely dry prior to
application. Check for dryness by taping a 2 foot square
piece 4 mil plastic sheet on the bare concrete for 24 hours.
Be sure to tape all four sides. After 24 hours, check the
concrete for signs of moisture. If the concrete is dark,
moisture is present and the concrete should not be coated.
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.
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, ⅛” nap roller, pad or sprayer. Stir
thoroughly. DO NOT SHAKE. If using a brush or pad,
apply an even, thin, wet coat maintaining a wet-edge to
avoid lap marks. Work from the container. Do not pour
directly on the floor. Stop application at expansion joints,
walls or breaks defined with masking tape. Do not allow
product to puddle.
For spray application, use 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.
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 application to kitchen counters,
bar tops, glazed tile, or to exterior vertical concrete or
masonry walls. Seal & Finish does not provide protection
against hydrostatic water pressure, wind driven rain, or
efflorescence.
