For Best Results

Work from the container—do not pour product onto surface to spread.

 
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.

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 provide protection against hydrostatic water
pressure, wind driven rain, or efflorescence.
