Extended Information

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.
