1. Concrete Sealer should be applied
using a hand pumped garden sprayer
(do not atomize) or low-pressure airless
spray equipment.
2. If using airless spray equipment we
recommend a spray tip size of .035
to .051. Spray head should be held
8 to 12 inches from the surface so
that the ood coat runs down the wall
approximately 6-12 inches below the
point of application.
3. Avoid application in windy weather.
4. Trigger gun off at the end of each pass
to avoid using excessive materials.
Stop all applications only at corners,
joints, seams, or edges.
5. Multiple coats may be applied. Whiting
or yellowing will not occur.

Do not apply to concrete if moisture content is greater
than 15% as measured with an electronic moisture
meter. Do not apply materials in climates where freezing
temperatures have existed prior to application. Allow
adequate time for surfaces to thaw. Establish that air,
surface, and material temperatures are above 40°F
(4.4°C) and at least 5°F above the dew point prior to
painting. Do not apply at temperatures below 40°F
when temperatures are expected to drop below 40°F
within 48 hours of application. Do not apply if rain, snow,
or lower temperatures are expected within 48 hours. Do
not apply if relative humidity is greater than 90%
Use material in a well-ventilated area. Protect the work
of other trades. Protect shrubbery and other plants with
drop cloths. Protect automobiles and all other areas not
to be coated from overspray. Remove overspray from
any windows, automobiles, metal, etc. as soon as
possible should it occur. To prevent permanent staining,
clean spills or leaks in a timely manner.
Store materials in a well-protected area between 45° and
90°F. Avoid freezing temperatures, direct sunlight, and
moisture. Keep away from heat sources.
