DESCRIPTION:
SPECIFICATIONS:
A-H ARIDSIL VOC is an environmentally friendly, water borne
silane-siloxane based water repelling protection sealer that has
been extensively used and recommended, over many decades, for
concrete and masonry surfaces to prevent weathering, freeze–
thaw damage and water and chloride ion penetration. A-H ARIDSIL
VOC is especially effective on natural and synthetic stone,
unglazed clay tile, brick, stucco and block, exposed aggregate, precasts, wood and masonry surfaces requiring a clear water
repellent material. Complies with AIM VOC Regulations.
All surfaces requiring water repelling protection sealer, as indicated
on plans and specification, shall be treated with A-H ARIDSIL VOC, as
manufactured by Anti-Hydro International, Inc., in strict accordance
with manufacturer’s specifications. Refer to our Waterproofing &
Industrial Floor Details. <-(click me)
A-H ARIDSIL VOC is ready-to-use, water born penetrating silane-
siloxane water repelling sealer that reacts with minerals within the
substrate to create a hydrophobic barrier against water penetration.
It is used on existing and freshly cured concrete and masonry
surfaces to prevent weathering, freeze–thaw damage and water and
chloride ion penetration. A-H ARIDSIL VOC is applied on all concrete
and masonry surfaces above grade. A-H ARIDSIL VOC is an excellent
protection from efflorescence and can be used over concrete and
masonry prior to painting.
A-H ARIDOX 20 VOC & 40 VOC <-(click me SPEC.2-9) are water borne
water repellents with higher active ingredients and superior
®
performance and may be substituted for A-H ARIDSIL VOC.
A-H
ARIDOX 40 & 40M <-(click me SPEC.2-7) are solvent borne, AIM VOC
compliant water repellents with high solids and outstanding
performance and may be substituted for A-H ARIDOX 20 VOC & 40
VOC <-(click me SPEC.2-9).
SURFACE PREPARATIONS:
All existing concrete and masonry surfaces shall be cleaned and free
from laitance, mildew, sand, dust, dirt, oil, grease, chemical films
and coatings and other contaminants, prior to application. Use
power wash or shot blast, if necessary, to achieve the desired
surface condition.
Freshly placed concrete and masonry shall be properly finished,
cured and cleaned as above if necessary. Curing methods must not
inhibit the penetrations of A-H ARIDSIL VOC. Water, chemical, wet
burlap or plastic sheet curing methods are recommended.
Crack control, caulking, patching, and expansion joint sealant can be
installed before application of the sealer. Prior to the application of
sealer, allow at least 6 to 12 hours for curing, dependent on field
conditions.
APPLICATION:
Always apply on a test patch to determine actual coverage rates and
material compatibility.
On new construction, for maximum durability and waterproofing,
“ANTI-HYDRO” <-(click me Spec. 1-1) should be integrally added to
the concrete and mortar during mixing.
Do not apply in windy conditions. Do not apply when substrate and
ambient temperatures are expected to be below 40°F (4°C) over a
period of 12 hours and above 110°F during application.
Typical Uses-
It is recommended that surfaces to be treated shall be dry for
maximum penetration of A-H ARIDSIL VOC. Slightly damp surface may
be permissible, however, do not apply on water saturated surface or
if standing water is visible on the surface.

AIM VOC Regulations.
A-H ARIDSIL VOC is a single coat treatment. Apply A-H ARIDSIL VOC by
brush, roller, or low pressure spray. Low pressure spray is
recommended, where practical, for rapid and thorough application
of A-H ARIDSIL VOC. Apply enough A-H ARIDSIL VOC to allow a slight
rundown. Over- spray will not affect glass, metal, vinyl or painted
area. Remove any over-spray immediately after application by
wiping with a damp cloth.
PRECAUTIONS:
Application-
Do not expose treated surfaces to water, excessive moisture or frost
for at least 24 hours. Use clean tools and containers and clean them

content of container. Do not dilute or add water or solvents of any
kind. KEEP FROM FREEZING.
Do not apply to new concrete with excessive water vapor as it will
prevent adequate penetration.
SafetyUse approved safety glasses, rubber gloves, and coveralls breathing
mask, work boots, and ventilation methods. Do not drink, eat or
smoke in the area. Protect animals, vegetation and food items.
Refer to the product Material Safety Data Sheet (MSDS) for more
details.
StorageStore in a dry cool shaded area. Keep containers tightly closed. KEEP
FROM FREEZING. KEEP AWAY FROM CHILDREN OR INCOMPATIBLE MATERIALS.
MAINTENANCE:
If treated surface becomes dirty, pressure wash with water or soapy
water solution. Rinse with a clean water spray. All due diligence
must be exercised to provide a regular and frequent maintenance
plan to clean and protect the finished surface from severe or
prolonged assault from chemical attack, abrasive attack or similar
abuse.
PACKAGING:
1-gallon, 5-gallon, or 55-gallon containers.
Shelf life is approximately 1 year in original, unopened containers
stored in a dry, cool area.
SERVICES:
Our technical staff is available to review product selection and
detailing during the design stage, provide proper field guidance
during the installation stage, evaluate concrete construction
problems on-site and make recommendations.
