Application
1. Clear-Seal Acrylic Urethane Sealer should be
applied using either brush, t-bar, lamb’s wool
applicator, or most pump-up sprayers. We
do not recommend using a roller to apply, as
this may allow too much air, causing bubbles
to stay in the lm.
2. At time of application, moisture content of all
surfaces should be 30% or less as measured
with an electronic moisture meter.
3. 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 or 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 80%.
4. Allow at least 1 hour or until tack-free before
applying a second coat.
Warranty
The information contained herein is offered in
good faith and is believed to be accurate. To be
eligible for a Rainguard Warranty the following
must occur:
1. A site visit must be conducted by an employee
or agent of Rainguard and a Field Inspection
Report completed.
2. A Warranty Application must be fully
completed by the applicator.
3. Field Inspection Report, Warranty Application,
and a copy of the distributor’s invoice must be
submitted to and approved by Rainguard.
This material is only warranted when applied in
accordance with the manufacturer’s guidelines
and warranty procedures. Without adherence to
these specic guidelines, no expressed or implied
warranty of this product is given. Please contact
Rainguard for additional information.
Inspection
Surface must be clean, dry, and free of grease,
paint, oil, dust, curing agents, or any foreign
material that will prevent proper adhesion. The
surface should be porous and be able to absorb
water. Relative humidity in the surface should
be below 80% (per ASTM F-2170). All moisture
should be kept away a minimum of 48 hours
before application and a min. of 48 hours after
installation. This includes sprinklers, rain, fog,
dew, etc.
Drying Time
Wait 24 Hours before opening up to light to
moderate trafc, and 72 Hours before heavy trafc.
Limitations
• Do not apply in temperatures below 50°F or
above 90°F.
• Do not apply on damp or moist surface as it
will whiten and may cause delamination.
• Do not allow any Rainguard products to freeze.
• Prior to coating previously sealed surfaces,
test a small area for adhesion.
• Ok for use as an Industrial Maintenance
Coating, Concrete Masonry Sealer, or Floor
Coating, anywhere in the United States,
including the South Coast Air Quality
Management District (SCAQMD).
• Please become familiar with local Air Quality
laws and regulations prior to applying this
coating. Rainguard bears no responsibility for
improper usage.
Test Panel
Always apply material to a mock wall or test panel.
Test wall or actual surface area to determine
acceptable color, surface porosity, application
rates and methods before starting general
application. It is the duty of the applicator to do a
test area to determine the surface is prepared for
general application of this coating. This adhesion
test can be done by applying a sample in an
inconspicuous area. Allow the sample to dry
and cure. Then cut the coating in a grid pattern
with vertical and horizontal lines cut into the lm.
Then place tape over the cut grid lines and wait
several minutes. Pull the tape up, if any material
delaminates, the surface is not properly prepared
for general application. If the sample is not altered
after removing the tape, the surface is sufciently
prepared for general application.
Precautions
Rainguard recommends the use of slip-resistant
aggregate in all coating or ooring systems that
may be exposed to wet, oily or greasy conditions.
These aggregates can be incorporated into the
materials using different methods to achieve
varying proles and degrees of slip-resistance.
However, textured surfaces can be slippery under
certain conditions. This type of activity on the
ooring surface, maintenance procedures and
type of footwear may all be factors to consider
when deciding the degree of slip-resistance
needed for given area. Rainguard or its sales
agents will not be responsible for injury incurred
in a slip and fall situation. It is the end users’
responsibility to provide for their own safety and to
determine the suitability of these coatings for their
particular application.
