Technical Data
Technical Data Sheet (TDS) CR-546 High Gloss WB Urethane
**This product may only be used on fully cured concrete. Allow a minimum of 28-45 days of cure time after the
concrete is poured to allow ample time for the concrete to completely hydrate.
Product
Concrete Resurrection CR-546 High Gloss WB Urethane is a high gloss, two component water based aliphatic
polyurethane with excellent color enhancement properties. CR-546 High Gloss WB Urethane has excellent
adhesion and hardness properties as well as abrasion, hot tire, and chemical resistance. CR-546 High Gloss
WB Urethane is low VOC and low odor with multiple uses (Garages, shops, showrooms and offices as well as
many other interior applications).
Coverage
Coverage rate is: First Coat: 200 - 300 sq ft per gallon. Second Coat: 250 – 350 sq ft per gallon
Coverage variations depend on concrete surface porosity, texture and amount of material applied. Excessive
build up should be avoided.
Surface Preparation
For a thin film build system (2-3 mils) we suggest either mechanical scarification, acid etching (and the
neutralize to 7 PH), or diamond grinding until an appropriate profile is accomplished. To ensure adequate
adhesion, the substrate must be free of all dirt, oil, dust, and foreign contaminants and applied within the
recommended recoat time of the primer if one was used. Prior to application of the primer a test should be
made to determine that the concrete has an acceptable vapor barrier. This can be done by placing a 4’ x 4’
plastic sheet on the substrate and completely taping down the edges. If after 24 hours, the substrate is still dry
below the plastic sheet, then the substrate does not show signs of eventual hydrostatic pressure problems that
may later cause loss of adhesion. Adhesion tests are recommended prior to using.
Substate and air temperature must be no less than 40 deg. F and not exceed 80 deg F. If applied outside
these limits the sealer may not achieve adequate film formation and may have excessive air entrapment,
bubbles, blushing or hazing. Note that in direct sunlight, substrate temperature can exceed 150 deg F which
can cause extreme bubbling issues.
Application Tools
Apply the mixed material by brush or roller to a prepper surface with a 3/8” nap shedless roller cover at a rate
of 4-6 wet mils within the usable pot life time frame, as well as the recommended temperature and relative
humidity guidelines listed in the Technical Information section. If continuous outgassing in the concrete is
causing bubbles, re-roll the material using a cross rolling method before the material cures to reduce or
eliminate air entrapment. If the material becomes thick while applying keep a wet edge to prevent roller marks.
It is recommended to work in sections usually using control joints as dividers to ensure proper application
results. Do not allow to Puddle! Remove any excess material in joint or low impressioned areas. Puddled
areas may not cure adequately and may cause blush or a white haze. If recoating after 18 hours (temperature
depending) a light sanding using a fine sanding screen may be needed to ensure adequate inner coat
adhesion.
PLEASE NOTE: Applying material outside the suggested parameters may result in product failure. It is
always recommended to test the product in a small, inconspicuous area (on the same concrete substrate) for
desired results prior to application. Coverage reates may vary for all coatings and substrates depending on
porosity, density, texture etc. When applying, do not exceed 400 sq ft per gallon. Applying too thin of a
coating may cause inaququate film formation or performance expectations may be limited. DO NOT USE ON
BRICK.
Mixing Instructions
If mixing less than a full kit, mix Part A only separately by vigorously shaking container AND mix with a drill
mixer for 2-3 minutes prior to blending the smaller kit to ensure uniform distribution of all ingredients (drill mixer
must be used, not a stir stick). Failure to do so may result in craters/fish eyes. Pour a full pre-packaged kit of
4 parts of Part A to 1 part of Part B together and mix well with slow speed mixing equipment such as a jiffy
mixer for 2-3 minutes or until the material is thoroughly mixed and homogenous. Water based two part
systems need to be mixed well for adequate cure and a streak free finish.
Application Recommendations
Apply the mixed material by brush or roller to a primed surface with a 3/8” nap-3/4” nap shedless roller cover at
a rate of 4-6 wet mils within the usable pot life time frame, as well as the recommended temperature and
relative humidity guidelines listed. If continuous outgassing in the concrete is causing bubbles, re-roll the
material using a cross rolling method before the material cures to reduce or eliminate air entrapment. If the
material becomes thick while applying and sticking to the roller, stop applying and discard the mixed material.
At this point it has reached the end of the usable pot life. While applying, keep a wet edge to prevent roller
marks. It is recommended to work in sections usually using control joints or cut lines as dividers to ensure
proper application results. Do not allow to Puddle! Remove any excess material in joints or low
impressioned areas. Puddled areas may not cure adequately and may cause blush or a white haze. If
recoating after 24-36 hours(depending on temperature) a light sanding using a fine sanding screen must be
done.
Please Note: Applying Inside Matter Urethane outside of the suggested parameters may result in job failure.
It is always recommended to test the product in a small, inconspicuous area (on the same concrete substrate)
for desired results prior to application.

Moisture Vapor Emissions/Alkalinity Precautions
All interior concrete floors not poured over an effective moisture vapor barrier/inhibitor are subject to possible
moisture vapor transmission and related high levels of alkalinity that may lead to blistering and failure of the
coating system. It is the coating applicator’s responsibility to conduct calcium chloride and relative humidity
probe testing to determine if excessive levels of vapor emissions or alkalinity are present before applying any
coatings.
Safety
Do not breathe vapors. When using in confined or limited ventilation areas, use appropriate respirator to
protect against breathing vapors. Avoid contact with skin; wear protective gloves and clothing. Always use
eye protection such as goggles, face shield or safety glasses. Read Material Safety Data Sheet before using.
First Aid
Eye Contact: Immediately flush eyes with plenty of water for at least 15 min. while holding eyelids open. Seek
medical attention.
Skin Contact: Immediately remove contaminated clothing. Wipe excess from skin and wash with soap and
water. Seek medical attention if irritation persists.
Inhalation: Remove person to fresh air and provide oxygen if breathing is difficult. Seek medical attention.
Slip and Fall Precautions
OSHA and the American Disabilities Act (ADA) have standards for slip-resistance on pedestrian surfaces. The
coefficient of friction required by ADA is .6 on level surfaces and .8 on ramps. We recommend the use of slip
resistant additives in all sealers or coatings that may be exposed to wet, oily or greasy conditions. It is the
installer and end users' responsibility to provide a flooring system that meets current safety standards.
Engrave-A-Crete, Inc. or its sales agents will not be responsible for injury incurred in a slip and fall accident.
