CONCRETE RESURRECTION CR-531 Inside Epoxy (100% Solids Clear Epoxy)
**This product may only be used on fully cured concrete. Allow a minimum of 28-45 days of cure time (or until
a pH reading of 10.5 or less is achieved) after the concrete is poured to allow ample time for the concrete to
completely hydrate. It is recommended that a calcium chloride (or similar) moisture test be completed on any
floor prior to Inside Epoxy application.

Coverage (varies based on concrete surface porosity and amount of material applied)
¾ Gallon Kit:100-200 sq ft for Clear Coat
50-75 sq ft for Metallic Coating
3 Gallon Kit:400-800 sq ft for Clear Coat
200-300 sq ft for Metallic Coating
Surface Preparation
A fine to medium shot blasting or the use of a diamond grinding machine to obtain a surface profile of a CSP -
3 to a CSP - 5 is suggested for ultimate adhesion.
A test should be made to determine that the concrete is dry; this can be done by placing a 4 x 4 plastic sheet on
the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then
the substrate should be ready to coat. More advanced moisture testing kits should be used on floors with
suspected moisture problems.
Apply coating to a clean surface that is completely dry and free of oil, dirt, grime, wax, detergent or any
incompatible paint or coating. RAC Stained concrete must be neutralized, thoroughly cleaned, and dry prior to
sealing.WRC Stained concrete must be completely dry prior to sealing.
Concrete must be completely dry prior to sealer application. It is strongly recommended that a surface probe
moisture meter be utilized to verify the surface is dry. After visually determining the concrete is dry, test a
minimum of 10 different areas of the concrete with the moisture meter. Pay special attention to cracks, control
joints, and slab edges.
Mixing Instructions - Clear
Open the one gallon can of Part A resin and add the entire contents of the one quart Part B hardener. Use a
spatula to empty the entire contents of the Part B hardener into the Part A can. It is critical to have an exactly
portioned mixture, which has been prepackaged for you to eliminate any guesswork or measuring. After
combining the two components use a paint mixer on a low speed drill for 2 minutes to completely mix the
components. Be careful to not whip air into the mixture, and be certain to scrape the sides and bottom of the can to combine all molecules. Incomplete mixing or an off balance mixture will result in a coating that will
remain soft forever.
Mixing Instructions – Pigmented
When a pigmented epoxy is desired add the desired amount of pigment into the resin (part “A”) and mix
completely using a paint mixer on a low speed drill. When desired color is achieved follow the directions above
for adding and mixing in the hardener (part ”B”).
***WARNING*** Use only Concrete Resurrection epoxy pigments.
Application Recommendations
CONCRETE RESURRECTION CR-531 Inside Epoxy can be applied at a rate of 3 to 8 mils thick, using a
roller, squeegee or trowel within the usable pot life time frame, as well as the recommended temperature and
relative humidity guidelines listed in the Technical Information section. If concrete conditions or aggressive
mixing causes air entrapment, then an air release roller tool should be used prior to the coating tacking off to
remove the air entrapped in the coating. If the material becomes thick while applying and sticking to the
application tools , 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 streaking. It is recommended to work in sections
usually using control joints as dividers to ensure proper application results. Do not allow to Puddle!
Product is FDA compliant in a continuous cleanable film.
Thinning -- Do not thin.
Additional coats
Previously coated surfaces must be mechanically cleaned and abraded using a floor machine (buffer) with 80
mesh sanding screen prior to application to ensure adequate inner coat adhesion.
Please Note: Applying CR-531 Inside Acrylic 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. Coverage rates may vary for all coatings and substrates depending on
porosity, density, texture etc.
Clean Up
Discard used consumable items such as roller pans, roller covers, brushes, etc.

Limitations
Air and substrate temperatures must be minimum 50F
Do not apply when air or surface temperature exceeds 90 degrees (F) or LAP marking / poor penetration /
bubbling may result. Do not apply to wet or damp concrete, moisture will inhibit penetration of the sealer and
cause improper curing, flaking or lifting of the sealer. Do not apply if dew may condense on the surface before
the sealer has cured. Allow for extended drying times during cold weather / high humidity.
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.

Slip and Fall Precautions
OSHA and the American Disabilities Act (ADA) have now set enforceable standards for slip-resistance on
pedestrian surfaces. The current coefficient of friction required by ADA is .6 on level surfaces and .8 on ramps.
Engrave-A-Crete recommends the use of angular slip-resistant aggregate in all coatings or
flooring systems that may be exposed to wet, oily or greasy conditions. It is the contractor and end users’
responsibility to provide a flooring system that meets current safety standards. Engrave-A-Crete
or its sales agents will not be responsible for injury incurred in a slip and fall accident.
Epoxy Chip Floors
When an “Epoxy Chip” floor is desired there are multiple methods to apply product.
Some of the design factors to consider before application is color of pigment in the epoxy and chip color.
Technique 1: (1-2 person team)
Roll or squeegee the epoxy across the width of the job and approximately 5’ deep. Then broadcast the epoxy
chips onto the wet epoxy approximately 4’deep. This will allow you to roll the next section of epoxy into the
first area without picking up chips on your roller cover. Continue to repeat this process until complete coverage
is obtained
Technique 2: (3-5 person team)
Coat the entire surface to be treated with the desired color of epoxy. Wearing epoxy spikes or golf spikes, walk
carefully onto the floor and broadcast the entire surface with epoxy chips.
Final Coat:
After the epoxy has become tack free (typically 6-10 hours) a coat of clear Inside Epoxy should be applied to
the top surface in order to protect the epoxy chips. If additional protection is desired, a top coat of Inside
Urethane may be applied over the Inside Epoxy (allow 12 hours of cure time and mechanically abrade the
Inside Epoxy prior to the Inside Urethane application).
Tips
Spikes:
Wearing spikes (epoxy spikes or golf shoes) will allow you to walk out over the epoxy to broadcast chips or fix
any issues. ***WARNING*** Walking on wet epoxy with spikes is like walking on ice. Move slowly and
carefully.
Broadcasting Chips:
Prior to your first job practice broadcasting chips onto “dry” concrete to test your technique. It is best to throw
a small handful of chips up into the air and let them scatter as they fall down. This technique helps to avoid
“clumps” of chips on the floor.
