E352P Hi-Gloss Polyester Polyurethane Floor Coating | Chemical Abrasion Resistant | Exterior Interior

A two component polyester aliphatic isocyanate polyurethane coating.  This special CRU formulation is used to impart the highest chemical resistance, gloss and color retention of a polyurethane coating, yet retain the outstanding tough, abrasive resistant film which provides excellent exterior durability, chalk resistance, color stability and long term gloss retention.

Ideal for use as a clear or pigmented topcoat in both interior and exterior Industrial, Commercial and Marine applications.  Not for use directly on unprimed surfaces and not designed for submerged service.   Can be applied to existing epoxy, polyaspartic or urethane coatings (do not apply to acrylic paint) after proper preparation including sanding and wiping with acetone solvent right before application (apply E352P as soon as acetone solvent is dry).

The clear E352P-CLR is is ideal as a final clear top coat for color quartz, vinyl/acrylic chip decorative floors, pigmented epoxy and polyurethane coatings, epoxy slurries/mortars, interior wood, brick and warehouse floor coatings.

For vertical topcoat applications suggest our E370P Hi-Gloss Polyurethane.

Times may be longer for thickness above 2.5 dry mils.  For safety and proper product curing, good ventilation is necessary when painting indoors or in confined areas.  Be sure the batch numbers are all the same to provide  uniform color.  Heaters that emit carbon dioxide and carbon monoxide can cause the coating to yellow.

APPLICATION TEMPERATURE: 50ºF – 100ºF Do not apply to surfaces below 50°F or above 100°F. Do not apply over dew or frost. The surface temperature should be at least 5°F above the dew point.

SURFACE PREPARATION  E352P Polyester Polyurethane is a top coat only and is not recommended to be used directly over unprimed surfaces. Apply over appropriate primers or intermediate coats. Surfaces must be free from all oil, grease, dirt, water, or other foreign matter.  E352P Polyurethane is not recommended for immersion service.

Steel: All surface contamination, such as dirt, dust, grease, oil and other deposits must be removed prior to abrasive blast cleaning. Solvent cleaning as outlined in Steel Structures Painting Council’s Specification SSPC-SPI should be used to remove all foreign matter. If previous service has left surface deposits of chemicals, they also must be removed by pressure washing and followed by a thorough water rinsing.

Remove all rust, mill scale, loose paint and any previous existing coatings by dry abrasive blasting all steel surfaces before applying the coating system.

Recommended primers for the E352P are E15M Chemical Mastic, PC-2.8 Epoxy Coating, PC-517 Epoxy Mastic,  E100 Aluminum Polyurethane and PC-110 Epoxy Primer. Follow the recommended recoat time per label in structions. In some cases an intermediate coat may need to be applied when a 3 coat system is necessary or desired.

Marginally Prepared Steel Surfaces:

Degrease and chemically clean surfaces in accordance to SSPC-SP1 Solvent Cleaning spec to remove all oils, grease, and other soluble contaminants.  If steel is chemically contaminated (e.g., acid, caustic, or salts), high pressure water cleaning at a minimum of 5,000 psi is recommended to remove chemicals.  The pH of steel should be tested to ensure that surface of steel is between 7.0-8.5 pH.  After the above process has been completed, power tool cleaning is to be done.  Power tool clean to remove all mill scale, loose rust, loose paint and other detrimental foreign matter.  Apply two coats of our E100 Aluminum Polyurethane at 2-3 mils DFT.  Minimum recoat time for E100 is two (2) hours, maximum recoat time is six (6) hours at 75°F and 50% relative humidity.  E15M Chemical Mastic or PC-636 Low Temp.  Epoxy may also be used as a primer under the E352P Polyester Polyurethane on marginally prepared surfaces.

Concrete/Masonry Surfaces:

New concrete must be cured at least a minimum of twenty-eight (28) days before applying a coating.  All laitance, efflorescence, chemical contaminants, grease, oil, and other foreign material must be removed.  The  prepared surface must be clean, dry, and structurally sound.  Accepted methods of surface preparation are  dry abrasive blast, wet abrasive blast, vacuum shot blast, high pressure water blast, scarifying, scabbling and acid etch/water rinse.

Voids, cavities, spalled areas, and other structural defects should be trowel-grouted smooth with CF- 615  Epoxy Crack Filler or E1000 Epoxy Mortar.  Rub smooth with a hand grinding stone any burrs or high protruding aggregate left uneven by troweling.

Consult Gulf Coast Paint regarding the testing of the concrete for proper pH, vapor barrier testing and surface porosity.

Acceptable primers for the E352P Polyurethane are PC-149, PC-155, and PC-1703 Epoxy Concrete Primers. An Epoxy Intermediate coat may be needed if higher film build is necessary.   Products such as E15M, PC-636, PC-275, PC-517 or 100% solids materials such as PC-1803 or PC-1850 can be used.


Stir each component to a uniform consistency, using a slow speed explosion proof variable speed drill with a Jiffy mixer.  Make sure any pigment settled to the bottom is incorporated.  Do not vary proportions.  E352P is prepared by mixing 2 parts Base (Part A) to 1 part Hardener (Part B) with the power mixer.  For rolling, thin up to 15% using SU-93, as needed (can substitute thinning up to 5% – 10% with a 100% Xylene).

For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

NOTE:  Always wear protective gloves and clothing while mixing and applying E352P.  Do not get on skin.


Best method of application is conventional or airless spray use up to 10% Thinner.  Flush equipment thoroughly with MEK solvent before using and use a moisture trap on the air supply.

Surfaces must be free from all oil, grease, water or other foreign matter.  Surface should be dry and above 50°F and rising.  Relative humidity should not exceed 85%.  CT-352 is moisture sensitive during application and initial cure.  Do not apply if surface temperature is within 5° of Dew Point.  Not recommended on floors, susceptible to hydrostatic pressure.   For safety and proper curing, proper ventilation is necessary throughout application and cure.  Any foodstuff and furnishings in the application area should be removed prior to application.  When using pigmented Intermediate Coats, be sure the batch numbers are all the same to provide a uniform color.

Do not apply to surfaces below 50°F or above 120°F.   Do not apply over dew or frost.  The surface temperature should be at least 5°F above the dew point.

RollerBest method of application is using ¼” – 3/8” shed resistant phenolic core rollers.  Pour material in a ribbon along the floor.  Roll in the same direction, always keeping a wet edge.  Do not over roll product. Thin up to 10% by volume with SU-93 Reducer, depending on temperature.

Brush – E352_ can be brushed by using pure Chinese bristle brushes.


E352P is flammable.  Keep away from all sources of ignition during mixing, application and cure.  Contains Aliphatic Polyisocyanates, N-Butyl Acetate, Xylene and PM Acetate.  The HARDENER (Part B) and mixtures of BASE (Part A) with HARDENER (Part B) can cause eye and skin burns as well as allergic reactions.  The use of goggles, fresh air masks or NIOSH approved respirators, protective skin cream and protective clothing is a recommended standard practice when spraying.  This product is sold without warranty as to performance expressed or implied.  Users are urged to make their own tests to determine the suitability for their particular conditions.


  • Do not apply over frost surfaces or extremely high humidity conditions.
  • Do not apply over expansion joints.
  • Do not apply if the surface temperature is within 5° of the dew point.
  • Partially used containers must be reclosed tightly to prevent moisture in air from reacting with material and forming a tough skin.  Skin can be removed and remaining material used.  Be sure to stir.
