This Material requires a minimum truckload purchase. Use Product # 467 instead for smaller quantities.

EPOXYSYSTEMS PRODUCT #451 is an aromatic, liquid applied, single-component, moisture cured polyurethane floor coating for use in indoor applications such as industrial plants, mechanical rooms, and locations where surfaces must withstand pedestrian traffic.


Composition: A single component, aromatic based , moisture-cured polyurethane coating.

Basic Uses: EPOXYSYSTEMS PRODUCT #451 is primarily used as a protective top coat of the ELASTO-DECK 5000 M.R. deck coating system. It may also be used as a durable finish that protects interior floors against occasional chemical spillage, dirt, grease and oils. EPOXYSYSTEMS PRODUCT #451 gives floors a well maintained look while retaining a glossy appearance. Dusting of concrete floors is minimized when the surface is sealed with EPOXYSYSTEMS PRODUCT #451. EPOXYSYSTEMS PRODUCT #451 is intended for interior applications only. Coating will discolor if exposed to sunlight.

Limitations: Containers that have been opened must be used up within one or two days since it is a moisture-reactive material. It sets up when exposed to air.

Colors: Concrete Grey, Tan

Sizes: Available in 1 gallon cans, 5 gallon pails and 55 gallon drums.


Surface Preparation: EPOXYSYSTEMS PRODUCT #451 may only be applied to dry, clean surfaces. It is recommended to prepare concrete floors by acid-etching or sandblasting. EpoxySystems Product #889 Concrete Primer or EpoxySystems Product #888 Epoxy Concrete Primer may be required prior to applying EPOXYSYSTEMS PRODUCT #451 depending on the concrete substrates condition. All oxidation and rust must be removed from metal surfaces and all metal must be primed with Epoxy.com Product #887 Metal Primer.

Application: EPOXYSYSTEMS PRODUCT #451 may be applied by all conventional means, including spray equipment, paint rollers, and brushes. The rate of application is typically 125 sq. ft. per gallon (3.06 m2/liter). Additional coats may be applied after an overnight cure. It is important not to wait for more than 24 hours before recoating if additional coats are desired. Allow a final cure time of 48 hours before the coating is exposed to traffic.

Caution: An appropriate aggregate, such as aluminum oxide, monterey sand, or other suitable anti-skid material, must be added to the final or next to last coat, in sufficient size and quantity to prevent the coating from being slippery.


All products proven to be defective in manufacture will be replaced at no charge. Since the use of these products is beyond our control we cannot accept damages in excess of the purchase price of these products.


If EPOXYSYSTEMS PRODUCT #451 is damaged, it can be repaired by cleaning the surface with M.E.K. and recoating it with EPOXYSYSTEMS PRODUCT #451 system.
