ES010 Epoxy Sealer
General Description

"SEAL-IT" Epoxy Concrete Sealer, 21ES10, is a two component solvent based epoxy coating designed as a thin film sealer for application to properly prepared concrete and steel surfaces prior to application of a complete coating system. The applied coating displays excellent resistance to abrasion, fresh and salt water, detergents, and most chemicals as well as good resistance to acids, alkalis, fume and spillage of most organic solvents. It provides extended service life in Industrial, Marine and commercial applications. In UV exposed areas a topcoat is recommended.

ES010 is designed for industrial, and commercial use as a protective maintenance coating for industrial plants, pulp and paper mills, textile mills, chemical processing plants, waste water plants, refineries, food processing plants, commercial buildings and marine structures. For coating and protection of storage tanks, piping, roof decks, water towers, structural steel machinery, plant equipment, marine vessels, offshore structures and other surfaces exposed to humidity, chemicals and corrosive environment.

IconSurface Preparation

Good surface preparation is essential to a satisfactory coating system. Surfaces to be coated should be clean and dry. Remove all oil, grease, mildew or other contamination by solvent or detergent cleaning or other effective means.


Apply in good weather when air and surface temperature are above 50�F and surface temperature is at least 5° F above the dew point. For optimum application properties, material should be between 70° to 100°F prior to mixing and application. Maintain unmixed material in closed containers in protected storage at 40° to 100° F.

Previously Finished Surfaces:

Repair all damaged areas. Remove gloss from previous paint by sanding or "brush blasting" (SSPC-SP7). Remove rust, corrosion products, heavy chalk and loose or peeling paint by "hand or power tool cleaning" (SSPC-SP2) Spot prime with SEAL - IT any bare areas as in new work. If doubt exists concerning compatibility of this coating with the previous system, apply coating to a representative area (55 square feet minimum) and allow to cure and age several weeks. Then inspect for adhesion failure, wrinkling, lifting, blistering or any sign of incompatibility. If there are no signs, coating work can proceed.


Surface must be clean, dry, properly cured and free from all contaminants and laitance. Remove all dust before coating. Apply by brush one coat of "SEAL-IT" Clear epoxy sealer 21ES10 over any crevices, bug holes or spalleds. Apply "SEAL-IT" 21ES10 over entire area to a minimum of 2.0 mils DFT (50 microns ), approximately 5-6 mils wet. Allow to dry at least 12 hours. Application on very porous surfaces may require multiple coats to assure that the surface is completely sealed. Apply a full coat of succeeding coat intermediate and FPUWC series Topcoat, over entire area.


This is a two component coating supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. Use a power agitator for each component. Allow a 15 - 30 minutes induction time @ 70�F and remix before application before using the coating. Usable pot life depends on the temperature of the material (see the Specification Section, above). Agitate before use, with occasional stirring during use. As pot life expires, sag resistance may be reduced. Do not mix any more materials than can be applied in approximately 1 � hours @ 75�F.


Material is supplied at airless spray viscosity and should not require thinning. If required thin with 10% No. 75-37 thinner per gallon if necessary for spray application, No. 7535 for brush application. Add thinner only at a time of mixing. Do not add thinner to thickening material to extend pot life.

Icon Application

Spray application is preferred for proper film build and best performance. Brush application is acceptable for touch up. Roller application may require special care to prevent bubbling and may require more than one coat to attain proper film thickness. Apply at 5.2 mils wet film thickness to achieve 3.0 mils dry film thickness, unthinned.


Safe storage, handling and use dictate that adequate health and safety precautions e observed with this product and any recommended thinners. User is specifically directed to consult the current Material Safety Data Sheet for this product as well as precautions contained on product labeling.
