EPOXY FLOOR COATING

 

Epoxy Floor Coating

Introduction SealXpert® Floor Coating is a two-component epoxy floor and deck coating that is designed for heavy pedestrian traffic or light rolling traffic under typical dry service temperatures of -29°C to 60°C (-20°F to 140°F). This coating is both easy and fast to apply.

Features 

1. Applies easily 
2. Fire retardant in the cured state 
3. Resists gasoline, oil, acids, alkalis and aliphatic solvents 
4. Available in yellow, grey or green Typical Applications Typical applications include a finish for concrete and steel ramps, walkways, locker rooms, loading docks, marine applications, machine rooms assembly areas and stairs.

Typical Properties of Uncured Material Volume of Solids, % 62 Mix ratio: by weight by volume 7.5:1 4.4:1 Coverage: Roller 4.6 m² per 3.78 l (50 ft²/gal) Trowel 3.7 m² per 3.78 l (40 ft²/gal) Typical Curing Performance Dry time at 21°C, hours: 12

Note: Temperature and thickness of application affect dry time. Temperatures under 10°C (50°F) will result in a substantially longer cure time. Temperatures over 27°C (80°F) will result in a shorter cure time. The thicker the application, the longer the cure time. Typical Properties of Cured Material Cured at 21°C except where noted Physical Properties: Coefficient of friction , ASTM F 609: Dry 1.2 Wet 1.0 

Direction for Use Surface Preparation: 

• All surfaces to be coated should be sound, clean, dry and free of all contaminants. 
• Loose dirt and dust are best removed by a stiff bristle brush or by blowing down with dry, oil-free compressed air. 
• Oil, wax and grease should by removed by dissolving in a water-based cleaner/degreaser. Rinse thoroughly with fresh water while the dissolved solution is still wet. An alternate method is to clean with appropriate solvents such as mineral spirits as per SSPC-SP-1. It is important that the solvent be removed from the surface while still liquid and not be allowed to evaporate during the cleaning process and redeposit oil or grease on the deck. Ample solvent should be applied to the surface to completely dissolve the grease and oil. The solvent containing the dissolved grease and oil should be wiped up with clean rags before the solvent dries. 
• Depending on concentration and type, chemical contamination should be removed by detergent power washing followed by a liberal fresh water while the detergent is still wet. Allow surface to completely dry. 
• After cleaning, any remaining loose particles should be removed by brushing or blowing with dry, oil-free compressed air.

New Concrete: 

1. New concrete should be properly cured for at least 30 days with good ventilation. 
2. After proper curing, new floors must be swept clean and all contaminants which might interfere with the adhesion of the coating system including laitance, curing membranes, surface hardeners, greases and oils be removed. 
3. An appropriate profile must be created using chemical or mechanical means. 
4. The preferred method to prepare floor surfaces and to remove paint, laitance, curing membranes and surface hardeners is by mechanical removal of the same with a portable shot blast cleaning machine. 
5. Chemical cleaning of laitance and unbounded particles can be accomplished by etching the surface with a muriatic acid or buffered acid solution. Follow acid manufacturer's application and safety instructions. After the acid has finished reacting with the concrete, the residue should be removed by a liberal fresh water rinse or preferably by power washing. Allow the surface to completely dry.

NOTE: Acid etching will not remove oil, grease or wax. If the acid does not bubble or foam when spread on the concrete, the surface should be examined for films or oil, grease, wax, curing membranes, hardeners or other sealers. If such film is present, it must be removed. 

Aged and Uncoated Concrete Floors: 

• Proceed as for New Concrete with particular emphasis on examinations for grease, oil and chemical contamination and subsequent adequate cleaning. 

Asphalt: 

• Sweep to remove all dirt and other loose contaminants. Remove oil, grease, dirt, etc., by dissolving in a waterbased cleaner/degreaser then flush thoroughly with clean water and allow to dry.

Tile and Fiberglass: 

• Glazed or ceramic tile and glazed fiberglass must be sanded to remove all glaze and to roughen up the surface. Remove any residual sanding dust by air blowing or wiping with alcohol.
