AllPro Epoxy Floor Coatings, 100% Solids, Self-Leveling, Part A, Light Grey, 2 Gallon

Surface Condition: The surface to be coated must be clean, sound, and dry. Remove dust, dirt, laitance, grease, oil, curing compounds, waxes and any other contaminants. Any rough spots, projections or surface imperfections should be removed or patched to achieve a level surface prior to the application of any coatings.

Old or Previously Coated Concrete: Concrete surface must be cleaned and mechanically prepared using shotblasting, sand blasting, and/or diamond grinding. All oils, sealers, curing agents, waxes and fats must be removed prior to product application. Do not apply onto wet substrates. Chloride, moisture, and pH levels should be checked prior to application. If the moisture content exceeds 4%, one of our moisture vapor barrier activators must be used. All cracks, divots, depressions, or surface imperfections should be filled and repaired prior to application. Divots or depressions must be filled with a slurry of AllPro Epoxy and sand or aggregate, AllPro Crack Filler or an approved patching compound.

New Concrete: New concrete should be allowed to cure for a minimum of 30 days. Compression resistance of concrete must be at least 25 MPa (3625 lbs./inch2) after 28 days and traction resistance must be at least 1.5 MPa (218 lbs./inch2). Shotblasting, sand blasting, and/or diamond grinding is required to remove the surface laitance that appears during the concrete finishing and curing process.

Surface Profile: All existing coatings, laitance, curing compounds, and bond breakers must be removed via shot blasting, scarifying or diamond grinding and provide a suitable profile in accordance with ICRI CSP-2 or CSP-3, but not to exceed the thickness of the coating system. Abrasive blasting or grinding is to leave the concrete in a uniform texture. Over-blasting will result in reduced coverage rates of subsequent coats of primer and finish. Sweep and vacuum any remaining dust, dirt, or contaminants with a wet/dry vacuum. All dirt, foreign contaminants, and laitance must be removed to assure a trouble-free bond to the substrate.

Moisture Content Testing: After the floor has been cleaned and abraded, moisture content tests are highly recommended. Three (3) tests are required for the first 1,000 Sq. Ft. and an additional test for every additional 1,000 Sq. Ft. in accordance with ASTM F1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride Moisture Emissions Test. Other acceptable test methods are ASTM F2170 In-Situ Probes or ASTM F2659 Non-Destructive Electronic Moisture Meters. The moisture content must be less than four (4) pounds (4%) of moisture per 1,000 square feet per 24 hrs. for the standard converter. The 5751 Epoxy Vapor Barrier and 5752 Epoxy Fast Set Vapor Barrier Activators are more surface tolerant and can withstand up to 25 pounds of moisture per 1,000 square feet per 24 hr.

Crack Filling & Patching: Patch divots in the floor with a slurry of AP-91000 AllPro Epoxy and sand or aggregate, AP-91024 AllPro 100% Solids Fast Set Crack Filler or an approved patching compound. Fill cracks with SP-91024 AllPro 100% Solids Fast Set Crack Filler or AllPro Polyurea Crack Filler in accordance with the product data sheet. Expansion joints shall be filled with an approved joint sealant.
