Simiron 800CF Epoxy Crack Filler, Haze Gray, 2 Gallon Kit

Surface Preparation: Concrete must be sound, clean, dry and free of contaminants such as dirt, dust, grease, oil, silicones and other contaminants that may negatively affect adhesion. Concrete should be a minimum of 28 days old. 

This product is intended for cracks up to 1/8 inch in width , but larger patches can be made with this material. Remove all unsound concrete from within the crack/defect to be repaired and thoroughly vacuum all debris and dust from within the crack opening.

Moisture Vapor Barrier: A suitable moisture barrier must be in place for concrete slabs on-grade. If a moisture barrier is not in place, seasonal variations in ground moisture can cause excessive moisture vapor transmission (MVT) regardless of results measured prior to coating application. For 16 mils of 1150FC, MVT rate must not exceed 12 pounds per 1,000 square feet per 24 hours, as directed by ASTM F1869. The relative humidity (RH) of the slab must not exceed 85%, as directed by ASTM F2170. If there is a moisture situation in excess of the above rate, the use of Simiron MVB Moisture Vapor Barrier Primer may be required. Consult a Simiron Representative for details and application procedures.

Application: 1.5-Gallon Kits of MVB should not be split Nominal 3-gallon units of MVB Fast cannot be split.

1. Measure out equal volumes of Base and Activator in a pail or on a rigid, flat surface like a piece of cardboard and mix them together thoroughly with a putty knife or spatula until the material is thoroughly mixed and uniform in color. Mix only an amount of material that can be used in the allotted work time. Improper or insufficient mixing may result in product failure.
2. Apply the mixed material using a marginal trowel, putty knife or any other suitable tool. Push the material into the repair area, and remove excess material by scraping flush with surface.
3.  When repairing cracks that are less than 1/8 in. thickness, many epoxies can be placed immediately over the applied crack filler. Alternatively, overcoat the material after it sets up but within 24 hours. If excessive amounts are spread well beyond the repair areas, check the cured areas for any possible amine blush (a whitish, greasy, or film that is not glossy) prior to coating over this material. If a blush is present, it can be removed by any standard type detergent. cleaner prior to topcoating or recoating. 

Dry Time: Open working time: 35-45 Minutes, Tack free: 8-10 Hours, Light Foot Traffic: 24 Hours, Full Cure: 5 days, all subject to ideal surface & air temerature with relative humidity of 72°F (25°C) 50% RH. Ideal temerature range for application Air Temp: 45°–95°F,  Surface Temp: 45°–95°F, Material to be applied: 60°–85°F. 

Coverage: 0.13 cu. ft. per gallon or 1,228 lineal ft. of 1/8 in. x 1/8 in. cracks. 12 months from date of manufacture when stored indoors in the original unopened container at 60°F–85°F (16°C–29°C) in a dry location with humidity below 65%. Do not allow materials to freeze.

Clean Up: Clean up mixing and application equipment immediately after use with acetone or xylene; do not use alcohol. Follow solvent manufacturer’s safety instructions. Be sure to follow all local, state and federal regulations when disposing of materials.
