MIXING AND APPLICATION INSTRUCTIONS
SURFACE PREPARATION
In all cases of surface preparation, the pH should be checked. A pH reading of 7.0 to 8.5 is acceptable. Also, a Water Dissipation Test should be made on random areas of the floor to determine if the proper degree of porosity has been achieved. Before the installation of our products, the substrate should be examined for moisture. Test for moisture vapor transmission using ASTM F-1869 Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor using Anhydrous Calcium Chloride. The maximum allowable rate is 3 lbs per 1,000 sq feet per 24 hours. Test for relative humidity in concrete floor slabs using Probes according to ASTM F-2170. This test measures the presence relative humidity of the slab below the surface. The maximum relative humidity should be below 80%.
New concrete must be cured at least a minimum of 28 days before applying a coating. On-grade slabs must have moisture vapor barrier in place. All laitance, sealers, efflorescence, chemical contaminants, grease, oil and other foreign material must be removed. The prepared surface must be clean, dry and structurally sound. We recommend mechanical preparation by means of shot blasting or diamond grinding to achieve a CSP-2 or CSP-3 profile, in accordance with the International Concrete Repair Institute (ICRI). The profile should reflect something similar to a 60-100 grit sandpaper. If the substrate is not properly prepared and the appropriate
MIXING INSTRUCTIONS
E77 is prepared by mixing 1 Gallon Base .80 (Part A) to 1 Quart Hardener .20 (Part B) with an explosion proof variable speed drill and Jiffy mixer. E77 may be thinned up to 10% with Xylene. Overthinning reduces the high film build capability.
Roller – Use a 3/8” – ½” short nap phenolic core, shed resistant roller cover. Roll in the same direction always keeping a wet edge. Do not over roll product. Change out roller covers and mixing pails frequently to avoid build up of curing
material. Do not drain or scrape out mixing pails on floor. There can be un-mixed resin on sides of pails, which can cause soft spots on floor.
Brush – Use pure bristle brush. E77 is recommended only as a primer/base coat. Topcoat with a pigmented finish coat or a full flake broadcast. Do not apply if the temperature is within 5° of the Dew Point.
CAUTIONS
E77 is Flammable. Keep away from all sources of ignition during mixing, application and cure. The Hardener and Base can cause eye and skin burns as well as allergic reactions. Use goggles, fresh air masks or NIOSH approved
respirators, protective skin cream and protective clothing. This product is sold without warranty as to performance expressed or implied. Users are urged to make their own tests to determine the suitability for their particular conditions.
