E155CL Clear Epoxy Primer Sealer | Damp Condition | Moisture Tolerant | Flexible | Low Temp 45°

Cure and Recoat Information

As a primer for epoxy mortars, toppings and 100% solids resins and 100% solids coatings, E155 should be topcoated while still tacky. This will be 30 min. – 1-1/2 hours at 75°F when the E155 is applied at a rate of 150-250 sq. ft. per gallon.

When used as a primer for less than 100% solids solvent coatings, E155 must be dry to touch.  This is typically 4 hours minimum and 6 hours maximum. If the recoat time is in excess of 6 hours, sanding with 80-100 grit open coat paper is required before applying finish coat.

Allow 24 hours for foot traffic and 72 hours for heavy traffic with good ventilation before putting floor back into service.

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 any Gulf Coat Paint 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 square 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.  Ideal preparation includes 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.

Due to the low viscosity of the E155CL Epoxy Primer an acid etch is acceptable preparation as long as it is done correctly with proper neutralization of the acid and a thorough rinsing is performed.

If the substrate is not properly prepared and the appropriate profile is not achieved, failure of the product to adhere to the substrate may occur.

Old concrete surfaces must be structurally sound. Any unsound areas must be repaired prior to proceeding with the resinous installation. For proper patching and repairing, use CF-615 and/or PC-1000 with graded aggregate. Remove existing paint and loose concrete by rough sanding, sandblasting, high pressure water cleaning, shot blasting or grinding. In some cases where plant conditions allow, a stripper may be used to remove excessive build-up of paints or sealers.

MIXING INSTRUCTIONS

E155 is prepared by mixing 1 part Base (Part A) to 1 part Hardener (Part B) with a variable speed drill with a Jiffy mixer. E155 should be used without any induction time. Do not thin, use as supplied.

For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

Use of an improper drill mixer can result in curing problems if the hardener also called activator (Part B) is not thoroughly blended with the resin (Part A) which can cause some areas on your floor to remain soft and not harden properly.  DO NOT USE A PAINT MIXER.  Most mixing problems described above can be traced back to using a paint mixer..  DO NOT HAND MIX as this approach can result in the same problems as using a paint mixer.

APPLICATION PROCEDURE 

For best results, apply by roller, using a medium nap, phenolic core roller cover. Apply an even, uniform, wet film while working material into surface. Do not allow material to puddle. Spread rate will be approximately 150 to 250 sq. ft. per mixed gallon, depending upon porosity of concrete surface.

E155 may also be sprayed, but then should be “back-rolled” to produce a uniform coat. For small areas and “cutting in” use pure bristle brush. Do not apply to surfaces below 45°F or above 100°F.

For safety and product curing, proper ventilation is necessary throughout application and cure. When using pigmented Finish Coats, be sure the batch numbers are all the same to provide a uniform color.

RECOAT TIME

As a primer for epoxy mortars, toppings and 100% solids resins and 100% solids coatings, E155 should be topcoated while still tacky (not gooey). This will be 30 min. – 1-1/2 hours at 75°F when the E155 is applied at a rate of 150-250 sq. ft. per gallon.

When used as a primer for less than 100% solids coatings, E155 must be dry to the touch (does not have to be tack free). Under the same conditions this will be 4 hours minimum and 6 hours maximum. If the recoat time is in excess of 6 hours, sanding with 80-100 grit open coat paper is required before applying finish coat.

CAUTIONS

E155 is flammable. Keep away from all sources of ignition during storage, mixing, application and cure. The Hardener (Part B) either alone or when mixed with Base (Part A) can cause eye and skin burns as well as allergic reactions. When spraying, the use of goggles, fresh air masks or NIOSH approved respirators, protective skin cream, and protective clothing is recommended as a standard practice.
