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, 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 floors 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. Gulf Cost Paint recommends 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 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, using E-615 and / or E-1000 Epoxy Concrete Repair Kit 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 

Do not mix until surface has been primed with E-155. Best results are obtained if both Base and Hardener are stored at or above 75F for 12 hours prior to mixing to ensure normal viscosity. E-615 can be used neat or made as a mortar.

E-615 is prepared by mixing 2 parts Base (Part A) to 1 part Hardener (Part B) by volumed with a power mixer for approximately two (2) minutes. The importance of thorough mixing is extremely critical to ensure proper curing of the E-615. Up to 1 part of fine, salt free, Kiln dry aggregate can be mixed with 1 part of E-615 to make Epoxy Mortar.

When applying coatings over the E-615, grind or sand with coarse grit to achieve a profile. Solvent wipe to remove the dust.

CAUTION

E-615 is not a fire hazard; the flash point is 300F. However, under conditions of fire it will burn and release potentially toxic fumes. The Base portion is relatively inert physiologically. The Hardener portion contains amines and related materials. These can cause irritation and possibly chemical burns to the skin and eyes. This is also true for mixture of Base and Hardener. Wear safety glasses, gloves and protective clothing when using E-615. 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.

What is E615 epoxy crack filler used for?

E615 is a 100% solids, two-component epoxy crack filler designed to repair and resurface concrete, steel, and wood surfaces. It’s commonly used for filling cracks, patching damaged concrete, rebuilding surfaces, and leveling areas exposed to heavy wear or chemicals.

The E615 can be used vertically, overhead & horizontally.

Can E615 be used on vertical or overhead surfaces?

Yes. E615 is a trowelable epoxy paste that works on horizontal, vertical, and overhead applications, making it ideal for walls, ceilings, and structural repairs where traditional self-leveling products won’t stay in place.

Is E615 epoxy crack filler waterproof or moisture tolerant?

E615 is moisture-insensitive and can cure in the presence of moisture, making it suitable for damp environments like manholes, sewer systems, and industrial facilities.

How strong is E615 compared to concrete?

E615 has a compressive strength of approximately 7,800 psi, which is stronger than typical concrete, making it ideal for structural crack repair and heavy-duty resurfacing.

Can E615 be used to fill large cracks or holes?

Yes. E615 can be applied up to 1 inch thick in holes and ½ inch vertically, making it effective for deep crack repair and rebuilding damaged areas.

Can you mix E615 with sand or aggregate?

Yes. E615 can be mixed 1:1 with silica sand to create an epoxy mortar for patching, resurfacing, or rebuilding larger sections of concrete.

How long does E615 take to cure?

• Working time (pot life): 20–30 minutes
• Recoat time: 8–24 hours
• Full cure: Typically within 8 hours at 75°F

This makes it a fast-curing epoxy crack repair solution for industrial and commercial jobs. Note: higher or lower temperatures can affect cure schedule.

Is E615 safe to use indoors?

Yes. E615 is zero VOC and non-toxic once cured, making it suitable for indoor use in warehouses, plants, and commercial facilities.

Does E615 require a primer before application?

Yes. For best results, a primer such as E-155 epoxy primer is recommended before applying E615 to ensure proper adhesion and long-term durability.

Can E615 be coated or painted over?

Yes. After curing and proper surface prep (grinding/sanding), E615 can be top-coated with epoxy or urethane coatings for added protection and aesthetics.

What temperature should E615 be applied in?

E615 should be applied between 50°F and 90°F for optimal performance and curing.

Is E615 good for industrial or chemical environments?

Absolutely. It offers excellent resistance to chemicals, abrasion, and impact, making it ideal for:

• Chemical plants
• Wastewater facilities
• Refineries
• Manufacturing environments

How much coverage does E615 provide?

Coverage depends on thickness, but approximately:

• 9.6 sq ft per gallon at ¼ inch thickness

This makes it suitable for targeted repairs and resurfacing projects. For assistance in confirming how much of the E615 to order for YOUR project reach out to us at 630-675-4509 or [email protected].
