MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Product must be stored in an area that will bring the product to room temperature prior to using. Continuous storage should be between 60 and 90 degree F. Keep from freezing

SURFACE PREPARATION: Preparation methods may vary depending on the system being applied. For a complete system thickness that is higher than 10 mils dry, a fine brush blast (shot blast), is recommended. To assure a trouble free bond, all dust, oil, dirt, foreign contaminants and laitance must be removed. It is recommended to perform a moisture test to determine that the concrete has an appropriate vapor barrier. This can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. Once 24 hours has passed, and the substrate is still dry below the plastic sheet, then the substrate does not show signs of eventual hydrostatic pressure problems that may later cause disbonding. This test does not guarantee, however, that there may not be future hydrostatic pressure issues in the future.

PRODUCT MIXING:  This product has a mix ratio of two parts A to one part B by volume (volumes approximate).  Standard packages are in pre-measured kits and should be mixed as supplied in the kit.  After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free.  After mixing, transfer the mixed material to another pail (the transfer pail) and again remix.  The material in the transfer pail is now ready to be applied on the properly prepared surface. This product has a short usable pot life of about 15 minutes which is substantially shorter than the actual gel time for the product. Applying the product beyond the usable pot life can result in surface irregularities.

Improper mixing may result in product failure. 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.

****IMPORTANT NOTE AFTER MIXING:****

Once parts A&B are thoroughly mixed, immediately pour 100% of all mixed product on the floor in a ribbon pattern, S or W shape over the area you want that amount of product to cover. The risk of leaving product in the bucket is that it will become hard and reduce the working time by a minimum of 50% and may harden and start smoking in the bucket before you get back to it.

PRODUCT APPLICATION: The mixed material can be applied by brush or roller   When using a roller use a 3/8” nap lint free professional grade epoxy roller cover. It is best to maintain a wet edge to avoid roller marks. Direct sunlight or high temperatures may cause visible roller making during application. Applying the product too thick may result in solvent entrapment and product failure. Relative humidity can have a dramatic influence on the curing characteristics. The product will dry quicker and have less working time when the relative humidity is higher while a lower relative humidity will lengthen the dry time and working time. This product has a short usable pot life of about 15 minutes which is substantially shorter than the actual gel time for the product. Applying the product beyond the usable pot life can result in surface irregularities.

RECOAT OR TOPCOATING:Installing multiple coats of this product is acceptable. If recoating this product, be sure that all of the solvents have evaporated from the coating during the curing process. Refer to the cure schedule as a guideline to follow, in addition we strongly recommend to test the coating before recoating or topcoating. This is done by pressing your thumb on the coating in multiple places to ensure a fingerprint impression is not visible. If there is no impression visible, then coating the floor can be done. Note, colder or hotter than 75 degrees can affect the curing time schedule  Prior to coating the floor, make sure there are no contaminants exist. If contaminants or a blush exists, remove with a standard detergent cleaner and ensure floor is clean and dry prior to coating. It is recommended to degloss the previous floor prior to coating to ensure a trouble free bond.

CLEANUP/FLOOR CLEANING:Use Xylol for cleanup. When cleaning the floor, CAUTION! Some cleaners may affect the color of the installed floor. Test each cleaner used in a small area, ensuring no damage occurs. Restrict the use of the floor to light traffic and non-harsh chemicals until the floor is fully cured, refer to the cure schedule. Allow the floor to remain completely dry during the curing process.

RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.

Reach out to us for personalized product recommendations for YOUR project at 630-675-4509 or [email protected].

Can E344QC be applied directly to concrete?

No — E344QC is not recommended for direct-to-concrete application.

👉 Best system:

1. Epoxy primer / base coat (like E707HB epoxy or similar)
2. Decorative layer (optional flakes, metallic, quartz- check out at our Decorative Floors Page)
3. E344QC as the protective topcoat

This ensures proper adhesion and long-term durability.

How durable is E344QC?

E344QC is built for high-traffic and industrial environments:

• High compressive strength (>12,000 psi)
• Strong abrasion resistance
• Resistant to chemicals like acids, solvents, and oils (varies by exposure level)

👉 Ideal for garages, forklifts, commercial traffic, and heavy use areas.

Is E344QC UV stable?

Yes — E344QC is an aliphatic polyaspartic, meaning:

• Will not yellow
• Maintains gloss over time
• Great for areas with sunlight exposure (interior with UV exposure)

What finish does it have?

E344QC provides a high-gloss, clear finish that enhances:

• Metallic epoxy systems
• Flake floors
• Solid color epoxy

👉 You can also tint it using pigments for a colored topcoat.

How many color options are available?

• Clear (most popular for topcoats)
• 13 pigment color options available

Pigments are added separately, giving flexibility for custom looks.

What is the coverage rate?

Coverage depends on the system:

• Coverage ~160-600 sq ft per gallon

👉 Thicker applications = lower coverage. For quantity rate information reach out to us at 630-675-4509 or [email protected].

How long do I have to work with it?

E344QC has a very short working time (~10–15 minutes) after mixing.

⚠️ Important:

• Mix small batches
• Pour immediately after mixing
• Do not leave in the bucket (can heat up and cure rapidly)

For additional application tips reach out to us today at 630-675-4509 or [email protected].

What temperature can it be applied in?

• Application range: 50°F – 90°F
• Humidity affects cure speed (higher humidity = faster cure)

Can multiple coats be applied?

Yes — E344QC can be applied in multiple coats if needed for:

• Additional protection
• Increased gloss
• More build

Is E344QC slippery?

Like most high-gloss coatings, it can be slippery when wet.

👉 Recommended:

• Add anti-slip additive for safety in:
  • Garages
  • Commercial spaces
  • Wet environments

How does E344QC compare to epoxy topcoats?

E344QC Polyaspartic vs Epoxy Topcoat:

• Faster cure (hours vs days)
• Better UV resistance (no yellowing)
• Higher abrasion resistance
• Higher gloss finish

👉 It’s typically used as an upgrade topcoat over epoxy systems.

What systems is E344QC best used in?

Popular systems include:

• Epoxy + Flake + E344QC
• Epoxy + Metallic + E344QC
• Epoxy + Quartz + E344QC

👉 It acts as the final protective layer that locks everything in.

Is this good for DIY or contractor use?

Both — but with caution:

✔ Great for experienced DIYers
✔ Preferred by contractors
⚠️ Requires fast application due to short working time. For additional application support reach out to us at 630-675-4509 or [email protected]. 

What are common mistakes to avoid?

• Applying too thick (can cause bubbles or failure)
• Not mixing properly (Pro tip: Use Jiffy Style Mixer)
• Letting material sit in the bucket
• Applying directly to concrete without primer

Why choose E344QC for your project?

Choose E344QC if you need:

• Fast return-to-service (same day use)
• High-gloss professional finish
• Strong chemical & abrasion resistance
• Reliable topcoat for epoxy systems
