7001 Polyurethane Primer Concrete & Steel | Quick Cure | Exceptional Adhesion | Low 35F Temp

COVERAGE RATE

CURE SCHEDULE

APPLICATION TEMPERATURE: 55-90 degrees F with relative humidity below 75%

MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product at normal room temperature. Continuous storage should be between 60 and 90 degree F.

Preparation:

Concrete must have a minimum 28 day cure prior to application. Remove any curing agent, form release materials, oils, wax, moisture or any material that may effect bonding. *Perform a Moisture Vapor Test before making the coating application on concrete. Clean by abrasive “brush-off” blast. Provide rough profile minimum 2 mils. Review ASTM D4259 Abrading Concrete and ASTM F1869 Measuring Moisture Vapor Emission. Seal/repair all bug holes, cracks and spalls, see ASTC data sheets on 830, 4034 and 3004 (joints). Use an ASTC primer over filled cracks and voids.

Mixing: 

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.

Metal Preparation:  

Round off sharp edges and rough welds. Burrs and weld splatter should be completely removed. Surfaces must be clean, dry and free of any contaminants. Provide a clean rough profile via sanding, grinding or sandblasting. Vacuum the topside of all horizontal and sloped surfaces. Fill pitted steel using ASTC epoxy paste fillers for steel, leave flush with steel surface.

Carbon Steel:

Immersion or Severe Exposures – SSPC-SP-5 Near-White sand blast. Mild Exposures: SSPC-SP10/NACE 2. near-white blast cleaning should have an anchor profile of two mils. Welds, seams, edges, etc. grind/blast smooth and provide 2 mil profile.

Non-Ferrous Metal:

SSPC-SP-7 (Brush-Off Blast Cleaning) Coatings applied to these surfaces may not achieve the same degree of adhesion and toughness.

Curing Time & Temperature:

7001 may be coated over with other products when the product solvent has flashed and the product is just becoming tack free. The set time without the accelerator is based on the environmental temperature. Application temperatures range from 35°F to 125° F.  Allow the product to “flash” its solvent content before applying top coat materials.  If the product is allowed to complete its full cure and becomes hard, the surface must be sanded/abraded to provide a profile to the cured product before applying additional primer. Always apply the top coat or product approximately 1 hour and not longer then 3 hours after the primer has set.

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  

Limitations:

Do not use on wet surfaces or expose to moisture. Keep out of direct sunlight, store on wood pallets at room temperature.

CLEANUP: Use xylol.

RESTRICTIONS: Only recommended for use as primer, not designed as stand alone coating

LIMITATIONS:

• Do not use on wet surfaces or expose to moisture.
• Keep out of direct sunlight, store on wood pallets at room temperature.
• Curing is based on humidity in the air, do not apply when humidity less than 30%
• Be very careful to apply as soon as tack free.  Surface will require sanding for proper bonding in 3-4 hours at 70F-75F
• For best results use a 1/4” or 3/8” nap roller.
• Slab on grade requires moisture barrier
• Substrate temperature must be 5°F above dew point.
• All new concrete must be cured for at least 30 days
• Improper mixing or too thick of an application may result in product failure
• Physical properties listed on this technical data sheet are typical values and not specifications.
• See tab for application instructions.
• See Application tab for limitations of our liability and warranty
