  • Clean

  • Dry

  • Free of wax, oil, dust, grease, or contaminants

• Always prepare a sample or test area to confirm:

  • Compatibility

  • Final appearance

  • Desired performance

Mixing Instructions

• Do not add water

Full Container Mixing

1. Shake the base component well

2. Add the entire hardener to the base

3. Replace lid and shake vigorously until fully mixed

Partial Mixing

Coverage Rates

• 500–600 sq. ft. per gallon per coat

• Coverage may vary depending on cork porosity and surface texture

Drying & Curing Times

• Recoat after: 2–3 hours

• Light foot traffic: after 12 hours

• Furniture placement: after 3 days

• Homes with active dogs: recommended after 5 days

• Full cure: 3 days

Recommended Procedure for Cork Floors

General Guidelines

• Seal cork only after adhesive has fully cured
  (24 hours)

• Apply a maximum of 2 coats per day

Untreated / Natural Cork Flooring or Cork Tiles

1. Apply three total coats of LOBA 2K Supra AT

2. First coat:

   • Roll evenly

   • Allow to dry 2–4 hours

3. Second coat:

   • Apply evenly

   • Allow to dry overnight
     (This reduces the risk of cork granule swelling)

4. Intermediate sanding:

   • Use 180–220 grit perforated pad

   • Lightly sand to remove grain raise

   • Vacuum thoroughly

   • Tack the surface using a clean microfiber mop pad, lightly dampened with water

5. Apply final coat evenly

Prefinished Cork Flooring or Tiles

• Follow recommendations provided by the cork manufacturer

• If recoating is approved:

  • Lightly sand the surface

  • Apply 1–2 coats of LOBA 2K Supra AT

• Ensure proper adhesion through testing before full application

Best Practices for Optimal Results

• Maintain consistent temperature and airflow

• Work methodically to maintain a wet edge

• Avoid over-rolling

• Clean tools immediately after use

• Protect the surface from moisture during curing

Final Notes

LOBA 2K Supra AT provides a durable, professional-grade finish that preserves cork’s natural warmth, elasticity, and appearance. Correct preparation, mixing, and application are essential for long-term performance—especially on cork surfaces, which are more porous than traditional hardwood.
