(Cork Flooring & Cork Tiles)

Before use, read and understand all label instructions and Safety Data Sheets (SDS).
For technical assistance, contact LOBA-WAKOL Technical Service: 1-800-230-6456.

Approved Application Tools

• Roller: High-quality microfiber roller only

• Nap size: 8–12 mm (3/8”–1/2”)

• No substitutes – incorrect rollers may cause lap marks, bubbles, or uneven sheen

Environmental & Site Conditions (UPDATED)

• Temperature: 18–27 °C (65–80 °F)

• Relative humidity: 35–75% RH

• HVAC systems must be fully operational before, during, and after application

• Product must be:

  • Stored indoors

  • Protected from freezing

  • Acclimated to jobsite temperature before use

⚠️ Do not apply below 13 °C (55 °F)
⚠️ Always maintain adequate ventilation

Cork Installation Waiting Periods (UPDATED)

Glue-Down Cork Tiles

• Allow adhesive to fully cure – minimum 24 hours

• Follow adhesive manufacturer’s instructions exactly

Floating Cork Flooring

• Floor may be finished once installed

• Recommended rest period: 24–72 hours

• This resting period allows:

  • Identification of installation errors

  • Correction before finishing

• All installation issues must be corrected before coating

Protect Product From Freezing

• Storage range: 5–28 °C (42–85 °F)

• Products exposed to freezing temperatures must not be used

Refinishing Existing Cork Floors (If Applicable)

This step applies only to cork floors that have been in use for years.

• Clean thoroughly using household-strength TSP (trisodium phosphate)

• Rinse with clean water multiple times

• No residue may remain

• Allow floor to dry completely before proceeding

Abrading Factory-Finished Cork (UPDATED GRIT)

LOBA 2K Supra AT may be applied over factory-finished cork when properly abraded.

• Light abrasion only – do NOT remove the factory finish

• Recommended abrasives:

  • 180–220 grit screen or perforated pad

  • Fine maroon pad (equivalent)

• Objective:

  • Create micro-abrasion for adhesion

  • No visible sanding marks

• Always test on a spare plank or tile first

Cleaning After Abrasion

1. Vacuum thoroughly

2. Damp wipe using:

   • Clean microfiber mop

   • Water only (lightly damp, not wet)

3. Allow 1–2 hours drying time before coating

Mixing Instructions (UPDATED & CURRENT)

Pot Life

• Approximately 2 hours after mixing

Full Container Mixing

1. Shake base container thoroughly

2. Add entire hardener to base

3. Replace lid and shake vigorously for 60 seconds

4. Product is ready to use immediately

Mixing Smaller Quantities

• Mixing ratio: 10 parts base : 1 part hardener

• Use a scale or LOBA mixing container for accuracy

• Shake mixed material for 60 seconds

🚫 Do not thin
🚫 Do not add water

Application Method

Preferred Method

• Direct-pour onto floor and spread with saturated roller
  OR

• Use a clean painter’s tray (rinsed with water and fully dried)

Key Application Rules

• Roller should be fully saturated but not dripping

• Maintain a wet working edge

• Do not re-roll areas older than 10 minutes

• Avoid puddles, streaks, and over-working the finish

Coverage

• 500–600 sq. ft. per gallon per coat

• Coverage varies depending on cork porosity

Number of Coats & Timing (UPDATED)

• Maximum coats per day: 2

• Time between coats: 2–3 hours minimum

• If drying is delayed, wait until the surface is completely dry before recoating

Drying, Traffic & Cure Times (UPDATED)

• Light foot traffic (socks only): ~5 hours

• Normal foot traffic: ~12 hours

• Furniture placement: after 3 days

• Full cure: 3 days

• Active dogs: recommended after 5 days

🚫 No rugs, furniture, pets, or children during cure period
Even if the floor appears dry, it may not be fully cured

First Damp Cleaning

• Earliest: 5 days after final coat

• Use:

  • Water only or

  • pH-neutral hardwood floor cleaner

• Do not wet-mop

Important Warnings

⚠️ Short working time:
Water-based polyurethanes have a ~10-minute working edge.

If lap marks occur:

• Stop application

• Allow floor to dry

• Contact your LOBA-WAKOL or flooring specialist before proceeding

⚠️ If the floor shows:

• Buckling

• Lipping

• Separation
  Do NOT apply finish – investigate installation or moisture issues first

Tool Cleaning

Clean all tools and equipment immediately after use with clean water.

Floor Care & Maintenance

• Clean the floor with a damp cloth or mop only after the finish has fully cured.

• Do not clean with water or detergents during the first week following application.

• After one week, begin routine maintenance using Hardwood Floor Cleaner.

• Place walk-off mats at all entryways to help minimize dirt and grit.

• Sweep or vacuum daily to remove abrasive particles.

• Damp-wipe as needed using Hardwood Floor Cleaner.

• Install felt pads under furniture legs and appliances.

• Move furniture and heavy appliances carefully to prevent surface damage.

Plasticizer-Containing Materials

Products containing plasticizers—such as carpet padding, furniture pads, chair casters, elastic adhesives, and similar materials—may cause softening or discoloration of the finish. Avoid prolonged or direct contact with these materials.

Cure Time Considerations

Drying and curing times are based on ideal conditions:

• 68°F (20°C)

• 50% relative humidity

• Recommended application thickness

Curing time may be extended by:

• Poor ventilation

• High humidity

• Low temperatures

• Excessive finish build

Do not cover floors, reinstall carpets or rugs, or clean with a damp cloth or mop until full cure has been achieved.

Intermediate Sanding

• When applying multiple coats, additional coats may be applied within 24 hours without intermediate sanding.

• If more than 24 hours pass between coats, intermediate sanding is required.

• Light sanding before the final coat is recommended to achieve a smoother, more uniform surface.

• Remove all sanding dust thoroughly before applying additional coats.

Final Note

LOBA 2K Supra AT is a professional, high-performance finish. Cork flooring is more porous and reactive than traditional hardwood, making correct timing, sanding grit, and climate control critical to success.

When in doubt, test first and contact LOBA-WAKOL Technical Service before proceeding.
