What Is AC3 Floating Laminate Flooring?

AC3 floating laminate flooring refers to a laminate floor with an AC3 abrasion class rating that is installed using a floating system—i.e., it is not nailed or glued to the subfloor but rather "floats" on top of underlayment using a click-lock mechanism. The AC3 rating signifies suitability for moderate residential and light commercial traffic, per EN 13329 European standards.

🧪 AC Rating Definition: "AC" (Abrasion Criteria) ratings range from AC1 to AC5, with AC3 indicating durability for:

• Residential use in high-traffic areas (living rooms, hallways)

• Light commercial use (hotel rooms, small offices)

Installation Guidelines

📦 Acclimatization

Let the flooring acclimate for 48–72 hours in the installation room at stable temperature and humidity.

📏 Subfloor Requirements

• Flatness: ≤2 mm over 2 meters

• Moisture: ≤5% for cement, ≤12% for wood

• Clean and dry

🔗 Floating Installation

• Use click-lock system (Valinge®, Uniclic®)

• Lay with 10–12 mm expansion gaps along all walls and fixed objects

• Install underlayment if not pre-attached

🧼 Maintenance

• Damp mop only (never wet mop)

• Use pH-neutral cleaners

• Use furniture pads to prevent surface scratching

Common Mistakes to Avoid

1. ❌ Installing without acclimation — may cause buckling or gapping

2. ❌ Wet mopping — can cause swelling at joints

3. ❌ Inadequate expansion space — leads to edge curling or warping

4. ❌ Wrong room application — avoid in bathrooms, saunas, or high-humidity zones

5. ❌ Poor subfloor prep — compromises lock integrity and causes noise
