Applying the Product

1. Surface Preparation

Concrete compressive strength should be a minimum of 25 N/mm².
The surface must be clean, dry, and free of oil, dust, or weak layers.
Use specialized chemical and mechanical preparation to clean the surface.
Uneven or damaged floors should be repaired first.
Substrate moisture content must be less than 12%.

2. Application Conditions

Substrate moisture content: <12%
Substrate temperature: +15°C to +39°C
Maximum relative air humidity: 80%
Substrate temperature must be at least 3°C above the dew point.

3. Mixing

Use a slow-speed mixer (approx. 300 rpm).
First, mix Part A for 2-3 minutes to reconstitute any settlement.
Add Part B to Part A and mix for another 2-3 minutes until the color is homogeneous.
Note: Once mixed, this material cannot be resealed for later use.

4. Application

Roller: Apply evenly with a short-hair roller.
Airless Spray: A 20:1 ratio piston pump with a 0.015-inch nozzle may be used. For best results, add up to 5% clean water to aid spray application.

5. Limitations

To achieve a homogeneous color, use materials from the same production batch in one area.
Direct sunlight may cause some discoloration, but this does not influence the coating's performance.

🕒 Curing

Temperature	Walking	Light Traffic	Full Traffic
+10°C	48 h	5 days	15 days
+20°C	24 h	4 days	10 days
+30°C	18 h	1 day	5 days

📦 Storage & Packaging

Packaging: Supplied in 15kg per set.
Storage: 12 months from manufacture date. Must be stored in original packaging, out of sunshine, at temperatures from 20-40°C.

🧼 Cleaning & Maintenance

Equipment Cleaning: Clean tools immediately after use with water.
Surface Maintenance: Allow the coating to cure for at least one week before mechanical cleaning. It can be easily maintained by damp mopping with a neutral cleaner.

⚠️ Safety Precautions

Ensure good ventilation, especially in confined areas. Wear a respirator if necessary.
Always wear gloves and appropriate work clothing.
Keep the area free of flammable liquids and sources of ignition. No smoking.
Consult the Material Safety Data Sheet (MSDS) before handling.
