WANSHIELD®62209 Solvent-Free Epoxy Topcoat for Floor Coating

Physical & Chemical Properties

Note: Data provided are typical test values and may vary slightly under different environmental conditions. These specifications are not legally binding.

Construction Requirements

• Concrete strength ≥C25; the flatness should meet the requirement of a 2m alignment ruler with an error within 3mm.
• 28-day curing period required before application to achieve the best results.
• Ambient temperature: 5–35°C (avoid application below 5°C). as it may affect the project quality and the strength of the cured paint film.
• Substrate moisture ≤5%; ambient humidity ≤80%. Otherwise, problems such as blistering may occur, affecting the appearance.
• Ensure dust-free and ventilated environment (avoid strong airflow).

2. Surface Treatment:

• • Grind the substrate to remove contaminants, loose layers, and create a rough surface for enhanced adhesion.

3. Primer Application:

• Use WANSHIELD®62201 Solvent-Free Epoxy Primer or WANSHIELD®62305 Universal Epoxy Primer.

• Apply via trowel or roller (0.15–0.25 kg/m²).

• Ensure no missed coating areas and avoid over – coating. If necessary, apply a second coat of primer or repair the missed coating areas.

4. Intermediate Mortar Layer:

• • After primer curing, mix WANSHIELD®62208 Solvent-Free Epoxy Intermediate Coating or WANSHIELD®62306 Universal Intermediate Coating (A:B ratio as specified) with 80–120 mesh quartz sand. Apply evenly via trowel.

5. Intermediate Putty Layer:

• • Since the surface of the intermediate mortar layer is generally rough, it is necessary to apply putty to level the construction substrate and fill the gaps to ensure a flat surface for the topcoat and a good decorative effect. After mortar layer curing, mix the intermediate coating with quartz powder or putty. Fill gaps and level the surface.

6. Topcoat Application:

• • Mix WANSHIELD®62209 components (A:B=20:4.5 by weight) thoroughly using a high-speed mixer.

  • Pour onto the floor and spread with a trowel, ensuring uniform thickness. Pay attention to preventing material leakage and accumulation.

Construction Parameters

• Mixing ratio (by weight): A:B = 20:4.5.

• Pot life (25°C): 1.5 hours after mixing (1 hour after pouring). The higher the temperature, the shorter the pot life. Construction is generally not recommended when the ambient temperature during construction is higher than 35°C.

• Diluent: Not allowed.

• Recoat interval: 24 hours under standard conditions (25°C, 60% humidity).

Note: Drying time varies with temperature, humidity, film thickness, and ventilation. Higher temperatures shorten drying time.

Before formal project construction, the buyer must conduct tests in an environment consistent with the construction conditions to ensure the reliability of the coating system for the specific project. Formal construction is regarded as the buyer’s recognition of the product’s performance inspection. If the above operations are not followed, all responsibilities shall be borne by the buyer.
