This manual provides detailed instructions for the proper use and application of the Ardex 8+9 system.

2. Maklumat Keselamatan

Always prioritize safety when working with construction materials. Read and understand all safety data sheets (SDS) before use. The following precautions are recommended:

• Alat Pelindung Diri (PPE): Wear appropriate PPE, including safety glasses, chemical-resistant gloves, and a dust mask or respirator, especially during mixing.
• Pengudaraan: Ensure adequate ventilation in the work area to minimize inhalation of dust and fumes.
• Sentuhan Kulit dan Mata: Elakkan sentuhan langsung dengan kulit dan mata. Sekiranya terkena, bilas segera dengan air yang banyak dan dapatkan rawatan perubatan jika kerengsaan berterusan.
• Pengingesan: Jangan termakan. Jika tertelan, jangan paksa muntah. Dapatkan rawatan perubatan segera.
• Storan: Store components in a cool, dry place, away from direct sunlight and extreme temperatures. Keep out of reach of children and pets.
• Pelupusan: Dispose of unused material and empty containers according to local regulations.

• Waterproofing commercial and residential bathrooms, showers, and kitchens.
• Protecting floors and walls from water infiltration.
• Providing crack isolation up to 1/8 inch (3 mm).
• Use on concrete balconies, patios, and swimming pools.
• Serving as a shower pan liner.
• Preventing efflorescence from the substrate.

4. Persediaan dan Persediaan

4.1 Penyediaan Permukaan

Proper surface preparation is critical for optimal performance. Surfaces must be:

• Bersih: Free from dust, dirt, oil, grease, paint, curing compounds, and other contaminants.
• kering: Ensure the substrate is completely dry before application.
• Bunyi Secara Struktur: Substrates must be solid, stable, and capable of supporting the intended load. Repair any damaged or loose areas prior to application.
• Licin: Rough or uneven surfaces should be leveled to ensure uniform application and coverage.

4.2 Mixing Instructions

The Ardex 8+9 components must be mixed thoroughly to achieve the desired consistency and performance.

1. Pour the entire contents of Ardex 8 (liquid) into a clean mixing container.
2. Gradually add the entire contents of Ardex 9 (powder) to the liquid while continuously mixing with a low-speed drill (300-600 rpm) and a mixing paddle.
3. Mix for 3-5 minutes until a smooth, lump-free, homogeneous consistency is achieved. Avoid over-mixing, which can entrain air.
4. Allow the mixture to stand for 2-3 minutes, then remix briefly for 30 seconds.
5. The working time for the mixed material is approximately 30-45 minutes at 70°F (21°C). Adjust for temperature and humidity.

5. Operating and Application Instructions

5.1 Kaedah Permohonan

Apply the mixed Ardex 8+9 using a brush, roller, or trowel. Ensure complete and uniform coverage.

1. Kot Pertama: Apply a thin, even first coat to the prepared substrate. Ensure all areas are covered, paying close attention to corners, seams, and penetrations.
2. Masa Pengeringan: Allow the first coat to dry for approximately 1-2 hours, or until it is tack-free and can be walked on without damage. Drying times may vary based on temperature and humidity.
3. Kot Kedua: Apply a second coat perpendicular to the first coat to ensure full coverage and build the required thickness.
4. Pengasingan Retak: For crack isolation up to 1/8 inch (3 mm), ensure the membrane fully bridges the crack with adequate thickness.
5. Liputan: A 100 sq. ft. kit provides approximately 100 sq. ft. of coverage for two coats. Commercial units can cover up to 300 sq. ft.

5.2 Flood Testing

For shower pans and other wet areas, flood testing can be performed after the membrane has fully cured.

• The Ardex 8+9 membrane can be flood tested in as little as 4 hours after the final coat application, under ideal drying conditions.
• Ensure all drains are properly sealed before filling the area with water.
• Observe for any leaks over the recommended testing period (typically 24 hours).

6. Penyelenggaraan

Once cured and tiled, the Ardex 8+9 membrane requires no specific maintenance. Regular cleaning of the tiled surface should be performed according to the tile and grout manufacturer's recommendations. Avoid using harsh chemicals that could degrade grout or sealant materials.

7. Penyelesaian masalah

• Poor Mixing: If the mixture is lumpy or inconsistent, it indicates insufficient mixing. Ensure a low-speed drill with a proper paddle is used and mix for the recommended duration.
• Masa Kerja Singkat: High temperatures or adding too much powder can shorten the working time. Work in cooler conditions if possible, and adhere strictly to the mixing ratio.
• Lekatan yang lemah: This is often due to improper surface preparation. Ensure the substrate is clean, dry, and free of contaminants.
• Pinholes/Bubbles: Can occur from over-mixing (entraining air) or applying too thick a coat. Apply in thin, even coats and avoid excessive agitation during mixing.
• Slow Drying/Curing: Low temperatures, high humidity, or poor ventilation can extend drying times. Ensure adequate airflow and maintain recommended environmental conditions.
