PC-Conrend® FC

Polymer Modified Skim Coat

Premium Finishing Solution for Concrete, Masonry, and Plaster Surfaces

PC-Conrend® FC is a high-performance, polymer-modified cementitious skim coat specifically engineered to eliminate surface imperfections, pinholes, and minor defects on concrete, plaster, mortar, and stone masonry. Its advanced formulation ensures a smooth, durable, and aesthetically refined finish for both interior and exterior applications.

Engineered with precision by PC-WC Global FZ-LLC, this single-component finishing compound provides superior adhesion, flexibility, and workability—making it the ideal choice for architects, contractors, and finishing specialists who demand perfection in every surface.

Key Features & Benefits

• Smooth and Refined Finish: Delivers a fine, uniform surface ideal for painting or decorative coatings.

• High Strength and Durability: Withstands stress and environmental exposure, ensuring long-lasting protection.

• Excellent Adhesion: Bonds strongly to concrete, plaster, and masonry substrates.

• Fast Drying and Easy Application: Saves time on-site with simple mixing—just add clean water.

• Crack Resistance: Formulated to resist cracking when applied correctly and properly cured.

• Temperature Tolerant: Performs well in both hot and humid climates (10°C–40°C).

• Versatile Application: Suitable for vertical, horizontal, and overhead surfaces, including precast concrete panels and exposed concrete finishes.

• Spray or Trowel Application: Can be applied by steel trowel or spray machine for faster coverage.

• Reduced Material Wastage: Adjustable plaster thickness minimizes consumption and cost.

Areas of Application

PC-Conrend® FC is suitable for a wide range of concrete and masonry surface finishing works, including:

• Precast concrete elements (beams, columns, panels).

• Fair-faced concrete and exposed structures.

• Walls and ceilings prior to painting.

• Masonry and plastered surfaces requiring surface correction.

• Repair of honeycombs, pinholes, and small surface voids.

• Architectural concrete finishing and aesthetic restoration.

Physical & Mechanical Properties

Application Instructions

1. Surface Preparation

• Clean the Substrate: Remove dust, oil, grease, loose materials, curing compounds, and coatings that may hinder adhesion.

• Repair Voids and Cracks: Fill cracks and uneven areas using appropriate repair materials before applying PC-Conrend® FC.

• Pre-wetting: Saturate the surface with water for at least 2–4 hours prior to application. The substrate should be damp (SSD condition) but not waterlogged.

• Check Compatibility: Avoid application on painted or gypsum-based surfaces. For unknown substrates, perform a patch test.

2. Mixing

1. Pour 6.5 – 7 liters of clean water into a mixing container for each 25 kg bag.

2. Gradually add PC-Conrend® FC powder while mixing continuously using a slow-speed heavy-duty drill (400–600 rpm) with a paddle attachment.

3. Mix for about 3 minutes until a smooth, lump-free consistency is achieved.

4. Allow the mix to stand for 2–3 minutes, then remix for 15–30 seconds before application.

5. Note: Use within 40 minutes of mixing to ensure workability.

3. Application Procedure

1. Apply the mixed compound using a steel trowel or spray equipment.

2. Firmly press the material into pinholes and imperfections.

3. Allow the surface to partially set before applying the final smooth layer.

4. For a polished finish, lightly sprinkle water and re-trowel using a sponge or steel float.

5. For multi-layer application, ensure the first layer has set but not fully dried before applying the next coat.

4. Curing

Proper curing is essential to achieve optimum strength and adhesion.

• After the final coat, cure the surface using PC-Buildcure® WB or by misting water periodically for 24–48 hours to prevent premature drying and shrinkage cracks.
