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 specially designed 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 and 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.

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

Physical and Mechanical Properties

Surface Preparation

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

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

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

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

Mixing Instructions

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. Use within 40 minutes of mixing to ensure workability and consistency.

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.

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.

Cleaning of Tools

Immediately clean all tools and mixing equipment with water after use.
Hardened material can only be removed mechanically.

Storage and Shelf Life

• Store in original unopened bags, in a dry, covered, and well-ventilated area.

• Protect from direct sunlight, rain, and extreme temperatures.

• Shelf life: 18 months from the date of manufacture.

Health & Safety Information

• Avoid inhalation of dust during mixing.

• Use protective gloves, goggles, and a dust mask.

• In case of skin or eye contact, rinse immediately with plenty of water.

• Refer to the Material Safety Data Sheet (MSDS) for complete safety instructions.

Packaging

• Available Pack Sizes: 25 kg multilayer moisture-resistant bags.

• Color Options: Grey and Light Grey.

Important Notes

• Do not apply on painted, gypsum, or excessively porous surfaces.

• Avoid mixing with any additives, cement, or sand.

• Application on extremely dry or hot surfaces may cause dusting—ensure proper pre-wetting.

• Always perform a compatibility test before applying paints or protective coatings.

• For best results, follow PC-WC’s recommended application guidelines.

Typical Coverage

Coverage depends on substrate roughness and thickness.
On average, 1 mm thickness covers 18–20 m² per 25 kg bag.
