The Function and How to Use GRC Tape in Construction

Creating walls or ceilings that look seamless with no visible joints is every building owner’s dream. This requires high-quality materials and supporting accessories for the jointing system or for sealing gaps. This is where GRC tape particularly when applied to GRC boards becomes essential.

GRC Tape is one of the accessories produced by the GRC board brand. It is specifically designed to reinforce the joints between panels, ensuring the final finish from the joint to the paint looks flawless. Additionally, it serves as an intermediary between the surface and GRC Putty Flex Plus. Check out the detailed guide below on the functions and proper use of GRC boards.

What is GRC Tape?

GRC Tape is a specialized joining tape made of gauze fabric with stronger fibers despite its thinness. Compared to regular duct tape, GRC Tape has pores that allow GRC Putty Flex Plus to penetrate, resulting in a stronger bond between GRC boards.

Functions of GRC Tape in Construction

Bonding and Reinforcing Joints: Enhances the bonding strength between GRC Putty Flex Plus and the board surface.

Preventing Hairline Cracks: GRC Tape can withstand joint shifting caused by structural movement due to vibrations.

Creating a Smooth Surface: Maximizes the smoothness of the joint surface for the painting process.

How to Use GRC Tape in Construction

For optimal results, follow these steps:

1. Clean the Joint Area: Use a dry brush to remove dust or cement residue from the sloped edges of the boards.

2. First Layer of GRC Putty Flex Plus: Apply a sufficient amount of GRC Putty Flex Plus to fill the joint gap. Ensure it is filled tightly.

3. Applying GRC Tape: Apply the GRC Tape precisely in the center of the joint while the GRC Putty Flex Plus is still wet. Press gently to ensure the tape adheres perfectly.

4. Second Layer of GRC Putty Flex Plus: Cover the surface of the GRC Tape with a second layer of GRC Putty Flex Plus. Spread the application to cover the sloped edges of the board.

5. Finishing and Sanding: Once the GRC Putty Flex Plus is fully dry or touch-dry, sand the surface using fine-grit sandpaper until it is smooth. The area is now ready for painting.

Precise and correct application of GRC tape to GRC boards is key to ensuring that the board joints hold up over time. Make sure you use genuine GRC Board products to ensure long-lasting material quality. Consult with the GRC Board expert team now by clicking the WhatsApp feature on this website. 

The Best Types of Paint for GRC Boards

GRC boards are renowned for their durability, making them a top choice for ceilings and walls. However, a common challenge many face is paint peeling or an uneven finish.

This typically occurs because cement boards have different absorption rates and alkalinity levels compared to traditional brick walls. Therefore, selecting the right paint and application method is crucial for a flawless result.

1. Apply a Dedicated Primer

The most frequent mistake is applying topcoat paint directly onto the board without a primer. Because GRC boards are cement-based, they have a high pH level that can react with paint, causing it to flake. We recommend using a water-based, alkali-resistant primer to seal the surface and ensure better adhesion for the subsequent layers.

2. Use 100% Acrylic Emulsion for Exteriors

For GRC boards used on facades or outdoor areas, it is essential to use 100% acrylic emulsion exterior paint. This type of paint is specifically engineered to resist fading from intense UV exposure and heavy rain. Its flexibility also allows it to withstand the natural expansion and contraction of the boards due to temperature changes.

3. Specialized Paint for Wood-Patterned GRC

For the GRC Plank Series, we recommend using Fiber Cement Paint or specialized wood stains designed for cementitious materials. These products are formulated to penetrate deep into the pores of the board, accentuating the natural wood grain texture while providing a robust shield against mold and mildew.

Conclusion

Investing in paint specifically formulated for GRC boards is far more cost-effective than dealing with the labor and costs of frequent repainting. Proper preparation and the right products will ensure your home stays vibrant and protected for years.

Shiplap Walls Using GRC Board for Farmhouse Style Homes

Modern rustic and farmhouse-style homes are currently in high demand. One of the defining elements of this design aesthetic is the shiplap wall.

Traditionally, shiplap is synonymous with natural wood planks. However, in tropical climates like Indonesia, using natural wood carries a high risk of termite infestation and decay caused by high humidity. To maintain the shiplap aesthetic without the maintenance headaches, GRC Board offers a superior alternative that is termite-proof, mold-resistant, and moisture-proof.

Utilizing fiber cement boards like GRC Board provides dual benefits. First, the surface texture beautifully mimics natural wood grain. For shiplap applications, homeowners can choose from the GRC Plank Series, which features exquisite motifs such as GRC Rosewood Plank, GRC Mahogany Plank, and GRC Timber Plank. Second, it combines the warm, organic look of wood with the structural durability of cement. The GRC Plank Series is engineered for longevity, ensuring your home stays stunning for years to come.

Inspiration for GRC Board Shiplap Applications

1. Living & Family Rooms

Use the GRC Plank Series as an accent wall to create a focal point. Painting the planks in a creamy beige tone will evoke a spacious, warm, and clean atmosphere.

2. Facades & Exterior Areas

For a calm and modern curb appeal, install the GRC Plank Series horizontally on your home's exterior. An off-white finish will provide a crisp, timeless look that enhances the farmhouse vibe.

Achieving a farmhouse-style home is now easier and more cost-effective with GRC Board. By choosing GRC materials, your shiplap walls will be stronger, more aesthetic, and highly durable.
