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.

4 Types of GRC Screws and Their Functions

Have you ever experienced cracked GRC boards while drilling, or screw heads that protrude and are difficult to cover with compound during finishing? These common issues often occur when using regular screws or those that are not suited to the specific thickness of the board.

Choosing the wrong screws does not only compromise aesthetics but also risks reducing the structural integrity of GRC boards in ceiling, wall, floor, and decking applications. Since GRC boards come in various sizes and thicknesses, GRC board accessories—including specialized screws—are available in multiple dimensions to ensure a sturdy and long-lasting installation.

To ensure optimal locking and a perfect flush finish, GRC board offers four types of specialized screws. Here is a complete guide to their functions:

4 mm GRC Screw

This screw is specifically engineered for installing 4 mm thick GRC boards, which are commonly used for economical ceiling applications. Due to the board's thin profile, specific technical requirements are needed to prevent the edges from cracking.

• Key Features: It features a thinner head and a single-thread system, allowing it to grip the frame firmly without putting excessive pressure on the delicate surface of the board.

5–8 mm GRC Screw

Designed for medium-thickness GRC boards (5–8 mm), these screws are the standard for wall and sturdier ceiling partitions.

• Key Features: The head is equipped with fins and a double-thread system. This design is intended to "scrape" the board as it enters, allowing the screw head to be easily countersunk without damaging the surrounding surface.
• Note: These are not recommended for 4 mm boards as the size is too large and may cause breakage.

9–20 mm GRC Screws

These screws are used for heavy-duty GRC boards with a thickness of 9 mm to 15 mm. Generally used for board applications such as partition walls, floors, decks, and outdoor cladding that require high stability. Using standard screws for this thickness is ineffective. These specialized screws provide the maximum fastening power needed to support the weight and pressure typically found in flooring structures.

• Key Features: They provide a deeper reach and stronger pull-out resistance, ensuring the panels stay secure even in high-traffic or outdoor environments.

Using the correct screw size is the key to a smooth, secure, and professional result. Original GRC board accessories are designed to speed up the installation process through their practical countersunk feature, saving you time and effort during the finishing stage.

Don't let the wrong hardware ruin your project. Ensure your installation is sturdy by matching your screw type to your board thickness.
