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.
