Description

Glass Fiber Grid Joint Tape | Anti-crack Reinforcement・Self-adhesive and Easy to Apply・Special for Gypsum Board Joints

Product Overview

Glass Fiber Grid Joint Tape, which is made ofHigh-strength glass fiber strands woven into a mesh substrateThis special wall reinforcement tape is made with self-adhesive pressure-sensitive adhesive. It is designed for strengthening joints in gypsum board, cracks in walls, and corners. It distributes stress through a grid structure to prevent cracks and peeling at the root. It also comes with a back adhesive for construction without nails, suitable for home decoration, industrial construction, and maintenance. It is an essential auxiliary material for wall construction.

Core Attributes (Hardcore Parameters)

Parameter item	Details
Core Material	Medium alkali / non-alkali glass fiber yarn + self-adhesive acrylate pressure-sensitive adhesive

Core Advantages (Why Choose It)

High tensile grid, prevents cracking at the source

Glass fiber warp and weft woven grid structure, high strength and good toughness, can effectively distribute the stress of the joints and cracks in gypsum boards, prevent the cracking and peeling caused by wall contraction and vibration in the later period, and the service life of the wall surface is more durable.

Self-adhesive and nail-free design, efficient and hassle-free construction

Equipped with high-adhesive pressure-sensitive glue, it can be directly pasted after peeling off the backing tape, requiring no additional brush glue or waiting for curing. It can be operated by one person, significantly improving construction efficiency, and it is easy for beginners to master, saving labor costs.

Alkali-resistant and moisture-proof, stable in humid environments.

Glass fiber base material is resistant to alkalis and moisture, paired with water-proof backing adhesive, it can also be used on damp walls such as bathrooms and kitchens. It is less prone to mold, delamination, and deformation, and is compatible with a variety of wall construction environments.

Compatible with multiple materials, adaptable to the entire construction process

The surface mesh structure can be closely integrated with materials such as putty, gypsum, latex paint, etc., making it less likely to bubble or peel off. Whether it is for repairing joints in gypsum boards, cracks in walls, or reinforcing corners, it can be perfectly adapted.

Multiple specifications available, with custom service support.

Multiple widths, lengths, and grid densities are available, covering the routine construction needs of home decoration and industrial decoration; simultaneously, it supports custom sizes and printing brand logos, adapting to foreign trade orders and engineering bulk purchases.

15 years factory direct supply, price quality stability

Deeply engaged in the tape industry for 15 years, we have our own glass fiber weaving production line, with strict product quality control. Direct factory sales eliminate the middleman, making our prices more competitive. Large-scale purchases are more cost-effective, and after-sales service is worry-free.

Full-scene application (full coverage adaptation)

Home decoration construction

Gypsum board ceiling / partition joint: Adhered to the joint of the gypsum board, preventing the ceiling from cracking and the wall from splitting in the later stage.

Repair of wall cracks: For cracks in the old house walls and areas where the putty layer has cracked, apply a reinforcing paste and then scrape on a new layer of putty to prevent the recurrence of cracks.

Strengthening corners: Adhering to the corners of the wall and the peripheries of door frames/window frames, enhancing the strength at the corners to prevent knock-offs and cracking.

Work-wear engineering

Office Building / Hotel Decoration: Joint Treatment of Large Area Gypsum Board Partitions and Ceiling, Ensuring That the Engineering Walls Do Not Crack

Refurbishment of old workwear: Repairing cracks and hollow areas in old walls, quickly reinforcing the wall base.

Exterior wall insulation construction: Reinforcing the joints and corners of the insulation layer, enhancing the bonding strength between the insulation layer and the wall surface.

Maintenance and DIY

Local wall patching: When patching nail holes or small areas of damage on the wall, adhere a grid strip to enhance the strength of the base layer.

Installation of Gypsum Line / Decorative Lines: Adhere the lines to the joint of the wall to prevent cracking and peeling in the later period.

Self-built house / B&B construction: Low-cost wall reinforcement solution, enhance wall stability, reduce later maintenance.

Construction Tips

Before pasting, ensure that the wall base is clean, dry, and flat, without oil stains or dust, to avoid affecting the adhesive strength of the backing tape.

Center the tape along the joint or crack of the gypsum board, press gently to discharge air bubbles, and ensure that the tape is tightly adhered to the wall surface.

When constructing the corners of Yin and Yang, you can fold the tape at a 90° angle and paste it along the corner to enhance the reinforcement effect at the corner.

After pasting is completed, apply the putty or plaster again to ensure that the material is fully embedded in the grid, thereby enhancing the bonding strength.

When constructing in humid environments, it is recommended to first perform a damp-proof treatment on the base layer, and then adhere the tape to extend the service life.
