When finishing walls and ceilings, choosing the right tape helps prevent cracks and ensures a smooth surface. Fibreglass tape and paper tape are two common options, each with different strengths. Fibreglass tape is strong and easy to use, while paper tape gives a smoother and cleaner finish.
Fibreglass tape is a narrow, woven strip made from glass fibre yarns known for their exceptional strength, durability, and resistance to heat and corrosion. This versatile material is commonly used in industries such as construction, electrical insulation, and composite manufacturing. The tape is typically woven in plain or twill patterns and can be coated with materials like silicone, PTFE, or adhesive backings to enhance performance in specific applications.
Fibreglass tapes are designed to withstand heavy loads and tension without stretching or tearing. This makes them ideal for structural reinforcement and applications requiring long-term dimensional stability.
They can typically endure continuous temperatures up to 550°C (1022°F) and short-term exposure to even higher temperatures, making them suitable for thermal insulation, furnace sealing, and fire protection.
Unlike metal tapes, fibreglass tape does not rust or corrode. It maintains its integrity when exposed to moisture, acids, alkalis, and other harsh chemicals, ensuring long-lasting performance in industrial environments.
The non-conductive nature of fibreglass makes it a reliable material for insulating electrical wires, motors, and transformers, protecting against short circuits and overheating.
Despite its strength, fibreglass tape is lightweight and easy to handle. Its flexibility allows it to conform to irregular shapes, corners, and contours without losing its reinforcing properties.
The tape maintains its shape even under fluctuating temperatures and humidity levels, providing consistent performance over time without shrinking or expanding.
Paper tapes are adhesive-backed tapes made from kraft paper or similar paper materials, designed for sealing, packaging, masking, or labeling applications. Depending on the type, paper tapes can be water-activated (gummed) or pressure-sensitive. Water-activated paper tape has a starch-based adhesive that forms a strong bond when moistened, while pressure-sensitive versions use natural or synthetic rubber adhesives for instant adhesion without water.
One of the biggest advantages of paper tape is its sustainability. Made primarily from natural kraft paper, it is biodegradable and can be recycled along with cardboard boxes, making it an environmentally responsible choice.
Water-activated and pressure-sensitive paper tapes provide excellent bonding strength to a variety of surfaces such as cardboard, paperboard, and kraft paper. Once applied, the tape forms a secure, tamper-evident seal ideal for shipping and storage.
Paper tapes have a smooth, matte finish that allows easy printing, labeling, or handwriting. This feature is especially useful for branding, identification, or instructional markings on packaging.
High-quality kraft paper tapes maintain adhesion even under temperature fluctuations and moderate humidity. Some variants are reinforced with fiberglass or synthetic fibers to improve strength and performance in harsh conditions.
Unlike plastic tapes that require scissors or dispensers, paper tapes can be easily torn by hand, making them quick and convenient to use during packaging or sealing tasks.
Paper tape does not stretch or generate static electricity like plastic tape, ensuring a clean, precise application. This makes it ideal for applications that demand neat edges or easy handling.
When finishing drywall joints or repairing wall and ceiling cracks, choosing between paper tape and fibreglass tape is crucial for achieving a smooth, durable, and long-lasting result. Understanding these differences helps professionals and DIY users select the right tape for specific projects.
Paper Tape: Made from high-quality kraft paper, often with a slightly rough texture for better adhesion to joint compound. It usually has a crease down the center to help fold neatly into inside corners.
Fibreglass Tape: Constructed from woven glass fibre mesh, it is strong, flexible, and resistant to mold and moisture. Available in both self-adhesive and non-adhesive versions, it offers easy application and high tensile strength.
Paper Tape: Requires embedding into a layer of joint compound, making it slightly more technique-sensitive. The surface must be smooth and bubble-free, and it takes some skill to apply evenly. However, it’s preferred by many professionals for its strong bond once properly embedded.
Fibreglass Tape: Easier and faster to apply, especially the self-adhesive type, which sticks directly to drywall joints without a base coat of compound. This makes it ideal for quick repairs and DIY use.
Paper Tape: Provides excellent crack resistance when properly installed because it bonds tightly with joint compound, creating a rigid reinforcement layer. It’s especially effective for tapered joints and inside corners.
Fibreglass Tape: Offers high tensile strength and flexibility but is slightly more prone to cracks in joints if not fully embedded in compound. It performs best in flat seams or repair areas, where its flexibility can absorb minor structural movement.
Paper Tape: Can absorb moisture and is not recommended for damp or humid areas like bathrooms or basements unless sealed with a waterproof finish.
Fibreglass Tape: Naturally resistant to moisture, mildew, and mold, making it a better choice for high-humidity environments and water-prone areas.
Paper Tape: When applied correctly, it offers long-lasting durability and holds up well against cracking or peeling over time.
Fibreglass Tape: Extremely durable in moist or unstable conditions but may not achieve the same perfectly smooth finish as paper tape in high-end interior work.
Both tapes work well for wall and ceiling finishing. Fibreglass tape is better for quick jobs and damp areas, while paper tape is ideal for getting a smooth, professional look. Choosing the right one depends on your project needs and the finish you want.

Contact NowWhat is the main difference between fibreglass tape and paper tape?
The key difference lies in their material and application method. Fibreglass tape is made from a woven glass fibre mesh and often comes with a self-adhesive backing, making it easy to apply directly to drywall joints. Paper tape, on the other hand, is made from kraft paper and needs to be embedded in a layer of joint compound.
Which tape provides a smoother finish on walls and ceilings?
Paper tape delivers a smoother, more seamless surface because it fully blends into the joint compound. Once sanded and painted, it leaves no visible texture. Fibreglass tape, however, has a mesh texture that can sometimes show through the compound if not properly covered, requiring extra coats for a perfect finish.
Is fibreglass tape stronger than paper tape?
In terms of tensile strength and resistance to movement, fibreglass tape is generally stronger because of its woven mesh construction. It can withstand more stress and movement in the wall without tearing. However, when it comes to crack prevention, paper tape performs better since it bonds tightly with the compound, forming a rigid and stable joint.
Which tape lasts longer over time?
When applied properly, paper tape typically provides better long-term crack resistance in stable, dry environments. Fibreglass tape lasts longer in humid or unstable conditions because it doesn’t deteriorate or absorb moisture. The overall durability depends on the quality of installation and the environmental conditions.
What type of joint compound works best with each tape?
Paper tape works best with all-purpose or setting-type joint compounds since it needs to be fully embedded in the mud. Fibreglass tape, especially the self-adhesive kind, can be applied directly on the drywall surface and then covered with joint compound. For the strongest results, ensure proper drying and at least two coats of compound for both types.
How do I choose the right tape for my project?
Choose fibreglass tape if you need quick application, moisture resistance, or are working in a high-humidity environment. Opt for paper tape if you want a flawless, smooth finish in dry indoor spaces. For the best results, match the tape to your wall condition, skill level, and desired appearance.
