Fibreglass mesh tape is a robust reinforcement solution predominantly used when applying plaster to fibreboard or similar lightweight boards. It’s designed to provide exceptional adhesion and stability, preventing cracking and ensuring a long-lasting finish. This particular mesh tape offers superior strength compared to traditional paper tapes due to its fiberglass construction, making it ideal for areas subject to movement or impact.
When used with plaster, the mesh tape creates an incredibly strong bond between the board and the plaster layer. The mesh’s interwoven structure allows the plaster to fully embed itself within the fibres, dramatically increasing resistance to delamination. This is particularly beneficial when skimming walls or applying decorative plasters where a high level of structural integrity is required.
This fiberglass mesh tape is compatible with both cement-based and gypsum plasters. It's available in various widths to suit different application needs and provides excellent support for joints and corners, contributing to a professional-looking plastering job. Ensure you use appropriate bonding additives as recommended by your chosen plaster manufacturer.

FAQ
What kind of plaster is this mesh tape best suited for?+
This fiberglass mesh tape works exceptionally well with cement-based plasters and gypsum plasters, offering a strong bond in both. However, for optimal performance, consult the plaster manufacturer's recommendations regarding bonding additives – some plasters benefit from specific additions when using mesh reinforcement.
How do I prepare the surface before applying the tape?+
Surface preparation is crucial. Ensure the fibreboard or board you are plastering is clean, dry and free of loose particles. Lightly sand any rough edges to promote adhesion. A primer specifically designed for fibreboard can further improve bonding.
What width mesh tape should I buy?+
The ideal width depends on your application. Wider tapes (e.g., 150mm) are suitable for larger areas and corners, while narrower tapes (e.g., 75mm) are better for detailing and small repairs. Consider the size of the joint you're reinforcing.
Do I need to apply a bonding agent?+
While not always essential with gypsum plasters, using a bonding agent is highly recommended when working with cement-based plasters and this mesh tape. A bonding agent increases adhesion and helps prevent the plaster from pulling away from the tape.
How much tape do I need for a standard wall?+
This depends on the wall's size and complexity. Measure the total length of all joints and corners, then add at least 20% extra to account for overlaps and waste. A general guideline is 1-2 rolls per standard room.
Can I cut the mesh tape easily?+
Yes, you can cut fiberglass mesh tape with a sharp utility knife or scissors. Score the tape firmly before snapping it along the desired line. Use a cutting mat to protect your work surface and avoid damaging the blade.
Is this tape suitable for external plastering?+
While usable externally, consider the weather conditions. The fiberglass mesh tape is generally robust but prolonged exposure to harsh weather can degrade the adhesive properties. Ensure adequate protection during application and curing.
How should I apply the tape to the board?+
Apply the tape directly onto the fibreboard or board surface, ensuring it’s fully adhered. Use a tacking knife to press firmly along its length, working from one end to the other. Avoid stretching the mesh tape during application as this could compromise its strength.
What happens if the plaster cracks after applying the tape?+
Cracking can occur with any plastering technique. However, using fiberglass mesh tape significantly reduces the risk by providing superior reinforcement. Ensure proper surface preparation and adequate bonding to minimize potential issues.
Does this mesh tape affect the breathability of the plastered wall?+
Generally, fiberglass mesh tape has a minimal impact on the breathability of a plastered wall if applied correctly. However, ensure you don't cover the entire surface with too many layers of plaster to maintain some degree of moisture regulation.
