VITCAS Acrylic Coated Glass Fibre Mesh is a multi-purpose reinforcement fabric designed for use in fireplace construction, insulation board systems, heat-resistant adhesives, plaster, render and compatible building applications. Manufactured from woven glass fibres with an alkali-resistant acrylic coating, it provides flexible reinforcement within suitable material layers, helping distribute stresses and reduce surface cracking caused by shrinkage and thermal movement.
Particularly suited to fireplace construction and stove enclosures, the mesh provides reinforcement over compatible insulation boards, heat accumulation boards and uneven masonry substrates. It can be incorporated into suitable VITCAS HB60 Adhesive and VITCAS Heat Resistant Plaster systems according to the relevant installation instructions.
Key Features and Benefits
Acrylic Coated Glass Fibre: Woven reinforcement mesh with improved resistance to moisture, alkaline environments and ageing.
Crack Control: Distributes stresses within plaster, render and adhesive layers, helping reduce surface cracking.
Flexible Reinforcement: Conforms to suitable flat and shaped substrates during application.
Tear Resistance: Durable glass fibre construction provides reinforcement within compatible coating systems.
Board System Compatibility: Suitable for reinforcing appropriate insulation and heat accumulation board installations.
Versatile Application: Designed for use in compatible internal and external plastering and rendering systems.
Applications
Fireplace and Stove Construction: Reinforcing surface layers over suitable fireplace construction and heat-resistant insulation boards.
Heat Accumulation Boards: Reinforcement within compatible adhesive or plaster layers applied over heat storage boards.
VITCAS HB60 Adhesive: Embedding reinforcement mesh in appropriate base coats before subsequent finishing.
Heat Resistant Plaster and Render: Controlling shrinkage and minor movement-related surface cracking in suitable finishes.
General Plaster and Render Repairs: Strengthening suitable surface coatings over prepared masonry and other compatible substrates.
Application Considerations
The mesh should be fully embedded within the specified adhesive, plaster or render layer, with appropriate overlaps at adjoining sheets and reinforcement around corners and changes of substrate where required. Follow the relevant VITCAS product instructions for surface preparation, coating thickness and finishing.
Please note: Glass fibre mesh provides reinforcement within suitable coating systems but is not a structural strengthening material. Its suitability for elevated temperatures depends on the complete plaster or adhesive system, including the temperature limitations of the acrylic coating.
Hi can this glass fibre mesh be used for caravan roller blinds. Thanks
Glass Fibre Mesh is intended primarily for use in fireplaces, stoves and other high temperature applications.
Please what is the weight s m of this mat?
Thank you
It weighs approx. 7 kg.
Is this product sticky so it will stick onto wood
Generally, fiberglass mesh does not go onto wood because it is rated for high temperature applications. But no, it is not self adhesive, when used on pizza ovens, it is stuck using ceramic fibre adhesive.
can i paint it ?
Yes, you could paint it with heat resistant spray paint.
Can this glass fibre mesh can be used for skim coat please
Yes, glass fibre mesh can be used as a skim coat.
Please, mind that only logged in users can submit questions
How does this mesh help prevent cracks in plaster?
Answer
The glass fibre mesh reinforces plaster and render, helping to distribute stresses caused by thermal expansion, settlement, shrinkage and structural movement. Its flexible acrylic-coated construction allows it to adapt to movement while supporting the surrounding material. It should be incorporated into a suitable plaster or adhesive system rather than applied as a standalone surface covering.
Question
Can this glass fibre mesh be used outdoors?
Answer
Yes. The mesh is suitable for both internal and external applications. Its acrylic resin coating provides resistance to moisture, alkaline substances and ageing, making it suitable for reinforcing external renders and insulation finishing systems. The surrounding adhesive, plaster or render must also be appropriate for the substrate and the installation conditions.
Question
Is the mesh suitable for fireplace construction?
Answer
Yes. VITCAS Glass Fibre Mesh can reinforce systems incorporating insulation boards and heat accumulation boards in fireplace construction. It helps strengthen the applied adhesive or plaster and reduce cracking caused by movement or drying. The mesh itself does not replace the correct boards, adhesives or heat-resistant finishing materials required for the fireplace system.
Question
Can it be used with VITCAS HB60 and HRP Heat Resistant Plaster?
Answer
Yes. The mesh is specifically suitable for reinforcing VITCAS HB60 Adhesive and VITCAS HRP Heat Resistant Plaster. It provides structural support within the applied material and helps reduce cracking as the system dries or experiences movement. Ensure the selected adhesive or plaster is suitable for the boards, masonry or other substrate being covered.
Question
Can this mesh reinforce concrete and screed applications?
Answer
The mesh is suitable for reinforcing concrete, screeds and plaster in applications where additional resistance to cracking is required. It can help manage stresses caused by movement, settling or shrinkage. Suitability still depends on the construction system, substrate and installation design, so project-specific structural requirements should be confirmed before use.
Question
Is the mesh suitable for tile adhesive and mosaics?
Answer
Yes. It can be used to reinforce tile adhesive and mosaic applications, helping to improve stability and reduce damage caused by movement. The mesh must be used as part of a compatible adhesive system and is not a substitute for correct substrate preparation. Confirm that the chosen adhesive is suitable for the tiles, surface and service conditions.
