The Glass Fibre Mat 300g is a high-strength fibreglass reinforcement material designed for demanding repair, rebuilding and structural strengthening tasks. It is widely used across automotive, marine, construction and industrial applications where durability, impact resistance and long-term reliability are essential.

This 300-gram chopped strand mat provides excellent strength and rigidity when used with polyester or epoxy resin. Once saturated, the fibres bond tightly together to form a tough, solid laminate that reinforces damaged or weak areas. It is ideal for rebuilding cracked panels, strengthening mouldings, and forming new fibreglass components.

Compared to lighter fibreglass tissues, this heavy-duty mat offers greater thickness and load-bearing capability, making it suitable for areas that experience vibration, pressure or mechanical stress. Despite its strength, the mat remains flexible enough to be moulded over curved and uneven surfaces, ensuring a close fit and strong adhesion.

Who should buy this?

This product is perfect for car body repairers, boat owners, fibreglass fabricators, builders and serious DIY users. It is ideal for repairing vehicle panels, bumpers, boats, caravans, storage tanks, roofs, pipes and composite structures where a strong internal reinforcement layer is required.

What problem does it solve?

Cracked, weak or damaged fibreglass structures can fail over time if not properly reinforced. This glass fibre mat provides a thick, strong repair layer that restores structural integrity and prevents further cracking or breakage.

Why is it better than cheap alternatives?

Low-quality fibreglass mats may have uneven fibre distribution, poor resin absorption and weak bonding. This 300g mat is densely packed, evenly layered and engineered for maximum resin uptake, delivering stronger, longer-lasting repairs with professional results.

UK Uses & Applications

Commonly used across the UK for automotive body repairs, marine maintenance, caravan and trailer restoration, fibreglass moulding, roofing, guttering and general composite fabrication, this mat provides dependable performance in both professional and DIY environments.

FAQs

Can it be layered for extra strength?
Yes, multiple layers can be applied to increase thickness and structural strength.

Is it compatible with epoxy resin?
Yes, it works with both polyester and epoxy resins.

Can it be cut easily?
Yes, it can be trimmed with scissors or a craft knife.

Is it suitable for structural repairs?
Yes, it is designed for heavy-duty fibreglass reinforcement
