Fibre Glast Breather-Bleeder Cloth 5 yd - Vacuum Bagging Breather

In this review of the Fibre Glast Breather-Bleeder Cloth the bottom line is simple: this is a practical, no-nonsense breather layer for people who vacuum bag wet layups of fiberglass, carbon or Kevlar and want cleaner, more uniform cures. The reviewer finds it most useful for DIY builders and small shops that already use vacuum bagging or degassing chambers; the cloth's primary advantage is consistent vacuum pressure and resin absorption, which helps produce lighter, stronger parts without changing core materials or processes.

Key Features

• Breather-Bleeder action: The cloth evens vacuum pressure under bagging film and provides a path for air and volatiles to escape, reducing pinholes and trapped air in laminates.
• Resin absorption: As a bleeder layer it soaks up excess epoxy and resin, which helps prevent resin pooling and produces a more uniform laminate finish.
• Generous size: The 60in x 180in dimension covers larger parts or multiple smaller pieces in a single layup, reducing the need for seams or overlapping sheets.
• Lightweight fabric: At about 4 oz this cloth drains and breathes without adding significant bulk or weight to the vacuum stack.
• Instructional support: The product includes professional-level instructions and guided videos, which help users unfamiliar with vac bagging get reliable results.
• First quality certified: The fabric is sold as first quality, intended for repeatable results across batches in demanding marine and industrial applications.

Who It's For

This breather-bleeder cloth is aimed at hobbyists, boat repairers, and small composite shops that already perform wet layups and want to step up to vacuum bagging or use a degassing chamber. It is useful for working with fiberglass, carbon fiber, and Kevlar where extracting excess resin and trapped air improves strength-to-weight and surface quality.

Those who should look elsewhere include people who never vacuum bag or who require integrated peel ply or specialized engineered consumables for automated production; this is a simple breather fabric, not a multi-layer kit that replaces peel ply or release films for every workflow.

Pros & Cons

Pros

• Performs well as a breather layer to promote even vacuum and reduce trapped air.
• Absorbs excess resin to help produce lighter, more consistent laminates.
• Large 60in x 180in roll covers big parts or multiple small pieces in one run.
• Includes professional instructions and video guidance for DIY upgrades.

Cons

• Some customers report mixed perceptions of cloth quality, so careful inspection before use is advised.
• Not a substitute for peel ply or release film where those specific functions are required.

Frequently Asked Questions

Can this cloth be used with carbon fiber layups?
Yes, it is intended for use under bagging film with fiberglass, carbon, and Kevlar wet layups to remove air and excess resin.

Will this replace peel ply?
No, this product is a breather-bleeder layer and absorbs resin; peel ply and release films serve different roles and may still be needed in many workflows.

How much area does one roll cover?
One roll measures 60 in by 180 in, which equals 5 yd and can cover large parts or several smaller pieces in a single bagging session.
