3M Company 488 Fiberglass Repair Mat 8 Sq Ft

Product Description

The 3M COMPANY 488 is a non-woven fiberglass mat designed for repairing badly damaged surface areas. Constructed from 100% non-woven fiberglass, it provides a strong, conformable substrate that bonds well with compatible resins and coatings. The mat covers 8 square feet per unit, giving technicians enough material to address substantial damage in a single piece. It is used in repair applications across trades and industries where fiberglass reinforcement is required to restore structural integrity to deteriorated or compromised substrates.

The 3M COMPANY 488 is suited for repair scenarios involving badly damaged areas that require a reinforcing layer before finish coatings or topcoats are applied. It is appropriate for use in HVAC, plumbing, pool, and general maintenance contexts where fiberglass repair work is performed. The mat format allows it to be cut and shaped to fit irregular damage patterns, making it practical for field repair work.
