Bondo Fiberglass Mat

Slightly thicker than the Bondo® Fibreglass Cloth, the Bondo® Fibreglass Mat is recommended when additional strength is required on more severe repairs like larger holes and cracks. To use, cut each piece of Bondo® Fibreglass Mat to size and build layers as needed. When used with Bondo® Fibreglass Resin, repairs are 100% waterproof, making the products ideal for tub, shower, sink, pool, hot tub, boat repair and more. This product can also be used on additional surfaces such as wood, concrete and metal to provide extremely strong, durable and waterproof repairs.
