It’s especially effective for repair work over aged fiberglass hulls and decks, where a plain biaxial cloth may not bond as reliably without a separate mat layer. For new builds, it simplifies multi-layer schedules by combining two fabric functions into one, reducing layup time and the risk of misalignment between separate layers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTip:\u003c\/strong\u003e The mat side should face the substrate. Wet out the mat layer first to ensure full saturation before the biaxial fibers are pressed into the laminate. Use a consolidating roller to remove air pockets and ensure intimate contact between the mat and the substrate surface.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51233004224548,"sku":"655-73820","price":1519.29,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/655-72710_5d19f6ee-c947-4316-99eb-58bdca89dbaf.jpg?v=1786152021","url":"https:\/\/marisolmarine.com\/products\/west-system-biaxial-e-glass-fabric-with-mat-22oz-50in-x-20yd","provider":"Marisol Marine Company","version":"1.0","type":"link"}
