Cut to a convenient 30\" × 30\" sheet, it's well-suited for localized structural repairs, high-load laminate patches, and reinforcing areas subject to abrasion or impact — such as keels, skegs, transoms, and hull bottom sections.\u003c\/p\u003e\u003cp\u003eAt twice the weight of standard 6 oz. cloth, the 12 oz. weave builds thickness and stiffness quickly, reducing the number of layers needed to achieve structural laminate targets. It wets out with epoxy, polyester, or vinylester resin systems and can be painted or varnished once fully cured.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e12 oz. heavy-weight woven fiberglass — maximum strength per layer\u003c\/li\u003e\n\u003cli\u003e30\" × 30\" pre-cut sheet — ideal for patch repairs and localized reinforcement\u003c\/li\u003e\n\u003cli\u003eBuilds thickness and stiffness faster than lighter fabrics\u003c\/li\u003e\n\u003cli\u003eCompatible with epoxy, polyester, and vinylester resin systems\u003c\/li\u003e\n\u003cli\u003eSuitable for use over wood or existing fiberglass substrates\u003c\/li\u003e\n\u003cli\u003ePaintable and varnishable once cured\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStructural hull repairs — keel, skeg, transom, and bottom sections\u003c\/li\u003e\n\u003cli\u003eHigh-load laminate patches on decks and bulkheads\u003c\/li\u003e\n\u003cli\u003eAbrasion-resistant overlays on wear surfaces\u003c\/li\u003e\n\u003cli\u003eReinforcing through-hull areas and fitting pads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eRelated Fiberglass Fabrics\u003c\/h3\u003e\u003cp\u003eFor lighter sheathing and laminating work, see the \u003ca href=\"\/products\/west-system-655-74010-4-oz-woven-glass-fabric-50-wide-10-yard-roll\"\u003e4 oz.

The 30\" × 30\" format is a practical size for most single-location repairs without the waste of buying a full roll. Steer customers toward lighter fabrics (4 oz. or 6 oz.) if they’re sheathing wood or doing cosmetic repairs where a smooth, transparent finish matters — the 12 oz. weave is harder to wet out smoothly and won’t go transparent. Recommend a slow hardener for large patches to allow adequate wet-out time before the resin begins to gel.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51233005404196,"sku":"655-74530","price":37.49,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/655-74010_7455d8c4-94c6-4759-b8c5-b677c716c180.jpg?v=1786152036","url":"https:\/\/marisolmarine.com\/products\/12-oz-woven-glass-fabric-30-x-30-sheet","provider":"Marisol Marine Company","version":"1.0","type":"link"}
