May also be used with epoxy to provide an abrasion-resistant covering for wooden structures. When wet out with epoxy, the 4 and 6 oz fabrics become transparent, allowing a clear, natural wood finish.

It is critical that the scarf angle is set at a minimum ratio of 12:1 and that the patch thickness matches the original laminate. Matching the original thickness ensures that the stiffness will be the same as the surrounding area, reducing the chance of a crack around the repair area.\u003c\/p\u003e\r\n\u003cp\u003eCreating a scarf angle on the original laminate helps in many ways. It provides a substantial amount of surface area for adhesion and acts as a transition zone so that the difference in properties of the new and original laminate are not concentrated at one point. We suggest a minimum 12:1 scarf ratio between the length of the scarf and the laminate thickness. This ratio applies to both skins when repairing a cored laminate.\u003c\/p\u003e\r\n\u003cp\u003e\u003cem\u003e—Excerpted from \u003c\/em\u003e\u003cem\u003eCommon Errors in Fiberglass Repair\u003c\/em\u003e\u003cem\u003e by Jeff Wright, Epoxyworks 38\u003c\/em\u003e\u003c\/p\u003e\r\n\u003cdiv class=\"content-box bg-transparent\"\u003e\r\n\u003ch3\u003eBeveling Fiberglass in a Transom Repair\u003c\/h3\u003e\r\n\u003cp\u003eThe fiberglass thickness determines the bevel length, which is also the distance from the corner to the location of the cuts for removing the fiberglass skin.

If the fiberglass is ¼” thick, the cut line will need to be at least 3″ in from the edge of the perimeter to allow for a 3″ bevel.
