We’ve used gel coat over epoxy for decades. It’s in our fiberglass boat repair videos and discussed it our magazine, Epoxyworks.\u003c\/p\u003e\n\u003cp\u003eThere are three key factors for success with gel coat over epoxy:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eMix your epoxy resin and hardener at the proper ratio (Mini Pumps make this a snap).\u003c\/li\u003e\n\u003cli\u003eAllow the epoxy to fully cured.\u003c\/li\u003e\n\u003cli\u003eBefore applying gel coat, remove any amine blush from the cured epoxy surface. Amine blush is simply an easily removed wax-like film that can form as a byproduct of the curing process. WEST SYSTEM 105 Resin\/207 Special Clear Hardener does not blush.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eGel coat manufacturers shy away from approving the use of non-air inhibited gel coat over epoxy because they’re concerned amine blush will interfere with the gel coat’s cure. All you need to do to remove the blush is wash the surface with plain water. It’s then ready for you to prep for paint or gel coat.\u003c\/p\u003e\n\u003cp\u003eThis process is even easier if you use Release fabric. This fabric is applied to uncured epoxy, protecting the surface from contamination. As the epoxy cures, any blush will form on the\u003cem\u003e outside\u003c\/em\u003e of the release fabric. Simply remove the release fabric after cure, and it will take the blush with it. The resulting surface is ready for you to prepare it for paint or gel coat.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEpoxy’s penetration into wood\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEpoxy does more than sit on the surface of the wood. Some epoxy will remain on wood surfaces, and some of it will penetrate into the wood. The amount of penetration depends mostly on how the wood fibers are oriented. Face grain will not absorb nearly as much epoxy as end grain. But since WEST SYSTEM Epoxy is very strong and an excellent adhesive, it strengthens the wood and makes it waterproof.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e105 Epoxy Resin batch size and cure speed\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYou need to know that in larger quantities, epoxy cures much faster. This is because epoxy generates heat as it cures and also cures faster at higher temperatures. This snowball effect increases until the epoxy cures—which in very large batches could take only a couple of minutes. Large pots of mixed epoxy can generate enough heat to cause a runaway exothermic reaction. This can include, smoking, melting the mixing cup or even starting a fire. Spreading epoxy thin allows the heat to dissipate and slows its cure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEpoxy casting \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWEST SYSTEM Epoxy has a very low percentage of shrinkage. In fact, the standards used to calculate shrinkage of other resins (polyester and vinyl ester) aren’t used with WEST SYSTEM because it shrinks so little to measure that way.\u003c\/p\u003e\n\u003cp\u003eWhen epoxy is used to fill holes drilled into wood, it will soak into the end grain. This might look like shrinkage, but it’s not.\u003c\/p\u003e\n\u003cp\u003eBack in the late ’70s and early ’80s, Gougeon Brothers Inc. manufactured over 4,000 wind turbine blades and their molds using WEST SYSTEM Epoxy. It was commonplace to see a 70-foot long mold shrink \u003cem\u003e3\/32″ over the entire 70-foot length\u003c\/em\u003e. That represents shrinkage of just .01% on a laminate consisting of fiberglass and WEST SYSTEM Epoxy.\u003c\/p\u003e\n\u003cp\u003eAvoiding exotherm when casting\u003c\/p\u003e\n\u003cp\u003eWhen casting epoxy, heat buildup can become an issue. Excessive heat can make WEST SYSTEM Epoxy can shrink some. Pouring epoxy in great depths creates the potential for the epoxy to get very hot due to the exothermic reaction resin and hardener have. While exotherm is a normal part of the curing process, you must always keep it under control. Do this by using smaller pours when casting, and working in a cool environment.\u003c\/p\u003e\n\u003cp\u003eAny shrinkage that does occur generally happens while the epoxy is still liquid, but when an intense amount of heat is present, epoxy doesn’t stay liquid for very long. As the heat dissipates, the difference in temperature between the top and bottom of the casting can shock the now solid epoxy and it may crack. To avoid this, make deep castings in layers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdding extra hardener (don’t)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile adding extra catalyst to polyester resins can lead to a faster cure, you should \u003cstrong\u003enever add extra hardener to epoxy resin\u003c\/strong\u003e. Epoxy reaches cure when the resin molecules cross-link with hardener molecules. When there is too much of either resin or hardener, unlinked molecules are left over. This can result in uncured epoxy or compromised cure strength. Always mix epoxy resin and hardener as close as you can to the recommended ratio.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClamping force\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike traditional wood glues, WEST SYSTEM Epoxy is stronger than wood. Because of this, it is beneficial to have some epoxy between the objects you are gluing together whether they are wood, fiberglass, or other materials. As long as the epoxy is contacting the entire surface of both substrates, no clamping pressure is needed.\u003c\/p\u003e\n\u003cp\u003eThe goal clamping is to simply ensure the epoxy \u003cem\u003econtacts the entire surface for the duration of the cure time\u003c\/em\u003e. Moderating clamp force is all you need. If you aren’t using a filler, and apply too much clamping force, this can result in a glue-starved joint. This makes future joint failure much more likely. Glue starved joints are weaker than their counterparts. Avoid glue-starved joints by following the one- or two-step bonding method.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFiller and Epoxy Strength\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile certain fillers will increase the density of epoxy, this does not correlate to higher physical properties or increased adhesion strength.

Cellulose is the structure of the wood. Replacing it is not as simple as brushing on a coat of solvent-thinned epoxy. Solvented epoxy may replace some of the strength, but isn’t a permanent repair—it won’t restore the strength of the wood fibers. To make a permanent repair, replace the entire rotten area with fresh wood and sealed with epoxy. Addressing rot this way will make the repair area stronger than it was before the rot occurred.\u003c\/p\u003e\n\u003cp\u003eWhy remove rot?\u003c\/p\u003e\n\u003cp\u003eRot needs four major components in order to continue growing:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eFood\u003c\/li\u003e\n\u003cli\u003eMoisture\u003c\/li\u003e\n\u003cli\u003eOxygen\u003c\/li\u003e\n\u003cli\u003eWarmth\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eCutting off just one of these components is enough to cause the rot to go dormant. Solvented epoxies are supposed to cut off rot’s food source by encapsulating and contaminating the wood that the rot spores consume. However, the remaining three components: moisture, oxygen, and warmth, can still penetrate wood coated with solvented epoxy.\u003c\/p\u003e\n\u003cp\u003eThis is because solvented epoxy is a poor moisture barrier. Rot spores will remain in the wood, and even when encapsulated in solvented epoxy, they will only go dormant. Un-isolated rot pores will continue devouring the cellulose, causing more rot.\u003c\/p\u003e\n\u003cp\u003eThis is why we recommend removing the rotten wood and replacing it with fresh wood that is sealed with several coats of WEST SYSTEM Epoxy.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.westsystem.com\/wp-content\/uploads\/105-SDS.pdf\" rel=\"noopener\" target=\"_blank\"\u003eSDS\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan id=\"page66R_mcid50\" class=\"markedContent\"\u003e\u003cspan dir=\"ltr\" style=\"left: 299.989px; top: 1104.96px; font-size: 16.6px; font-family: serif; transform: scaleX(1.05122);\" role=\"presentation\"\u003eOver time, 105 Resin will thicken slightly and will therefore require extra care when\u003c\/span\u003e\u003cbr role=\"presentation\"\u003e\u003cspan dir=\"ltr\" style=\"left: 299.989px; top: 1124.96px; font-size: 16.6px; font-family: serif; transform: scaleX(1.03891);\" role=\"presentation\"\u003emixing.

With epoxy, the goal clamping is to simply ensure the epoxy contacts the entire surface for the duration of the cure time. Moderating clamp force is all that is required.\u003c\/p\u003e\n\u003cp\u003eIf an epoxy filler is not used and a high clamping force is used, the result can be a glue-starved joint which will make bond failure much more likely. Glue starved joints are weaker than their counterparts. Avoid glue-starved joints by following the one- or two-step bonding method.\u003c\/p\u003e\n\u003cp\u003eRead more about glue-starved joints and other epoxy considerations at Epoxyworks.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.westsystem.com\/wp-content\/uploads\/206-SDS.pdf\" rel=\"noopener\" target=\"_blank\"\u003eSDS\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"West System","offers":[{"title":"206A 7oz","offer_id":48014369521979,"sku":"206-A","price":39.99,"currency_code":"USD","in_stock":true},{"title":"206B 27.5oz","offer_id":48014369554747,"sku":"206-B","price":89.99,"currency_code":"USD","in_stock":true},{"title":"206C 121oz","offer_id":48014369587515,"sku":"206-C","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/7539\/6411\/files\/206combo.jpg?v=1713649921"},{"product_id":"207-special-clear-hardener","title":"207 Special Clear Hardener","description":"\u003cp\u003eBlush-free 207 Special Clear Hardener was developed for coating and fiberglass cloth application where an exceptionally clear, moisture-resistant, natural wood finish is desired.

To prevent this, first coat them with a craft decoupage glue like Mod Podge™.\u003c\/li\u003e\n\u003cli\u003ePorous materials such as burlap can trap a lot of air bubbles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBefore you get started, dam the perimeter of the surface you plan to coat. Duct tape around the bottom edge of the surface to prevent the epoxy from dripping. For coatings ¼” thick, tack a piece of stock molding with 6 mil plastic under it around the table’s perimeter. Make sure the surface is level and the temperature of the substrate is stable before pouring epoxy.\u003c\/p\u003e\n\u003cp\u003eTo prevent bubbles “outgassing” from the surface this, brush one or two thin coats of epoxy onto the surfaces. Allow this to reach gelation (about 6 hours at room temperature) before pouring epoxy. If you wait more than 18 hours before pouring your deeper layer of epoxy, be sure to sand the seal coating before pouring the epoxy mixture.\u003c\/p\u003e\n\u003cp\u003ePierce a hole in the bottom of a mixing pot. Cover this hole with duct tape.

Allow this mixture to stand for about one minute to allow the bubbles time to reach the surface so the epoxy is deaerated.  Peel back the duct tape covering the hole and allow this deaerated epoxy to flow onto the table surface. Pour close to the surface so the epoxy won’t splash and introduce air into the mixture.  Stop the hole with tape when the container is nearly empty so bubbly epoxy isn’t poured onto the surface.\u003c\/p\u003e\n\u003cp\u003eLimit the depth of the pour to ¼”. If a thicker layer is desired, allow the lower layer to set up before adding a new layer. Casting epoxy too thickly in a single pour, or casting more epoxy over a layer that has not set up can cause uncontrolled exotherm. This will ruin your project and could possibly destroy pieces of memorabilia you’ve placed in the casting.\u003c\/p\u003e\n\u003cp\u003eConsider the temperature of your work area when deciding how deep to pour.

Without exception, adding pigment to WEST SYSTEM Epoxy will weaken the cured mixture to some degree. Because of this, we suggest you use very small amounts of pigment, about 5% by weight. As a result, thin films of colored epoxy are somewhat transparent. It usually requires several coats to make the film opaque.\u003c\/p\u003e\r\n\u003cp\u003eWEST SYSTEM pigments are available in three colors, white, black and gray. We suspend the pigments in an epoxy resin base which allows them to blend thoroughly into the epoxy to make very uniform colors. Because the pigment has an epoxy resin base, it is important not to add more than the recommended amount. Adding an excessive amount of pigment to the epoxy could alter the resin\/hardener ratio, compromising cured epoxy performance.\u003c\/p\u003e\r\n\u003cp\u003eIf you need to make a tinted epoxy putty for filling defects, mix WEST SYSTEM epoxy with 406 Colloidal Silica Filler to make the putty. The addition of 406 to the epoxy results in an easily colored, smooth, off-white paste that can be tinted with one of the pigments.\u003c\/p\u003e\r\n\u003cp\u003eEpoxy, tinted or clear, does not have good UV light resistance. An epoxy coating exposed to UV will yellow, become opaque, and eventually flake off.

The molded chambers and passageways accurately control the ratio and prevent the resin and hardener from contacting each other until they are outside the cartridge.  \u003c\/p\u003e\r\n\u003cp\u003eExperienced WEST SYSTEM users are familiar with the handling characteristics of 105 Epoxy Resin®-based epoxy thickened with 406 Colloidal Silica Filler that allows it to be non-sagging, yet trowel easily. Six10 Adhesive provides the same handling properties right out of the cartridge but achieves it with shear thinning, a property that allows the viscosity of the adhesive to become lower when a shear force is applied. A shear force is applied when the epoxy is mixed or spread out over a surface, which causes the viscosity of the Six10 to become lower resulting in a “thinner” consistency. When you are done applying or mixing Six10 and it is no longer being worked, or “sheared,” it will start to increase in viscosity and develop a thicker consistency. This shear-thinning property enables Six10 to be easily dispensed out of the coaxial cartridge and through the static mixer and then tooled smoothly into a fillet that won’t sag during the cure cycle. The shear-thinning property also enables Six10 to be used for wetting out light to moderate weight reinforcing fabrics such as fiberglass and carbon fiber. This feature makes the product convenient for performing small fiberglass boat repairs. If you use a stiff plastic spreader, Six10 can wet out any fiberglass fabric lighter than 12 oz per square yard as a result of its shear thinning characteristics.\u003c\/p\u003e\r\n\u003cp\u003eSix10 is a two-part thickened epoxy adhesive in a convenient, self-metering cartridge. For permanent, waterproof, structural gap filling and gluing. Bonds to wood, fiberglass, metals, and masonry. With the 600 Static Mixer (included) you can dispense fully mixed adhesive right where you need it using a standard caulking gun. Trim the mixer tip to suit your job. A 1\/4\" diameter tip opening will dispense a bead of adhesive about 15 linear feet. A 1\/8″ diameter tip opening will give you a bead of adhesive about 75 linear feet. Working time is 42 minutes at 72ºF.

Remove the plug before use and replace it afterward. As resin is emitted from one side and hardener from the other, the plug will get a residue of resin and hardener on it. For best results, clean the tip before replacing the plug. Try using a stir stick, paper board or poster board with a slot cut into it. Use this to swipe over the divider.\u003c\/li\u003e\r\n\u003cli\u003eWhen you replace the plug be sure it is oriented the way it was when it was first removed, otherwise resin and hardener on the plug will contaminate the opposite side of the port and cure. To prevent this, before you use the product remove the retaining nut and put one magic marker dot on one side of the removable plug and a corresponding dot on the same side of the cartridge. When replacing the plug, you’ll always be able to orient it properly.\u003c\/li\u003e\r\n\u003cli\u003eReplace the plug, align the dots as described earlier, then replace the threaded cap. The tube will be ready for use next time you need it. Always replace the retaining nut, as hydraulic pressure may force the plug out.\u003c\/li\u003e\r\n\u003cli\u003eStore cartridges of Six10 Thickened Epoxy Adhesive away from sunlight in a cool, dry place.

Often, you’ll apply some epoxy to your work surface and proceed with assembly. While you’re working, the adhesive in the mixer will eventually begin to cure.
