West epoxy and the pumps… worth every penny. What type of resin? The underlying resin WILL cure and the patch will be hard, except on the surface. An alternative is to spray the area with PVA mold release. You may also be able to find the additive separately. Bnystrom, I have not had that experience because the West epoxy patches I have done WILL get hard and non-tack on the surface without use of a film covering.

Oh, there may be a slight gummy feeling from the amine blush, but the surface of the patch is hard. With epoxy, sure. For small applications use 10 drops of hardener per ounce 2 tablespoons of the resin. For larger applications, use half of the liquid hardener supplied, to half of the resin container. The hardening process begins immediately, so only add catalyst to a working quantity. The curing process generates heat within the resin.

Adding too much color will slow down or inhibit the cure. During the curing process, the catalyzed resin goes through a series of stages from a liquid to a 'soft gel' in about 15 to 20 minutes , a 'firm gel' in 30 minutes and finally to a 'click-hard' cured stage in 1 to 24 hours. Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly. About the Author: Set the fiberglass in the sun.

The curing of fiberglass resin is an exothermic reaction, meaning that heat makes it work. Use a heat gun on the fiberglass. If the heat of the sun isn't enough, a more intense heat source may be needed. Spray a mist of catalyst onto the fiberglass with a spray bottle. Epoxy resin adhesives will bond all woods, aluminum and glass well. It does not bond to Teflon, polyethylene, polypropylene, nylon, or Mylar.

It bonds poorly to polyvinyl chloride, acrylic and polycarbonate plastics. The only way to tell if an epoxy will bond to a material is to try it. Resin poured in a thin layer It can be normal for some resins , when poured in a thin layer, to be bendy. Some resins , especially doming resins , can be flexible after the full cure time.

If you want to give the resin extra time to cure, make sure it stays warm and give it another two to seven days to fully cure. Epoxy that remains sticky after the curing time will stay sticky unless the following measures are taken to repair the situation.

If you do not scrape off the wet epoxy , this could result in leaking under the new Epoxy coat. If on trailer wrap tarp lossely around boat, then a second tarp around that one. It will cut down on wind chill, but remember water in engine etc. How long does fiberglass patch take to dry? Fiberglass resin patch kits vary in drying time.

Some cure in about three hours, while others require up to 12 hours. Read the label to ensure you wait long enough for the repair to fully harden. What temperature does it need to be for epoxy to cure? One of the most important factors to ensure your epoxy resin cures properly is temperature: the ideal temperature for both your ArtResin and your workspace is slightly warmer than room temperature: F or C.

Sometimes resin that cures soft and bendy cured at too cold a temperature. Too much water can increase the drying time. Fiberglass becomes waterproof once resin is applied and has cured. Prior to applying the resin the fibreglass fabric is not waterproof on its own, while the glass fibers themselves are impermeable to water, the fabric has small gaps between them which water can permeate through.
