How to Use Fiberglass Resin Patch Kits

Fiberglass resin patch is made of a hot curing resin or epoxy resin consisting of two parts: resin and hardening agent.You mix these parts together, produce a chemical reaction, generate heat inside, so that the material will harden due to damage such as glass fiber, steel and other holes and cracks on non-porous surfacesThese kits contain almost everything you need to fix these surfaces yourself.Clean the damaged area with a solvent (such as ethyl acetate or methyl acetate) to remove residues such as oil, grease or dirt.Solvents such as acetone are highly flammable and may be toxic.When using these how products, please read the product label and follow the instructions and safety precautions.Rinse the area with clear water to make it completely dry.Polish the area with coarse sandSand and sandpaper should be at least 1 inch after damageIf there is a crack, drill a small hole at the end of each crack.This prevents cracks from expanding under the patch.Smooth the sanding area by sanding with fine sandCoarse sand sandpaper, protruding at the edge, so that the damaged area remains horizontal with the undamaged surface around it.Wipe the sand area with a cloth stained with alcohol.Cut the glass fiber cloth included in the repair kit so that it can cover the area with sand.Place the cloth on the area and secure the edge tape in place with masking tape.Mix the resin and the hardening agent equally on one piece of cardboard or another disposable surface.Mix the two parts until you get a uniform color, but use only enough to complete the repair.Use the plastic hanger attached to the kit to apply the mixture to the glass cloth.Spread it out so that it is evenly distributed across the fabric.Remove the masking tape and spread the mixture to the exposed edge.Cover the repair with waxed paper or cellophane and leave a patch for overnight treatment.The drying time is different, and the fiberglass resin bag is also different.Some heal in three hours, while others take 12 hours.Please read the tab and make sure you wait long enough for the repair to fully harden.If you can make an impression in the patch with your thumbnail, it\'s not completely cured.Trim the edges with fine feathers and smooth the patchSand and sandpaper like 220-grit.Use more fine sandpaper, like 320-to 600-Grit until the patch is flat with the undamaged surface around it.Wait at least 12 hours after applying the patch to prime and painting the
