Epoxy Surfboard

The epoxy surfboard is very fragile, and should be treated with great care. The barrels most often occur when loading the table without having a degree of caution when you end up on the rocks or, very often, with close encounters with other surfers. The parties are more likely to break the fins, the aft edges and prua. Prima to do the repairs necessary to determine whether you have a table-clark foam or polystyrene. In the case of bread-clark foam may be used indiscriminately polyester or epoxy surfboard resin, polystyrene in the case of bread you can 'use only epoxy. The polyester resin melt in this case the bread, if applied. Should be aware that the polyester resin and 'cheapest of the epoxy surfboard resin. Resin (epoxy or polyester) with a catalyst (the amount of catalyst for the polyester resin should be about 2 / 3%, while for the epoxy surfboard must be indicated on the package). Unidirectional glass fiber (used to attach the fins). You can also get unraveling of the mat until you get a bunch of fibers with a diameter of about 0. 5 cm for a length of 70-80 cm. Now for the repair. First, thoroughly clean the hole and the surrounding area with sandpaper from 200 to ensure better adhesion of the tissue that then will apply; make sure that the repair area is dry. If the hole is small, prepare the resin with the addition of beads (the mixture should be white and slightly viscous) and fill the hole. If the hole is large, the foam should be filled with perfectly shaped. Cut a piece of glass fabric a little larger than the hole (1 or 2 cm larger than the hole). Prepare a new mixture of resin and catalyst and try to do a little more quickly if you use the polyester resin. if the outside temperature is high and if you used the same container as before and there is still not completely dry resin, the resin before heating the mixture will dry before using. Apply over the hole in the glass cloth, resin-impregnated. Let dry and apply more of the liquid resin for polishing. Do not rub the fabric. If the damage can also be applied requires two pieces of fabric, a smaller one below and a larger one above. Once dry, sand with 100 paper, then with the paper 200 to finish and then polishing the surface with the paper 400. Glue the fin with quick-setting glue. Resin impregnated unidirectional fiber glass and put it around the base of the fins to round the corner. Cut two pieces of glass mat long as the fin width and about 3 cm to be applied to L in both sides. Prepare two large pieces of mat time around 6 / 7 cm to be applied also in the same place and in the same way as before. Let everything dry and proceed with sanding as before. . .
