How to glue fiberglass

The expression "glue fiberglass" is often used to mean – to make a product out of fiberglass and polymeric resin (often epoxy). Fiberglass, combined with resin is a plastic material so that it is possible to make almost anything: a boat, funny mask, "skirts", medieval knight armor, etc. in the technology of the product becomes sturdy and durable.

You will need

• structural fiberglass;
• – epoxy resin with hardener;
• – polyurethane foam;
• – universal putty;
• – spatulas;
• – emery emery cloth;
• – paraffin or stearin;
• – brush with stiff bristles;
• – cutting tools (box cutter, jig saw, razor blades, etc.).

Instruction

1. Manufacture any product made of fiberglass is carried out in two stages: the first form is (a matrix) for it, then the product itself.Manufacturer matricielle frame (blank) for the matrix. Its shape and dimensions must correspond to the product for which it is intended. Depending on the type of product can be used in various material: wood, wire, plastic. If you intend to produce the product of complex shape, as the surface layer of the matrix it is convenient to use the foam. In this case, determining the size of the frame, assume that on top of it will be the layer of foam with a thickness of 3-4 cm.
2. Apply on the blank foam layer having a thickness of 3-4 cm Foam is preferably applied not one but several layers. After the final hardening of the matrix give the shape of the product. For surface treatment of foam, use a utility knife, razor blades, sandpaper, jig saw, grinder.
3. Apply to the surface of a matrix composition suitable for hiding pores and smoothing the surface, for example, construction of a universal putty. After drying prostituate it with emery cloth. Repeat this operation as many times as necessary in order for the matrix surface was smooth.
4. Cover the matrix one of the separation material serving to prevent sticking of the product to the form. This may be a paraffin wax, stearin, parquet Polish, etc. After application and drying of the composition Polish the surface with a piece of cloth.
5. Manufacturer italianmusic epoxy resin with hardener in required proportion and apply it with a spatula a thin layer to the matrix. Give time for the resin to harden, then apply a second coat.
6. Apply resin to the fiberglass, roll her stitcher roller or press and seal brush with coarse bristles. Make sure the fiberglass is completely saturated, and is a very important requirement was removed all the air from the cloth. Otherwise, it may result in local delamination and blisters. If on an uneven surface was formed pleat fiberglass, cut it with a knife or scissors and press down firmly on the edges to the surface.
7. Repeat greasing resin and decals fiberglass a few times – depending on what strength you want from the product. Usually limited to three to five layers of fiberglass. After the final polymerization of the resin, remove the product from the mold. Now it is possible to paint and varnish.
