A simple, manual molding method in which the product is produced by the overlapping of successive layers of suitable carrier materials.
The gel coat is applied in the first place by hand or spraying (using a special machine – SPRAY / GUN version).
The carrier materials that give laminates relevant physico -mechanical properties (eg. tensile strength, elasticity, impact and compression strength, etc.) are most commonly fiberglass, technical fabrics, veils, coremats which are impregnated by hand with properly chosen resin.
