Laminating in a mould

When laminating in a mould, one needs to apply a gel coat first. As soon as the gel coat has dried (after 20 minutes), the object can be laminated immediately (within one hour for optimum adhesion) to ensure that an optimum adhesion between the gel coat and the laminate is achieved. Apply some A1 in the mould and spread it equally over the surface. Then apply an A1 triaxial fibre, which has been cut to size. Then apply A1 again and work it into the triaxial fibre. Another layer of triaxial fibre can then be applied, the process is repeated this way. Apply at least two layers of fibres, depending on the desired thickness and strength. Each layer of triaxial fibre results in a thickness of approximately 1 mm. Should the product require additional thickness, this can be achieved in the following ways:

- By applying a layer of sandwich material (followed by 1 or more layers of triaxial fibre).
- By applying a layer of A1 mixed with nylon fibres and/or Poraver (check for suitability for outdoor applications). Also followed by one or more layers of triaxial fibres. 

 


Laminating around an object 
Objects, for example made of modelling foam, can be coated with A1. First apply the A1 onto the foam, followed by triaxial fibre. Work the A1 in the triaxial fibre. Apply additional A1 in dry spots. Apply at least two layers of triaxial fibre in this way. Each layer of triaxial fibre has a thickness of approximately 1 mm. Apply a layer of A1 gel coat, based on Thix B or a mixture of A1 and ATP powder, to achieve a smooth finish. It is possible to add a sealer layer for the outdoor application. When the A1 is just about dry, the surface can be smoothened by using a wet sponge. After the object has fully cured, it can be sanded with wet waterproof sanding paper. If used for outdoor applications, the item is now ready for the application of a layer of sealant.
