General Application Principles

To achieve the best adhesion of the stones and to avoid undesirable effects, carefully observe the following rules:

• All textile products selected for application of Preciosa stones must be clean, pre-washed, free of solid contaminant particles, without chemical finish (e.g. shrink-resistant, water-repellent etc.).
• While applying stones of various sizes, proceed from the smallest stones to the largest ones.
• While applying the stones, avoid moving them across the fabric.
• While applying the stones to fabrics of the mixture type, adapt the application values to those specified for materials with a lower heat resistance.
• While applying the stones to striking or rustic materials (tulle, terry, pile knitted fabric, mesh etc.), it is necessary to select a surface with sufficient contact area.
• While applying the stones to elastic materials (knitted fabrics, fabrics containing polyurethane fibres, e.g. Lycra, nylon stockings etc.), it is advisable to pre-stretch them slightly on a small thin board.
• While applying the stones to textile products (T-shirts, jerseys), it is necessary to insert a protective impermeable Teflon foil between the front and back of the garment.
• Various application techniques together with a variety of heat-setting devices may significantly affect the results. It is, therefore, advisable to test the individual application values first and adapt them to the particular conditions.
• Please, bear in mind that the adhesive does not set until after 24 hours, thus acquiring the ideal strength. All application procedures must, therefore, be completed by that time.
• In materials of lesser absorbency (fabrics made of viscose, silk or some other synthetic fibres), lower adhesion values can occur quite exceptionally.
