| Hints & Tips for an Optimal Tape Application
|
| Surfaces |
| It is very important ot observe some specific rules when applying ahesive tapes. First, we recommend to make a pracitical test on the adhesive surface to ensure the compatibility of the surface and the adhesive tape. Due to the various surface materials used in practise, tests by the user are the most effective way of testing the material before use. Following are some hints and tips for saving costs and time concerning the most common surface materials when using the appropriate safal products. To avoid damage, interactions and costly extra work, we will explain some critical surfaces as shown in the following diagrams.

| Contamination and Temperature |
| In general, the adhesive surface should be dry, free dust, grease, oil, humidity and other contamination. Silicones and waxes, as well dirty surfaces decrease the level of adhesion. The ambient temperature should be from + 5 °C up to + 40 °C. Coldor to warm adhesive tapes should be allowed to adapt to the enviroment. Caution is advised in storage of adhesive tapes, e.g. at a building site, in vehicles, where the temperature may very. Possibly, damage to the adhesive tape could occur at these extremes and consequently lead to damages of the surface. The temperature where the adhesive tape is to be sed should be above + 5 °C. To ensure a residue free removal, the tape should be removed at an angle of 45°. |

| Wood |
| The pre-treatment of wood is important to avoid damage. Non sufficient ply bond strength of the wood can lead to wooden fiber splinters during removal of the tape. Incompletly dried paints which were applied on old and dirty surface have, during removal, a better bond to the tape than to the surface. Such damage can be identified due to occasional residues which don't cover the whole length/width of the tape. |
| |
| Metal |
| Copper, sinc and lead can be discoloured due to chemical reactions. An adhesive tape application should therefore be short term and preferably use narrow widths. |
| |
| Anodised Aluminium Surfaces |
On window and door profiles or roller shutters with poor anodised finishes, adhesive residues can occur during removal of the tape. We recommend to pre-treat the aluminium surface with an ink-soaked cloth.
If ink residues appear, it shows a badly compressed surface and therefore and adhesion test is recommended berore application. Only low tack tapes should be used. |
| |
| Natural and Artifical Stone |
| We do not recommend applying adhesive tapes on natural and artificial stone as discolouring can become visible on the surface, even on short term applications. |
