Surfaces to be bonded must be clean, dry, and free of dust, grease, oil, and release agents. For cleaning, only use clean cloths and material-compatible cleaning agents like tesa® 60040 Industry Cleaner. The components must be adapted to the ambient climate for a sufficient period to prevent the formation of condensation on the surfaces.

By cleaning the surfaces with a cleaning agent, you make sure all impurities are removed, such as:

• Dust
• Release agents
• Greases
• Waxes
• Plasticizers
• Oxidation layers, e.g. rust

Adhesive mass residues may remain if it occurs that an unsuitable adhesive tape is used or one has waited too long to remove the tape. In this case, tesa® 60042 Adhesive Remover can play a key role in the removal of such residues:

1. Dab residues with the adhesive side of a more adhesive product, such as tesa® 4651. 
2. Use tesa® 60042 Adhesive Remover. Removes most adhesive residues on glass, metal, and plastic surfaces reliably.
3. Alternatively use mineral spirits, isopropanol, or similar: Thoroughly soak and expel the adhesive mass with a plastic spatula to avoid damage. Please test the solvent on a concealed area first.

For bonding – especially outdoors and on surfaces that are difficult to bond – we recommend the use of a bonding agent, like our tesa® Adhesion Promoters. Bonding agents form a layer on the surface to which the pressure-sensitive adhesive adheres particularly well.

Indeed, there are plastics and other materials to which adhesive does not stick well. Polyethylene (PE), polypropylene (PP), Teflon, rubber, and silicone are some of these. Experts speak of "very low surface energy."

The exciting thing about a primer is it increases this surface tension, which lets the tape stick to the substrate more strongly. This layer also prevents water from entering the adhesive joint and thus enables consistent outdoor bonding.
