Metal, Coatings, Wall Coverings, Paper, and Textiles

What to keep in mind when applying adhesive tape to coatings, wall coverings, paper, and textiles.

Coatings

If you plan to mask coated surfaces, only tapes with low to moderate adhesion should be used. The length of time that the masking tape is left in place should be limited, because subsequent damage is possible (such as removal of coatings, discoloration, adhesive tape residue, etc.). 

The level of hold between the coating and the substrate must be greater than the hold between the adhesive tape and the coating. If in doubt, you should do a tape removal test or test adhesion.

Metals

For untreated metals such as zinc, titanium zinc alloys, and copper, protective measures such as films can lead to the buildup of condensation and thus to corrosion. This can be prevented by using masking materials open to diffusion, such as non-woven fabric without film. Alternatively, the adhesive can be applied for a short time or over the full surface.

All metal surfaces are subject to a natural oxidation and aging process. When adhesive tape is applied to metal, the oxidation and aging of these specific areas is reduced. This may cause these areas to have a different appearance from the rest of the surface once the adhesive tape is removed. This cannot be prevented. However, depending on the type of metal, the area will take on a uniform appearance within a short period (over several months).

In the case of treated metals, damage (such as discoloration and peeling) of the coating may occur.

The adhesion conditions, especially regarding temperature, must be taken into account.

Masking on Paper or Textiles

In the case of wall coverings such as wallpaper and textiles, adhesive tape with as low adhesion as possible should be used to avoid damage. We recommend the tesa® 4333 PV1 Precision Mask Sensitive.
