Standard Surface Preparation for Tape Applications

Standard Surface Preparation for Tape Applications

For better tape results, it is important to prepare the surface to promote good bonding between the tape and the substrate. If the surface is not well prepared, the adhesive may not be as effective as it may come into contact with contaminants or other types of materials which may end up compromising its integrity.

Here are some of the standard surface preparation which ought to be considered if good bonding results are desired:

The Basic Preparation

In most of the cases, the surface preparation usually features a good scrub with a mixture of water and isopropyl alcohol. The water in the mixture will get rid of dust and dirt on the surface, while the alcohol will dissolve any light grease which may be present on the surface.

After the scrubbing, the surface should be allowed enough time to dry before the adhesive tape is applied. Additionally, once the surface is cleaned and before the tape is applied, it should not be touched, since fingers may have oils and other contaminants that may affect the bonding.

Heavy Oil Removal

The above preparation method may not be the best if there are heavy oils on the surface. In such a case, a suitable degreaser or a solvent based cleaner is recommended. Ideal solvents and cleaners may include citrus based cleaners, naphtha, and mineral spirits amongst others.

Surface abrasion

There are certain times when surfaces may require roughing up before the application of the adhesive tape. Processes such as sanding may be ideal to loosen up chipped paint, rust, or accumulated dirt that may end up compromising the bond between the surface and the adhesive. When the surface is sanded in a circular motion to create shallow scratches, a strong and persistent bond will be created between the adhesive and the surface.
