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.

The Basic Preparation

For most applications, a standard cleaning method involves using a 50:50 mixture of isopropyl alcohol (IPA) and water. The IPA effectively dissolves light oils and grease, while the water removes dust, dirt, and other particulates. This combination ensures that the surface is clean and free from contaminants that could interfere with the adhesive bond. After cleaning, it’s crucial to allow the surface to dry completely before applying the tape. Additionally, avoid touching the cleaned surface, as oils from fingers can compromise the adhesive’s effectiveness.

Heavy Oil Removal

In situations where the surface is contaminated with heavy oils or greases, the standard IPA/water mixture may not suffice. In such cases, it’s advisable to use a degreaser or solvent-based cleaner. Products like citrus-based cleaners, naphtha, or mineral spirits can effectively break down and remove these stubborn contaminants. After using these stronger cleaners, it’s essential to follow up with the IPA/water mixture to ensure all residues are removed, leaving the surface pristine for optimal tape adhesion. 

Surface Abrasion

Certain surfaces, especially metals or painted materials, may require mechanical abrasion to enhance tape adhesion. Methods such as sanding, wire brushing, or using abrasive pads can remove surface oxides, rust, or old paint layers. This process not only cleans the surface but also increases its roughness, providing a larger area for the adhesive to bond to. It’s important to use fine abrasives to avoid creating deep scratches that could weaken the material. After abrasion, the surface should be cleaned again with the IPA/water mixture to remove any debris or particles resulting from the abrasion process. 

Sealing Porous Surfaces

Porous materials like wood, concrete, or particleboard can absorb adhesives, leading to weak bonds. To address this, it’s recommended to seal these surfaces before applying tape. Sealing agents such as varnish, epoxy, or specialized primers can create a non-porous layer, ensuring that the adhesive remains on the surface and forms a strong bond. This step is particularly crucial for applications where the bond’s strength is critical.

Priming Low Surface Energy Materials

Materials with low surface energy, like certain plastics or painted surfaces, can be challenging for adhesives to bond effectively. In such cases, applying a primer can significantly enhance adhesion. Primers increase the surface energy of the material, allowing the adhesive to wet out more effectively and form a stronger bond. It’s essential to choose a primer compatible with both the substrate and the adhesive to achieve the best results.

Environmental Considerations

Environmental factors can also influence the effectiveness of tape adhesion. Surfaces should be free from moisture, as water can interfere with the adhesive’s ability to bond. Additionally, applying tape in extreme temperatures can affect its performance. It’s advisable to apply tape within the manufacturer’s recommended temperature range to ensure optimal adhesion.
