There are 4 types of adhesive for stickers and labels:-
- Static Cling
- High Tack (or Extra Permanent)
Static cling is basically no adhesive and uses the laws of physics to remain stuck by clinging to the surface.
Removable adhesive allows you to apply and remove without leaving any sticky residue.
Permanent is by far the most popular and will remain stuck under most conditions.
High Tack is used if the sticker needs extra grab due to the surface it’s being adhered to or it’s to be kept in extreme conditions.
Which Adhesive Should you Choose?
Unsurprisingly, it depends on what material the sticker will be stuck to and what environment it will be kept in.
If you need to reposition or easily remove the sign or sticker, a removable adhesive or no adhesive (static cling) are best. If the medium is relatively large, flat, hard and polished and also unlikely to move much or be subject to mechanical changes, windows, doors and metal surfaces, for example, then static cling is the perfect choice you can also reuse them over and over. Retail products or similar smaller items would require a standard removable adhesive.
For all other applications, a permanent adhesive is preferred. For all paper stickers and most vinyl ones, the standard adhesive is ideal but for extreme environments or low energy surfaces, a stronger option is available. Hi-tack or extra-permanent glue will cope with all conditions.
Whatever adhesive you choose, the application process is the same.
Step one - Always stick to a clean surface. You could use a solvent on a lint-free cloth. Water is adequate for dust but to remove grease or oil, an organic solvent like acetone or ethanol is best (check compatibility between solvent and surface first)
Step two - Remove the sticker from its backing. For best results, peel the backing from the label rather than the other way round to avoid deforming the label. Also, avoid touching the adhesive as oils and moisture from your fingers could interfere with the adhesive process.
Step three - Smooth the sticker or label from one edge across it to the opposite edge, smoothing out bubbles as you go. Pressing with a cloth or hard surface like a roller will further increase adhesion.
Step four - Once the adhesive is in contact with the intended surface it can take up to 72 hours for it to fully bonded.
The exception is our window sticker range which doesn’t have a chemical adhesive. Instead, it uses static cling to affix to flat, smooth glass surfaces.
Step one - Clean the glass surface and spray with a light mist of water.
Step two - Remove the paper backing.
Step three - Smooth the sticker from one edge with a cloth or squeegee eliminating any bubbles and moisture as you go.
