Frequently asked questions

We recommend that strips of tape be applied to the back of the poster and the Prestik be attached to this area as opposed to directly onto the poster.

Use lighter fluid or Low Aromatic Cleaning Benzine (LACB) to remove off fabric. Check for colourfastness before using any solvents.

Prestik should be kept away from small children as it can present a choking hazard if accidentally swallowed.

Most adhesives have a shelf life of at least 12 months if stored in a cool (below 25°C), dry place in its original moisture-tight container. If the material is kept beyond the recommended shelf life, it is not necessarily unusable, but a check should be performed to observe whether the product is still workable, apply-able and uncured.

Most solvent based adhesives are flammable. Always work in a ventilated area and do not breathe in vapours. Avoid exposing the product to any ignition sources. Do not smoke when working with adhesives.

Clean excess liquid school glue with warm soapy water when still wet.

The shelf life of adhesives varies from product to product, but typically ranges between one and two years from the date of manufacture when unopened and stored correctly in dry conditions - usually between +5°C and +25°C. Once opened, the life of the product will be more limited – this is dictated by variables including the type of adhesive, how it is stored, and how much adhesive is left unused. For more information, refer to the product’s Technical Data Sheet.

Adhesive residue from most sticky tapes can be removed with acetone. Always test a small area first.

Before applying glue, ensure that all surfaces are of sound nature and clean, dry and free from dust, grease or any other contamination.

Clean with warm soapy water or wet wipes.

We recommend storing in a refrigerator to lengthen the shelf life. Refrigerated packaging should be allowed to return to room temperature prior to use.

Rinse your fingers immediately with plenty of warm soapy water and do not pull on the skin that has been glued. If glue remains after using warm soapy water, it will often de-bond within a couple of days due to general wear and tear and the natural oils in the skin. If skin irritation occurs, consult a doctor.

Wet and dried adhesive on applicator tools can be cleaned with acetone, thinners or parrafin. Please refer to the Technical Data Sheet of the specific product for more information.

Cured sealant must be removed mechanically with a sharp knife or chemically with Bostik Silicone Stripper. Always test on a small surface first.

Uncured silicone can be removed from the hands or tools using a clean solvent soaked cloth, e.g. turpentine or paraffin. If removing uncured silicone from clothing, check fabric colour fastness before applying solvents.

No. Alcohol based cleaners should not be used for cleaning surfaces as alcohol inhibits the cure of silicones. Soaps or detergents used to clean the surface must be rinsed away thoroughly with clean water to ensure that all traces of the soaps are removed before sealing.

To maximize the shelf life of an opened silicone cartridge, we recommend that the nozzle be removed and a piece of plastic placed over the cartridge tip after which the nozzle must be screwed back on. A large screw inserted into the nozzle tip also helps to extend the life. Store in a cool environment.

Bostik Mounting Tape Strips are designed for one-time use. Attempting to reuse them may result in reduced adhesion and may not securely mount the object. For repositioning, it's recommended to use new Mounting Tape Strips for optimal results.

While Bostik Mounting Tape is designed for use on smooth surfaces such as tiles, metal, wood, glass, and fiberglass, it's not suitable for rough or crumbly surfaces. Ensure the surface is clean, dry, and free from dust or grease for optimal adhesion.

To remove mounted objects, carefully peel them off the surface. Start from one corner and gently pull away, avoiding sudden jerks that could damage the surface. If residue remains, use an adhesive remover like our Bostik Glu Go or rubbing alcohol to clean the area.
