In order to get the best results form your adhesive tape you need to ensure that you apply it correctly, always follow any manufacturer instructions (if supplied).
All surfaces should have no flaky or loose areas and should be completely free from oil, grease, moisture, dust and release agents. Ideally surfaces should be cleaned with a solvent such as Pronatur Orange Solvent. Porous surfaces may need to be sealed prior to application. All surfaces should be dry before application.
When applying adhesive tapes, unless it’s an all-weather adhesive, the substrate (items you are sticking together) temperature should not be less than 15°C. Using adhesive tape in temperatures lower than 15°C can result in hardening of the adhesive and prevent the ultimate bonding strength being reached. Ideal application temperature is between 20 to 40°C. Note that an adhesive tape with the ability to withstand temperatures lower than 15°C does not mean it can be applied in those temperatures.
There are some adhesive tapes that have been designed to be applied in lower temperatures such as our Polly Tunnel Repair Tape.
Pressure Sensitive Adhesive (PSA)
Unless specified, all adhesive tapes use PSA, basically they rely on you applying pressure to them in order to activate the adhesive. Firm pressure and 100% surface contact is key to achieving maximum bond strength. Pressure should be applied evenly and where possible with a roller to ensure there are no air bubbles, important on wide tape.
PSA tapes may take up to a couple of days to reach ultimate adhesion, although this can usually be accelerated by exposing the tape to elevated temperatures for a short period of time.
