- Low temperatures bring a risk of condensation forming on the surface which will prevent bonding. In such conditions, gently warm the surface of the glass to above 10°C using a hot air gun. Take care not to overheat and crack the glass.
- The fine surface pores in glass can trap impurities and moisture, making bonding difficult. That’s why we always recommend priming the surface with Silane Glass Primer.
- Allow the primer to dry (naturally, or with the gentle application of warm air) and apply lettering while glass remains warm.
- Apply lettering as in Bonding lettering to glass below.
- Create some removable markings to help you align the letters prior to fixing. This is especially useful with high strength bonding tapes as they possess good initial tack. Removing mis-aligned letters could result in damage.
- If the glass cools as you progress, re-apply gentle heat before you fix each letter.
Once lettering is applied with firm pressure you’ll achieve 60%-70% bond strength. Ultimate bond strength will be reached in 48-72 hours. If you’re in any doubt as to whether the initial bond strength will be sufficient to support the weight of the lettering, apply some strong masking tape until the NovaBond has achieved ultimate bond strength.
