Frequently Asked Questions

AI
Most silicone sealants require temperatures above 5Β°C for proper curing. Cold weather can significantly delay drying times and reduce initial adhesion. Always check the manufacturer's instructions for minimum application temperatures.
Fast-curing formulas may set in 30 minutes but often require 24 hours for full structural strength. Standard silicones might take longer. Avoid washing the vehicle or exposing the seal to heavy rain until fully cured.
Black sealant is standard for windscreen bonding as it is less visible. However, if you have a light-colored interior or trim, excess squeeze-out may be noticeable. Apply sparingly and clean immediately with a damp cloth before it sets.
