Frequently Asked Questions
Can I use epoxy resin to fix any windscreen crack?
Epoxy resin is effective for minor chips and small cracks, especially those caused by small stones. For large, complex, or spreading cracks, professional replacement is recommended for safety reasons.Repairs are best suited to shallow chips. Deep damage that penetrates the entire thickness of the glass should not be filled with resin.
How long should I wait before using my car after a repair?
Most fast-setting epoxies allow light handling in 5–10 minutes, but the windscreen should not be cleaned or subjected to stress until full cure—typically several hours. Check product guidelines for specific times.
Will the epoxy resin affect the clarity of my windscreen?
High-quality epoxies designed for glass dry clear, restoring transparency to the repaired area. Proper mixing and curing are essential to minimise any visual impact.
What's the most common mistake with windscreen epoxy repairs?
Incomplete cleaning and improper resin application are frequent issues. Always ensure the surface is spotless, and take care when mixing and applying resin to avoid bubbles or streaks.
Is it necessary to sand or polish the repaired area post-cure?
Usually, a gentle scrape with a plastic blade is sufficient to remove excess epoxy. Polishing may help if the area appears slightly hazy, but aggressive sanding can scratch the glass.
How do I remove excess, cured epoxy from the glass?
Use a plastic razor blade or scraper, avoiding metal tools to prevent scratching. Always remove residue gently to preserve the windscreen’s integrity.
