UPVC Spraying – Common Questions & Answers
Here’s a clear, practical guide tailored for UK homes, lodges, and doors/windows:
❓ What is UPVC spraying?
✅ A professional coating process that changes the colour of existing uPVC windows, doors, frames, and fascia boards. It uses high-quality, flexible paints designed specifically for uPVC — no need to replace the whole unit.
❓ How long does it last?
✅ 10–15+ years when prepped and applied correctly. It won’t crack, peel, fade, or chalk like standard paint. Most reputable firms offer a 5–10 year guarantee.
❓ Can any colour be used?
✅ Yes — thousands of options:
- Popular: Anthracite Grey, Chartwell Green, Black, White, Light Grey, Sage Green, Cream/Beige
- RAL / BS / Farrow & Ball colours available
- Even wood-effect finishes
❓ Is it better than replacing uPVC?
✅ Far cheaper — usually 30–50% less than full replacement.
✅ Faster: done in 1–2 days with minimal mess/disruption.
✅ More eco-friendly: keeps existing frames out of landfill.
❓ Will it damage the original uPVC?
✅ No. The process is non-abrasive and reversible if needed. It seals and protects the original material from weathering.
❓ Can you spray inside and outside?
✅ Yes — most spray both sides for a consistent look. Some do external only to save cost.
❓ How is it done?
1. Clean & degrease: Remove dirt, mould, and silicone residue
2. Light abrade: Slightly roughen surface for adhesion
3. Masking: Cover glass, handles, locks, walls, and brickwork
4. Primer: Special uPVC bonding primer
5. 2–3 top coats: High-quality acrylic or polyurethane paint
6. Clear coat (optional): Adds extra UV protection and sheen
❓ Does it affect window/door function?
✅ No. Hinges, locks, and seals are masked or cleaned — operation stays smooth.
❓ Can you spray old/faded/discoloured uPVC?
✅ Perfect for it. It restores yellowed or weathered frames back to like-new condition.
❓ Is it suitable for composite doors too?
✅ Yes — works great on composite, aluminium, and wood-effect doors as well.
❓ What maintenance is needed?
✅ Very little — just wash down with warm soapy water twice a year. Avoid harsh solvents or jet-washing too close.
