Can You Paint uPVC Windows Inside?

Looking to refresh your home interior without replacing windows? Painting uPVC windows inside is a practical and cost-effective way to modernise your living space. With the right preparation and materials, you can achieve a smooth, professional finish that looks brand new.

At J&D Sprayers & Makeovers, we specialise in uPVC spraying—both inside and out—for homes and businesses across Scotland.

 

✅ Can You Paint uPVC Windows Indoors?

Yes, you can! Painting interior uPVC windows is absolutely possible and can dramatically improve the look and feel of your home. However, indoor spraying comes with its own challenges—ventilation, masking, and achieving a smooth finish in a confined space all require care.

 

Step-by-Step: How to Paint uPVC Windows Inside

Here’s how the process works when done correctly:

1. Clean the Surface Thoroughly

Remove dust, grease, and grime using soap and warm water. Dry the surface completely.

2. Light Sanding for Adhesion

Gently sand the uPVC frame to “key” the surface. This helps the primer and paint adhere better. Wipe off all dust before moving on.

3. Apply a uPVC-Compatible Primer

Use a high-adhesion primer specifically designed for uPVC. This base layer ensures durability and prevents peeling.

4. Spray or Paint in Thin Coats

Apply paint using a high-quality sprayer or brush in light, even layers. Allow each coat to dry before applying the next.

5. Allow Time to Cure

Leave the windows untouched for 24–48 hours to let the paint cure fully.

💡 Pro Tip: Always ensure good ventilation. Open windows where possible and use a mask to avoid inhaling paint fumes.
