Here are some of the most commonly asked questions about UPVC window spraying:
What is UPVC window spraying?
UPVC window spraying applies a specialized spray coating to the exterior of UPVC windows. The spray contains UV-resistant pigments that adhere to the UPVC surface, creating an opaque, uniform color.
This restores vibrancy and protects against further fading and discoloration. The coating also protects against dirt, grime, and pollution.

Why should I get my UPVC windows sprayed?
There are several benefits to spraying UPVC windows:
- Restores original color that has faded or discolored over time
- Provides long-lasting UV protection to prevent further fading
- Creates a smooth, glossy finish for an aesthetically pleasing look
- Protects against accumulation of dirt and pollutants
- Can significantly delay the need for full window replacement
- Available in a wide range of color options to match existing trim or update the home’s exterior appearance
What is the process of spraying UPVC windows?
UPVC window spraying is a multi-step process:
- Wash windows with soap and water to remove dirt, grime, or existing treatments.
- Abrade the surface using fine sandpaper to create a key for the spray coating.
- Wipe down with solvent to remove any residue and ensure a clean surface for spraying.
- Mask trims, handles, and hinges to protect from overspray.
- Apply specially formulated primer if required.
- Spray on colored topcoat using airless spray equipment. Apply 2-3 thin, even coats allowing proper drying time between coats.
- Remove masking and allow 24 hours for curing before washing or exposing to rain.
Should window glazing be replaced?
Replacing the glazing or glass when spraying UPVC windows is unnecessary. The spray coating is specially designed to bond to UPVC and will not adhere to the glass.
Depending on the condition of existing glazing seals, replacement may be recommended but is only sometimes required.
How long does UPVC window spraying last?
When properly applied by an experienced professional, a high-quality UPVC window spray can last anywhere from 5-10 years before needing to be reapplied.
Factors like coating quality, number of coats applied, and exposure to sun and pollution impact durability. Proper maintenance will maximize longevity.
What is the cost of spraying UPVC windows?
The cost to spray UPVC windows can range from £300 to £1000 depending on the size of the home, number of windows, and coating options selected.
The single-color coating is the most affordable. Additional costs may apply for primer, glazing seals, or repairs. Reputable contractors provide free quotes so you know exactly what to expect.
Can I spray UPVC windows myself?
Homeowners should only spray their own UPVC windows if they have professional experience. The specialized spray equipment, safety precautions, and technical techniques make DIY spraying difficult to achieve quality, long-lasting results. Hiring a professional is recommended.
How can I find the right UPVC window spraying company?
When researching contractors, look for ones experienced specifically with UPVC window spraying. Ask to see examples of previous work and check reviews.
Ensure they use high performance products from reputable brands. Ask about preparation methods, coating thicknesses, warranty and guarantees on workmanship. A reputable company will ensure your windows look immaculate and stay that way for years.
What preparation is required before spraying UPVC windows?
Proper preparation is crucial for achieving best results from UPVC window spraying.
Windows must be thoroughly cleaned with a power washer or soap and water. Any loose paint or coatings must be removed by sanding or using a paint stripper.
Masking tape should be applied to glass, frames, and areas not being sprayed. Priming may also be required if the surface is very weathered. Proper prep ensures maximum adhesion.
What temperature is best for spraying UPVC windows?
UPVC window spraying is ideally performed when temperatures are between 10-25°C. Cooler temperatures can inhibit proper curing and adhesion.
If spraying in cooler temperatures, allow for longer cure times between coats. Hot temperatures can cause coating to dry too quickly. Avoid spraying in direct sunlight or onto hot surfaces.
Can you spray UPVC windows any color?
While a wide range of colors are available, not all colors work equally well on UPVC substrates. Solid, opaque colors tend to perform better than metallics, pearlescent, and lighter translucent shades.
The coating company can best advise on color suitability. Some custom blending may be required to achieve certain hues.

How soon can I close my windows after spraying?
Newly sprayed UPVC windows should be kept open for at least 24 hours to allow proper curing of the coating. Avoid closing, washing, or disturbing fresh coatings until fully hardened.
Contact your coating company for specific cure times based on the products used. Prematurely closing windows can ruin the spray finish.

What maintenance is required after spraying?
While UPVC window spray coatings are low maintenance, the best results come from proper care. Avoid cleaning with abrasive tools, harsh chemicals or scrubbing.
Use only mild soap and water. Reapply protective treatments every 1-2 years. Spot repair any damaged areas immediately to prevent peeling or flaking. Proper maintenance ensures longevity.
