Spray Painting Services Guide

For UK homeowners, this method is particularly effective for modernising existing fixtures without the cost of full replacements. However, the quality of the result depends entirely on meticulous preparation and the use of professional-grade equipment like HVLP (High Volume Low Pressure) or airless spray systems.

What Does the Work Involve?

• Site Preparation: Extensive masking of floors, windows, and furniture using tape, paper, and plastic sheeting to prevent overspray.
• Surface Cleaning: Degreasing surfaces (especially in kitchens) and removing dust to ensure the paint bonds correctly.
• Substrate Repair: Filling cracks, sanding surfaces smooth, and applying specialist primers suited to the material (wood, metal, or uPVC).
• Equipment Calibration: Adjusting the spray tip size and pressure settings based on the paint viscosity and the desired finish.
• Application: Applying multiple thin, even coats, allowing for appropriate flash-off times between layers.
• De-masking and Snagging: Carefully removing protective coverings and checking for any imperfections or "dry spray" areas.

Typical Costs

Prices for spray painting vary significantly based on the complexity of the masking required and the type of paint used. Specialist coatings for uPVC or heat-resistant kitchen paints typically cost more than standard emulsion.

Factors affecting the price include the height of the work (requiring scaffolding), the condition of the original surface, and your location in the UK, with London and the South East typically commanding a 20-30% premium.

How Long Does It Take?

• Single Internal Room: 1 day (including masking and two coats).
• Standard Kitchen Respray: 3 to 5 days (often involving off-site spraying of doors).
• uPVC Windows (Whole House): 2 to 3 days depending on weather conditions.
• External Masonry: 2 to 4 days, heavily dependent on access and wind levels.

DIY or Professional?

While DIY spray kits are available, they often lack the pressure consistency required for a smooth finish, leading to "orange peel" textures or drips. Professional sprayers invest thousands in high-end pumps and extraction systems that manage overspray and fumes.

Professional spraying is 80% preparation and 20% application. If you aren't prepared to spend two days masking a single room, hire a professional.

Furthermore, many specialist paints (such as two-pack coatings) contain isocyanates which require specific PPE and ventilation. For anything other than a garden fence, a professional decorator with spray-specific training is highly recommended.

Choosing the Right Tradesperson

• Check Portfolios: Look for close-up photos of "internal corners" and "edges" to ensure there is no pooling or uneven coverage.
• Verify Insurance: Ensure they have Public Liability insurance that specifically covers the use of spray equipment.
• Ask about Dust Extraction: Professional decorators should use HEPA-filtered dust extraction when sanding to keep your home clean.
• Questions to ask:
  • What type of spray system will you use for this specific surface?
  • How many coats of primer and topcoat are included?
  • Do you spray kitchen doors on-site or in a workshop?
  • What brand and line of paint do you recommend for durability?

UK Regulations

• VOC Regulations: All paints used must comply with UK Volatile Organic Compound limits to ensure indoor air quality.
• Working at Height: If spraying exteriors, the contractor must follow the Work at Height Regulations 2005, using stable platforms or scaffolding.
• Waste Disposal: Professionals should be registered waste carriers to dispose of chemical tins and contaminated masking materials legally.

Common Problems

• Overspray: Fine paint mist settling on furniture or cars outside; avoided by rigorous masking and "booth" setups.
• Poor Adhesion: Paint peeling off uPVC or laminate because the surface wasn't properly degreased or "keyed" (sanded).
• Orange Peel: A bumpy texture caused by incorrect pressure settings or paint that is too thick.
• Environmental Interference: Spraying outdoors in wind or high humidity can ruin the finish before it dries.

Frequently Asked Questions

Is spray painting messier than using a brush?

In terms of application, yes, because of the mist. However, a professional spends hours masking every centimetre of the area, meaning your home is often better protected than it would be during a standard brush-and-roller job.

How long does a sprayed kitchen last?

When done professionally with a hard-wearing specialist coating (like a 2K lacquer), a sprayed kitchen can last 10+ years. It is as durable as a factory-finished kitchen from a high-end showroom.

Can you spray paint in the winter?

Internal spraying is fine as long as the property is heated and ventilated. External spraying (uPVC or masonry) is difficult in winter due to moisture levels and the "dew point," which can prevent the paint from curing.

Does spray painting use more paint?

Generally, yes. There is a percentage of "transfer loss" where paint is lost to the air or masking. However, the speed of application usually offsets the extra material cost in lower labour charges for large areas.

Can any paint be sprayed?

Most paints can be sprayed, but they must be "thinned" to the correct viscosity for the machine. Professional decorators prefer trade-grade paints specifically formulated for spray application to ensure a smooth flow.
