Paint Sprayer Job Guide

While the application itself is rapid, the success of a spray job relies heavily on meticulous preparation and specialist equipment. This guide outlines what to expect when hiring a professional spray technician and the realistic costs involved for high-end results.

What Does the Work Involve?

• Surface Preparation: Thorough cleaning, degreasing, and mechanical sanding to ensure the paint bonds correctly.
• Extensive Masking: Using tape, paper, and plastic sheeting to protect every surface not being painted, including windows, floors, and sockets.
• Priming: Applying specialist high-adhesion or "stain-blocking" primers, particularly for wood or previously painted surfaces.
• Equipment Calibration: Setting up Airless or HVLP (High Volume Low Pressure) sprayers with the correct tip size and pressure for the specific paint type.
• Multi-Coat Application: Spraying multiple thin, even layers to achieve a durable finish without drips or "runs."
• Site De-masking: Carefully removing protective coverings once the paint is touch-dry to reveal crisp, clean lines.

Typical Costs

The primary factor affecting the price is the level of masking required. An empty house is significantly cheaper to spray than a furnished one, as the technician spends less time protecting items and more time applying paint.

Pro Tip: Always ask if the quote includes "back-rolling." For internal walls, some pros spray and then lightly roll to provide a subtle texture that is easier to touch up later.

How Long Does It Take?

• Single Empty Room: 1 day (4 hours masking, 1 hour spraying, 2 hours drying/de-masking).
• Average Kitchen Refresh: 3 to 5 days, including off-site spraying of removable doors.
• Full 3-Bed House Interior: 4 to 7 days, depending on the number of coats and woodwork involved.
• External Masonry Spraying: 2 to 3 days, strictly subject to dry, calm weather conditions.

DIY or Professional?

While you can rent a spray gun, the learning curve is steep. Professional-grade finishes require expensive pumps (often costing £2,000+) that atomise paint more finely than DIY models. Without the correct technique, DIYers often face "orange peel" textures, heavy runs, or significant overspray damage to furniture and flooring. For kitchen cabinets or UPVC, a professional is essential to ensure the paint doesn't peel within months.

Choosing the Right Tradesperson

• Specialism: Ensure they are a dedicated "Spray Technician" rather than a general painter who occasionally uses a spray can.
• Portfolio: Ask for close-up photos of "internal" corners and edges; these are the hardest areas to spray perfectly.
• Cleanliness: A good sprayer will discuss their extraction and dust-containment methods before starting.

Questions to ask:

• What type of spray system will you use (Airless, HVLP, or XVLP)?
• How do you manage overspray and paint mist in a furnished home?
• Do you provide a guarantee against the paint peeling or flaking?
• What brand and specific line of paint do you recommend for this substrate?

UK Regulations

• VOC Regulations: All paints used must comply with UK Volatile Organic Compound limits for indoor air quality.
• Working at Height: For exterior spraying, contractors must follow the Work at Height Regulations 2005, often requiring towers or professional scaffolding.
• Waste Disposal: Professional decorators should have a waste carrier licence to dispose of paint tins and contaminated masking materials legally.

Common Problems

• Overspray: Fine paint mist can travel through gaps in doors or windows; ensure the contractor uses high-quality masking tape and "zip-wall" barriers.
• Poor Adhesion: If the surface isn't degreased (especially in kitchens), the spray will "fish-eye" or peel away shortly after drying.
• Orange Peel Texture: Caused by incorrect pressure settings or paint that is too thick, resulting in a bumpy, pitted finish.
• Tailing: Visible lines in the finish caused by a clogged spray tip or inconsistent pressure.

Frequently Asked Questions

Does spray painting use more paint than a brush and roller?

Yes, spraying typically uses 20% to 30% more paint. This is due to "transfer efficiency"—some paint is lost as mist in the air, and the sprayer applies a thicker, more consistent coat than a brush.

Can you spray paint over old kitchen cabinets?

Absolutely. It is the most common way to modernise a kitchen. As long as the cabinets are cleaned with sugar soap and a specialist primer is used, the finish is incredibly durable and looks brand new.

Is the paint mist dangerous to breathe?

Yes, paint mist contains particulates that should not be inhaled. Professionals wear respirators (P2 or P3 grade) and use extraction fans. Homeowners and pets should stay out of the immediate area until the mist has settled.

Will the finish be easy to touch up if it gets scratched?

Sprayed finishes are harder to touch up than rolled ones because a brush mark will stand out against the perfectly smooth surface. It is best to keep a small amount of the original paint and use a fine artist's brush or a mini-foam roller for repairs.

Can you spray outside in the wind?

No. Even a light breeze can carry paint mist onto neighbours' cars or windows. Professional sprayers will only work on calm days or will use extensive screening to contain the spray.
