Paint Sprayers
Spray gun kit is for when brushing and rolling won't cut it on time or finish, especially on big walls, ceilings, fences, and doors.
On refurbs and new builds, a decent spray gun lays paint fast and even, without lap marks and heavy roller texture. Pick the right paint spray machine for the coating, keep it clean between colours, and you'll get a proper finish without wasting half the day cutting in.
What Are Spray Guns Used For?
- Spraying fresh plastered walls and ceilings to get a consistent coat quickly, especially where a roller would leave texture or miss tight corners.
- Coating timber fencing, sheds, and cladding without dragging a brush through knots and rough grain, so you get better coverage in less time.
- Finishing doors, skirting, architrave, and fitted units when you need a smoother look than brush marks, particularly on gloss and satin systems.
- Hitting awkward surfaces like radiators, balustrades, and textured areas where a brush is slow and a roller cannot physically reach properly.
- Turning out repeatable results on snagging and touch-up runs by keeping a dedicated spray gun set up for the same product, rather than constantly swapping sleeves and trays.
Choosing the Right Spray Gun
Match the spray gun to the coating and the size of the job, because the wrong setup either spits, runs, or wastes paint in the air.
1. Cordless paint sprayer vs electric paint spray gun
If you are moving room to room, up steps, or working outside on fences, a cordless paint sprayer saves you dragging leads through wet paint. If you are doing long, steady runs indoors, a corded electric paint spray gun is often the simpler choice for uninterrupted spraying.
2. What you are spraying and how thick it is
If you are spraying heavier coatings like some masonry paints, you need a paint spray machine that can handle thicker material without constant thinning and blockages. If you are spraying thinner finishes like stains, varnishes, or lacquers, a lighter spray gun setup is easier to control and keeps the finish cleaner.
3. Control and clean-up on real jobs
If you are working in occupied spaces, prioritise spray guns with predictable adjustment so you can keep overspray down and avoid coating everything in the room. If you are swapping colours or products, pick a setup you can strip and clean quickly, because a blocked gun costs more time than it saves.
Who Uses Spray Guns on Site?
- Decorators and professional painters use spray guns to get speed on big areas and a flatter finish on trim, especially when the programme is tight.
- Joiners and kitchen fitters reach for an electric paint spray gun for doors, panels, and built-ins where brush marks look rough under site lighting.
- Maintenance teams and landlords use a cordless paint sprayer for quick turnarounds in empty properties, because it cuts time on ceilings, doors, and woodwork.
- Fencers and landscapers use a paint spray machine for stains and treatments across long runs, where brushing would take all day and still look patchy.
The Basics: Understanding Spray Guns
A spray gun is only as good as its setup. Get the basics right and you get even coverage and less mess; get them wrong and you get runs, dry spray, and constant clogging.
1. Atomisation and finish quality
The gun breaks paint into a fine mist. Better atomisation gives a smoother finish on doors and trim, while poor atomisation leaves a gritty look and makes you overcoat to hide it.
2. Flow rate and spray pattern
You adjust how much paint comes out and the shape of the fan. Wide fan and steady flow suits walls and ceilings; a tighter pattern with less flow helps on edges, spindles, and detailed woodwork without flooding it.
3. Viscosity and filtering
Paint that is too thick will spit and block, and paint with lumps will ruin the tip and the finish. On site, the simple win is to strain paint before it goes in the cup so the spray stays consistent from start to finish.
Spray Gun Accessories That Save Time on Site
The right extras stop blockages, cut clean-up, and keep your finish consistent across a full day of spraying.
1. Spare tips and nozzles
A spare tip keeps you working when one starts to wear or blocks mid-job, instead of downing tools while you try to rescue it with pins and thinners.
2. Paint strainers and filters
Straining paint before it hits the gun stops dried bits and lumps wrecking the spray pattern, which is usually what causes spitting and a rough finish on the last coat.
3. Cleaning kits and spare cups
A proper cleaning kit and a spare cup mean you can swap products faster and clean the gun properly at the end of the day, rather than leaving it to clog up overnight.

Spray Gun FAQs
Do professional painters use spray guns?
Yes, plenty do, especially for speed on big areas and for a flatter finish on doors and trim. The difference is the prep and control; pros mask properly, manage overspray, and keep the gun clean so it sprays consistently all day.
Can you put any kind of paint in a spray gun?
No, not straight out the tin. Some paints are too thick, some need thinning, and some need filtering to stop lumps blocking the tip. Always check the coating spec and do a quick test spray first, because forcing thick paint through is how you get spitting, runs, and constant clogs.
Are cordless paint sprayers actually worth it, or do they run out too fast?
They are worth it when access is the problem, like fences, stairwells, and room-to-room work where leads slow you down. Just be realistic: spraying drains batteries quicker than drilling, so have spare batteries ready if you are doing full rooms.
How do you stop a spray gun making a mess with overspray?
Keep the gun at a steady distance, use the right fan width, and do not crank the flow up to compensate for thick paint. On site, the biggest win is proper masking and keeping doors shut, because overspray travels further than you think, especially in warm, dry rooms.
What is the main reason spray guns clog up mid-job?
It is usually paint that is too thick, unfiltered paint, or stopping for a break without clearing the tip. If you are pausing, keep things moving by clearing the nozzle and not letting paint dry in the gun, because that is when the pattern goes patchy and starts spitting.
