Paint Spraying

About Paint Spraying

Paint spraying equipment revolutionises decorating and finishing work by delivering professional results in a fraction of the time required for traditional brushes and rollers. Whether tackling interior walls, exterior cladding, furniture restoration or automotive refinishing, powered paint sprayers provide consistent, even coverage with minimal effort. The technology has evolved significantly, with modern systems offering precise control over spray patterns, flow rates and finish quality, making them indispensable tools for both trade professionals and ambitious DIY enthusiasts.

Tooled-Up.com offers paint spraying equipment divided into two main categories: compact paint spray guns and more substantial paint spray systems. Paint spray guns feature integrated paint canisters and lightweight designs, ideal for smaller projects, touch-up work and situations requiring manoeuvrability such as ladder work. Paint spray systems incorporate separate motor housings with larger capacity tanks, delivering higher power output and extended runtime for demanding commercial applications. Both types can handle various materials including emulsion, gloss, varnish, lacquer, wood treatments and specialist coatings, though material viscosity and dilution requirements vary between models.

The primary advantage of paint spraying lies in speed and finish quality. A competent operator can achieve smooth, professional results on complex surfaces—such as radiators, railings and intricate joinery—where brushes would leave visible marks. However, these benefits come with considerations: paint sprayers consume more material than traditional methods due to overspray, require thorough masking and preparation, and demand meticulous cleaning after each use. Understanding these trade-offs helps users select appropriate equipment and techniques for specific applications.

Jargon Buster

• HVLP (High Volume Low Pressure) – A spraying technology that uses high air volume at low pressure to atomise paint, resulting in reduced overspray, better material transfer efficiency and finer finish quality compared to conventional spray guns. Particularly suited to detailed finishing work and indoor applications.
• Airless Spraying – A system that forces paint through a small nozzle at extremely high pressure (up to 250 bar) without using compressed air, creating atomisation through pressure alone. Delivers rapid coverage on large surfaces and handles thicker materials without thinning, making it ideal for exterior walls and commercial decorating.
• Viscosity – The thickness or flow resistance of a coating material. Paint sprayers have maximum viscosity ratings, and materials exceeding this threshold require thinning with appropriate solvents or water to prevent clogging and ensure proper atomisation.
• Spray Pattern – The shape of the paint distribution as it exits the nozzle, typically adjustable between horizontal, vertical and circular patterns. Selecting the correct pattern orientation for the surface being sprayed improves efficiency and finish quality.
• Nozzle Size – The diameter of the spray tip opening, measured in millimetres or thousandths of an inch, which determines the volume of material discharged and the fineness of atomisation. Smaller nozzles (1.0-1.5mm) suit lacquers and fine finishes, whilst larger sizes (2.0-3.0mm) handle thick emulsions and primers.
• Overspray – Paint particles that miss the intended surface and become airborne, potentially settling on surrounding areas. Proper masking, extraction and respiratory protection are essential when working with spray equipment, particularly in confined spaces.

How to Choose the Right Paint Spraying Equipment

Project Scale and Frequency – Occasional domestic users redecorating rooms or painting garden furniture will find compact spray guns sufficient, whilst professional decorators completing multiple jobs weekly benefit from the power, capacity and durability of dedicated spray systems. Consider annual usage hours when assessing value and reliability requirements.

Material Types – Identify the coatings you'll predominantly spray. Thin materials like stains, lacquers and water-based treatments work with most equipment, but thick emulsions, masonry paints and textured coatings demand higher-powered airless systems. The range available from Tooled-Up includes models suitable for various viscosities, with specifications clearly indicating compatible materials.

Power Source – Mains-powered 240v models deliver consistent performance for extended periods, ideal for site work with reliable electrical supply. Cordless battery-powered units from brands like Makita, DeWalt and Milwaukee offer unmatched portability for exterior work, remote locations and situations where trailing cables pose trip hazards or inconvenience.

Tank Capacity – Integrated canisters on spray guns typically hold 600-1000ml, requiring frequent refills on larger projects. Separate systems feature 2-5 litre tanks enabling uninterrupted coverage of entire rooms or building exteriors. Balance capacity against portability based on typical job sizes.

Adjustability and Control – Quality sprayers offer adjustable flow rates, spray patterns and air pressure, allowing fine-tuning for different materials and applications. Look for clear, accessible controls and pressure gauges on professional-grade equipment. Budget models may have limited adjustment, restricting versatility.

Cleaning and Maintenance – Consider disassembly ease and component accessibility. Quick-release mechanisms, dishwasher-safe parts and included cleaning brushes reduce downtime between colours or materials. Professional users should prioritise models with readily available spare nozzles, seals and filters.

Brand Reputation and Support – Established manufacturers like Wagner, Bosch and Earlex provide comprehensive documentation, replacement parts availability and customer support. Professional-grade equipment from power tool specialists often integrates with existing battery platforms, maximising investment in cordless ecosystems.

Safety Information

Paint spraying creates fine airborne particles and solvent vapours that pose serious health risks without appropriate precautions. Always work in well-ventilated areas or outdoors when possible, and wear respiratory protection appropriate to the materials being sprayed—disposable dust masks are insufficient for solvent-based coatings. Consult COSHH data sheets for specific products to identify required protective equipment.

Protect eyes with safety goggles or full-face shields, as paint mist can cause severe irritation and long-term damage. Wear protective coveralls, gloves and head coverings to prevent skin absorption of hazardous chemicals. Ensure mains-powered 240v equipment is connected through RCD protection to guard against electric shock, particularly important in damp conditions or when working outdoors.

Airless sprayers operate at extremely high pressures capable of injecting paint beneath skin, causing severe injuries requiring immediate medical attention. Never point equipment at any body part, and never attempt to clear blockages by spraying into your hand. Follow manufacturer lockout procedures before performing maintenance or nozzle changes.

Maintain adequate fire safety awareness when using flammable solvent-based materials. Eliminate ignition sources including naked flames, smoking materials and spark-producing equipment from the work area. Store materials and clean equipment outdoors or in well-ventilated spaces away from heat sources. Dispose of solvent-soaked rags and masking materials responsibly to prevent spontaneous combustion.

Frequently Asked Questions

Do I need to thin paint before using a sprayer?
This depends on the paint viscosity and sprayer type. Airless systems handle thick emulsions straight from the tin, whilst HVLP spray guns usually require thinning by 10-20% with water (for water-based paints) or appropriate solvents. Consult the sprayer's manual for maximum viscosity ratings and use a viscosity cup to test materials. Thinning too much reduces opacity and coverage, requiring additional coats.

How much more paint does spraying use compared to brushes?
Expect to use 20-40% more paint when spraying due to overspray and material lost during equipment cleaning. However, the time savings and superior finish quality often justify the increased material cost for professionals. Careful masking, proper technique and appropriate nozzle selection minimise waste. For small touch-up work, brushes remain more economical.

Can I spray exterior masonry paint with standard equipment?
Thick masonry paints require powerful airless systems capable of handling high-viscosity materials—standard spray guns lack sufficient pressure. Dedicated exterior sprayers available at Tooled-Up can handle masonry coatings, but verify compatibility before purchasing. Some masonry paints contain aggregates that may block nozzles or require specific tip sizes.

How long does cleaning take after spraying?
Thorough cleaning typically requires 15-30 minutes depending on equipment complexity and material type. Water-based paints clean more easily than solvent-based products. Never leave paint to dry in equipment—even brief delays cause permanent blockages. Invest time in proper cleaning to maintain performance and extend equipment lifespan. Quick-clean systems on professional models reduce downtime significantly.

Are cordless paint sprayers powerful enough for professional use?
Modern cordless sprayers from Milwaukee, DeWalt and Makita deliver impressive performance for many professional applications, particularly smaller projects, site touch-ups and exterior work without electrical supply. However, they don't match the sustained power and tank capacity of mains-fed systems for high-volume commercial decorating. Battery technology continues advancing, narrowing this performance gap annually.
