HVLP (High Volume Low Pressure)

A spray technology that atomises paint using high air volume at low pressure, resulting in significantly reduced overspray, better transfer efficiency, and more controlled application. Ideal for detailed work, furniture finishing, and enclosed spaces where overspray containment is essential.

Airless Spray

A powerful system that pressurises paint directly through a precision nozzle without using compressed air, creating a forceful spray pattern suitable for thick coatings and large-scale commercial projects. Offers faster coverage rates but requires comprehensive masking due to increased overspray potential.

Spray Pattern

The shape of paint distribution from the nozzle, typically adjustable between horizontal, vertical, and circular patterns to suit different surfaces and applications. Quality systems offer tool-free pattern adjustment with clear visual indicators for each setting.

Flow Rate/Output

Measured in ml/min, this specification indicates the volume of paint the system can spray per minute. Higher flow rates suit large walls and ceilings, whilst lower rates provide superior control for detailed joinery work and furniture finishing.

Viscosity Cup

A calibrated measuring tool supplied with many spray systems to assess paint thickness. Paint is timed as it flows through the cup's orifice to determine whether thinning is required for optimal atomisation and spraying performance with your specific system.

Nozzle/Tip Size

The diameter of the spray opening, measured in millimetres. Smaller nozzles (1.0-1.5mm) suit thin coatings like lacquers, stains, and detailed work, whilst larger nozzles (2.0-2.5mm) handle thicker materials including masonry paint, emulsion, and high-build primers.

Safety Information

Respiratory Protection: Always wear appropriate respiratory protection when spraying. Paint mist contains fine particles that can be inhaled deep into the lungs, potentially causing respiratory irritation or long-term health effects. Use PPE rated for the specific coating being applied – water-based paints may require different protection levels than solvent-based products or two-pack systems. Work in well-ventilated areas or use mechanical extraction equipment to minimise airborne particles. Follow COSHH (Control of Substances Hazardous to Health) regulations regarding hazardous substances and maintain adequate ventilation throughout application and drying periods. Never spray in confined spaces without proper extraction and respiratory equipment.

Eye and Skin Protection: Wear safety goggles or a full-face shield to prevent paint mist contacting eyes, which can cause irritation or chemical burns depending on coating type. Protect skin with appropriate nitrile gloves, long sleeves, and disposable coveralls. Many paints contain chemicals including isocyanates, solvents, and biocides that can cause irritation, allergic reactions, or dermatitis through skin contact. Barrier cream provides additional protection for exposed skin areas. Wash thoroughly after use and never eat, drink, or smoke whilst handling paint products.

Electrical Safety: When using mains-powered 240v equipment, ensure cables remain in good condition without damage to insulation, exposed conductors, or cracked plugs. Use an RCD (Residual Current Device) protection rated at 30mA when working in damp conditions, outdoors, or in potentially hazardous environments. Keep electrical components away from paint spillage and ensure equipment is switched off and unplugged when cleaning, changing nozzles, or performing maintenance. Comply with BS 7671 wiring regulations on commercial site work and maintain portable appliance testing (PAT) records for professional equipment.

Fire and Flammability: Many paints, thinners, and solvents are highly flammable and produce vapours that can ignite explosively. Never spray near naked flames, sparks, pilot lights, heat sources, or electrical equipment that could cause ignition. Ensure adequate ventilation to prevent vapour accumulation, particularly in basements, roof spaces, and enclosed rooms. Store paints and solvents safely according to manufacturer instructions, local fire regulations, and HSE guidance. Keep appropriate fire extinguishers accessible when working with flammable materials and ensure escape routes remain clear.

Preparation and Containment: Thoroughly mask and protect areas not being painted using appropriate materials. Overspray travels considerably further than most users expect and can settle on surfaces several metres away, affecting floors, furniture, fixtures, and vehicles. Use proper masking film, tape, and drop cloths rated for spray applications. Clear the work area of unnecessary items and ensure good lighting to identify potential hazards. Warn other tradespeople and building occupants when spraying is taking place.

Frequently Asked Questions

Do I need to thin paint before using a spray system?
This depends on both the paint viscosity and your spray system type. Most water-based emulsions require some thinning for HVLP systems, typically 5-10% water addition for optimal atomisation. Use the viscosity cup supplied with your system to measure paint flow time and follow manufacturer recommendations precisely. Airless sprayers like the Wagner Control Pro series often handle thicker paints straight from the tin without thinning. Always test spray pattern on cardboard or spare material before starting your actual project to ensure optimal consistency, coverage, and finish quality. Over-thinning reduces opacity and may require additional coats.

How long does it take to clean a paint spray system?
Cleaning time varies significantly by system design and paint type. Modern quick-clean systems like many Bosch models disassemble easily without tools and can be cleaned in 5-10 minutes for water-based paints using just warm soapy water. Solvent-based coatings require more thorough cleaning with appropriate thinners or brush cleaners, potentially taking 15-20 minutes for complete removal. Never leave paint to dry in the system – clean immediately after use to prevent blockages and maintain performance. Some components are dishwasher-safe, making cleaning even more convenient for DIY users. Professional decorators often clean between colours during multi-room projects to maintain efficiency.

Can I use the same spray system for different types of paint and coatings?
Yes, most spray systems handle various coatings including emulsion, gloss, varnish, wood stain, primer, and preservative, provided you select appropriate nozzle sizes and thin materials correctly for your specific system. However, thorough cleaning between different paint types is essential, particularly when switching between water-based and solvent-based products to prevent contamination and finish defects. Keep separate nozzles for fine finishes and rough coatings to maintain optimal performance and spray pattern quality. Check your system's specifications for compatible materials, viscosity limits, and any restrictions on particular coating types like cellulose or two-pack systems.

Are cordless paint spray systems powerful enough for professional use?
Modern 18v cordless spray systems from manufacturers like Bosch and Einhell offer impressive performance suitable for many professional applications, with brushless motors delivering power comparable to corded equivalents. They excel on site work where mains power access is limited, scaffolding applications, outdoor projects, and multi-location contracts. Battery runtime varies with paint viscosity, flow settings, and ambient temperature – typically 15-40 minutes per charge for standard 2.0-4.0Ah batteries. Professionals often invest in higher-capacity batteries (5.0Ah or above) and keep multiple packs charged for uninterrupted work throughout the day. Corded 240v systems still offer advantages for extended indoor projects with readily available power and eliminate battery charging downtime.

What surface preparation is needed before spray painting?
Spray systems reveal surface imperfections more readily than brush or roller application, so thorough preparation is crucial for professional results. Clean surfaces to remove dirt, grease, dust, and loose material using appropriate cleaners or sugar soap. Fill cracks, holes, and dents with suitable filler and sand smooth when dry, feathering edges to blend with surrounding surfaces. Prime bare wood, metal, plaster, or MDF according to paint manufacturer instructions to ensure proper adhesion and prevent absorption variations. Sand existing paintwork with 120-180 grit abrasive to provide a key for new coatings. Comprehensive masking of areas not being painted is essential – spray mist travels considerably further than brush splatter and settles on unprotected surfaces several metres away. The preparation time investment delivers superior finished results and reduces rectification work.
