Best Airless Paint Sprayer Under £100

The Wagner W 590 FLEXiO consistently receives high marks from UK DIYers for its ability to spray unthinned paint on fences and walls without blocking. The 630W motor provides enough power to atomise thicker paints, and the three spray patterns (horizontal, vertical, round) give you control over coverage. Owner reviews on Amazon UK highlight its reliability for large garden projects and interior walls, with many noting it outperforms cheaper handheld units significantly.

However, some users report that the plastic nozzle assembly can be fragile if dropped, and the unit is heavier than some competitors. For the price, it offers the best balance of power and finish quality. It is best suited for medium to large projects where you want a professional-looking result without investing in a commercial-grade machine.

The Draper Storm Force 550W is a classic budget option that performs admirably for small to medium tasks. Its lightweight design makes it ideal for painting furniture, trellises, and small fences without fatigue. The 550W motor handles standard emulsions and garden paints well, and the adjustable spray pattern gives good control. Aggregated reviews from Screwfix and Amazon show it is a popular choice for first-time sprayer users.

On the downside, the 800ml cup is smaller than the Wagner, meaning more frequent stops to refill. Some owners also note that it struggles with thicker paints like exterior masonry paint unless thinned significantly. For the price, it is a capable tool for lighter DIY duties.

The Wagner W 100 is the smaller sibling of the W 590, designed specifically for smaller DIY tasks like painting chairs, tables, and small garden ornaments. Its 450W motor is less powerful but provides a finer spray pattern for detailed work. Owner reviews praise its low overspray, making it suitable for use in confined spaces or indoors with less masking. The lightweight design reduces fatigue during longer sessions.

However, the 600ml cup is small, and the motor can struggle with thicker paints. It is best used with thinned emulsions or specialist spray paints. If your primary need is small furniture or craft projects, this is a very capable and affordable choice.

The Bosch PFS 5000E is a well-regarded sprayer that sits just under the £100 mark. It features a 500W motor that handles a variety of paints and varnishes, and the 1.0L cup is a good size for medium projects. Owner reviews on Amazon UK and B&Q highlight its ease of use and the included cleaning kit, which simplifies maintenance. It is a versatile tool for painting fences, sheds, and interior walls.

Some users mention that the spray pattern adjustment is less intuitive than the Wagner models, and the unit is noticeably louder. However, for a brand like Bosch, the build quality and after-sales support are strong points. It is a reliable choice for DIYers who want a trusted brand.

The Einhell TC-AS 18/40 Li is a cordless airless paint sprayer that offers freedom from mains power. It is part of the Einhell Power X-Change system, so if you already own Einhell tools, you can use the same batteries. It is ideal for spraying fences, sheds, or furniture where a power cord would be inconvenient. The adjustable spray pattern and 800ml cup are practical for medium jobs.

However, the battery life is limited, and the motor is less powerful than corded alternatives. Owners report that it works best with thin paints and may struggle with thicker emulsions. The need to purchase a battery and charger separately also increases the total cost. It is best for users already invested in the Einhell ecosystem who need occasional cordless spraying.
