When it comes to applying decorative or protective coatings, achieving a durable and even finish is essential. One of the most effective ways to do this is through airless paint spraying. This technique offers numerous advantages over traditional methods like brushing or rolling, making it a popular choice among professionals and DIY enthusiasts alike. So why isn’t it more widely used? In short—cost.

Airless paint sprayers used to start at around £1,300. These professional-grade units typically delivered up to 300 psi of pressure and supported relatively large spray tips, making them ideal for emulsions, undercoats, gloss finishes and light to medium viscosity protective coatings. However, in the past 10 to 12 years, manufacturers like Wagner have introduced more affordable domestic airless sprayers, with prices starting from around £500—making this technology far more accessible for home use.

Introducing the New Cordless Airless Paint Sprayer from Cactus

Traditionally, airless sprayers required a mains power supply and had a limited hose length, which restricted movement. But imagine the convenience of a cordless solution...

Launched in 2025, the new Cordless 18V Airless Paint Sprayer from Cactus changes the game. Delivering an impressive 2,175 psi and supporting a maximum tip size of 0.016", this powerful machine is more than capable of spraying heavy-duty protective coatings.

Each kit includes:

• 1 x Spray Unit

• 1 x Spray Gun with 2m Hose (supplied with L514 spray tip and shroud)

• 2 x 18V 5.2Ah Batteries (Makita 18V 6Ah compatible)

• 1 x Charger (240V UK plug)

• 1 x Large Waterproof Orange Carry Bag
