Pump & Spray Machines

Pump and spray machines are designed for applying a variety of construction coatings across projects involving flooring, rendering, masonry, and plastering. These machines continuously pump material through a hose to a spray gun, allowing for smooth, consistent application of both internal and external coatings, cutting down on manual labour and increasing productivity on site.

Pump and spray machines use either a screw or diaphragm pump system to draw material from a hopper or container. The material is then pressurised and pushed through a hose to the spray gun. At the nozzle, compressed air or mechanical pressure helps atomise the material, producing an even, controlled spray pattern. These machines are ideal for medium to high-viscosity materials such as thin coat render, textured coatings, masonry paints, and bonding agents.

Setup time varies depending on the model and site conditions, but most REFINA pump and spray machines can be assembled and ready to use within 10–20 minutes. This includes connecting the hoses, priming the pump, and setting the correct spray pressure. With user-friendly controls and straightforward assembly, REFINA pump and spray machines are designed to minimise downtime and maximise output.

Yes, pump and spray machines are ideal for spraying render, especially thin coats, silicone, and acrylic renders. They provide a fast and consistent way to apply render across large surface areas, reducing fatigue and manual errors. The REFINA STX407 Spray Pump is specifically engineered for this type of work. However, this spray pump is not suitable for spraying basecoat or any sand and cement mixes.

Key features of the STX407 include:

• Optimised for high-precision render spraying
• Suitable for 1–2 coat systems
• Easy to clean and maintain

Spray pressure varies across REFINA’s pump and spray machine range depending on the material and application type. Please see a brief guide below:
