What’s a Render Spray Nozzle?

Render spray nozzles are specialised attachments used for rendering or plastering. They are designed to be connected to a render spray gun to apply render or plaster materials onto wall, ceilings, or other surfaces. Their design allows for efficient and controlled spraying of the render mixture with a much faster application than traditional manual methods.

These nozzles are designed to produce a fine mist or spray of the render material, ensuring even coverage and a smooth finish. They can  be adjustable, allowing for different spray patterns, textures, finishes and flow rates to meet the requirements of various applications. BY using these nozzles, contractors and professionals can save times and effort while achieving high-quality and uniform render finishes.

How to Achieve Different Spray Patterns

To achieve different spray patterns with a render spray gun nozzle, you can make use of adjustable nozzles or interchangeable tips available for various spray guns. Here's a general overview of how to achieve different spray patterns:

  1. Adjustable Nozzles: Some render spray gun nozzles have adjustable settings that allow you to change the spray pattern. The CES Mai Spray Nozzles can be adjusted simply by winding the thread up and down to vary the width of the spray pattern.
  2. Interchangeable Tips: Many render spray gun systems come with a set of interchangeable tips or inserts that can be easily swapped out to achieve different spray patterns. These tips have specific orifices designed to create different patterns.

  • Unscrew the existing nozzle tip or use a wrench/tool to release clip-on designs
  • Select the desired tip or insert from the set of interchangeable options.
  • Screw or clip the new tip securely into place
  • Adjust the pressure and flow rate settings on the spray gun according to the manufacturer's instructions.
  • Test the spray pattern on a test surface or scrap material to ensure the desired pattern is achieved.

Note: The specific method for changing tips or adjusting nozzle settings may vary depending on the brand and model of the render spray gun. It's always best to consult the user manual or manufacturer's instructions for detailed guidance on your specific equipment.

At CES we offer three types of spray nozzle:

  1. Rubber Spray Nozzles
  2. Mai Spray Nozzles
  3. Fine Spray Gun Nozzles

The rubber spray nozzles fit the majority of render spray guns including Putzmeister, Mixer and PFT. They are available in 10mm, 12mm, 14mm, and 16mm and are attached by clipping onto the front of the gun. They fit snugly so may need a bit of force to attach however this reduces the amount of times that they blow off. The 10 and 12mm tips are designed to apply roughcast, 14mm tips are ideal to apply your standard monocouche and the 16mm tips are designed for sand, cement and lime applications.

The Mai Spray Nozzles are designed for the metal Mai Spray heads. These tips screw on by a thread so will sit firmly on your gun without risk of blowing off. You can adjust the spray pattern by winding the thread up and down. These plastic nozzles are supplied in 10mm, 12mm, 14mm and 16mm.

Finally the fine spray gun nozzles are designed for smaller applications and therefore come with smaller orifices. Generally they will spray thin coat and acoustic spray renders although they can spray 8/10mm basecoat. These tips are frequently used with smaller electric machines.
